1. Worldwide

Traffic rules differ from country to country, but many basic principles are shared around the world. Countries may drive on the left or right side of the road, use kilometres or miles per hour, and follow different systems for speed limits, priority, parking and road markings. Traffic signs also vary: many countries use European-style red triangular warning signs, while others use systems such as the yellow diamond warning signs common in North America and parts of Oceania.

International agreements have helped make cross-border driving more consistent, especially for road signs, driving permits and vehicle standards, but there is no single worldwide traffic code. Every country sets its own traffic laws and enforcement rules. This worldwide section highlights common traffic-rule concepts, international differences and sign systems, making it easier to compare how driving works across different countries and regions.

Let's explore traffic rules around the world.

Which countries use km/h?

Kilometres per hour (km/h) are used for road speeds in the great majority of countries, including almost all of continental Europe, Canada, Mexico, most of Central and South America, most of Africa and Asia, and countries such as Australia and New Zealand. Ireland also uses km/h despite driving on the left. The relatively small group of countries and territories using mph is listed separately below.

Which countries use mph?

At sovereign-state level, miles per hour (mph) are used for road speeds in the United Kingdom, United States, Antigua and Barbuda, The Bahamas, Belize, Dominica, Grenada, Marshall Islands, Micronesia, Palau, Saint Kitts and Nevis, Saint Lucia and Saint Vincent and the Grenadines. Liberia retains some mixed or legacy mph use alongside km/h. mph is also used in several territories, including Anguilla, the Cayman Islands, Falkland Islands, Guam, Puerto Rico, the Isle of Man, Jersey and Guernsey.

Which countries drive on the left?

Left-hand traffic is used in Antigua and Barbuda, Australia, The Bahamas, Bangladesh, Barbados, Bhutan, Botswana, Brunei, Cyprus, Dominica, Eswatini, Fiji, Grenada, Guyana, India, Indonesia, Ireland, Jamaica, Japan, Kenya, Kiribati, Lesotho, Malawi, Malaysia, Maldives, Malta, Mauritius, Mozambique, Namibia, Nauru, Nepal, New Zealand, Pakistan, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Samoa, Seychelles, Singapore, Solomon Islands, South Africa, Sri Lanka, Suriname, Tanzania, Thailand, Timor-Leste, Tonga, Trinidad and Tobago, Tuvalu, Uganda, the United Kingdom, Zambia and Zimbabwe. Several territories, including Hong Kong and the U.S. Virgin Islands, also drive on the left.

Which countries drive on the right?

All sovereign states not listed among the left-driving countries above generally use right-hand traffic. This includes most of continental Europe, the United States, Canada, Mexico, China, South Korea, the Philippines, most of the Middle East and Africa, and almost all of mainland Central and South America. Territories can differ from the country responsible for them: for example, Hong Kong and Macau drive on the left while mainland China drives on the right.

Which countries use metric measurements on road signs?

Most countries use the metric system for road measurements. Distances are normally shown in kilometres or metres, vehicle dimensions in metres and centimetres, and weight restrictions in tonnes or kilograms. This includes most of Europe, Canada, Mexico, Latin America, Africa, Asia and Oceania. Individual countries can still use a mixture of units for particular signs or older regulations.

Which countries use imperial or US customary measurements on road signs?

The most prominent examples are the United States and United Kingdom. U.S. signs use miles, feet and inches extensively, while British road signs use miles and yards for distance and retain imperial measurements for several other road-sign applications. A number of Caribbean and Pacific countries and territories that use mph also retain miles, feet or other non-metric measurements. Some jurisdictions use a mixture of metric and non-metric units.

Which countries use Vienna Convention-style road signs?

Vienna-style road signs dominate across most of continental Europe, including countries such as Belgium, France, Germany, Italy, Spain, Austria, Switzerland, Poland and the Netherlands, and closely related systems are used in many other parts of Europe, Asia, the Middle East, Africa and Latin America. Typical features include red-bordered triangular warning signs, circular prohibition signs and blue circular mandatory signs. “Vienna-style” is not itself a formal legal classification: some countries use similar designs without being parties to the Convention, while Contracting Parties can retain permitted national variations.

Which countries use MUTCD-style road signs?

The United States uses the Manual on Uniform Traffic Control Devices (MUTCD) as its official national traffic-control-device standard. Separate systems in Canada, Mexico and several countries in Central America and the Caribbean share important North American design characteristics, particularly yellow diamond-shaped warning signs, but they are not literally governed by the U.S. MUTCD. Australia and New Zealand also use yellow diamond warning signs but have their own road-sign standards and should not simply be classified as MUTCD countries.

Which countries use STOP, PARE or other words on stop signs?

STOP is the most internationally widespread wording and is used even in many countries where English is not the main language. PARE is used in Brazil and in several Spanish-speaking South American countries, including Argentina, Chile, Colombia, Peru and Uruguay. ALTO is used in Mexico and parts of Central America. Other local forms exist, such as ARRÊT in parts of French-speaking Canada and DUR in Turkey. Some countries display both a local-language word and STOP.

Which countries use GIVE WAY, YIELD or other wording?

The United States uses YIELD, while GIVE WAY is standard terminology in countries such as the United Kingdom, Ireland, Australia and New Zealand. Many Vienna-style systems use the familiar red-bordered inverted triangle without any wording. Spanish-language rules commonly refer to CEDA EL PASO, while Portuguese-language systems use terms such as Dê a Preferência. The shape is therefore often more internationally consistent than the wording.

Which countries require daytime headlights?

Daytime-light rules exist in many countries but are not identical. Broad requirements apply in countries including Finland, Estonia, Lithuania, Bulgaria, Poland, Slovenia and Uruguay, generally allowing dipped headlights and/or approved daytime running lights. Other countries apply the requirement only to particular roads: for example, Argentina requires lights on national routes, while Peru requires low beams 24 hours a day on its national and departmental/regional road networks. Seasonal and vehicle-specific rules also exist elsewhere.

Which countries require winter tyres?

Winter tyres are compulsory during specified periods or winter conditions in a number of countries, including Finland, Sweden, Lithuania, Austria, Germany, Czechia, Slovenia and Croatia. The exact rule varies considerably: some countries use fixed winter dates, others require winter tyres only when there is snow, ice or other winter weather, and some distinguish between vehicle classes. Many countries with occasional snow, including Belgium and the Netherlands, have no general winter-tyre requirement.

Which countries use priority from the right?

Priority from the right is common at equal, uncontrolled intersections in much of continental Europe, including Belgium, France, Germany, the Netherlands, Austria, Switzerland, Poland, Czechia, Slovakia, Hungary, Romania, Finland, Sweden and Norway. Similar rules also exist in countries such as Argentina and Uruguay. It is never safe to treat this as a universal rule: priority roads, signs, traffic lights, roundabouts and other statutory exceptions can override it.

Which countries require drivers to carry a warning triangle?

Warning triangles are compulsory equipment in many countries, including Belgium, Germany, Poland, Portugal, Italy, Greece and Argentina, although the number required and the rules for placing them differ. Spain is now an important exception: from 1 January 2026, Spanish-registered vehicles use the connected V-16 warning beacon instead of traditional triangles. Foreign vehicles in international traffic can still use triangles in Spain under the applicable international rules.

Which countries require drivers to carry a reflective safety vest?

