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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

It prohibits vehicles whose total height exceeds the displayed value from continuing beyond the sign.

It is commonly a circular regulatory sign showing a height in metres, feet or another local unit between vertical arrows.

The height includes the vehicle, its load and any attached equipment, such as roof boxes, bicycles, machinery, antennas or raised loading equipment.

Yes. Every part of a vehicle combination must fit beneath the restriction, including the towing vehicle, trailer and load.

Not necessarily. Road authorities may display a lower value than the measured clearance to provide a safety margin.

The legal wording commonly prohibits vehicles higher than the displayed value, but drivers should not attempt to pass without a practical safety margin. Measurement errors, movement and road conditions can reduce the available clearance.

Loading, tyre pressure, suspension settings, raised equipment, replacement tyres and road movement can alter the vehicle’s total height.

Yes. The vehicle may rise or lower depending on its suspension mode, speed and load. Use the maximum travelling height when planning the route.

Yes. An arched bridge, tunnel roof or overhead structure may provide different clearance in each lane. Follow lane-specific signs and markings.

Yes. Clearance may be lower near the edge of an arch or where the road slopes sideways. Remain within the authorised marked path.

Yes. A new road surface can raise the road level and reduce the space beneath a bridge or structure.

Yes. Material on the road can raise the vehicle or restrict the usable route. Flooding may also conceal the road surface or another hazard.

They are common at bridges, tunnels, car parks, loading areas, gateways, railway structures and roads with overhead equipment.

It is normally a prohibition. A vehicle that exceeds the displayed height may not pass.

No. The applicable road or posted speed limit remains in force, although drivers should approach cautiously.

No. Traffic lights, priority signs and ordinary priority rules remain applicable.

Yes. An advance sign may show the restriction and the distance to it so that high vehicles can choose another route.

Do not continue. Stop where safe and follow the signed diversion or another suitable route. Do not reverse into traffic without assistance.

No. Navigation may contain outdated or incomplete vehicle restrictions. Traffic signs and the actual road conditions always take precedence.

Yes. Drivers of trucks, buses, motorhomes and vehicles carrying roof loads should know and, where useful, display the vehicle’s maximum travelling height inside the cab.

Stop before the restriction in a safe place and verify the vehicle’s height. Choose another route when safe clearance cannot be confirmed.

Only when signs and markings permit it and the manoeuvre can be completed safely. Do not cross a closed lane, continuous line or opposing traffic merely to gain clearance.

Only in a safe place and when the equipment can be secured correctly afterwards. Never stop beneath the structure or in a live lane to alter the vehicle.

Stop immediately where safe, activate the hazard warning lights and contact the emergency services or police. Do not continue because the vehicle, load or structure may be unstable.

No, when damage may have occurred. Keep away from the structure and follow instructions from the police, road authority or railway operator.

It prohibits vehicles or vehicle combinations whose relevant mass exceeds the value displayed on the sign.

It is commonly a circular regulatory sign showing a mass in tonnes, kilograms or another local unit.

It is normally a prohibition. A vehicle exceeding the displayed limit may not continue beyond the sign.

Actual loaded mass is the weight of the vehicle as it is currently travelling, including the vehicle itself, its load, driver, passengers and other relevant equipment.

Maximum authorised mass is the highest total mass at which the vehicle is legally approved to operate. It is normally recorded in the vehicle documents.

No. A lightly loaded vehicle may have an actual mass below its maximum authorised mass. A restriction may legally refer to either measurement, depending on the sign and local law.

Yes. Cargo, passengers, fuel, equipment and other carried items may all contribute to the vehicle’s actual loaded mass.

Where the restriction concerns actual loaded mass, the driver and other occupants are normally included.

This depends on the wording of the restriction. It may apply to each vehicle separately or to the combined mass of the complete vehicle combination.

An axle-weight limit restricts the amount of mass carried by one axle or axle group rather than the total mass of the vehicle.

A vehicle may comply with the total weight limit while too much of its load is concentrated over one axle, creating excessive stress on the road or bridge.

They are often used at bridges, weak roads, historic centres, tunnels, temporary structures and roads unsuitable for heavy traffic.

Not necessarily. The displayed legal limit may include engineering and safety margins and should not be interpreted as the structure’s exact failure point.

A sign normally prohibits vehicles exceeding the displayed value. The driver must still be certain that the relevant mass does not exceed it.

