交通ルールアイスランド

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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

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

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.

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

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.

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

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.

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

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.

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

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

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

A give-way sign requires drivers to allow traffic with priority to proceed first. The driver must slow down and stop when necessary.

It is commonly an inverted triangular sign with a red border and a light-coloured centre. In some countries, it is called a yield sign.

No. You must stop only when necessary to give way or obtain a sufficiently clear view. You may continue slowly when the road is clearly free.

Giving way means allowing another road user to continue without being forced to brake, accelerate, stop or change direction because of your movement.

Stop before the give-way line where one is provided. Without a line, stop before entering the intersection or priority road at a position where you can observe traffic safely.

You may move beyond the line only when this does not interfere with traffic that has priority. Where visibility is limited, first slow or stop at the line and then move forward cautiously.

A stop sign always requires a complete stop. A give-way sign permits the driver to continue without stopping when the road is clearly free and it is safe to proceed.

Only when slowing down is sufficient to let all priority traffic proceed safely. If another road user would be hindered, the driver must slow further or stop.

Give way to traffic travelling on the road being entered or crossed and to any pedestrians, cyclists or other road users who have priority under the applicable rules.

No. Check every direction from which lawful traffic may approach, including cycle paths, one-way roads with authorised contraflow traffic and separate carriageways.

The sign determines priority at the particular location. The priority arrangement at later intersections may be different unless the road is separately identified as a priority road.

No. You may proceed only when it is safe. Another driver’s hesitation or courtesy does not remove your responsibility to avoid danger.

Yes. Each driver must observe the road and make an individual decision. You may not follow another vehicle through without checking that the way remains clear.

Normally, yes. Cyclists are generally treated as drivers and must obey the sign unless a supplementary sign or local rule provides otherwise.

Yes. Some countries use supplementary signs or path-specific signs to require cyclists to give way while other traffic follows a different priority arrangement.

No. It regulates priority rather than speed. Drivers must still approach slowly enough to observe traffic and stop when necessary.

No. Drivers must still obey traffic lights, lane arrows, mandatory-direction signs and turning prohibitions.

Many roundabout entrances have give-way signs requiring entering traffic to yield to vehicles already circulating. Drivers must follow the actual signs because roundabout priority rules differ between countries.

Functioning traffic lights commonly take precedence over priority signs controlling the same movement. The give-way sign may apply again when the lights are switched off or flashing, depending on local law.

Yes. Instructions from an authorised traffic officer normally take precedence over traffic signs and ordinary priority rules.

Reduce speed substantially and stop when necessary. Move forward cautiously only after giving way and checking that the road can be entered without danger.

A priority road is a road on which drivers normally have priority over traffic entering from intersecting side roads.

It is normally indicated by a priority-road sign at or near its beginning. A corresponding end sign indicates where its continuing priority status stops.

Normally, yes, while the priority-road designation remains in force. Drivers must still observe traffic lights, authorised officers and any signs applying at a particular intersection.

Not necessarily. A priority road commonly continues across successive intersections until an end sign or another legally defined change in priority.

Side roads are commonly controlled by give-way or stop signs, but sign placement and legal requirements differ between countries.

Where the priority-road signs apply, drivers entering from intersecting side roads must normally give way regardless of whether they approach from the left or right.

No. A priority-road sign normally creates continuing priority across several intersections. Another sign may grant priority only at the next intersection.

No. The priority route may turn at an intersection. A supplementary diagram may show which branch retains priority.

Priority does not remove the duty to signal. Use the direction indicators whenever following or leaving the priority route involves a change of direction or lateral movement.

No. Approach every intersection at a safe speed and remain prepared for another road user to fail to give way.

No. The applicable general, zonal or posted speed limit remains in force.

Functioning traffic lights normally control the intersection instead of the priority signs. Local rules determine what applies when the lights are switched off or flashing.

Yes. Instructions from an authorised traffic officer normally take precedence over traffic signs and ordinary priority rules.