Reflective-vest requirements are common in Europe. Countries with requirements include Belgium, France, Germany, Austria, Italy, Portugal, Spain, Lithuania, Slovenia and Croatia, among others. The legal detail varies: in some countries the vest must be carried inside the vehicle, while elsewhere the principal obligation is to wear it when leaving a stopped vehicle on or beside the road.

Which countries require a fire extinguisher or first-aid kit?

Requirements vary widely. Countries requiring both a fire extinguisher and first-aid equipment for ordinary cars include examples such as Bulgaria, Greece and Lithuania. Poland requires a fire extinguisher, while Germany and Czechia require first-aid equipment. Argentina requires a compliant fire extinguisher in ordinary cars. Requirements can depend on vehicle category, registration country and whether the vehicle is used privately or commercially.

2. Motorway

A motorway is a road specially designed and signposted for motor traffic. Motorways normally have separate carriageways for opposing traffic, controlled access through designated entrances and exits, no direct access to neighbouring properties, and no level crossings with other roads, railways or paths.

Special traffic rules apply on motorways. The permitted road users, speed limits, lane rules, tolls and emergency procedures vary between countries, so drivers must follow the local traffic signs and regulations.

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. Expressway

An expressway is a road intended to carry through traffic efficiently, usually at higher speeds than ordinary roads. Expressways often have limited access, multiple lanes, separated carriageways or grade-separated junctions, but their design and legal status vary between countries.

An expressway is not always a motorway. It may have intersections, traffic lights or direct access, and the permitted road users, speed limits and special rules depend on local signs and regulations.

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. Residential area

A residential area is a street or group of streets where housing and access to local properties are the main functions. Drivers should expect pedestrians, cyclists, children, parked vehicles and vehicles entering or leaving driveways.

Some countries identify particular residential areas with traffic signs and apply special low-speed and residential-area rules. The speed limit, pedestrian rights, parking rules and permitted road users therefore depend on local signs and regulations.

How can you recognise a residential area?

A residential area commonly contains homes, driveways, parked vehicles and local streets. It may also have special entrance signs, traffic-calming measures or shared road space, but its appearance and legal status differ between countries.

Is a residential area the same as a built-up area?

Not necessarily. A built-up area may include residential, commercial and industrial streets. A residential area is primarily associated with housing and local access and may form only one part of a larger built-up area.

Is every residential neighbourhood a legally designated residential zone?

No. In many countries, special residential-zone rules apply only where an official entrance sign is displayed. An ordinary neighbourhood may remain subject to the normal rules for the surrounding road or built-up area.

What is the speed limit in a residential area?

There is no universal residential-area speed limit. Some countries apply a very low limit in signposted residential or shared-space zones, while ordinary residential streets may follow the general built-up-area limit or a posted zone limit.

Do pedestrians have priority in a residential area?

The rights of pedestrians depend on the country and the type of residential area. In some signposted shared-space zones, pedestrians may use the whole road and drivers must give them special consideration. On ordinary residential streets, the normal pedestrian and crossing rules may apply.

May children play in a residential area?

Playing may be expressly permitted in certain legally designated residential or shared-space zones. This is not automatically allowed on every residential street. Drivers should nevertheless remain especially alert for children, who may enter the road unexpectedly.

Which road users may enter a residential area?

Residential areas are normally accessible to local motor traffic, cyclists and pedestrians, but additional signs may restrict certain vehicles or through traffic. A residential area is therefore not necessarily a pedestrian-only zone.

How should you drive in a residential area?

Drive at a speed that allows you to stop safely, watch both sides of the road and expect pedestrians, cyclists, children, pets and vehicles emerging from entrances. Leave enough space and avoid unnecessary acceleration, noise or aggressive overtaking.

May you overtake in a residential area?

Overtaking is not universally prohibited, but it may be restricted by local law, signs or road design. Even where it is permitted, drivers should not overtake when the limited space or presence of vulnerable road users makes it unsafe.

Where may you park in a residential area?

Follow the local parking signs, markings and general parking rules. Do not block entrances, pavements, crossings, sight lines or the passage of other road users. Special residential zones may permit parking only in designated spaces.

What is the difference between a residential area and a pedestrian zone?

Motor vehicles are normally still permitted in a residential area, although they may be subject to strict speed and parking rules. In a pedestrian zone, vehicle access is generally prohibited or limited to specific users, purposes or times.

5. Built-up area

A built-up area is an area containing concentrated buildings, streets and regular local activity. Drivers should expect more pedestrians, cyclists, intersections, parked vehicles, public transport and vehicles entering or leaving properties.

Many countries apply special traffic rules and lower default speed limits within built-up areas. The area may be identified by entrance and exit signs, street lighting or other legal criteria, so drivers must follow local signs and regulations.

Wikimedia.org • Janter • CC BY-SA
How can you recognise a built-up area?

A built-up area commonly contains closely spaced buildings, local streets, intersections, pavements, pedestrians and regular access to properties. Some countries use official entrance and exit signs, while others define built-up roads through street lighting or other legal criteria.

Is a built-up area the same as a town or city?

Not necessarily. A legally defined built-up area may cover only part of a town or may include several connected settlements. Administrative boundaries and traffic-law boundaries do not always coincide.

Is a built-up area the same as a residential area?

No. A built-up area may contain residential, commercial, industrial and public streets. A residential area is mainly associated with housing and may form only one part of a built-up area.

How does a built-up area begin and end?

In many countries, the area begins and ends at official traffic signs. In others, road lighting, development or another legal definition determines whether a road is inside a built-up area. Drivers should not rely only on the appearance of the surroundings.

What is the speed limit in a built-up area?

There is no universal built-up-area speed limit. The default limit differs between countries and regions, and traffic signs may impose a lower or higher limit on a particular road or throughout a zone.

Does the built-up-area speed limit apply on every road?

The general limit normally applies unless a traffic sign, road category or special rule establishes another limit. Major urban roads may have a higher signed limit, while residential streets, school areas and city centres may have lower limits.

Does a speed-limit sign remain valid after an intersection?

This depends on local law and the type of sign. A local speed restriction may end at the next intersection in some countries, while a zonal speed limit normally continues until an end-of-zone sign.

Do pedestrians have priority throughout a built-up area?

No. Pedestrians do not automatically have priority everywhere merely because they are in a built-up area. Their priority depends on crossings, traffic signals, shared-space rules and local law. Drivers must nevertheless remain especially alert for pedestrians.

How should you drive in a built-up area?

Adjust your speed, watch both sides of the road and expect frequent changes in traffic. Be prepared for pedestrians crossing, cyclists changing position, buses leaving stops, opening vehicle doors and vehicles emerging from side roads or driveways.

Are parking rules different in a built-up area?

Some countries apply additional stopping and parking restrictions inside built-up areas. Drivers must follow signs, markings and local rules and must not obstruct pavements, crossings, entrances, cycle facilities or visibility at intersections.

What is the difference between a built-up area and a speed zone?

A built-up area is a broader traffic-law area that may contain many different roads and activities. A speed zone imposes a particular maximum speed throughout the signed zone and may be located inside or outside a built-up area.

When do the built-up-area rules end?

The rules end at the legally defined boundary, which may be indicated by an end-of-built-up-area sign. After that point, the rules and default speed limits for roads outside built-up areas normally apply.

