1. Slovaquie

La Slovaquie est un pays enclavé d’Europe centrale, bordé par la Tchéquie, l’Autriche, la Hongrie, l’Ukraine et la Pologne. La circulation se fait à droite. Le centre et le nord du pays sont dominés par les Carpates, notamment les Tatras, tandis que des terrains plus bas et plus plats sont davantage présents dans le sud et l’est. Les pentes de montagne, les routes sinueuses et les conditions hivernales changeant rapidement constituent donc des éléments importants en dehors des principaux corridors autoroutiers. Le slovaque est la langue officielle, et les visiteurs doivent s’attendre à ce que les informations écrites sur les panneaux routiers soient principalement en slovaque, aux côtés des symboles européens standard.

Pour les visiteurs, une caractéristique pratique essentielle est la vignette autoroutière électronique slovaque, requise sur certaines sections d’autoroutes et de voies rapides ; il n’existe pas d’autocollant physique sur le pare-brise et toutes les sections autoroutières ne sont pas payantes. Les règles relatives aux pneus hiver pour les voitures particulières sont liées aux conditions plutôt qu’à des dates fixes : des pneus hiver adaptés sont requis sur tous les essieux lorsque la route est recouverte d’une couche continue de neige, de glace ou de givre, ou lorsque de telles conditions peuvent raisonnablement être attendues sur l’itinéraire prévu. La Slovaquie impose également l’utilisation des feux de jour toute l’année et applique une tolérance zéro pour l’alcool aux conducteurs de véhicules à moteur.

AI
De quel côté de la route roule-t-on en Slovaquie ?

Roulez du côté droit de la route et dépassez normalement par la gauche.

Quel est le numéro d’urgence en Slovaquie ?

Appelez le 112 pour l’assistance d’urgence générale. La Slovaquie possède aussi des numéros d’urgence nationaux distincts, mais le 112 permet de joindre les services d’urgence intégrés.

Quelle est la limite d’alcool au volant en Slovaquie ?

La Slovaquie applique une tolérance zéro pour l’alcool aux conducteurs de véhicules à moteur. Ne conduisez pas tant que de l’alcool peut encore être présent dans votre organisme.

Quelle est la limitation de vitesse en agglomération en Slovaquie ?

La vitesse maximale générale en agglomération est de 50 km/h, sauf si des panneaux établissent une autre limite.

Quelle est la limitation de vitesse hors agglomération en Slovaquie ?

Pour une voiture particulière ordinaire jusqu’à 3,5 tonnes, la vitesse maximale générale hors agglomération est de 90 km/h, sauf si une autre limite s’applique.

Quelle est la limitation de vitesse sur les autoroutes en Slovaquie ?

Pour un véhicule à moteur ordinaire jusqu’à 3,5 tonnes, la vitesse maximale générale sur autoroute est de 130 km/h, sauf si des panneaux imposent une autre limite.

Existe-t-il une vitesse minimale sur les autoroutes slovaques ?

Les autoroutes ne peuvent être utilisées que par des véhicules à moteur, et un conducteur doit normalement être capable de circuler à au moins 80 km/h. Des exceptions s’appliquent lorsqu’une vitesse inférieure est nécessaire pour la sécurité, en cas d’embouteillage, pour entrer ou quitter l’autoroute et dans certaines autres situations.

Qui peut utiliser une route pour véhicules à moteur en Slovaquie ?

Une route désignée pour les véhicules à moteur ne peut normalement être utilisée que par des véhicules à moteur ayant une vitesse maximale par construction d’au moins 60 km/h. Les autres usagers y sont interdits sauf lorsqu’ils sont expressément autorisés à traverser ou à passer.

Faut-il une vignette autoroutière en Slovaquie ?

Oui. Les véhicules concernés par le système de vignette doivent disposer d’une vignette électronique valide avant d’utiliser les sections payantes désignées des autoroutes slovaques. Toutes les sections autoroutières ne sont pas soumises à la redevance.

Quels types de vignettes autoroutières sont disponibles en Slovaquie ?

Des vignettes électroniques sont disponibles pour 365 jours, 30 jours, 10 jours ou 1 jour. Pour un ensemble véhicule-remorque dépassant 3,5 tonnes selon les règles M1/N1 et O1/O2 applicables, une vignette distincte pour la remorque peut également être requise.

Faut-il utiliser les feux de jour en Slovaquie ?

Oui. Les véhicules à moteur doivent utiliser les feux de croisement ou des feux équivalents pendant la conduite. Les feux de circulation diurne peuvent être utilisés à la place des feux de croisement lorsque la visibilité est normale.

Les pneus hiver sont-ils obligatoires en Slovaquie ?

Pour les voitures particulières et véhicules utilitaires légers, les pneus hiver sont obligatoires sur tous les essieux lorsque la route est recouverte d’une couche continue de neige, de glace ou de givre. Les conducteurs doivent également équiper le véhicule lorsque, compte tenu de la saison, de telles conditions peuvent raisonnablement être attendues sur l’itinéraire.

Les voitures particulières doivent-elles transporter des chaînes à neige en Slovaquie ?

Il n’existe pas d’obligation générale pour une voiture particulière ordinaire de transporter des chaînes pendant tout l’hiver. Toutefois, lorsque le panneau Chaînes à neige s’applique, des chaînes ou un dispositif équivalent doivent être montés sur au moins un essieu moteur.

Les ceintures de sécurité sont-elles obligatoires en Slovaquie ?

Oui. Toute personne assise sur un siège équipé d’une ceinture ou d’un autre dispositif de retenue obligatoire doit utiliser le système de retenue disponible, sous réserve d’exemptions légales limitées.

Quand les enfants doivent-ils utiliser un dispositif de retenue en Slovaquie ?

Un enfant mesurant moins de 150 cm doit généralement utiliser un dispositif de retenue homologué adapté. Des exceptions particulières existent, et un dispositif dos à la route ne doit pas être utilisé devant un airbag frontal actif.

Les casques de moto sont-ils obligatoires en Slovaquie ?

Oui. Les conducteurs et passagers de motos concernés par la règle doivent porter un casque de moto correctement attaché, sauf pour certaines configurations limitées de véhicules dotés de structures de protection homologuées et de ceintures de sécurité.

Peut-on utiliser un téléphone portable en conduisant en Slovaquie ?

Un conducteur ne doit pas tenir ni utiliser un téléphone portable ou appareil similaire pendant la conduite. L’utilisation est autorisée au moyen d’un système mains libres.

La priorité à droite s’applique-t-elle en Slovaquie ?

Oui. À une intersection où la priorité n’est pas déterminée autrement, un conducteur doit céder le passage à un véhicule venant de droite.

Qui a priorité à un rond-point en Slovaquie ?

Lorsque le panneau Rond-point est combiné avec un panneau Cédez le passage ou Stop à l’entrée, les véhicules déjà engagés sur le rond-point ont priorité. Les conducteurs doivent donc respecter les panneaux de priorité plutôt que se fier uniquement à la forme du carrefour.

Les piétons ont-ils priorité aux passages en Slovaquie ?

Oui. Depuis le 1er septembre 2026, un conducteur doit permettre à un piéton qui s’est engagé sur un passage ou est sur le point de s’y engager de traverser en sécurité. Les conducteurs doivent approcher à une vitesse adaptée leur permettant de s’arrêter si nécessaire. Les piétons ne doivent toutefois pas s’engager sur la chaussée lorsqu’un véhicule approche trop près pour qu’ils puissent traverser en sécurité.

Les conducteurs doivent-ils former un couloir de secours en Slovaquie ?

Oui. Lorsqu’un embouteillage à l’arrêt se forme sur une autoroute ou une route à chaussées séparées hors agglomération comportant au moins deux voies dans le même sens, les conducteurs doivent créer un couloir de secours. Avec deux voies, il se forme entre elles ; avec trois voies ou plus, il se forme entre la voie la plus à gauche et celle immédiatement à sa droite.

Les trams ont-ils une priorité particulière en Slovaquie ?

Oui. Un tram qui croise la trajectoire d’un véhicule circulant à côté de lui dans le même sens a priorité lorsque le tram signale son changement de direction. D’autres règles particulières de priorité des trams peuvent également s’appliquer lorsque des véhicules tournent en traversant les rails.

Quelle distance les conducteurs doivent-ils laisser lorsqu’ils dépassent des cyclistes en Slovaquie ?

La distance latérale suffisante est généralement d’au moins 1 mètre lorsque la vitesse maximale autorisée est de 50 km/h ou moins et de 1,5 mètre dans les autres cas. La même règle couvre également le dépassement des piétons et des conducteurs de petites motos.

Quelle vitesse s’applique à l’approche d’un passage à niveau en Slovaquie ?

À partir de 50 mètres avant un passage à niveau et pendant sa traversée, la vitesse maximale est normalement de 30 km/h. Si l’équipement du passage affiche un feu blanc clignotant, la vitesse maximale est de 50 km/h.

Quel équipement de sécurité une voiture doit-elle transporter en Slovaquie ?

Une voiture particulière ordinaire doit transporter un triangle de présignalisation, un vêtement de sécurité réfléchissant et une trousse de premiers secours homologués. Une roue de secours, une clé de roue et un cric sont également normalement requis, sauf si le véhicule bénéficie d’une solution alternative comme des pneus run-flat adaptés ou un dispositif homologué de réparation des crevaisons.