The most reliable method is to use an authorised or suitable weighbridge. Vehicle documents alone normally show approved limits rather than the vehicle’s current loaded mass.

An estimate may help with planning, but it must include the vehicle, fuel, occupants, equipment, load and trailer. A weighbridge is preferable when the remaining margin is small.

No. Moving cargo within the vehicle does not change its total mass, but it can change the load carried by each axle.

Yes, when done lawfully and safely. The vehicle may continue only after its relevant mass complies and the remaining load is properly secured.

Yes. Temporary restrictions may protect a damaged bridge, weakened road, roadworks structure or road affected by flooding or thawing.

Yes. Lane-specific signs may direct heavier vehicles towards a lane or structure designed to carry them.

Yes. Advance signs may give the distance to the restriction or indicate a diversion so affected vehicles can choose another route.

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

No. Traffic lights, priority signs and ordinary priority rules remain applicable.

Do not continue. Stop where safe and follow a signed diversion or another route suitable for the vehicle’s mass.

No. Navigation information may be incomplete or outdated. Traffic signs and official restrictions always take precedence.

Only when reversing is lawful and can be completed safely. Use assistance where necessary, particularly with a long or heavy vehicle combination.

The vehicle may damage the road or structure and may be stopped, fined, unloaded or prohibited from continuing under local law.

It warns that vehicle speeds may be measured or enforced on the road ahead or throughout a specified section.

No. A speed-limit sign establishes the maximum legal speed. A radar sign only warns that compliance with an applicable limit may be monitored.

Check the most recent speed-limit sign, variable sign, speed-zone sign or general limit applying to the road and vehicle category.

No. It does not normally change the existing limit. Drivers must nevertheless travel more slowly when traffic, visibility, weather or road conditions require it.

It may announce a permanent camera, a mobile-control area or a section where enforcement can occur. The exact meaning depends on the country and sign design.

No. Drivers should never rely on assumptions about whether equipment is operating and should respect the speed limit at all times.

A fixed speed camera is permanently installed at a particular location and measures the speed of passing vehicles.

A mobile speed camera is temporarily positioned in a police vehicle, trailer, roadside unit or another approved location.

Lidar uses laser pulses to measure the speed and position of vehicles. It may be used by police officers or in temporary automatic installations.

Average-speed enforcement records a vehicle at two or more points and calculates its average speed across the controlled section.

No. Average-speed enforcement considers the travel time across the complete measured section rather than speed at only one point.

Yes. Some systems monitor vehicle speed and whether a vehicle passes a red traffic signal.

No. Some authorities announce speed cameras, while others permit enforcement without advance warning. The rules differ between countries and regions.

Yes. The absence of a warning sign does not normally prevent police or authorised authorities from carrying out a lawful speed check.

The applicable limit remains a maximum rather than a target. Drivers must reduce speed whenever travelling at that limit would be unsafe.

No. Check your speed and reduce it smoothly when necessary. Sudden braking can cause a rear-end collision.

Only while remaining within the applicable limit and driving safely. The restriction may continue, and another camera or average-speed section may follow.

No. Passing a camera or radar sign does not end the applicable speed restriction.

A radar speed display measures an approaching vehicle and shows its current speed, sometimes with a colour, message or smiley symbol.

Not necessarily. Many displays are preventive devices intended to make drivers aware of their speed and may collect anonymous traffic statistics without issuing penalties.

No. The roadside display is generally informational. Drivers remain responsible for observing the vehicle’s speedometer and the legal speed limit.

Yes. The technical ability to measure a motorcycle and the method used to identify it depend on the enforcement equipment.

Yes. Modern systems may measure vehicles in one or more lanes and may distinguish between traffic directions or vehicle categories.

Yes. Heavy vehicles, buses, trailers or other vehicle categories may be subject to lower limits than passenger cars on the same road.

Release the accelerator and reduce speed smoothly and safely. Do not brake harshly or make an abrupt lane change.

It means that drivers travelling on the indicated road have priority over traffic entering from intersecting roads at the next junction.

No. Priority at the next junction applies to one particular junction. A priority road normally keeps its priority across several junction until its status ends.

No. The term main road may describe a larger, busier or more important road, but legal priority is determined by traffic signs, signals and local rules.