6. Zone

A traffic zone is an area in which a traffic rule applies throughout all included roads or road sections. The rule normally begins at a zone-entry sign and remains applicable until the corresponding end-of-zone sign is passed.

Zones may regulate speed, parking, access, vehicle categories, emissions or other traffic behaviour. The signs used, the roads covered and the effect of intersections or local exceptions depend on local traffic law.

Zone with speed limit 30 km/h. (Berlin-Tiergarten, Germany)
Wikimedia.org • Lukas Beck • CC BY-SA
What is a traffic zone?

A traffic zone is a defined area in which a particular restriction, prohibition or obligation applies throughout the included roads rather than only at one location.

How can you recognise a traffic zone?

A traffic zone normally begins with a zone-entry sign showing the applicable rule. A corresponding end-of-zone sign indicates where that rule stops applying.

What is the difference between a zone sign and an ordinary traffic sign?

An ordinary sign usually applies to a particular road, direction, lane or section. A zone sign applies throughout a designated area, which may contain several roads and intersections.

Does a zone normally continue after an intersection?

Usually, yes. A zonal rule commonly continues through intersections until an end-of-zone sign is reached. The exact effect of intersections depends on local law.

How does a traffic zone end?

A traffic zone normally ends when you pass the corresponding end-of-zone sign. The normal road rules or another signed regulation then apply.

Can more than one rule apply inside a zone?

Yes. A zone may contain several regulations, such as a speed limit together with parking or access restrictions. Drivers must observe every applicable sign.

Can another traffic sign apply inside a zone?

Yes. A local sign may introduce a different or more restrictive rule on a particular road or section. Whether the original zonal rule resumes afterwards depends on local law and the type of regulation.

What types of traffic zones exist?

Common examples include speed zones, parking zones, low-emission zones, pedestrian zones, cycling zones, school zones and zones restricting particular vehicle categories.

Is a traffic zone the same as a built-up area?

No. A built-up area is a broader legally defined urban area. A traffic zone imposes a specific signed rule and may be located inside or outside a built-up area.

Is a traffic zone the same as a residential area?

No. A residential area describes an area mainly used for housing. It may contain one or more traffic zones, but the terms do not automatically have the same legal meaning.

Does a zonal rule apply to every road user?

Not necessarily. The sign, symbol or additional panel may limit the rule to particular vehicles, road users, times or circumstances.

What should you do when entering a traffic zone?

Observe the entrance sign carefully, identify every displayed rule and remember that the regulation may continue across several roads and intersections until the zone ends.

7. Speed limit

A speed limit is the maximum legal speed permitted on a road, lane or within a designated area. It may be established by general traffic law or indicated by fixed, variable or temporary traffic signs.

A speed limit is a maximum, not a target speed. Drivers must travel more slowly whenever traffic, visibility, weather, road conditions, vulnerable road users or the condition of the vehicle make the maximum permitted speed unsafe.

Speed limit of 70 km/h. (Mahrenholz, Germany)
Wikimedia.org • Kirchenfan • CC0
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.

8. Minimum speed

A minimum speed is the lowest speed that vehicles are required to maintain on a particular road or under specified conditions. Minimum-speed rules are intended to prevent vehicles travelling unnecessarily slowly from disrupting traffic or creating large speed differences between road users.

A minimum speed does not require drivers to maintain that speed when traffic, weather, visibility, road conditions or safety require them to slow down. The way minimum speeds are indicated and enforced varies between countries.

What is a minimum speed?

A minimum speed is the lowest speed that vehicles are normally required to maintain on a particular road or in a specified traffic situation.

Must you maintain the minimum speed in dangerous conditions?

No. Safety takes priority. Drivers may need to travel more slowly because of congestion, poor weather, limited visibility, roadworks or another legitimate reason.

Why are minimum speeds used?

Minimum speeds can help reduce excessive differences in speed between vehicles and prevent unnecessarily slow traffic from obstructing normal traffic flow.

9. Advisory speed

An advisory speed is a recommended speed for a particular road section or hazard rather than a legally imposed maximum speed. It may be shown near bends, junctions, steep gradients, roadworks or other locations where a lower speed can help drivers negotiate the road safely.

Drivers should treat an advisory speed as guidance for safe driving conditions and should travel even more slowly when weather, visibility, traffic or road conditions require it. A separate legally binding speed limit must still be obeyed.

Advisory speed of 30 km/h. (Haute-Savoie, France)
Wikimedia.org • Marc Mongenet • CC BY-SA
What is an advisory speed?

An advisory speed is a recommended speed intended to help drivers negotiate a road section or hazard safely.

Is an advisory speed the same as a speed limit?

No. An advisory speed normally provides guidance, while a regulatory maximum-speed sign establishes a legally enforceable speed limit.

Can you drive slower than an advisory speed?

Yes. Drivers should reduce their speed further whenever road, traffic, visibility or weather conditions make the recommended speed unsafe.

10. Footpath

A footpath is a path or part of a road intended primarily for pedestrian traffic. It may run alongside a road, through a park or residential area, or independently from roads used by motor vehicles.

A footpath may be reserved exclusively for pedestrians or may form part of a shared route with cyclists or other permitted users. Access, priority and permitted users depend on the traffic signs and local regulations applying to the path.

A path for pedestrians. (Geneva, Switzerland)
Wikimedia.org • Marc Mongenet • CC BY-SA
What is a footpath?

A footpath is a path or part of a road intended primarily for pedestrians.

Is a footpath the same as a pavement?

Not necessarily. A pavement or sidewalk normally runs alongside a roadway, while a footpath may follow an independent route or pass through an area without an adjacent roadway.

Who may use a footpath?

Pedestrians are the primary users. Depending on the signs and local regulations, cyclists or other categories may also be permitted on shared paths.

Can cyclists use a pedestrian-only footpath?

Normally no when the path is specifically reserved for pedestrians. Cyclists may have to dismount unless local rules or signs allow cycling.

Can someone walking a bicycle use a footpath?

In many countries, a person walking a bicycle by hand is treated as a pedestrian and may therefore use pedestrian facilities, subject to local rules.

Can motor vehicles use a footpath?

Normally no when the route is reserved for pedestrians. Limited access may sometimes be authorised for maintenance, emergency or other specific purposes.

Can a footpath be shared with cyclists?

Yes. A route may be designated as a shared pedestrian-and-cycle path. Users must follow any signs indicating how the space should be shared.

Do pedestrians have priority on a shared footpath?

This depends on the local traffic rules and type of shared facility. Cyclists and other permitted users should always avoid endangering pedestrians.

Can a footpath cross a roadway?

Yes. Where a path crosses a roadway, pedestrians must follow the applicable crossing, priority and traffic-light rules.

Can a footpath be part of the public road?

Yes. Pedestrian paths can form part of the wider public-road network even though ordinary motor traffic may not use them.

Can a footpath have its own traffic sign?

Yes. Many countries use a specific pedestrian symbol to indicate a path reserved or compulsory for pedestrians.

What should cyclists do when a footpath is not open to cycling?

Use the appropriate cycle facility or roadway. Where local law permits it, a cyclist may also dismount and continue as a pedestrian.

11. Bike path

A bike path is a part of a road or a separate route intended primarily or exclusively for people riding bicycles. It may be physically separated from motor traffic, marked on the road surface or identified by traffic signs.

Bike paths may be one-way, two-way or shared with other road users. The permitted users, direction of travel, priority rules and obligation to use the path depend on local traffic signs and regulations.