2. Autoroute

Une autoroute est une route spécialement conçue et signalée pour la circulation motorisée. Les autoroutes disposent normalement de chaussées séparées pour les sens opposés, d’un accès contrôlé par des entrées et sorties désignées, sans accès direct aux propriétés voisines ni croisements à niveau avec d’autres routes, voies ferrées ou chemins.

Des règles de circulation particulières s’appliquent sur les autoroutes. Les usagers autorisés, limitations de vitesse, règles de voie, péages et procédures d’urgence varient selon les pays ; les conducteurs doivent donc respecter la signalisation et la réglementation locales.

How can you recognise a motorway?

A motorway is normally identified by a special motorway sign at its entrance. It commonly has separate carriageways, controlled entrances and exits, and no ordinary intersections or direct access to neighbouring properties.

Who may use a motorway?

Motorways are primarily intended for motor vehicles capable of travelling safely at motorway speeds. Pedestrians, cyclists, animals and certain slow vehicles are generally prohibited, but the exact access requirements differ between countries.

What is the speed limit on a motorway?

There is no universal motorway speed limit. The applicable limit depends on the country, road section, vehicle category and driving conditions. Posted or variable speed-limit signs may replace the general national limit.

How should you enter a motorway?

Use the entrance or acceleration lane to observe motorway traffic and adjust your speed where possible. Enter only when there is a safe gap and follow the local priority and merging rules.

How should you leave a motorway?

Move into the correct lane in good time and signal when required. Enter the exit or deceleration lane before reducing your speed, unless traffic, signs or road conditions require you to slow down earlier.

Which lane should you use on a motorway?

Follow the local keep-left or keep-right rule and any lane-direction signs. Lanes closer to the centre of the motorway are commonly used for overtaking, but lane-use rules differ between countries and vehicle categories.

Can you stop on a motorway?

Voluntary stopping and parking are normally permitted only in designated parking or service areas. Drivers may still have to stop because of congestion, an emergency or another unavoidable situation.

Can you reverse or make a U-turn on a motorway?

Reversing, making a U-turn and driving against the direction of traffic are generally prohibited. If you miss an exit, continue to the next suitable exit.

What should you do if your vehicle breaks down?

Move the vehicle out of the traffic lanes when this can be done safely, activate the hazard warning lights and follow the local breakdown procedures. Leave the vehicle safely, keep away from moving traffic and use a warning triangle or safety vest where required by local law.

What is the difference between a motorway and an expressway?

A motorway normally has the highest level of access control and is governed by specific motorway rules. An expressway may have similar characteristics but may permit different road users or contain lower-standard junctions. The legal distinction varies between countries.

3. Voie rapide

Une voie rapide est une route destinée à assurer efficacement le trafic de transit, généralement à des vitesses plus élevées que sur les routes ordinaires. Les voies rapides disposent souvent d’un accès limité, de plusieurs voies, de chaussées séparées ou de carrefours dénivelés, mais leur conception et leur statut juridique varient selon les pays.

Une voie rapide n’est pas toujours une autoroute. Elle peut comporter des intersections, des feux de circulation ou des accès directs, et les usagers autorisés, limitations de vitesse et règles particulières dépendent de la signalisation et de la réglementation locales.

Voie rapide
How can you recognise an expressway?

An expressway may be identified by a special road sign or by its road classification. It often has multiple lanes, limited access and junctions designed for faster traffic, but its exact appearance differs between countries.

Is an expressway the same as a motorway?

No. A motorway normally has full access control and stricter design and traffic rules. An expressway may have partial access control, ordinary intersections, traffic lights or direct entrances. The legal distinction varies between countries.

Is an expressway always divided?

Not necessarily. Many expressways have separate carriageways for opposing traffic, but some countries also classify undivided roads as expressways. Drivers should rely on local signs and road rules rather than the road’s appearance alone.

Who may use an expressway?

Expressways are generally intended for motorised traffic. Pedestrians, cyclists, animals, mopeds and slow vehicles may be restricted or prohibited, but the permitted road users depend on local law and traffic signs.

What is the speed limit on an expressway?

There is no universal expressway speed limit. The applicable limit depends on the country, road design, location, vehicle category and posted signs. An expressway sign does not always impose a particular speed by itself.

Can an expressway have intersections or traffic lights?

Yes. Unlike a motorway, an expressway may have level intersections, roundabouts, pedestrian crossings or traffic lights. Drivers must therefore remain prepared for crossing traffic and changes in priority.

How should you enter an expressway?

Use an entrance or acceleration lane where one is provided, observe approaching traffic and enter only when there is a safe gap. Where the road has an ordinary intersection, follow the applicable priority signs and local rules.

Which lane should you use on an expressway?

Follow the local keep-left or keep-right rule, lane arrows and traffic signs. Lanes nearer the centre are commonly used for overtaking, but special lane restrictions may apply to heavy vehicles or particular destinations.

Can you stop, park, reverse or make a U-turn?

These actions are often restricted on expressways because of the speed and flow of traffic. Stop or park only where permitted, and never reverse or make a U-turn unless the road design and local rules clearly allow it.

What should you do after a breakdown?

Move the vehicle away from moving traffic when this can be done safely, activate the hazard warning lights and follow the local breakdown procedures. Use a warning triangle or safety vest where required and wait in a protected location away from traffic.

4. Limitation de vitesse

Une limitation de vitesse est la vitesse maximale légale autorisée sur une route, une voie ou dans une zone désignée. Elle peut être fixée par la réglementation générale de la circulation ou indiquée par des panneaux fixes, variables ou temporaires.

Une limitation de vitesse est un maximum, et non une vitesse à atteindre. Les conducteurs doivent rouler plus lentement chaque fois que la circulation, la visibilité, la météo, l’état de la route, les usagers vulnérables ou l’état du véhicule rendent dangereuse la vitesse maximale autorisée.

What is a speed limit?

A speed limit is the maximum legal speed permitted on a road, lane or within a designated area. It does not require drivers to travel at that speed.

How can you recognise a speed limit?

A speed limit is commonly displayed as a number on a regulatory traffic sign. General limits may also apply automatically because of the country, road category, vehicle type or surrounding area, even when no speed-limit sign is present.

Is the speed limit a recommended driving speed?

No. It is the highest speed legally permitted under suitable conditions. Drivers must reduce their speed whenever travelling at the limit would be unsafe.

Can you drive more slowly than the speed limit?

Yes. Drivers should travel more slowly when required by traffic, weather, visibility, road conditions or nearby vulnerable road users. Driving unnecessarily slowly may nevertheless be prohibited when it obstructs normal traffic.

Does the same speed limit apply to every vehicle?

Not always. Lower limits may apply to heavy vehicles, buses, vehicles towing trailers, novice drivers or other vehicle categories. The lowest applicable limit must be respected.

What is a default speed limit?

A default speed limit applies automatically to a particular road type or area when no traffic sign indicates another limit. Examples include general limits for motorways, built-up areas or roads outside built-up areas.

Does a posted speed limit replace the default limit?

Usually, yes. A legally placed speed-limit sign normally introduces another maximum speed, although lower vehicle-specific or special-road limits may continue to apply.

When does a speed-limit sign take effect?

A speed restriction normally begins at the location of the sign. Drivers should reduce their speed before passing the sign so that they are already travelling within the limit when it takes effect.

When does a speed limit end?

A signed limit may end at an intersection, an end-of-limit sign, another speed-limit sign or the beginning or end of a legally defined area. The exact rule differs between countries.

Does an intersection end a speed limit?

This depends on local law. An ordinary speed restriction may end at an intersection in some countries, while a zonal speed limit normally continues across intersections until an end-of-zone sign.

What is a speed zone?

A speed zone is an area in which the displayed maximum speed applies throughout all included roads. The limit normally remains in force until the corresponding end-of-zone sign.

What is a variable speed limit?

A variable speed limit is displayed on an electronic or changeable sign and may be adjusted according to congestion, weather, incidents or roadworks. When activated, it has the same legal importance as another applicable regulatory speed sign.

Can different lanes have different speed limits?

Yes. Signs positioned above individual lanes may impose different limits on those lanes. Drivers must observe the limit applying to the lane they use.

Can a temporary speed limit apply?

Yes. Temporary limits may be introduced near roadworks, collisions, hazards or special events. Drivers must follow the temporary traffic signs and instructions that are legally in force.

May you exceed the speed limit while overtaking?

No. Overtaking does not normally permit a driver to exceed the applicable maximum speed. The manoeuvre must be completed safely while respecting the speed limit.

Do poor conditions change the legal speed limit?

Some countries impose specific lower limits in rain, snow or other conditions. Even where the numerical limit does not change, drivers must reduce their speed sufficiently for the conditions.

5. Piste cyclable

Une piste cyclable est une partie de route ou un itinéraire distinct destiné principalement ou exclusivement aux personnes circulant à vélo. Elle peut être physiquement séparée du trafic motorisé, marquée sur la chaussée ou identifiée par des panneaux de signalisation.

Les pistes cyclables peuvent être à sens unique, à double sens ou partagées avec d’autres usagers. Les usagers autorisés, le sens de circulation, les règles de priorité et l’obligation d’utiliser la piste dépendent de la signalisation et de la réglementation locales.

Piste cyclable
How can you recognise a bike path?

A bike path may be identified by a bicycle traffic sign, bicycle symbols, coloured surfacing or road markings. It may run beside the carriageway or follow a completely separate route.

Is a bike path the same as a bike lane?

Not always. A bike lane is normally marked directly on or beside the carriageway, while a bike path may be physically separated from motor traffic. The terminology and legal distinction vary between countries.