It may be indicated by a priority-junction sign showing a thick line for the priority route and thinner lines for the roads that must give way.

Yes. On signs using a junction diagram, the thicker line normally represents the road followed by traffic with priority.

No. The priority route may turn left or right. A diagram or supplementary panel may show which branch retains priority.

They commonly face a give-way or stop sign, requiring them to yield to traffic on the priority route.

Not when legally placed signs establish another priority arrangement at that junction. Drivers must follow the actual signs rather than the ordinary default rule.

No. After passing the indicated junction, the priority arrangement at the next junction must be determined separately.

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

No. Priority is not an obligation to continue. Slow down or stop whenever proceeding would create danger.

No. Do not enter when congestion is likely to leave your vehicle stopped inside the junction and obstructing other traffic.

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

No. Drivers must still yield to pedestrians where crossings, traffic signals or turning rules require it.

It regulates priority between traffic approaching the junction, but drivers must still respect continuing bike paths, cycle crossings and turning rules.

Yes, when following the route involves a change of direction and local law requires signalling. Priority does not remove the obligation to indicate.

No. An indicator communicates your intended movement but does not allow you to endanger or obstruct another road user.

Normally, yes. Priority over side-road traffic does not automatically give a left-turning driver priority over lawful oncoming traffic.

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

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

No. Overtaking remains subject to the ordinary rules, visibility, road markings and any separate prohibition signs.

No. The ordinary stopping and parking rules and any local signs or markings remain applicable.

The special priority indicated by the sign has been completed. At later junctions, follow the signs, signals or default priority rule applying there.

A traffic lights warning alerts drivers that traffic signals are located ahead.

It may be used where traffic lights are unexpected, difficult to see sufficiently early or located on a road where advance warning improves safety.

Remain alert, reduce speed when necessary and be prepared to stop at the traffic lights or behind waiting traffic.

Pedestrian lights are traffic signals that indicate when pedestrians may begin crossing a road.

They commonly display a red standing person and a green walking person. Their design may vary between countries.

It means that pedestrians must not begin crossing.

It means that pedestrians may begin crossing, provided they still observe the road and cross without unnecessary delay.

No. Turning vehicles, emergency vehicles or traffic following another authorised signal may still cross the pedestrian route. Pedestrians should remain attentive.

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

Its meaning varies between countries. It commonly means that pedestrians must not begin crossing, while those already on the road should finish without delay.

A countdown may show approximately how much time remains before the signal changes. It does not remove the duty to cross cautiously.

Begin only when there is enough time to cross safely and without stopping unnecessarily on the road. Waiting for the next green phase may be safer.

Continue crossing at a normal pace towards the nearest safe side. Do not turn back suddenly, stop unnecessarily or run into another traffic stream.

Yes. Drivers should allow pedestrians who entered lawfully to complete the crossing safely, even when vehicle traffic receives permission to proceed.

Some signal systems permit turning vehicles and pedestrians at the same time. Turning drivers must give way where required and must not endanger pedestrians.

It is a signal phase during which conflicting vehicle movements are stopped so pedestrians can cross without permitted traffic turning across their route.

It is a phase in which pedestrians may cross several or all approaches while vehicle traffic is stopped. Diagonal crossing is permitted only when the signals and markings allow it.

They may indicate that the same pedestrian signal applies simultaneously to several crossing directions. The exact meaning depends on local law.

Check that approaching and turning vehicles are stopping and that the route is clear. A green signal does not make a collision impossible.

Yes. They should proceed at a normal pace and should not linger, stop unnecessarily or obstruct traffic on the crossing.

Pedestrians may have to follow the traffic lights controlling vehicles, an authorised officer or the ordinary pedestrian-crossing rules.

A push button normally registers a request for a pedestrian crossing phase. Pressing it does not itself permit crossing; pedestrians must wait for the appropriate signal.

Normally not. Once the request has been registered, additional presses usually have no effect.

Audible signals use sounds to help pedestrians with visual impairments identify when crossing is permitted or when the signal is changing.

Tactile signals may use a vibrating button, rotating cone or raised markings to provide crossing information to pedestrians with visual impairments.

Not normally. A cyclist riding a bicycle must follow the applicable cycle or vehicle signal unless a combined pedestrian-and-cycle signal applies.

A person walking beside a bicycle is normally treated as a pedestrian and follows the pedestrian signal.