Path for cyclists. (Auvergne-Rhône-Alpes, France)
Wikimedia.org • Tabl-trai • CC BY-SA
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.

12. Shared-use path

A shared-use path is a path or part of a road intended for use by both pedestrians and cyclists. Unlike facilities where pedestrians and cyclists have clearly separated sections, users of a shared-use path normally travel within the same general space.

Because users may travel at very different speeds, cyclists should approach pedestrians carefully, adapt their speed and leave sufficient space when passing. The permitted users, priority rules and any speed restrictions depend on the local traffic signs and regulations.

What is a shared-use path?

A shared-use path is a path or part of a road intended to be used by both pedestrians and cyclists.

Is a shared-use path the same as a cycle path?

Not necessarily. A cycle path is primarily intended for cyclists, while a shared-use path is specifically intended to accommodate pedestrians and cyclists together.

Do pedestrians and cyclists have separate sides on a shared-use path?

Not always. On a genuinely shared path, both categories may use the same space. Other facilities may divide pedestrians and cyclists into separate sections using signs, markings or physical separation.

Should cyclists slow down near pedestrians?

Yes. Cyclists should adapt their speed when approaching or passing pedestrians and leave sufficient space to avoid creating danger or discomfort.

Can cyclists ring a bell before passing pedestrians?

Yes, where appropriate. An audible warning can help alert pedestrians before a cyclist passes, but it should be used considerately and does not give the cyclist priority.

Do cyclists automatically have priority over pedestrians?

No. The applicable priority and conduct rules depend on local law. On a shared facility, cyclists should expect pedestrians to move within the available space.

Can mopeds use a shared-use path?

This depends on the signs and local vehicle classifications. Some shared facilities are limited to pedestrians and bicycles, while others also permit specified moped categories.

Can speed pedelecs use a shared-use path?

This depends on local law. Because speed pedelecs can travel substantially faster than ordinary bicycles, some countries or facilities exclude them from pedestrian-and-cycle shared paths.

Can motor vehicles use a shared-use path?

Normally no. Motor vehicles may use such a path only where a specific exception or local rule permits access, for example for maintenance or emergency purposes.

Can a shared-use path cross a roadway?

Yes. At crossings, pedestrians and cyclists must follow the applicable traffic lights, priority signs, road markings and crossing rules.

Can a shared-use path be two-way?

Yes. Many shared-use paths carry pedestrians and cyclists travelling in both directions. Users should therefore remain alert for approaching traffic from ahead as well as users travelling in the same direction.

What should cyclists do when a shared-use path is crowded?

Reduce speed and be prepared to stop. Crowded conditions may make normal cycling speed unsafe even when no specific lower speed limit is posted.

13. Separated path

A separated path is a path or part of a road where different categories of road users, typically pedestrians and cyclists, are assigned separate sections of the same overall route. The sections may be distinguished by road markings, different paving materials, a kerb or another physical separation.

Users should remain within the part of the path intended for them and take particular care where the sections cross, merge or connect with roads. The permitted users, priority rules and any speed restrictions depend on the local traffic signs and regulations.

What is a separated path?

A separated path is a route where pedestrians, cyclists or other permitted users have clearly designated sections rather than sharing the same space.

How are the different parts of a separated path identified?

The sections may be separated by a painted line, different paving materials, a kerb, verge or another physical division. Traffic signs may also show which side each category should use.

Is a separated path the same as a shared-use path?

No. On a shared-use path, pedestrians and cyclists normally use the same space. On a separated path, each category has its own designated section.

Which side should pedestrians use?

Pedestrians should use the section indicated for pedestrians by the signs, symbols, markings or layout of the path.

Which side should cyclists use?

Cyclists should use the section designated for bicycles and should avoid unnecessarily entering the pedestrian section.

Can pedestrians walk in the cycling section?

Normally they should remain in the pedestrian section where one is specifically provided. Local rules may nevertheless allow exceptions where their designated section is obstructed or unusable.

Can cyclists use the pedestrian section?

Normally no. Cyclists should remain in the cycling section unless local rules specifically permit otherwise or they dismount and become pedestrians.

Can mopeds use a separated path?

This depends on the traffic signs and local vehicle classifications. Some separated facilities also permit specified moped categories on the cycling section.

Can a separated path be two-way?

Yes. The cycling section may carry traffic in one or both directions depending on the signs and local road arrangement.

What happens where the pedestrian and cycling sections cross?

Users should approach carefully and follow any priority signs, markings or crossing rules. Neither category should assume priority simply because they are using a separated path.

Can a separated path cross a roadway?

Yes. At the crossing, users must follow the applicable traffic lights, priority rules and road markings.

Why are pedestrians and cyclists separated?

Separation can reduce conflicts between users travelling at different speeds and provide a clearer and more predictable route for both pedestrians and cyclists.

14. Pedestrian warning

A pedestrian warning is a traffic warning indicating that pedestrians may be crossing or entering the roadway ahead. It is commonly used near pedestrian crossings or other locations where drivers need advance notice of frequent pedestrian activity.

Drivers approaching a pedestrian warning should reduce speed when necessary, watch carefully for pedestrians and be prepared to stop. The design of the warning sign and the priority rules at the crossing vary between countries.

What does a pedestrian warning mean?

A pedestrian warning alerts drivers that pedestrians may be crossing or entering the road ahead.

Where are pedestrian warning signs commonly used?

They are commonly placed near pedestrian crossings or other locations with significant pedestrian activity.

How should you react to a pedestrian warning?

Reduce speed when necessary, watch both sides of the road and be prepared to give way or stop for pedestrians according to the applicable traffic rules.

15. Tunnel

A tunnel is a covered passage that carries a road through or beneath an obstacle such as a hill, mountain, building, waterway or another transport route. Road tunnels may contain one or more traffic lanes and can carry traffic in one or both directions.

Driving in a tunnel requires particular attention because visibility, available escape routes and space for avoiding hazards are limited. Drivers should follow the applicable lighting, speed, lane and following-distance rules and pay attention to emergency exits, traffic signals and variable-message signs.

What is a road tunnel?

A road tunnel is a covered passage that carries a road through or beneath an obstacle.

Should you use headlights in a tunnel?

Follow the local lighting rules and traffic signs. Many countries require dipped headlights in tunnels even during daylight, while general visibility rules may also require vehicle lights.

Should you increase your following distance in a tunnel?

Yes. Additional distance gives more time to react to sudden congestion, a breakdown or another hazard where escape space may be limited.

Can you stop or park in a tunnel?

Voluntary stopping and parking are generally prohibited or strongly restricted in road tunnels. Drivers should stop only where permitted or when traffic, an emergency or another unavoidable situation requires it.

Can you reverse or make a U-turn in a tunnel?

Normally this should not be done unless specifically authorised or directed by emergency or traffic-control personnel. Motorway tunnels are additionally subject to the normal motorway prohibitions on reversing and U-turns.

What should you do if traffic stops in a tunnel?

Keep a safe distance from the vehicle ahead, follow traffic signals and instructions and avoid blocking emergency access. Switch on hazard warning lights where appropriate to warn following traffic.

What should you do if your vehicle breaks down in a tunnel?

Move into an emergency bay or other safe position if possible, switch on the hazard warning lights and follow the tunnel's emergency procedures. Use an emergency telephone or contact the emergency services where necessary.