Must cyclists use a bike path?

This depends on local law and the signs displayed. Some bike paths are mandatory, while others are optional. Cyclists may also be permitted to leave a path to turn, overtake or avoid an obstruction.

Can a bike path carry traffic in both directions?

Yes. Some bike paths are two-way, but others may be used only in the direction indicated by signs, markings or their position beside the road. Cyclists should not assume that every path permits travel in both directions.

May pedestrians use a bike path?

Pedestrians may use a bike path where it is designated as a shared-use path or where local law permits it. On a cycle-only path, pedestrians may be prohibited or permitted only when no suitable pedestrian facility is available.

May mopeds or speed pedelecs use a bike path?

This depends on the country, vehicle category, road speed and traffic signs. Some bike paths permit or require certain mopeds or speed pedelecs, while others are reserved exclusively for ordinary bicycles.

May motor vehicles use a bike path?

Normally not. Motor vehicles may cross a bike path to enter another road or property where this is permitted, but they must follow the applicable priority rules and must not endanger path users.

Who has priority where a vehicle crosses a bike path?

Priority depends on the road layout, signs, signals and local law. Drivers crossing a continuous bike path commonly have to give way to its users, but cyclists approaching a separate cycle crossing may not automatically have priority before entering it.

Does a cyclist always have priority at a cycle crossing?

No. A marked cycle crossing does not universally give an approaching cyclist priority. Cyclists should enter cautiously and observe approaching traffic unless signs, signals or local rules clearly give them priority.

Is there a speed limit on a bike path?

Some countries or local authorities impose specific limits, particularly on shared paths. Even without a posted limit, cyclists must travel at a safe and considerate speed for the width, visibility and number of other users.

May you stop or park on a bike path?

Normally not. Stopping or parking on a bike path can force cyclists into motor traffic and may be expressly prohibited by law.

What should cyclists do when passing pedestrians?

Reduce speed, give a clear warning where appropriate and leave sufficient space. Pedestrians may change direction unexpectedly, especially on a shared path.

What should cyclists do when a bike path is blocked?

Slow down and check surrounding traffic before leaving the path. Avoid the obstruction safely and return to the bike path when permitted and practical.

Can cyclists ride side by side on a bike path?

This depends on local law and the available width. Even where riding side by side is permitted, cyclists must not block, endanger or unnecessarily hinder other path users.

What is the difference between a bike path and a shared-use path?

A bike path is intended primarily or exclusively for cycling. A shared-use path is legally intended for cyclists together with pedestrians or other indicated road users, who must use the space considerately.

6. Pente

Une pente est une section de route qui monte ou descend de manière notable. Une forte pente peut affecter la vitesse du véhicule, la distance de freinage, l’adhérence, la visibilité et la capacité des véhicules lourds ou peu puissants à maintenir une vitesse régulière.

Des panneaux d’avertissement peuvent signaler une forte montée ou une descente dangereuse et indiquer la déclivité en pourcentage. Les conducteurs doivent adapter leur vitesse à l’avance, choisir un rapport approprié et rester prêts à rencontrer des véhicules lents, des virages et des changements d’état de la chaussée.

What is a road slope?

A road slope is a section of road that rises or descends over a particular distance. It may also be called a gradient, incline or decline.

How can you recognise a steep slope?

A steep slope may be indicated by a warning sign showing an ascending or descending road. The sign may also display the gradient as a percentage.

What does a gradient of 10% mean?

A gradient of 10% means that the road rises or falls approximately 10 metres for every 100 metres travelled horizontally. It does not mean that the road is inclined at 10 degrees.

What is the difference between an ascent and a descent?

An ascent rises in the direction of travel, while a descent falls in the direction of travel. The same section of road is therefore an ascent in one direction and a descent in the other.

Does a slope warning sign impose a speed limit?

Not normally. It warns of a hazard rather than setting a numerical limit. Drivers must still respect the applicable speed limit and reduce their speed further when necessary.

How should you approach a steep descent?

Reduce speed before the descent, select a suitable gear and maintain a safe following distance. Avoid allowing the vehicle to gain excessive speed.

Which gear should you use when descending?

Use a gear that provides sufficient engine braking and helps keep the vehicle at a controlled speed. The appropriate gear depends on the vehicle, gradient and road conditions.

Should you coast downhill in neutral?

No. Coasting reduces engine braking and may make it harder to control the vehicle’s speed. Keep the transmission engaged while descending.

Why should you avoid continuous heavy braking?

Continuous braking on a long descent can cause the brakes to become excessively hot and lose effectiveness. Select a suitable gear, control speed early and use the brakes progressively when needed.

What is brake fade?

Brake fade is a reduction in braking performance caused by excessive heat. It can occur when the brakes are used continuously during a long or steep descent.

How should you drive uphill?

Select a suitable gear before the engine begins to struggle and maintain a steady speed where possible. Be prepared for heavy or low-powered vehicles travelling slowly ahead.

May a vehicle lose speed on a steep ascent?

Yes. Heavy vehicles, vehicles towing trailers and low-powered vehicles may slow considerably. Other drivers should maintain a safe distance and avoid impatient manoeuvres.

May you overtake near the top of a slope?

Do not overtake when the crest prevents you from seeing far enough ahead. Overtaking near a hilltop may also be expressly prohibited by local law, signs or road markings.

Why is visibility limited near the crest of a slope?

The road surface itself may hide approaching traffic, stopped vehicles, pedestrians or other hazards beyond the crest.

Who has priority on a narrow slope?

Some countries give priority to uphill traffic, while others rely on signs or ordinary obstruction rules. Drivers must follow local law and cooperate when passing is difficult.

How should you meet another vehicle on a narrow slope?

Reduce speed and use a passing place where available. The driver who can reverse or move aside more safely should cooperate, subject to any applicable priority signs or local rules.

How do rain, snow or ice affect a slope?

They reduce traction and make acceleration, braking and steering more difficult. Increase the following distance, use smooth controls and reduce speed before entering the slope.

Why are cyclists vulnerable on slopes?

Cyclists may travel slowly and move less steadily when climbing, while they may reach high speeds when descending. Drivers should leave sufficient space and avoid overtaking without a clear view.

How should you park on a slope?

Use the parking brake, select the appropriate gear or parking position and follow local rules concerning wheel position. Make sure the vehicle cannot roll into traffic.

Can a slope affect towing?

Yes. A trailer increases the load on the engine and brakes and may affect stability. Drivers should use a suitable gear, maintain additional distance and avoid excessive speed.

7. Arrêt de bus

Un arrêt de bus est un endroit désigné où les autobus s’arrêtent pour permettre aux passagers de monter ou descendre. Il peut être identifié par un panneau, un abri, un quai surélevé, un marquage routier ou une autre infrastructure de transport public et peut se trouver au bord de la route ou dans une zone d’arrêt spécialement aménagée.

Les conducteurs qui approchent d’un arrêt de bus doivent surveiller attentivement les autobus, les piétons et les passagers qui traversent ou pénètrent sur la chaussée. Des restrictions d’arrêt ou de stationnement peuvent s’appliquer autour des arrêts afin de maintenir la zone accessible et visible.

Arrêt de bus
What is a bus stop?

A bus stop is a designated location where buses stop so that passengers can board or leave the vehicle.

What should you watch for near a bus stop?

Watch for buses entering or leaving the stop, passengers near the roadway and pedestrians who may cross the road.

Can you park at a bus stop?

Parking or stopping at or near a bus stop is often restricted or prohibited so that buses can reach the stop safely. The exact restrictions depend on local traffic rules.

8. Rond-point

Un rond-point est un aménagement circulaire dans lequel la circulation tourne autour d’un îlot central dans une direction déterminée. Les véhicules entrent et sortent par les routes raccordées, et la signalisation ou les règles locales déterminent la priorité.

Les conducteurs doivent réduire leur vitesse, choisir une voie appropriée, observer tous les usagers et signaler comme requis lors de la sortie. Le sens de circulation, la priorité à l’entrée, l’utilisation des voies et les règles concernant cyclistes et piétons dépendent de la signalisation et de la réglementation locales.

What is a roundabout?

A roundabout is a circular road arrangement where traffic travels in one direction around a central island before leaving through the chosen exit.

How can you recognise a roundabout?

A roundabout is normally identified by a circular-direction sign, a central island and entry roads controlled by signs, markings or local priority rules.

Which direction does traffic travel around a roundabout?

The direction depends on the country’s driving side. Traffic normally travels anticlockwise in right-hand-traffic countries and clockwise in left-hand-traffic countries.

Who has priority at a roundabout?

Priority differs between countries and roundabout designs. Entering traffic commonly gives way to traffic already circulating, but drivers must always follow the actual priority signs and signals.

Must you stop before entering a roundabout?

Not always. Stop when required by a stop sign, traffic light or approaching priority traffic. Otherwise, reduce speed and enter only when there is a safe gap.

Does a roundabout always have a give-way sign?

No. The sign arrangement depends on local law. Some circular intersections use ordinary priority rules or traffic lights instead.

How should you approach a roundabout?

Reduce speed, observe the signs and markings, choose the appropriate lane and check for pedestrians, cyclists and circulating traffic.

Which lane should you choose?

Follow the lane arrows and destination signs. As a general guide, use the lane appropriate for your exit, but exact lane-selection rules differ between countries and roundabout layouts.

May you use an inner lane?

Yes, where the road layout and local rules permit it. Before leaving, change lanes safely and give way to road users already travelling in the lane you wish to enter.