Yes, where the applicable crossing rules give them priority. Priority over side-road traffic does not remove duties towards pedestrians.

You must still give way to oncoming traffic, pedestrians, cyclists and other road users where the normal turning rules require it.

Cyclists using the road or a continuing bike path may have priority over entering or turning traffic, depending on signs, markings and local law.

Not automatically. Roundabout priority is determined by its own signs, signals and local rules.

Priority-road status does not itself permit or prohibit overtaking. Drivers must follow the ordinary overtaking rules, markings and visibility requirements.

This depends on local law and signs. Some countries prohibit parking on priority roads outside built-up areas, while other parking rules may apply inside towns and cities.

No. A driver entering the road from a property, parking place or other off-road location normally performs a manoeuvre and must give way to road users already present.

No. Do not enter when congestion would force you to stop inside the intersection and obstruct crossing traffic.

Its continuing priority normally ends at an end-of-priority-road sign. Drivers must then follow the signs or ordinary priority rule applying at the next intersection.

In right-hand traffic countries, overtaking normally takes place on the left. In left-hand traffic countries, it normally takes place on the right. National rules can provide exceptions in particular situations.

Make sure there is sufficient visibility and space, check mirrors and blind spots, ensure that nobody behind has already started overtaking and confirm that you can safely return to your normal position after passing.

Do not overtake where signs or road markings prohibit it or where visibility, approaching traffic, intersections, crossings, bends, hills or other conditions make the manoeuvre unsafe.

It warns that animals may enter or cross the road in the area ahead.

Depending on the symbol and local conditions, it may refer to deer, cattle, horses, sheep, goats, wild boar or other animals.

It is commonly a triangular warning sign displaying the silhouette of an animal. The species shown may indicate the type of animal most likely to be encountered.

No. It indicates an increased likelihood of animals crossing, not that animals will be present every time.

No. The normal posted or general speed limit remains applicable, but drivers must reduce speed when necessary to react safely.

No automatic priority is created by the warning sign. Drivers must nevertheless avoid danger and allow animals already on the road to pass safely.

Reduce speed, increase your following distance and scan the road, verges, fields and vegetation for movement or reflected eyes.

Animal activity is often greater around dawn, dusk and darkness, although animals may cross at any time.

Many animals travel in groups. When one animal crosses, others may follow immediately from the same direction.

Avoid unnecessary horn use or engine revving because it may frighten an animal and make its movement less predictable. Use a warning only when reasonably necessary to prevent danger.

Use the appropriate lights without dazzling other road users. When an animal is visible, reduce speed and avoid relying on full beam to make it move away.

Slow down smoothly, stop when necessary and allow it enough time and space to leave. Avoid sudden acceleration or aggressive steering.

Avoid an uncontrolled swerve that could cause a collision with another vehicle, tree, barrier, cyclist or pedestrian. Brake firmly while maintaining control and steer only when a safe escape path is clearly available.

Pass only when the animals and their handlers have sufficient space. Drive slowly, avoid noise and be prepared for an animal to change direction unexpectedly.

Reduce speed, leave a large lateral distance and pass quietly. Avoid sounding the horn, accelerating sharply or passing when oncoming traffic prevents sufficient clearance.

Follow lawful instructions from an authorised person and cooperate with handlers controlling animals on or across the road.

The warning sign does not necessarily prohibit overtaking, but overtaking should be avoided when animals, limited visibility or approaching traffic make the manoeuvre unsafe.

Maintain enough following distance to see beyond the vehicle ahead. Be prepared for it to brake suddenly when an animal enters the road.

Reduce speed, keep both hands firmly in control and avoid sudden movements. Animals may react unexpectedly to quiet or fast-approaching two-wheeled vehicles.

Stop safely, activate the hazard warning lights and check for injured people. Contact the emergency services or police when necessary and do not approach a wounded wild animal, which may defend itself.

Normally not. Keep a safe distance and allow the police, wildlife authorities or an animal-rescue service to handle it.