What should you do if there is a fire in a tunnel?

Follow the emergency signs and instructions immediately. If evacuation is necessary, leave the vehicle and use the indicated emergency exit rather than remaining in a dangerous traffic or smoke-filled area.

What are tunnel emergency exits?

Emergency exits provide a route away from the traffic tunnel during incidents such as a fire. Signs may indicate the nearest exit and the direction or distance to it.

Should you remove sunglasses before entering a tunnel?

Where necessary, removing dark sunglasses before entering can help your eyes adapt more quickly to the lower light level inside the tunnel.

Can speed limits change inside a tunnel?

Yes. Tunnels may have permanent or variable speed restrictions. Drivers must follow the speed limit currently indicated.

Can dangerous goods be restricted in tunnels?

Yes. Certain tunnels may restrict vehicles carrying dangerous goods because an incident in an enclosed space can create additional risks. Follow all applicable tunnel-category and dangerous-goods signs.

16. Bridge

A bridge is a structure that carries a road, path or railway over an obstacle such as a river, valley, railway line or another road. A road bridge may carry one or more roadways together with pedestrian or cycling facilities.

Drivers should follow any speed, weight, height, width or vehicle-access restrictions applying to the bridge. Particular care may be necessary on narrow, exposed or movable bridges and when weather conditions such as wind, rain or ice affect the road surface.

What is a bridge?

A bridge is a structure that carries a road, path or railway over an obstacle such as a river, valley, railway or another road.

Can a bridge carry several traffic lanes?

Yes. Road bridges may carry one or several traffic lanes and can also contain pavements, cycle facilities or public-transport infrastructure.

Can a bridge have a weight limit?

Yes. A bridge may have restrictions on the maximum vehicle mass or axle load that it can safely accommodate. Drivers of heavy vehicles must obey the applicable signs.

Can a bridge have a width or height restriction?

Yes. Narrow bridges or structures forming part of a bridge can have width, height or other dimensional restrictions indicated by traffic signs.

What is a movable bridge?

A movable bridge is a bridge that can open, lift, swing or otherwise move to allow ships or other traffic to pass beneath or through it.

What should you do when a movable bridge is opening?

Stop when required by the traffic lights, barriers or other signals and remain behind the designated stopping point until the crossing is reopened.

Can bridges become slippery?

Yes. Bridge surfaces can become wet, icy or slippery and may sometimes cool differently from the surrounding road. Drivers should adapt their speed to the actual conditions.

Can strong winds be dangerous on a bridge?

Yes. Exposed bridges can be affected by crosswinds, particularly for motorcycles, bicycles, high-sided vehicles and vehicles towing trailers.

Can you stop or park on a bridge?

This depends on the local traffic rules, road layout and signs. Stopping or parking may be prohibited where it would create danger, obstruct traffic or reduce the available road width.

Can pedestrians and cyclists use a bridge?

Yes, where permitted. Bridges may provide pavements, cycle paths or shared facilities, while high-speed or restricted bridges may prohibit certain road users.

Can traffic be restricted to one direction on a narrow bridge?

Yes. Priority signs, traffic lights or other traffic-management measures may control which direction passes first where two-way traffic cannot safely meet.

Should you overtake on a narrow bridge?

Only when overtaking is legal and clearly safe. Limited width or visibility can make overtaking inappropriate even where no specific prohibition is shown.

17. Cycling street

A cycling street is a street designed or legally designated to give cyclists a prominent position in mixed traffic. Motor vehicles may usually enter, but they must adapt their speed and driving behaviour to the presence of cyclists.

Depending on the country, cyclists may be permitted to use more of the carriageway and motor vehicles may be prohibited from overtaking them. The speed limit, priority rules, permitted vehicles and beginning and end of the street depend on local traffic signs and regulations.

What is a cycling street?

A cycling street is a road where cycling is given a prominent position while motor vehicles may usually continue to use the road under additional restrictions.

How can you recognise a cycling street?

It may be identified by special entrance signs, bicycle symbols, coloured surfacing or distinctive road markings. The legally required signs differ between countries.

Is a cycling street the same as a bike path?

No. A bike path is a separate part of the road or a separate route intended for cyclists. On a cycling street, cyclists and motor vehicles normally share the carriageway.

Is a cycling street the same as a cycling zone?

Not always. A cycling street may refer to one individual street, while a cycling zone may include several connected streets governed by the same rules. Local terminology varies.

May motor vehicles use a cycling street?

Usually, yes. A cycling street is not normally closed to motor traffic, although access may be restricted by additional signs or local regulations.

Do cyclists have to stay close to the edge of the road?

This depends on local law. In some cycling streets, cyclists may use a larger part of the carriageway or ride in the centre of the lane. In others, the normal positioning rules continue to apply.

May cyclists ride side by side?

This depends on the rules of the country and the available road width. Cyclists may often ride side by side where this does not endanger or unlawfully obstruct other road users.

May motor vehicles overtake cyclists?

Some countries expressly prohibit motor vehicles from overtaking cyclists on cycling streets. Elsewhere, overtaking may remain permitted only when the legally required distance and other safety conditions can be respected.

May cyclists overtake motor vehicles?

Normally, cyclists may overtake other vehicles when the manoeuvre is permitted and can be completed safely. They must still observe local overtaking, lane and intersection rules.

What is the speed limit on a cycling street?

There is no universal speed limit. Many countries impose a low maximum speed, commonly 30 km/h or less, but drivers must follow the signs and laws applying locally.

Do cyclists automatically have priority?

No. A cycling street does not normally give cyclists automatic priority at every intersection. Traffic lights, priority signs, crossings and the ordinary priority rules remain applicable.

Do pedestrians have special rights on a cycling street?

Not necessarily. Pedestrians normally use pavements, crossings and other designated facilities. A cycling street is different from a pedestrian zone or residential shared-space area.

May you stop or park on a cycling street?

Stopping and parking depend on the ordinary rules and any local signs or markings. Vehicles must not block cyclists, pavements, crossings, entrances or other traffic.

Does a cycling street always have red surfacing?

No. Coloured surfacing may make the street easier to recognise, but it does not necessarily have legal meaning by itself. The official signs and local regulations determine which rules apply.

When do the cycling-street rules end?

The special rules normally end at an end sign, the end of the designated street or another legally defined boundary. The exact rule differs between countries.

18. Pedestrian zone

A pedestrian zone is an area consisting of one or more streets that are reserved primarily for pedestrians. Motor-vehicle access is normally prohibited or restricted to authorised users, particular purposes or specified times.

Pedestrians may usually use the full width of the available road space. Rules concerning cyclists, deliveries, public transport, vehicle speed, stopping and parking depend on local traffic signs and regulations.

Wikimedia.org • Marc Mongenet • CC BY-SA
What is a pedestrian zone?

A pedestrian zone is an area where pedestrians are the principal road users and ordinary motor-vehicle access is prohibited or strictly restricted.

How can you recognise a pedestrian zone?

A pedestrian zone is normally identified by a special entrance sign. An end sign indicates where the pedestrian-zone rules stop applying.

Is a pedestrian zone the same as a pavement?

No. A pavement is a part of a road intended for pedestrians. A pedestrian zone may include the entire width of one or more streets, squares or other public spaces.

Is a pedestrian zone completely free of vehicles?