Do you need to signal when entering?

This depends on local law. Some countries require a signal for particular exits, while others require no signal when entering.

Do you need to signal when leaving?

Usually, yes. Signal in the direction of the exit early enough to inform other road users, but not so early that your intention becomes misleading.

Does signalling give you priority?

No. A direction indicator communicates your intention but does not permit you to force another road user to brake or change direction.

May you change lanes on a roundabout?

Only when the lane markings permit it and the manoeuvre can be completed safely. Check mirrors and blind spots, signal where required and give way to traffic already in the target lane.

What should you do if you miss your exit?

Continue around the roundabout and approach the exit again. Do not stop, reverse or cut suddenly across another lane.

May you drive over the central island?

Normally not. Some small roundabouts have a mountable central section intended only for vehicles that cannot otherwise negotiate the road safely.

Do cyclists have priority at a roundabout?

Priority depends on whether cyclists use the carriageway, a continuing bike path or a separate cycle crossing. Drivers and cyclists must follow the signs, markings and local priority rules.

What should drivers check before leaving?

Check mirrors and blind spots for cyclists, mopeds, motorcycles and vehicles beside you. Also check for pedestrians crossing the exit road.

Do pedestrians have priority at roundabout exits?

Pedestrian priority depends on crossings and local law. Drivers should approach exits slowly and be prepared to yield to pedestrians crossing or about to cross.

Does a roundabout have a special speed limit?

Not universally. The posted or general road limit applies, but drivers must travel slowly enough to negotiate the roundabout safely.

May you overtake on a roundabout?

Passing another vehicle may be permitted on a multilane roundabout, but drivers must remain within their lane and avoid unsafe lane changes. Local overtaking restrictions may apply.

May you stop or park on a roundabout?

Follow local signs and parking rules. Stopping or parking on the circulating roadway is commonly prohibited or unsafe because it obstructs traffic and reduces visibility.

Is every circular intersection a roundabout?

No. A circular junction may be governed by traffic lights, ordinary priority rules or another road design. Its legal status depends on its signs and local definition.

9. Passage à niveau

Un passage à niveau est un endroit où une route ou un chemin croise des voies ferrées au même niveau. Il peut être protégé par des barrières, des feux d’avertissement, des sonneries, des panneaux de signalisation ou une combinaison de ces dispositifs.

Les usagers doivent approcher avec prudence et ne jamais s’engager lorsqu’un train approche, que les signaux d’avertissement sont actifs ou que la sortie est bloquée. Ils doivent traverser sans délai et ne jamais s’arrêter, attendre ou se retrouver immobilisés sur les voies.

Passage à niveau
What is a railway crossing?

A railway crossing is a place where a road or path crosses railway tracks at the same level.

What is another name for a railway crossing?

It may also be called a level crossing or, particularly in North America, a railroad crossing.

How can you recognise a railway crossing?

It may be indicated by warning signs, crossbuck signs, barriers, flashing lights, bells or road markings. The design differs between countries.

What is the difference between a crossing with and without barriers?

A protected crossing uses full or partial barriers to block road traffic when a train approaches. A crossing without barriers relies on signs, lights, bells or the road user’s own observation.

Must you always stop at a railway crossing?

Not necessarily. You must stop when required by lights, barriers, signs, an approaching train or an authorised person. At an unprotected crossing, slow down and proceed only after checking that no train is approaching.

What do flashing red lights mean?

Flashing red lights mean stop and do not enter the crossing. Remain stopped until the signal permits you to continue.

May you cross while a barrier is moving?

No. Do not enter while a barrier is lowering, rising or closed. Wait until the crossing is fully open and all prohibiting signals have stopped.

May you drive around a closed barrier?

No. Never drive, cycle or walk around or underneath a closed or moving barrier.

What does a warning bell mean?

A warning bell or audible signal normally means that the crossing is closing or that a train is approaching. Do not enter the crossing while it is sounding.

What does a flashing white light mean?

In some countries, a flashing white light indicates that the crossing equipment is operating and road users may pass when the route is clear. Its exact meaning depends on local law.

What should you do at a crossing without lights or barriers?

Reduce speed, look and listen carefully in both directions and cross only after making sure that no train or other rail vehicle is approaching.

May you cross immediately after a train has passed?

Not automatically. Another train may approach on a second track. Wait until all warning signals stop and the crossing is fully open.

What if traffic ahead is blocking the exit?

Do not enter the crossing unless there is enough room beyond the tracks for your entire vehicle. Never rely on traffic moving before a train arrives.

May you wait on the tracks?

No. Railway tracks must always remain clear. Do not stop because of congestion, traffic lights or another obstruction beyond the crossing.

May you overtake at a railway crossing?

Overtaking is often prohibited or restricted because another vehicle can obstruct the view of an approaching train or warning signal. Follow local signs and overtaking rules.

May you stop or park on a railway crossing?

No. Stopping or parking on the tracks creates an immediate and potentially fatal danger.

Do the crossing signals apply to pedestrians and cyclists?

Yes. Pedestrians and cyclists must obey barriers, lights, bells and authorised personnel in the same way as other road users.

Should cyclists ride across the tracks at an angle?

Where possible, cross the rails at an angle close to 90 degrees. Rails can trap a bicycle wheel, especially when they are wet or cross the road diagonally.

What should drivers of long vehicles check?

Make sure the entire vehicle and any trailer can clear the crossing without stopping. Consider the available space, road gradient, turning room and traffic beyond the tracks.

What should drivers of high vehicles check?

Observe all height restrictions and warning signs. Electrified railway lines may have overhead equipment that can be struck by an excessively high vehicle or load.

What should you do if the signals appear defective?

Treat the crossing with extreme caution. Do not assume that no train is approaching merely because the lights or barriers are not operating.

What should you do if your vehicle becomes stuck on the tracks?

Evacuate everyone immediately, move well away from the railway and contact the emergency services or railway operator. Do not remain in the vehicle or return for belongings.

Is a railway crossing the same as tram tracks in the road?

Not always. A railway crossing normally crosses tracks that are separate from the carriageway, while tram or street-running railway tracks may form part of the road itself.

10. Circulation à contresens

La circulation à contresens se produit lorsqu’un conducteur roule dans le sens opposé au sens de circulation légalement autorisé. Cela peut arriver sur une route à sens unique, une route à chaussées séparées, une entrée ou sortie d’autoroute ou une autre section réservée à une seule direction.

La circulation à contresens crée un risque extrême de collision frontale. Les conducteurs doivent respecter les panneaux directionnels, les sens interdits, les flèches de voie et les marquages routiers. Toute personne s’engageant accidentellement à contresens doit ralentir, avertir les autres usagers, s’arrêter à l’endroit le plus sûr disponible et contacter les services d’urgence.

Circulation à contresens
What is wrong-way driving?

Wrong-way driving means travelling against the legally permitted direction of traffic.

Where can wrong-way driving occur?

It can occur on one-way streets, divided roads, motorways, slip roads, tunnels, car parks and temporary traffic arrangements.

Why is wrong-way driving especially dangerous?

Other drivers do not expect approaching traffic in their lane, and the combined speeds can make a head-on collision extremely severe.

How can you recognise a prohibited direction?

Look for no-entry signs, one-way signs, mandatory-direction signs, lane arrows and road markings. Motorway exits may also have repeated signs or warning systems facing the wrong direction.

Is wrong-way driving the same as entering a no-entry road?

Entering past a no-entry sign can cause wrong-way driving, but the term also covers turning around on a divided road or using the wrong carriageway without passing such a sign.

Is driving against a one-way street always prohibited?

Normally, yes. However, signs may expressly permit certain road users, such as cyclists or public transport, to travel in the opposite direction.

Is authorised contraflow traffic wrong-way driving?

No. A cyclist, bus or other road user travelling in an expressly authorised contraflow lane or direction is using the road legally.

Can roadworks temporarily change the normal direction?

Yes. Temporary signs, barriers, lane signals and markings may redirect traffic onto another lane or carriageway. Follow the temporary arrangement rather than the usual road layout.

What should you do when you see a wrong-way driver?

Reduce speed immediately, keep as far as safely possible towards the outer edge of your carriageway and avoid sudden lane changes. Warn the police or emergency services as soon as this can be done safely.

Should you attempt to stop the wrong-way driver?

No. Do not block, chase or turn after the vehicle. Protect yourself and allow trained emergency services to intervene.

Should you flash your headlights?

A brief warning may help the driver recognise the error, but avoid prolonged or aggressive signalling that could cause panic or an unpredictable manoeuvre.

Should you sound the horn?

Use the horn only when reasonably necessary to warn of immediate danger. Your first priority is to reduce speed and create as much safe space as possible.

Should you stop in a live traffic lane?

Normally not. Sudden stopping may cause a rear-end collision. Slow down and move towards a safe shoulder, refuge or other protected location where possible.

What should you do after receiving a wrong-way-driver warning?

Reduce speed, stop overtaking, increase your following distance and remain in the lane or position recommended by the local authorities or warning system.

Should you continue using the overtaking lane?

Avoid unnecessary use of lanes nearest opposing or central traffic when a wrong-way driver has been reported. Follow local emergency guidance and electronic signs.

What should you do if you are driving in the wrong direction?

Slow down immediately, activate the hazard warning lights and use dipped headlights where required. Move to the safest available edge or shoulder and stop.

Should you accelerate to reach the next exit?