Yes. Drivers remain responsible for observing the road and adjusting their speed even where no animal warning sign is displayed.

A road curve is a section where the road changes direction to the left or right.

It may be indicated by a triangular warning sign showing a curved line. The symbol normally indicates whether the first curve turns left or right.

A double curve consists of two curves in opposite directions. The warning sign normally shows the direction of the first curve.

Yes. A double-curve symbol may also warn of a longer sequence of successive curves. A supplementary panel may indicate the length of the winding section.

No. It normally warns of danger rather than setting a numerical limit. Drivers must still reduce speed when the permitted maximum would be unsafe.

Reduce speed before entering the curve, while the vehicle is travelling straight and has maximum stability.

No. Harsh braking in a curve can reduce stability and grip. Complete most braking beforehand and use smooth adjustments where necessary.

Maintain a controlled speed through the curve. Accelerate smoothly only when the exit becomes visible and the vehicle is stable.

Look towards the path you intend to follow and the visible exit of the curve. Continue checking the road surface, lane position and nearby traffic.

Yes. Do not cross the centre line or cut across another lane, even when this would make the curve appear easier to negotiate.

Buildings, vegetation, slopes, barriers and the road alignment may hide oncoming traffic, cyclists, pedestrians, stopped vehicles or debris.

Choose a speed that allows you to remain in your lane and stop within the distance you can see to be clear. The safe speed may be far below the legal maximum.

An advisory speed is a recommended safe speed for negotiating the curve under suitable conditions. It is not necessarily the legal maximum speed.

They reduce tyre grip and increase the risk of skidding. Reduce speed earlier, use smooth controls and leave additional distance from other vehicles.

Avoid sudden braking or steering. Reduce speed smoothly and follow a clear path without entering another traffic lane.

Do not overtake when visibility is insufficient to see approaching traffic and complete the manoeuvre safely. Local law, signs and continuous road markings may also prohibit overtaking.

Only where it is permitted and the vehicle remains clearly visible. Stopping or parking in a poorly visible curve may create a serious hazard and is often prohibited.

No. Leave enough distance to react if the vehicle ahead brakes for a hidden obstruction or a sharper part of the curve.

Motorcycles require grip for both cornering and braking. Riders should reduce speed before the curve, choose a stable line and avoid painted markings, gravel and slippery surfaces.

A trailer may sway, track closer to the inside of the curve or become unstable when speed and steering inputs are excessive. Enter slowly and steer smoothly.

Buses and trucks may move closer to lane boundaries because of their length and width. Other drivers should avoid travelling beside them through a tight curve.

Reduce speed, move safely towards your side of the road and avoid a sudden manoeuvre that could cause another collision. Sound a warning only when reasonably necessary.

No. Drivers must assess every curve and adapt their speed even when no warning sign is displayed.

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

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

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.

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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.

A driving licence is an official authorisation to drive specified categories of motor vehicle.

The terms may refer to the same document, depending on the country. Some countries use permit specifically for learners or temporary authorisations.

A provisional or learner licence allows a person to practise driving under specified restrictions before obtaining a full licence.

A full licence is issued after the holder has completed the required tests or training. Restrictions may still apply because of age, vehicle type, medical fitness or licence codes.

No. Driving licences are divided into categories for motorcycles, cars, buses, trucks, trailers and other vehicles.

A licence category identifies the type and size of vehicle the holder is authorised to drive.

Yes. Holding a licence for one category does not normally authorise driving a vehicle belonging to another category.

Yes. Codes may restrict the holder to an automatic transmission, corrective lenses, an adapted vehicle or another specified condition.

In some countries, passing the test in an automatic vehicle restricts the holder to automatic vehicles until an additional test or procedure is completed.

Usually, yes. The document, individual categories or medical authorisation may have expiry dates and require renewal.

No. The licence and the category required for the vehicle must remain valid.

This depends on local law. Many countries require drivers to carry the original licence and present it to an authorised officer when requested.