Not always. Emergency vehicles, maintenance vehicles, public transport, delivery vehicles, residents or other authorised traffic may be permitted under local rules.

May cyclists enter a pedestrian zone?

This depends on the traffic signs and local law. Cycling may be permitted at all times, during specified hours or not at all. Cyclists who are not permitted to ride may normally walk while pushing their bicycles.

Must cyclists give way to pedestrians?

Where cycling is permitted, cyclists must normally adapt their speed and avoid hindering or endangering pedestrians. They may be required to dismount when the zone is crowded.

May electric scooters enter a pedestrian zone?

This depends on how electric scooters are legally classified and on the signs displayed. They may be treated as pedestrians at very low speeds, as cyclists or as another vehicle category.

May pedestrians use the whole street?

Usually, yes. Pedestrians may generally use the full width of the pedestrian zone, although marked sections may be reserved for authorised vehicles, cyclists or public transport.

Do pedestrians have priority over authorised vehicles?

Authorised drivers must normally travel cautiously, leave pedestrians sufficient space and stop when necessary. The precise priority rule depends on local law.

What is the speed limit for authorised vehicles?

There is no universal numerical limit. Many countries require authorised vehicles to travel at walking pace or another very low speed.

May children play in a pedestrian zone?

Playing may be permitted because the area is primarily reserved for pedestrians, but this depends on local law. Children must still be supervised where authorised vehicles, cyclists or public transport are present.

May vehicles enter for deliveries?

Deliveries may be permitted during specified hours or under particular access conditions. Drivers must observe the information displayed at the entrance.

May taxis enter a pedestrian zone?

Taxis may be permitted to enter for passenger collection or drop-off, but access may be restricted to certain destinations, times or permit holders.

May you stop or park in a pedestrian zone?

Parking is normally prohibited or limited to specially authorised places. Brief stopping for authorised loading, unloading or passenger access may be permitted under local rules.

Does an intersection end a pedestrian zone?

Not necessarily. A pedestrian zone may include several connected streets and intersections. Its rules normally continue until the corresponding end sign is passed.

What is the difference between a pedestrian zone and a residential shared-space area?

A pedestrian zone is primarily reserved for pedestrians and usually restricts motor traffic. A residential shared-space area normally permits general local traffic but imposes very low speeds and special pedestrian and parking rules.

When do the pedestrian-zone rules end?

The special rules normally end at an end-of-pedestrian-zone sign. The ordinary rules of the surrounding road or another signed zone then apply.

19. Speed bump

A speed bump is a raised traffic-calming device placed across all or part of a road to make drivers reduce their speed. It is commonly used near homes, schools, crossings, parking areas and other places where low vehicle speeds are important.

Speed bumps vary in shape, height and legal status. Drivers should approach them at a low, controlled speed and follow any warning signs or speed limits that apply.

Warning for a speed bump. (Haute-Savoie, France)
Wikimedia.org • Marc Mongenet • CC BY-SA
What is the purpose of a speed bump?

A speed bump is intended to physically reduce vehicle speeds. It encourages drivers to slow down in places where pedestrians, cyclists, children or local traffic may be present.

How can you recognise a speed bump?

A speed bump is a raised section extending across all or part of the road. It may be marked with contrasting paint, road markings or warning signs to make it more visible.

Is a speed bump the same as a speed table?

No. A speed bump or speed hump normally has a rounded profile. A speed table has ramps leading to a longer, flat raised section that may contain an intersection or pedestrian crossing.

Is a speed cushion the same as a speed bump?

No. A speed cushion is a narrower raised device that does not cover the full width of a traffic lane. Its design may allow buses and emergency vehicles to pass with less disturbance while still slowing smaller vehicles.

Is there a universal speed limit over a speed bump?

No. The legal speed depends on the country, traffic signs and road type. Even when no special limit applies, drivers must cross the device at a speed that is safe for the road, vehicle and passengers.

How should you approach a speed bump?

Check surrounding traffic, reduce your speed smoothly and approach in a straight line where possible. Avoid sudden braking immediately before the bump.

Should you brake while crossing a speed bump?

Most of the necessary braking should be completed before reaching the raised surface. Cross at a steady, low speed and avoid harsh braking or acceleration while the wheels are on the device.

Should you drive across a speed bump at an angle?

Normally not. Cross in the normal direction of the traffic lane unless the road layout requires otherwise. Driving diagonally may place the vehicle in the path of approaching or overtaking traffic.

May motorcycles and bicycles use a speed bump?

Yes. Riders should reduce speed, keep the vehicle stable and cross as directly as possible. Painted or wet raised surfaces may provide less grip.

Do pedestrians have priority at a speed bump?

Not automatically. A speed bump does not by itself create a pedestrian crossing. Pedestrian priority depends on crossings, traffic signals, signs and local law.

Does a speed bump change priority at an intersection?

No. The presence of a raised surface does not normally change the priority rules. Drivers must continue to follow traffic signs, signals and the ordinary intersection rules.

May you overtake on a speed bump?

Overtaking may be restricted by local law or signs. Even where it is not expressly prohibited, drivers should avoid overtaking when the raised surface, limited space or nearby vulnerable road users make the manoeuvre unsafe.

May you stop or park on a speed bump?

This depends on local law. Stopping or parking may be prohibited because the vehicle could obstruct visibility, traffic flow or the purpose of the traffic-calming device.

Can a speed bump damage a vehicle?

A correctly designed speed bump should be crossed safely at an appropriate speed. Crossing too quickly may damage tyres, wheels, suspension, bodywork or cargo and may cause passengers discomfort.

Does the road speed limit change after a speed bump?

Not necessarily. A special limit may apply only to the raised device, while a signed speed restriction or speed zone may continue beyond it. Drivers must follow the applicable signs and local rules.

Why do buses and emergency vehicles sometimes avoid speed bumps?

Raised devices can affect passenger comfort, emergency response and large vehicles. Some roads therefore use speed tables, cushions or other traffic-calming measures designed to reduce these effects.

20. Toll road

A toll road is a road, motorway, bridge, tunnel or other route for which users must pay a charge. The toll may apply to all vehicles or only to particular vehicle categories, and the amount can depend on factors such as distance travelled, vehicle type, weight or emissions.

Tolls may be collected at toll booths, electronically or through a vignette or distance-based charging system. Drivers should check the applicable payment rules before using a toll road, especially when travelling in another country.

What is a toll road?

A toll road is a road or section of road for which a charge must be paid to use it. Tolls may also apply to particular bridges, tunnels or other road infrastructure.

How are road tolls paid?

Depending on the country, tolls may be paid at a toll booth, through an electronic toll system, vignette or distance-based charging system.

Do all vehicles pay the same toll?

Not necessarily. Toll rates can vary according to vehicle type, size, weight, emissions, distance travelled or the particular road being used.

21. Customs

Customs is the government authority responsible for controlling goods entering or leaving a country or customs territory. In road traffic, a customs checkpoint is a place where drivers may be required to stop so officers can inspect the vehicle, luggage, cargo and relevant documents.

Customs controls may take place at borders, ports, ferry terminals, airports or inland control locations. Drivers must follow all traffic signs, lane signals, barriers and instructions from customs officers. Declaration requirements depend on the countries involved and on the type, value, quantity and intended use of the goods being carried.

What is customs?

Customs is the government service that controls goods entering or leaving a country or customs territory, collects applicable duties and taxes, and enforces restrictions on prohibited or regulated goods.