No. Increasing speed greatly increases the collision risk. Stop safely and wait for instructions from the police.

Should you make a U-turn across traffic?

No. Do not turn across live lanes, cross a central reservation or attempt to correct the mistake through another dangerous manoeuvre.

Should you reverse back to the entrance?

No. Reversing against traffic or along a motorway slip road creates additional danger. Stop safely and contact the emergency services.

Should you leave the vehicle after stopping?

This depends on the location and immediate danger. Remain protected from moving traffic and follow instructions from the emergency services. Do not stand in a live lane.

How should you contact the emergency services?

Stop safely before using a handheld phone. A passenger may call while the vehicle is moving when local law permits and this can be done without distracting the driver.

What information should you report?

Report the road name or number, direction, nearby exit or landmark, vehicle description and the wrong-way driver’s approximate location and direction.

What commonly causes wrong-way driving?

Possible causes include confusion at junctions, poor visibility, unfamiliar roads, impairment, navigation errors, turning around illegally or deliberately ignoring traffic signs.

How can drivers prevent entering the wrong direction?

Slow down at unfamiliar junctions, read signs before turning, verify the road layout and do not rely exclusively on navigation instructions.

Does a navigation system override traffic signs?

No. Traffic signs, signals, markings and instructions from authorised persons always take precedence over navigation guidance.

11. Feux de circulation

Les feux de circulation utilisent des lumières colorées, des flèches ou des symboles pour indiquer quand les usagers peuvent avancer, doivent se préparer à s’arrêter ou doivent rester arrêtés. Des signaux distincts peuvent s’appliquer à certaines directions, voies, aux piétons, cyclistes ou véhicules de transport public.

Un feu vert autorise le mouvement uniquement lorsque le passage est libre et que la manœuvre est par ailleurs légale. Les usagers doivent toujours respecter les règles de priorité, interdictions de tourner, marquages de voie et instructions des agents habilités.

Feux de circulation
What are traffic lights?

Traffic lights are signals that use coloured lights, arrows or road-user symbols to regulate traffic movements.

What does a red traffic light mean?

A red light requires road users to stop before the stop line or signal and remain stopped until movement is permitted.

What does a steady amber light mean?

A steady amber light normally requires drivers to stop unless they are already too close to stop safely. It warns that the signal is changing to red.

What does a green traffic light mean?

A green light permits road users to pass the signal, but only when the route is clear and the intended movement is otherwise legal.

Does green mean that you have priority over everyone?

No. You may still have to give way to pedestrians, cyclists, oncoming traffic or other road users when turning or following a conditional arrow.

May you enter a blocked intersection on green?

No. Do not enter when congestion is likely to leave you stopped inside the intersection and obstructing crossing traffic.

Where should you stop at a red light?

Stop before the stop line. When no stop line is provided, stop before the traffic light or at another legally prescribed position.

May you cross the stop line and then stop?

No. The required stop must normally be completed before the stop line. Do not stop on a pedestrian or cycle crossing.

What if the light changes to amber while you are approaching?

Stop when this can be done safely. Continue only when you are already too close to stop without creating danger.

Should you accelerate to pass an amber light?

No. Do not accelerate to avoid stopping. Maintain control and stop unless doing so safely is no longer possible.

What do arrow-shaped traffic lights mean?

They have the same general meaning as circular lights, but the prohibition or permission applies only to the direction shown by the arrow.

What does a green arrow displayed with a red light mean?

It may permit travel in the indicated direction while other movements remain prohibited. Drivers may still have to give way to conflicting traffic and pedestrians.

Does a green arrow override a no-turn sign?

Not universally. Drivers must follow the complete local sign arrangement. A traffic signal does not necessarily cancel a separate regulatory prohibition.

May you turn right on red?

Only where local law or a specific sign or signal expressly permits it. There is no universal right to turn on red.

What does a flashing amber light mean?

It warns of a potential hazard and normally allows cautious passage. The ordinary priority arrangement remains applicable.

What should you do when the normal lights are flashing amber?

Reduce speed, observe the intersection carefully and follow the applicable priority signs or default priority rules.

What does a flashing red light mean?

Its meaning depends on local law. At railway crossings and some movable bridges, flashing red lights normally require road users to stop.

What do lane-control signals mean?

A red cross normally closes the lane, a green downward arrow opens it and an amber diagonal arrow instructs drivers to leave the lane in the indicated direction.

May you continue beneath a red lane-control cross?

No. Move out of the lane safely before reaching the red cross unless an authorised person or emergency rule directs otherwise.

What does an amber diagonal lane arrow mean?

It warns that the lane is closing or unavailable ahead. Drivers must move into the adjacent lane indicated by the arrow when safe.

Can separate lights apply to cyclists?

Yes. A signal displaying a bicycle symbol applies to the road users legally covered by that signal rather than to general motor traffic.

Can separate lights apply to pedestrians?

Yes. Pedestrian lights normally use red and green human figures to indicate whether pedestrians may begin crossing.

What does a flashing green pedestrian light mean?

It normally warns that the crossing period is about to end. Pedestrians who have not started should wait for the next green signal.

What if the pedestrian signal changes while someone is crossing?

A person who entered lawfully should continue without unnecessary delay. Turning drivers must allow the crossing to be completed safely.

Can buses and trams have separate traffic lights?

Yes. Public-transport signals may use bars, circles, triangles or other symbols that apply only to authorised service vehicles.

Do functioning traffic lights override priority signs?

They commonly replace the priority arrangement at that location. Priority signs may apply again when the normal signals are inactive or flashing.

Do instructions from a police officer override traffic lights?

Yes. Instructions from an authorised traffic controller normally take precedence over lights, signs, markings and ordinary rules.

What should you do when the lights are not working?

Reduce speed and follow the priority signs, temporary signals, authorised personnel or default priority rules that apply.

May you clear an intersection after the light turns red?

Yes, when you entered lawfully and must leave the intersection. Complete the movement cautiously without endangering other road users.

Does a green light impose a minimum speed?

No. Drivers may proceed but must continue at a safe and legal speed.

May you use a handheld phone while waiting at red?

This depends on local law. In many countries, a driver temporarily stopped in traffic is still considered to be driving and may not use a handheld device.

12. Miroir routier

Un miroir routier est un miroir convexe installé près d’un carrefour, d’une sortie, d’un virage ou d’un autre endroit offrant une visibilité limitée. Sa surface courbe offre une vue plus large des usagers approchant qu’un miroir plat ordinaire.

Un miroir routier n’est qu’une aide à la visibilité. Il peut déformer la distance, la vitesse et la direction et être affecté par l’obscurité, la météo, la saleté ou les dommages. Les conducteurs doivent continuer à observer directement la route, respecter toutes les règles de priorité et ne s’engager que lorsque cela est sûr.

Miroir routier
What is a traffic mirror?

A traffic mirror is a convex roadside mirror that helps road users see around an obstruction or into a road with limited visibility.

Where are traffic mirrors commonly installed?

They may be placed near intersections, narrow roads, bends, car-park exits, private driveways, tunnels or other locations where buildings, vegetation or road geometry obstruct the view.

Why is the mirror curved?

A convex surface provides a wider field of view than a flat mirror, allowing more of the approaching road to be seen.

Does a traffic mirror show an exact image?

No. The reflected image is distorted, and objects normally appear smaller and farther away than they really are.

Can you accurately judge speed in a traffic mirror?

Not reliably. The curved image makes it difficult to estimate how fast another road user is approaching.

Can you accurately judge distance in the mirror?

No. Distance can appear greater than it really is, so an approaching vehicle may reach the intersection sooner than expected.

Can the mirror create a blind area?

Yes. Its position and viewing angle may leave parts of the road outside the reflected image. Small cyclists, motorcycles or pedestrians may also be difficult to notice.

Does a traffic mirror give you priority?

No. It does not change priority. Drivers must continue to follow stop signs, give-way signs, traffic lights and the ordinary priority rules.

Does seeing an empty mirror mean the road is clear?

No. Another road user may be outside the reflected area, hidden by glare or too small to notice. Always check the road directly before proceeding.

Must you still stop at a stop sign?

Yes. The mirror does not replace the mandatory complete stop. Stop at the prescribed position, then use direct observation and the mirror as additional information.

Must you still give way?

Yes. You may proceed only when traffic with priority can continue without being forced to brake, stop or change direction.

How should you use a traffic mirror?

Approach slowly, stop when required and scan the mirror for movement. Then look directly in both directions and continue only after confirming that the road is clear.

Should you look only at the mirror?

No. Alternate between the mirror and direct observation. The mirror should supplement rather than replace normal checks.

Can rain affect a traffic mirror?

Yes. Rain, water droplets and spray may blur or partially obscure the reflected image.

Can frost or condensation affect it?

Yes. Dew, condensation, frost, ice or snow may make the mirror difficult or impossible to use.

Can sunlight cause problems?

Yes. Sunlight may create glare or reflections that hide approaching road users.

Can headlights be misleading at night?

Yes. Reflected headlights may make it difficult to determine the exact direction, distance or speed of an approaching vehicle.

Can the mirror move out of position?

Yes. Wind, impacts, vandalism, vibration or temperature changes may alter its orientation and make the reflected view inaccurate.

What if the mirror is dirty or damaged?

Do not rely on it. Proceed with additional caution and report the defect to the responsible road authority or property owner.

Does a traffic mirror impose a speed limit?

No. The applicable road or posted speed limit remains in force, but restricted visibility normally requires a lower approach speed.

Does it require drivers to sound the horn?