Not normally. A photograph, scan or photocopy is not generally a substitute for the original document unless an official digital-licence system is legally recognised.

No. It proves driving authorisation, not ownership, registration or insurance.

Requirements may include a theory test, eyesight test, practical driving test, medical examination or compulsory training.

No. Minimum ages differ between countries and vehicle categories.

Only where the provisional-licence system permits independent driving. Other learners must be accompanied by an approved supervisor or instructor.

Often not. Provisional and learner licences are frequently valid only in the country or region that issued them.

An international driving permit is a standardised translation of a valid national licence intended to help authorities interpret it abroad.

No. It normally has legal value only when presented together with the valid national driving licence on which it is based.

This depends on the destination, length of stay, residence status and agreements between the countries concerned. An exchange or international permit may be required.

Some countries exchange recognised foreign licences without new tests, while others require theory, practical or medical examinations.

Yes. A medical condition may require an assessment, shorter validity period, adapted vehicle or licence restriction.

This depends on local law. Drivers remain responsible for ensuring that they are physically and mentally fit to drive safely.

Often, yes. Drivers of trucks, buses, taxis or vehicles used commercially may require professional competence, medical examinations or periodic training.

The holder may not drive during the suspension period, even if the physical document remains in their possession.

Disqualification is a legal prohibition on driving, usually imposed by a court or competent authority for a specified period or until conditions are fulfilled.

Report it where required and apply for a replacement through the competent licensing authority. Do not continue driving when local law requires the original document to be carried.

Request a replacement when the document is unreadable, damaged or no longer allows the holder to be identified reliably.

This depends on the country and whether the address appears on the licence. Drivers must follow the local notification and replacement procedure.

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.

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.

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

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.

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

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.

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.

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

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.

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.

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.

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

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.

A general danger warning sign indicates that there is a hazard ahead that is not represented by a more specific warning sign in the local traffic-sign system.

It can be used for unusual or uncommon hazards for which no dedicated warning symbol exists. The nature of the danger may be explained by an additional panel, symbol or message.

Look for a supplementary panel, text or symbol accompanying the warning sign. It may describe the hazard or provide information needed to understand the warning.

Increase your attention, observe the road and surroundings carefully and adapt your speed where necessary so that you can respond safely to the hazard.

Not normally. A warning sign alerts road users to danger rather than establishing a numerical speed limit. A separate speed-limit sign may be provided where a specific maximum speed is required.

It is used when the traffic-sign system does not contain a specific symbol that accurately represents the particular hazard.

Yes. A general warning sign may be used for either a temporary or continuing hazard, depending on local signing rules and the circumstances.

Yes. Depending on the country's traffic-sign system, an additional panel may indicate the distance to the hazard, the length of the dangerous section or other useful information.

No. A danger warning sign does not by itself change the priority rules. Drivers must continue to follow traffic lights, priority signs and the normal right-of-way rules.

Not necessarily. The sign normally warns of a hazard ahead of the sign, and the dangerous situation may extend over a section of road. Supplementary information may indicate its location or length.

A blind summit is the crest of a hill where the driver's view of the road beyond the summit is restricted.

Vehicles, pedestrians, cyclists, bends or obstacles may be hidden beyond the crest, leaving drivers less time to react.

Generally, no when visibility is insufficient. Drivers should avoid entering the path of opposing traffic unless they have a clear view and overtaking is permitted by the applicable traffic rules.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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

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

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.

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.

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.

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

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.

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

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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

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.

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

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.

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.

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

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

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

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.

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.

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

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

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

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

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

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

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.

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

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.

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.

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.

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.

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

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

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

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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

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

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.

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.

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

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.

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.

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.

A road code is the body of traffic rules and regulations governing how road users must behave on public roads.

A road code can regulate subjects such as priority, speed, overtaking, turning, parking, traffic signals, road signs and road markings, as well as the responsibilities of different road users.

No. Although many traffic rules and signs are similar internationally, each country establishes its own traffic legislation and may apply different rules, signs, speed limits and requirements.