What is a customs checkpoint?

A customs checkpoint is a control point where drivers and passengers may be required to stop, declare goods and present documents. Vehicles, luggage and cargo may be inspected in accordance with local law.

How can you recognise a customs checkpoint?

It may be indicated by signs displaying words such as Customs, Douane, Zoll or another local-language equivalent. Barriers, traffic lights, lane arrows and instructions from officers may also control access.

Must you stop at a customs sign?

Yes, when the sign or officer requires it. Reduce speed, enter the indicated lane and stop at the line, barrier or place shown.

Is customs the same as passport control?

No. Customs primarily controls goods, money and cargo. Passport or immigration control concerns people, identity documents and permission to enter or leave a territory. Both controls may take place at the same border facility.

Is a customs border always the same as a national border?

No. Several countries may form a customs union with no routine customs formalities between them. Some territories may also have a different customs status from the country to which they belong.

Does every border have a permanent customs checkpoint?

No. Some borders have permanent facilities, while others have mobile, temporary or selective controls. Borders within a customs union may have no routine customs checkpoint.

Can customs checks take place away from a border?

Yes. Depending on local law, checks may occur at ports, ferry terminals, airports, warehouses, inspection areas or inland road-control locations.

What should you do when approaching customs?

Reduce speed, observe the lane signs and be prepared to stop. Keep the required identification, vehicle, travel and goods documents accessible and follow the officers’ instructions.

Which documents may customs request?

Customs may request identification, vehicle documents, receipts, invoices, transport papers, customs declarations, permits or proof of ownership, depending on the journey and goods carried.

Which goods must be declared?

Goods exceeding duty-free allowances, commercial goods and certain restricted products may require a declaration. The applicable rules depend on the customs territory, journey, quantity, value and intended use.

What do red and green customs channels mean?

Where these channels are used, the red channel is generally for travellers who have goods to declare or need assistance. The green channel is for travellers who believe they have nothing that must be declared. Using the green channel does not prevent an inspection.

Can customs inspect your vehicle or luggage?

Yes, subject to local law. Officers may examine luggage, cargo spaces, vehicle compartments and accompanying documents to verify that customs rules are being followed.

Does duty-free mean that goods never need to be declared?

No. Duty-free allowances normally apply only within specified values, quantities and conditions. Restricted goods or quantities exceeding an allowance may still require declaration and payment.

Must cash be declared?

Many countries require travellers carrying cash or other monetary instruments above a specified amount to make a declaration. The threshold, definition of cash and procedure differ between customs territories.

Do personal belongings count as imported goods?

Ordinary personal belongings used during a journey are often admitted without duties, but newly purchased, high-value, commercial or restricted goods may be subject to special requirements.

What rules apply to commercial cargo?

Commercial goods normally require customs documentation and may be subject to duties, taxes, inspections, permits, origin rules and transit procedures. The driver must carry the documents required for the shipment.

What are restricted goods?

Restricted goods may include certain foods, plants, animals, medicines, weapons, cultural objects, protected species, counterfeit products and hazardous materials. Requirements vary by country.

What happens if goods are not declared?

Undeclared goods may be detained or seized, and the traveller may have to pay duties, taxes, fines or other penalties. Serious cases may lead to criminal proceedings.

Whose instructions should you follow at a customs checkpoint?

Follow the instructions of authorised customs, police and border officers, together with traffic lights, barriers, lane signals and road signs.

22. One-way traffic

One-way traffic means that vehicles on a road or carriageway may travel only in one designated direction. The permitted direction is normally indicated by traffic signs, lane arrows or road markings.

Some road users, such as cyclists or public-transport vehicles, may be allowed to travel in the opposite direction when signs expressly permit it. A one-way road does not by itself determine the speed limit, priority or parking rules.

Wikimedia.org • Frank Vincentz • CC BY-SA
What is a one-way road?

A one-way road is a road or carriageway on which vehicles may travel only in the designated direction.

How can you recognise one-way traffic?

One-way traffic is normally indicated by a one-way sign at the entrance and a no-entry sign at the opposite end. Lane arrows and road markings may provide additional guidance.

Is a one-way sign the same as a no-entry sign?

No. A one-way sign confirms the permitted direction of travel. A no-entry sign prohibits drivers from entering from the opposite direction.

Does one-way traffic apply to the entire road?

It may apply to an entire road, one carriageway, a particular lane or only a designated section. Drivers must follow the signs and markings applying to the part of the road they use.

Can a divided road have one-way traffic on each carriageway?

Yes. On a divided road, each carriageway normally carries traffic in one direction even though the road as a whole carries traffic in both directions.

May cyclists travel against one-way traffic?

Only when traffic signs or local law expressly permit contraflow cycling. Drivers should check supplementary signs and remain alert for cyclists approaching from the opposite direction.

May buses travel against one-way traffic?

Public-transport vehicles may use a contraflow lane where signs and road markings permit it. Other drivers may not use that lane unless they are also authorised.

Does a one-way road have its own speed limit?

No. The applicable speed depends on the country, road type, surrounding area and traffic signs.

Does one-way traffic change priority at intersections?

No. Drivers must continue to follow traffic lights, priority signs and the ordinary local priority rules.

Does traffic on a one-way road always have priority?

No. The one-way designation regulates direction of travel, not priority. Traffic entering or crossing the road may still have priority under signs or local law.

Which lane should you use on a one-way road?

Follow the local lane-positioning rules, lane arrows and destination signs. Drivers commonly keep to the normal side of the road unless overtaking, turning or choosing a marked lane.

Where should you position yourself before turning?

Use the lane or side indicated for the intended direction. On many one-way roads, drivers turning towards the opposite side of the road may position themselves closer to that side before turning.

May you overtake on a one-way road?

Overtaking may be permitted where there is sufficient space and no sign or rule prohibits it. The normal overtaking side and safety requirements continue to apply unless local law provides otherwise.

May you reverse on a one-way road?

A short reversing manoeuvre may be permitted where local law allows it and it can be completed safely. Drivers must not use reversing to travel along the road in the prohibited direction.

May you make a U-turn on a one-way road?

You may not turn around and continue against the permitted direction. A U-turn may also be prohibited by signs or general traffic law.

May you park on both sides of a one-way road?

This depends on local law, signs, markings and the available width. Some countries permit parking along either side, while others retain stricter positioning rules.

Can pedestrians come from both directions?

Yes. One-way traffic restrictions normally apply to vehicles using the carriageway, not to pedestrians using pavements or other pedestrian facilities.

Should you still check both directions?

Yes. Cyclists, buses, emergency vehicles or other authorised users may approach from the opposite direction. Drivers should check both directions before turning, crossing or opening a vehicle door.

What should you do if you enter a one-way road incorrectly?

Do not continue against traffic. Stop somewhere safe without creating additional danger and follow lawful directions to leave or correct the situation. Do not reverse blindly into an intersection.

How does one-way traffic end?

The restriction may end at an end sign, an intersection, a change in road design or a sign warning that two-way traffic resumes. Follow the local signs and road layout.

23. Quay

A quay is a constructed area beside a river, canal, harbour or other body of water, commonly used for loading, unloading, mooring vessels or providing waterside access. A road may run alongside the water or lead directly towards the quay edge.