No. Use the horn only where local law permits it and a warning is reasonably necessary to prevent danger.

Can pedestrians and cyclists use the mirror?

Yes. It may help them observe approaching traffic, but they must also look directly and follow the applicable crossing and priority rules.

Can a private individual install a traffic mirror?

A mirror may generally be installed on private property with the owner’s permission, subject to local rules. Installing one on, above or beside a public road normally requires permission from the road authority.

Should a mirror replace better road design?

No. Removing vegetation, relocating parking, improving the intersection layout or changing traffic circulation may provide a safer and more reliable solution.

13. Stationnement

Le stationnement consiste à laisser un véhicule immobile à un endroit pendant un certain temps, plutôt que de s’arrêter brièvement en raison de la circulation ou d’une nécessité immédiate. De nombreux pays distinguent le stationnement d’un arrêt bref effectué pour faire monter ou descendre des passagers ou pour charger ou décharger des marchandises, même si la définition juridique précise varie.

Le stationnement peut être autorisé, limité, réservé, soumis à une durée maximale ou interdit par des panneaux, marquages, zones de stationnement et règlements locaux. Les conducteurs doivent stationner sans créer de danger ni de gêne inutile et respecter toute condition concernant le paiement, les permis, les catégories de véhicules ou la durée maximale.

Stationnement
What is the difference between parking and stopping?

Parking generally means leaving a vehicle stationary for longer than a brief stop required for passengers, loading or unloading. A vehicle stopped because of traffic lights, congestion, an emergency or another traffic condition is normally not considered parked. The precise legal definitions vary between countries.

How can you tell where parking is allowed?

Look for parking signs, prohibition signs, road markings and parking-zone signs. Local rules may also permit parking along certain roads even when individual parking spaces are not marked.

Can you park anywhere if there is no sign prohibiting parking?

No. General traffic rules can prohibit parking even when no specific prohibition sign is present. Common examples include locations where a parked vehicle would obstruct visibility, crossings, intersections, cycle facilities or the movement of other traffic.

Can you park on a pavement or sidewalk?

Parking on a pavement or sidewalk is prohibited or restricted in many countries unless signs or markings specifically allow it. Vehicles must not force pedestrians into the roadway or block an accessible pedestrian route.

Can you park near a pedestrian crossing?

Parking on or close to a pedestrian crossing is generally restricted because a vehicle can hide pedestrians from approaching drivers. The required clearance distance varies between countries.

Can you park close to an intersection?

Many countries prohibit parking within a specified distance of an intersection because parked vehicles can reduce visibility and obstruct turning traffic. Follow the local distance requirements and any signs or markings.

What does a parking sign mean?

A parking sign identifies a place or area where parking is permitted or regulated. Additional signs or panels may specify time limits, payment requirements, vehicle categories, permits or particular parking arrangements.

How does paid parking work?

Where parking is subject to payment, drivers must follow the instructions displayed locally. Payment may be made through a parking meter, ticket machine, mobile application or another authorised system. The permitted duration and charging periods vary by location.

Who may use an accessible parking space?

Spaces marked for people with disabilities are reserved for vehicles displaying or registered with the required disability parking permit. Eligibility, permit display requirements and parking privileges depend on national and local law.

Can you leave a vehicle parked for an unlimited time?

Not necessarily. Local rules may impose a maximum parking duration, even where parking is otherwise permitted. Different limits may apply to abandoned, commercial, heavy or recreational vehicles.

14. Marche arrière

La marche arrière consiste à conduire un véhicule vers l’arrière. Elle est couramment utilisée pour stationner, quitter un espace restreint ou repositionner un véhicule lorsque le mouvement vers l’avant n’est pas pratique.

Avant de reculer, le conducteur doit vérifier les rétroviseurs et angles morts, observer attentivement les alentours du véhicule et s’assurer que l’espace derrière est libre. La marche arrière doit être effectuée lentement et uniquement aussi longtemps que nécessaire, car la visibilité derrière le véhicule est souvent limitée.

Marche arrière
What should you check before reversing?

Check behind and around the vehicle for pedestrians, cyclists, other vehicles and obstacles. Use mirrors and cameras where available, but also look directly because monitoring systems can have blind spots.

Who has priority when a vehicle is reversing?

In many countries, reversing is treated as a manoeuvre and the reversing driver must give way to other road users. The exact legal requirements depend on national traffic rules.

Should you reverse for a long distance?

No. Reversing should normally be limited to the distance necessary to complete the manoeuvre safely. Driving forward generally provides better visibility and vehicle control.

15. Limite d’agglomération

Une limite d’agglomération est la frontière à partir de laquelle une zone bâtie ou urbaine commence ou se termine pour l’application des règles de circulation. Elle est couramment indiquée par un panneau de nom de localité ou d’agglomération et peut marquer le point où certaines règles, telles que les limitations urbaines, règles de stationnement ou autres restrictions, commencent ou cessent de s’appliquer.

Une limite d’agglomération au sens routier ne correspond pas nécessairement exactement à la limite administrative d’une ville ou commune. Sa signification juridique dépend des panneaux et règles de circulation utilisés dans le pays.

What is a city limit?

A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.

Does a city-limit sign always mark a built-up area?

No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.

Does passing a city-limit sign always change the speed limit?

No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.

Is a city limit the same as a municipal boundary?

Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.

What is the difference between a city limit and a built-up area?

A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.

16. Plaque d’immatriculation

Une plaque d’immatriculation, également appelée plaque minéralogique ou plaque de numéro, est une plaque affichant un identifiant unique attribué à un véhicule par l’autorité compétente. Elle permet d’identifier le véhicule à des fins telles que l’immatriculation, le contrôle routier, la fiscalité, l’assurance et le contrôle du stationnement.

L’apparence, le format, l’emplacement et le nombre de plaques exigées varient selon les pays et catégories de véhicules. Les conducteurs doivent veiller à ce que les plaques requises soient correctement fixées, clairement visibles et lisibles et respecter les règles locales en cas de perte, vol, détérioration ou remplacement.

Plaque d’immatriculation
What is a licence plate?

A licence plate is a plate displaying the registration identifier assigned to a vehicle. It allows authorities and other authorised systems to identify the vehicle's registration.

Is a licence plate the same as a registration plate?

Yes. Licence plate, registration plate and number plate are different terms commonly used for the plate displaying a vehicle's official registration number.

Does every vehicle need a licence plate?

Most motor vehicles used on public roads must display one or more registration plates, but requirements differ for motorcycles, trailers, agricultural vehicles and other special vehicle categories.

Do vehicles need both front and rear licence plates?

This depends on the country and vehicle type. Cars commonly require front and rear plates, while motorcycles and certain other vehicles may require only a rear plate.

Must a licence plate remain visible?

Yes. A required registration plate must normally remain clearly visible and readable. It should not be hidden by luggage, dirt, accessories or other objects.

Can you modify a licence plate?

Generally no. Changing the characters, colours, dimensions or appearance of an official plate may make it invalid or illegal. Plates and authorised reproductions must comply with local specifications.

What should you do if a licence plate is lost or stolen?

Follow the local reporting and replacement procedure. Many countries require the loss or theft to be reported to the police or vehicle-registration authority before a replacement plate can be issued.

Can you drive with a damaged licence plate?

A plate must remain legible and compliant with local requirements. If damage prevents it from being read or makes it invalid, it should be replaced according to the local registration procedure.

Can a licence plate be personalised?

Some countries allow motorists to request a personalised registration combination. The available characters, formats and prohibited combinations are determined by the registration authority.

Does a licence plate stay with the vehicle when it is sold?

This varies between countries. In some systems the plate remains with the vehicle, while in others it remains associated with the registered holder and may be retained or returned when the vehicle is sold.

17. Autobus

Un autobus est un véhicule à moteur conçu pour transporter plusieurs passagers, généralement sur route dans le cadre des transports publics, scolaires, privés ou d’un autre service de transport de personnes. Les autobus ont généralement une capacité supérieure aux voitures et peuvent être conçus pour des passagers assis, debout ou les deux.

Des règles particulières peuvent s’appliquer concernant le permis, la capacité, les limitations de vitesse, les ceintures, les voies de bus, les arrêts et l’embarquement des passagers. La classification juridique des autobus et autocars et les règles applicables varient selon les pays ; conducteurs et passagers doivent donc respecter la réglementation locale.

Autobus
What is a bus?

A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.

What is the difference between a bus and a coach?

A bus is commonly designed for frequent passenger boarding and may allow standing passengers, while a coach is generally designed for longer journeys with passengers seated. Exact legal definitions vary between countries.

Do you need a special driving licence to drive a bus?

Yes. Driving a vehicle designed to carry more than a specified number of passengers normally requires a dedicated bus or passenger-vehicle driving licence.

Can passengers stand on a bus?

Only when the vehicle is designed and approved to carry standing passengers. Coaches and other vehicles designed exclusively for seated passengers must not be used beyond their approved passenger configuration.

Must bus passengers wear seat belts?

Where seat belts are provided and local law requires their use, passengers must wear them correctly. Urban buses designed for standing passengers may have seating positions or operating conditions that differ from coaches.

Can buses use bus lanes?

Yes, where permitted. Bus lanes are commonly reserved for public transport buses, although local signs may also allow taxis, bicycles or other specified vehicles to use them.

Do buses always have priority when leaving a bus stop?

No. Some countries require other drivers to give way to buses leaving designated stops, particularly in urban areas, while others apply the normal merging rules.