They display pedestrian and bicycle symbols and apply to the road users indicated by those symbols.

No. Instructions from an authorised traffic controller normally take precedence over pedestrian lights.

Cross only according to the functioning vehicle signals, priority rules and instructions from authorised personnel. Proceed cautiously and take approaching traffic into account.

Left-hand traffic means that vehicles normally drive on the left side of a two-way road. Traffic approaching from the opposite direction therefore passes on the driver's right.

Vehicles normally overtake on the right, although exceptions can apply depending on the road layout and national traffic rules.

Most vehicles designed for left-hand traffic have the steering wheel on the right-hand side. However, vehicles with the steering wheel on the opposite side can also be legally used in many countries.

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.

De-restriction means that a previously imposed local traffic restriction has ended.

No. When a local restriction ends, the normal speed limit and other traffic rules applicable to that road still remain in force.

Depending on the country, it may be indicated by an end-of-restriction sign, a crossed-out restriction sign or another sign introducing a new rule.

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

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

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

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

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

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

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

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

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

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

A no-parking sign prohibits leaving a vehicle parked in the area or along the section of road to which the restriction applies. The exact legal definition of parking and the extent of the prohibition vary between countries.

No. A no-parking restriction commonly still permits certain brief stops, such as picking up or dropping off passengers or loading or unloading goods. A no-stopping restriction is stricter and generally prohibits voluntary stopping as well as parking.

Remaining inside the vehicle does not necessarily mean that it is not parked. If the vehicle remains stationary beyond what local law permits as a brief stop, it may legally be considered parked even when the driver stays inside.

Often yes, if stopping is permitted and the vehicle remains there only as long as reasonably necessary for passengers to get in or out. Local rules may impose stricter restrictions at particular locations.

In many countries, genuine loading or unloading is treated as stopping rather than parking and may therefore be permitted. The vehicle should remain there only for the time reasonably necessary for the activity.

This depends on the country's signing rules. The restriction may continue to the next intersection, an end sign, a stated distance or the end of a designated zone. Supplementary arrows or distance panels may indicate its exact extent.

Usually a roadside no-parking sign applies only to the side of the road on which it is placed, unless it forms part of a zonal restriction or local signs indicate otherwise.

Yes. A supplementary panel may restrict the prohibition to particular hours, days or periods. Outside those periods, parking may be permitted if no other rule prohibits it.

Yes. Additional signs or symbols may make a parking restriction applicable to particular vehicle categories, such as heavy vehicles, motorcycles or other specified vehicles.

Only if parking is otherwise legal. The end of a specific no-parking restriction does not override general parking prohibitions near crossings, intersections, driveways, traffic signs or other protected locations.

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 U-turn is a manoeuvre used to reverse a vehicle's direction so that it continues along the road in the opposite direction.

Check traffic in all relevant directions, mirrors and blind spots, and look for pedestrians, cyclists and other road users. Make sure there is sufficient visibility and space and that the manoeuvre is permitted.

No. U-turns may be prohibited by traffic signs or road rules and should never be attempted where visibility, road layout or traffic conditions make the manoeuvre unsafe.

A hostel is an accommodation establishment that usually provides affordable overnight stays, often with shared rooms or communal facilities.

A hostel generally offers simpler and more communal accommodation, while hotels more commonly provide private rooms and a broader range of services.

Yes. Some countries use tourist or accommodation signs to direct travellers toward hostels or youth hostels.

A tourist attraction is a place that visitors travel to because of its cultural, historical, natural, recreational or entertainment value.

Examples include monuments, castles, museums, scenic locations, cultural sites, amusement parks and recreational destinations.

Yes. Many countries use tourist or direction signs to guide travellers toward important attractions and places of interest.

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 cyclist is a person who rides and controls a bicycle.

Yes. Cyclists are road users and must follow the traffic rules, signs and signals that apply to them.

This depends on local rules. Cyclists may be required to use a cycle path or designated cycling facility, while in other situations they may ride on the carriageway.

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 taxi is a vehicle used to transport passengers for payment, normally providing journeys requested by individual customers.

Depending on the local system, taxis may be available at taxi stands, airports, railway stations, on the street or through telephone and app-based booking services.

Yes. Taxi services are generally subject to licensing and operating requirements, although the exact rules concerning vehicles, drivers, fares and permitted operating areas vary between jurisdictions.

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.