In road traffic, a quay warning indicates a risk that a vehicle could leave the road and enter the water. Drivers should reduce speed, observe the road layout carefully and keep a safe distance from the waterside edge.

Warning for a quay. Warning for a steep descent of 20%. (Cenon-sur-Vienne, France)
Wikimedia.org • Lionel Allorge • CC BY-SA
What is a quay?

A quay is a constructed waterside platform or road area beside a river, canal, harbour or other navigable water. It may be used by ships, vehicles, workers, pedestrians and loading equipment.

What does a quay warning sign mean?

It warns that the road approaches or leads onto a quay, riverbank or waterside edge where a vehicle could enter the water.

Does the sign mean that the road ends at the water?

It may. The road may lead directly towards the water, turn sharply near it or continue alongside an insufficiently protected edge. Drivers must observe the actual road layout.

How should you approach a quay?

Reduce speed early, remain in full control and watch for the road edge, barriers, bends, workers, pedestrians and moving equipment. Avoid sudden steering or braking close to the water.

Is there a universal speed limit near a quay?

No. Drivers must follow the posted or general speed limit and reduce their speed further when the road is narrow, wet, poorly lit or close to an unprotected edge.

Does a quay warning sign impose a prohibition?

No. It normally warns of danger rather than prohibiting access. Additional signs, gates or local rules may restrict particular vehicles or activities.

Does the sign change priority?

No. Drivers must continue to follow traffic lights, priority signs and the normal priority rules.

May you stop or park on a quay?

This depends on local signs and regulations. Do not stop or park where the vehicle could create danger, obstruct traffic, interfere with loading operations or block emergency access.

Should you park close to the water’s edge?

Only in a clearly authorised and suitable place. Leave sufficient space from the edge, apply the parking brake securely and follow any wheel-positioning or local parking instructions.

May you overtake near a quay?

Overtaking may be legal, but it should be avoided when the road is narrow, visibility is limited or the manoeuvre would bring the vehicle close to the waterside edge.

Why can quay surfaces be slippery?

Water, algae, mud, ice, fuel, oil or material from loading operations may reduce grip. Painted markings, rails and metal surfaces may also become especially slippery when wet.

What other hazards may be present on a quay?

Drivers may encounter pedestrians, cyclists, dock workers, cranes, forklifts, railway tracks, mooring equipment, reversing trucks and unsecured edges.

Why should large vehicles take extra care?

Large vehicles need more space to turn and may have limited visibility close to the cab or trailer. Soft edges, narrow roads and nearby equipment can make manoeuvring more difficult.

May pedestrians walk on a quay?

Pedestrian access depends on local rules. Where pedestrians are permitted, drivers should expect them to move between vehicles, vessels, buildings and loading areas.

Should you reverse near a quay edge?

Reverse only when necessary and when the route is clearly visible. Use a guide where available and never rely solely on mirrors or cameras when the vehicle could approach the water.

What should you do in darkness or poor visibility?

Reduce speed, use the required lights and look carefully for reflectors, barriers, road edges and people. Water and dark surroundings can make the boundary of the road difficult to recognise.

What should you do if a barrier is open or missing?

Do not assume that the route is safe. Slow down, identify the road boundary and follow signs or instructions from authorised personnel.

What should you do if a vehicle enters the water?

Leave the vehicle as quickly and safely as possible, help passengers where possible and contact the emergency services. Do not re-enter the water or vehicle to recover belongings.

24. Slope

A slope is a section of road that rises or descends noticeably. A steep slope can affect vehicle speed, braking distance, traction, visibility and the ability of heavy or low-powered vehicles to maintain a steady speed.

Warning signs may indicate a steep ascent or dangerous descent and may show the gradient as a percentage. Drivers should adjust their speed early, select a suitable gear and remain prepared for slow vehicles, bends and changing road conditions.

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.

25. Bus lane

A bus lane is a traffic lane reserved primarily for buses or other authorised public-transport vehicles. It is intended to improve the reliability and flow of public transport by allowing authorised vehicles to avoid general traffic congestion.

Other road users, such as taxis, cyclists, motorcycles or vehicles carrying several occupants, may also be permitted when signs expressly allow them. The operating hours, permitted vehicles, direction of travel and rules for entering or crossing the lane depend on local traffic signs and regulations.

What is a bus lane?

A bus lane is a lane reserved primarily for buses or other authorised public-transport vehicles. Its purpose is to help public transport move efficiently through traffic.

How can you recognise a bus lane?

A bus lane may be identified by a bus-lane sign, lane markings, coloured surfacing or the word BUS painted on the road. The markings and colours differ between countries.

Is a bus lane the same as a bus-only road?

No. A bus lane forms part of a wider road arrangement, while a bus-only road may reserve the entire road for buses and other authorised users.

Who may use a bus lane?

Buses operating authorised or scheduled services may normally use it. Other vehicles may enter only when the traffic signs or local regulations expressly permit them.

May taxis use a bus lane?

This depends on local law and the signs displayed. Some bus lanes permit licensed taxis, while others are reserved exclusively for buses.

May cyclists use a bus lane?

Cyclists may use a bus lane where signs or local law permit them. They should remain alert for large vehicles, stops, passengers and buses moving towards the kerb.

May motorcycles use a bus lane?

Only where motorcycles are expressly permitted. Permission may apply to all motorcycles, particular times or specific bus lanes.

Can a bus lane operate only at certain times?

Yes. A sign may show days or hours during which the restriction applies. Outside those periods, the lane may become available to general traffic, subject to the local rules.

Does a bus lane have a special speed limit?

Not necessarily. The normal road or posted speed limit generally applies unless a separate restriction is displayed.

May ordinary vehicles enter a bus lane to turn?

Some countries allow drivers to enter a bus lane shortly before a junction to make a turn. Drivers must follow the lane markings and enter only at the point where local rules permit it.

May you cross a bus lane?

Usually, where necessary and permitted. A driver may need to cross it at an intersection or to enter or leave a property, parking area or side road. The driver must check carefully for buses, cyclists and other authorised users.

May you use a bus lane to pass congestion?

No. An unauthorised driver may not use the bus lane simply to overtake a queue or reach the front of traffic.

May you stop or park in a bus lane?

Stopping and parking are normally prohibited unless a sign or marked bay expressly permits them. A stopped vehicle can obstruct buses and force authorised lane users into general traffic.

Do buses always have priority when leaving a stop?

Not universally. Some countries require drivers to allow a signalling bus to leave a stop, particularly inside built-up areas. Elsewhere, ordinary merging rules apply.

Does a bus lane change priority at an intersection?

No. Traffic lights, priority signs and the ordinary intersection rules continue to apply unless special public-transport signals indicate otherwise.

Can a bus lane run against the direction of general traffic?

Yes. A contraflow bus lane may carry authorised vehicles in the opposite direction from nearby general traffic. Drivers and pedestrians should check both directions before crossing.

What do special bus traffic lights mean?

Some countries use separate lights or symbols for public-transport vehicles. Only drivers authorised to use that lane should follow those signals, while other traffic follows its own lights.

What should you check before crossing a bus lane?

Check mirrors and blind spots and look for buses, taxis, cyclists, motorcycles or other authorised vehicles. Their lane may be moving even when general traffic is stationary.

How does a bus lane end?

It may end at a sign, a change in road markings, an intersection or the end of its stated operating period. Drivers should follow the lane arrows and merge safely where required.