Should you take extra care near a stopped bus?

Yes. Passengers may be boarding, leaving or crossing the road near the bus. Reduce speed where necessary and watch carefully for pedestrians emerging from behind or in front of the vehicle.

Do buses have special speed limits?

They can. Some countries impose lower maximum speeds on buses than on passenger cars, particularly on high-speed roads. Different limits may apply to buses and coaches.

Can a bus use a motorway?

Yes, normally. Buses that satisfy the applicable construction and access requirements may use motorways, but they must obey any vehicle-specific speed limits, lane restrictions and other local rules.

18. Police

La police regroupe les autorités publiques chargées de faire respecter les lois, maintenir la sécurité publique et gérer les situations pouvant affecter la circulation. Sur la route, les agents peuvent contrôler les véhicules, faire respecter les règles, enquêter sur les collisions, diriger la circulation et intervenir en urgence.

Les usagers doivent respecter les instructions légales données par la police ou d’autres personnes habilitées à contrôler la circulation. Selon la loi locale, les instructions de la police peuvent temporairement primer sur les feux de circulation, panneaux ou organisation habituelle.

What is the role of police in road traffic?

Police help enforce traffic laws, manage traffic, investigate collisions and respond to dangerous situations. They may also carry out roadside checks and direct road users.

Must you obey a police officer directing traffic?

Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.

What should you do if police signal you to stop?

Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.

Can police direct you through a red traffic light?

Yes, where authorised by local law. A police officer controlling traffic may instruct road users to proceed even when a traffic light or sign would normally require them to stop.

Can police check your driving documents?

Yes. Police may require drivers to provide documents such as a driving licence, vehicle registration, identification or proof of insurance according to local law.

Can police carry out alcohol or drug checks?

Yes. Traffic police may conduct legally authorised alcohol and drug checks using procedures such as breath, saliva or other approved tests.

Can police temporarily close a road?

Yes. Roads or lanes may be temporarily closed or traffic diverted because of collisions, emergencies, investigations, public events or other safety concerns.

What should you do near police controlling an accident scene?

Reduce speed, remain alert and follow all directions. Do not enter a closed area or interfere with emergency personnel, and leave sufficient space for emergency vehicles.

What should you do when a police vehicle approaches with emergency signals?

Follow the local rules for priority vehicles. Drivers generally have to make sufficient space, give way and stop where necessary so that the emergency vehicle can pass safely.

Can police order a parked vehicle to be moved?

Yes, where local law permits it. Police or another authorised authority may require a vehicle to be moved when it obstructs traffic, creates danger or must be removed for operational reasons.

19. Ambulance

Une ambulance est un véhicule équipé et utilisé pour fournir une assistance médicale d’urgence ou transporter des patients vers ou entre des établissements de santé. Elle peut transporter du matériel médical et du personnel formé pouvant prodiguer des soins pendant le transport.

Lors d’une intervention urgente, une ambulance peut utiliser des feux d’avertissement et une sirène et bénéficier d’une priorité spéciale ou d’exemptions à certaines règles. Les autres usagers doivent respecter les règles locales applicables aux véhicules d’urgence, laisser suffisamment d’espace et ne pas gêner leur passage.

Ambulance
What is an ambulance?

An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.

When does an ambulance have priority?

This depends on the local traffic rules and warning signals being used. Ambulances responding to emergencies commonly use flashing lights and a siren to indicate that other road users must make way.

What should you do when an ambulance approaches?

Remain calm and make sufficient space for it to pass. Slow down or stop where necessary, but avoid sudden or dangerous manoeuvres.

Should you stop immediately when you hear an ambulance siren?

Not necessarily in your exact position. Move or stop in a way that creates a safe passage without blocking an intersection, pedestrian crossing or another part of the road needed by the ambulance.

Can an ambulance pass a red traffic light?

Emergency vehicles may be allowed to pass a red light during an urgent response under special legal conditions. The precise rules differ between countries, and the ambulance driver must still take appropriate precautions.

Can an ambulance exceed the speed limit?

Many countries permit emergency vehicles to depart from certain normal speed rules during an urgent mission, subject to safety requirements and national legislation.

Can an ambulance drive through a traffic queue?

Yes, when responding to an emergency and legally permitted to do so. Other road users should create space and keep emergency corridors or access routes clear where required.

Can you follow an ambulance through traffic?

You should not use the passage created for an ambulance as a way to bypass congestion. Maintain a safe distance and continue to obey the normal traffic rules.

Do ambulances always use their sirens?

No. The use of warning lights and sirens depends on the urgency of the mission and local regulations. An ambulance transporting a patient does not necessarily need to use emergency signals throughout the journey.

What should you do near a stationary ambulance?

Reduce speed and remain alert. Medical personnel, patients or other emergency workers may be entering the road, and the ambulance may need to move unexpectedly.

20. Norme européenne d’émissions

Une norme européenne d’émissions, couramment appelée norme Euro, est une classification européenne des véhicules fondée sur les limites de polluants émis par les véhicules et leurs moteurs. Les normes successives, telles qu’Euro 4, Euro 5 et Euro 6, ont introduit des exigences de plus en plus strictes pour des polluants tels que les oxydes d’azote, les particules, le monoxyde de carbone et les hydrocarbures.

La norme Euro d’un véhicule est déterminée dans le cadre de son homologation de type et dépend notamment de la catégorie, du carburant et de la législation sur les émissions applicable lors de l’homologation. Les normes Euro peuvent également être utilisées pour déterminer l’accès aux zones de basses émissions, mais les règles locales varient selon les pays et villes.

Norme européenne d’émissions
What is a European emission standard?

A European emission standard, or Euro standard, classifies vehicles according to the emissions requirements they had to satisfy when approved for use in the European market.

What do Euro 4, Euro 5 and Euro 6 mean?

They are successive generations of European emission requirements. In general, a higher Euro number represents a newer and stricter emissions standard, although the exact limits differ according to vehicle and fuel type.

Which pollutants do Euro standards regulate?

Depending on the vehicle and standard, limits apply to pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons. Newer standards also regulate additional environmental aspects.

Is the Euro standard the same as a vehicle's CO2 emissions?

No. Euro standards primarily regulate harmful air pollutants from vehicles. Carbon-dioxide emissions and fuel or energy consumption are subject to separate measurements and regulatory requirements.

How can you find a vehicle's Euro standard?

The Euro standard may appear on the vehicle registration certificate, certificate of conformity or other official vehicle documentation. Its location and format vary between countries.

Does the year of a vehicle determine its Euro standard?

The date of first registration can provide an indication, but it does not always determine the standard with certainty. The official vehicle documents or type-approval information provide the more reliable classification.

Can petrol and diesel vehicles with the same Euro number have different emission limits?

Yes. The applicable emission limits and testing requirements can differ according to the vehicle category, engine and fuel type even when vehicles belong to the same general Euro generation.

Can the Euro standard affect access to a low-emission zone?

Yes. Many low-emission zones use the vehicle's Euro standard together with factors such as fuel type and vehicle category to determine whether it may enter.

Does installing a particulate filter automatically change the Euro standard?

Not normally. The official Euro standard is linked to the vehicle's approved emissions classification. Retrofitting emission-control equipment does not necessarily result in a different official Euro classification.

What is Euro 7?

Euro 7 is the latest European emissions framework for road vehicles. It builds on earlier Euro standards and also introduces requirements covering areas such as non-exhaust particle emissions and battery durability.

21. Nid-de-poule

Un nid-de-poule est un trou ou un creux dans la chaussée causé par l’usure, les intempéries, l’eau, les charges répétées du trafic ou la détérioration du revêtement. Les nids-de-poule peuvent varier fortement en taille et profondeur et se développer progressivement ou s’aggraver après le gel, de fortes pluies ou le passage répété des véhicules.

Ils peuvent affecter la direction, le freinage et la stabilité du véhicule et endommager les pneus, roues ou éléments de suspension. Les conducteurs et cyclistes doivent observer la route, adapter leur vitesse et éviter les manœuvres brusques ou dangereuses lorsqu’ils rencontrent un revêtement endommagé.

Nid-de-poule
What is a pothole?

A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.

How do potholes form?

Potholes can develop through a combination of water, temperature changes, traffic loads and deterioration of the road material. Cracks can gradually expand until pieces of the surface break away.

Why are potholes dangerous?

A pothole can cause a vehicle to change direction suddenly, lose stability or suffer tyre, wheel or suspension damage. Deep potholes can present a particularly serious hazard at higher speeds.

What should you do when you see a pothole?

Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.

Should you brake while driving through a pothole?

If possible, reduce your speed before reaching the pothole. Sudden heavy braking or steering while passing over a damaged surface can make the vehicle less stable.

Are potholes particularly dangerous for motorcycles?

Yes. A pothole can disturb the steering or balance of a motorcycle and may cause the rider to lose control.

Are potholes dangerous for cyclists?

Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.

Can a pothole damage a car?

Yes. Severe impacts can damage tyres, wheel rims, suspension components, steering parts or wheel alignment.

Should you swerve suddenly to avoid a pothole?

No. A sudden evasive movement may create a greater danger by bringing the vehicle into conflict with cyclists, pedestrians, oncoming traffic or vehicles in another lane.

Can a warning sign indicate potholes ahead?

Yes. Depending on the country's traffic-sign system, an uneven-road or general-danger warning sign may be used where poor road conditions create a significant hazard.

22. Chemin

Un chemin est un itinéraire relativement étroit destiné aux piétons et, lorsque cela est autorisé, à d’autres usagers de la route ou à de petits véhicules. Les chemins peuvent traverser des zones urbaines, la campagne, des parcs, des forêts ou relier d’autres routes, et peuvent être revêtus ou non.

Un chemin n’est pas nécessairement identique à un sentier piétonnier ou une piste cyclable. Les usagers autorisés à l’emprunter dépendent de son statut juridique, de sa largeur, de la signalisation routière et de la réglementation locale.

Chemin
What is a path?

A path is a relatively narrow route intended primarily for pedestrians and, where permitted, other road users or small vehicles.

Is a path the same as a footpath?

Not necessarily. A footpath is specifically intended for pedestrians, while a path may also permit cyclists or other users according to local rules.

Is a path the same as a cycle path?

No. A cycle path is specifically designated for bicycles and other permitted users. An ordinary path does not automatically have that legal status.

Can cyclists use a path?

This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.

Can motor vehicles use a path?

This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.

Can a path be part of the public-road network?

Yes. A narrow path can legally form part of the public-road network even when it is unsuitable for ordinary cars.

Does a path need to be paved?

No. Paths can be paved, gravelled, compacted or unsurfaced depending on their location and purpose.

Can traffic signs restrict access to a path?

Yes. Signs can reserve a path for particular road users or prohibit certain vehicles, regardless of whether they could physically fit on it.

Who has priority when a path joins a larger road?

The applicable local priority rules determine who must give way. Special rules often apply when a minor path joins an ordinary road.

Can pedestrians and cyclists share a path?

Yes, where both are permitted. Faster users should adapt their speed and avoid endangering or unnecessarily obstructing pedestrians.

Can a path cross another road?

Yes. At the crossing, users must follow the applicable priority signs, traffic lights, road markings and general right-of-way rules.

Is every narrow route legally a path?

No. Its legal classification depends on the definitions and regulations of the country concerned. A narrow route might instead be a footpath, cycle path, private access road or another type of facility.

23. Particules

Les particules, ou matières particulaires (PM), sont de minuscules particules solides ou gouttelettes liquides en suspension dans l’air. Dans la circulation routière, les émissions de particules peuvent provenir des gaz d’échappement des véhicules, de l’usure des freins, de l’usure des pneus et de l’usure de la chaussée, ainsi que de la poussière remise en suspension par le passage des véhicules.

Les matières particulaires sont généralement classées selon la taille des particules. PM10 désigne les particules d’un diamètre allant jusqu’à environ 10 micromètres, tandis que PM2.5 désigne des particules plus fines allant jusqu’à environ 2,5 micromètres. Les normes d’émissions des véhicules, les filtres à particules et les mesures relatives à la qualité de l’air servent à réduire l’exposition à ces polluants.

Particules
What are particulates?

Particulates, or particulate matter, are very small solid particles or liquid droplets suspended in the air.

What are PM10 and PM2.5?

PM10 refers to particles with a diameter of up to approximately 10 micrometres. PM2.5 refers to finer particles with a diameter of up to approximately 2.5 micrometres.

Where do traffic particulates come from?

Road traffic can produce particles through engine exhaust, brake wear, tyre wear and road-surface wear. Passing traffic can also resuspend dust already present on the road.

Are diesel vehicles a source of particulates?

Yes. Combustion in diesel engines can produce very small soot particles. Modern diesel vehicles commonly use particulate filters to capture a large proportion of these exhaust particles.

What is a particulate filter?

A particulate filter is an exhaust-treatment device designed to trap particulate matter produced by an engine. Diesel particulate filters are commonly known as DPFs.

Do petrol engines produce particulates?

Yes. Petrol engines can also produce particulate emissions, particularly certain direct-injection engines. Appropriate emission-control systems may therefore include particulate filters.

Do electric vehicles produce particulates?

Fully electric vehicles produce no exhaust particulates from a combustion engine, but particles can still result from tyre wear, road wear and braking.

Are brake and tyre particles regulated?

Vehicle-emission regulation is increasingly addressing non-exhaust emissions. The European Euro 7 framework includes requirements concerning brake-particle emissions and tyre abrasion.

Is particulate matter the same as CO2?

No. Particulate matter consists of tiny airborne particles, while carbon dioxide is a gas. They are different types of vehicle emissions and are regulated for different environmental reasons.

How can vehicle particulate emissions be reduced?

Measures include effective particulate filters, cleaner vehicle technologies, correctly maintained emission-control systems and reductions in brake, tyre and road-wear emissions.

24. Pollution de l’air

La pollution de l’air est la présence dans l’air de gaz, de particules ou d’autres substances à des concentrations susceptibles de nuire à la santé humaine, à l’environnement ou aux écosystèmes. La circulation routière contribue à la pollution de l’air par les émissions d’échappement et par des sources hors échappement telles que l’usure des freins, l’usure des pneus et la poussière routière.

Parmi les principaux polluants liés au trafic figurent les oxydes d’azote, les particules, le monoxyde de carbone et les composés organiques volatils. Certains polluants sont émis directement par les véhicules, tandis que d’autres peuvent se former dans l’atmosphère par des réactions chimiques. Les normes d’émissions, les technologies plus propres et les mesures de gestion du trafic servent à réduire ces émissions.

Pollution de l’air
What is air pollution?

Air pollution is contamination of the air by gases, particles or other substances that can adversely affect human health, the environment or ecosystems.

How does road traffic cause air pollution?

Vehicles produce pollutants through fuel combustion, exhaust systems, brake wear, tyre wear and road-surface interaction. Moving traffic can also resuspend dust already present on the road.

Which air pollutants are associated with road traffic?

Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Their relative importance depends on the vehicle, fuel and driving conditions.

What is nitrogen dioxide?

Nitrogen dioxide (NO2) is an air pollutant associated particularly with combustion processes and road traffic. High concentrations are commonly found near busy roads and densely trafficked urban areas.

What is particulate matter?

Particulate matter consists of tiny solid particles or liquid droplets suspended in the air. Road traffic can produce particles from exhaust, brakes, tyres and road surfaces.

Is CO2 the same as ordinary air pollution?

No. Carbon dioxide is primarily regulated as a greenhouse gas because of its contribution to climate change. Local air-quality pollution generally focuses on substances such as nitrogen dioxide, particulate matter, ozone and other pollutants that directly affect air quality and health.

Do electric vehicles cause air pollution?

Fully electric vehicles produce no combustion-engine exhaust emissions while driving, but they can still contribute to non-exhaust particulate emissions through tyres, brakes and road wear.

Can air pollution be worse near busy roads?

Yes. Concentrations of traffic-related pollutants can be higher close to heavily trafficked roads because many emissions occur close to ground level and near where people live and travel.

What is a low-emission zone?

A low-emission zone is an area where access by more polluting vehicles is restricted in order to reduce traffic-related air pollution. Access criteria may depend on factors such as fuel type, vehicle category and emission standard.

How can traffic-related air pollution be reduced?

Measures include cleaner vehicles, stricter emission standards, effective emission-control equipment, low-emission zones, public transport, cycling and walking, as well as traffic-management measures that reduce unnecessary congestion and emissions.

25. Heure de pointe

L’heure de pointe est une période pendant laquelle les routes et les réseaux de transport public connaissent une demande particulièrement élevée, généralement parce qu’un grand nombre de personnes se rendent au travail, à l’école ou à d’autres destinations régulières, ou en reviennent. Elle se produit le plus souvent le matin et en fin d’après-midi ou en soirée les jours ouvrables.

La circulation aux heures de pointe peut entraîner des embouteillages, des vitesses plus faibles, des trajets plus longs et des arrêts fréquents. Les conducteurs doivent maintenir une distance de sécurité, rester patients, anticiper l’évolution du trafic et respecter les éventuelles mesures temporaires ou dynamiques de gestion de la circulation.

Heure de pointe
What is rush hour?

Rush hour is a period when unusually large numbers of people travel at the same time, resulting in increased traffic and often congestion.

When does rush hour occur?

Rush hour commonly occurs during the morning and late afternoon or evening on working days, but the exact times vary according to the city, road and local travel patterns.

Does rush hour always last one hour?

No. The term does not mean that congestion lasts exactly one hour. In busy urban areas, peak traffic conditions may continue for several hours.

Why does traffic become congested during rush hour?

Congestion develops when traffic demand approaches or exceeds the available road capacity. Intersections, merging traffic, collisions, roadworks and weather can make the congestion worse.

Should you increase your following distance in rush-hour traffic?

Yes. Leave sufficient distance to react to sudden braking and frequent changes in traffic speed. Avoid following another vehicle too closely even when traffic is moving slowly.

Should you frequently change lanes during congestion?

Unnecessary lane changes can create additional conflicts and may not significantly reduce journey time. Choose an appropriate lane, observe surrounding traffic and change lane only when it can be done safely.

Can speed limits change during rush hour?

Yes. Roads equipped with variable traffic management may display lower speed limits during congestion. Drivers must follow the speed limit currently indicated.

What is a rush-hour lane?

A rush-hour lane is an additional traffic lane that can be opened during busy periods to increase road capacity. It may use a lane or shoulder that is closed to normal traffic at other times.

Can you use a rush-hour lane whenever traffic is congested?

No. Such a lane may only be used when traffic signals or signs indicate that it is open. Never assume that congestion alone permits its use.

How can you prepare for a journey during rush hour?

Check current traffic conditions and expected journey times, allow additional travel time and consider an alternative route, departure time or mode of transport where appropriate.
