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.

A road chevron is a V-shaped or arrow-shaped marker used to guide drivers through a curve or another sharp change in road direction.

It is normally displayed on a rectangular board using strongly contrasting colours. Several chevrons may be placed in sequence around a curve.

The point of the chevron indicates the direction in which the road continues. A chevron pointing left guides traffic through a left curve, while one pointing right guides traffic through a right curve.

They are generally placed along the outside of a curve, facing approaching traffic so that drivers can clearly see the road alignment.

A series of chevrons visually traces the curve and helps drivers judge its direction, length and changing alignment.

No. A curve-warning sign normally warns drivers before the curve. Chevron boards are usually positioned within or around the curve to guide drivers through it.

No. It guides drivers through the change in direction but does not normally introduce a numerical speed limit.

Not by itself. A separate advisory-speed or speed-limit sign may indicate an appropriate or legally required speed.

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

It normally indicates that the curve requires additional visual guidance. Drivers should expect a noticeable or potentially sharp change in direction.

Not directly. The number and spacing depend on the length, radius and design of the curve and on the road authority’s signing standards.

Not necessarily. Larger boards may be used where approach speeds are higher or where greater visibility is needed.

Reduce speed before the curve, observe the direction of the boards and remain within your traffic lane.

No. Complete most braking before entering the curve and use smooth steering, braking and acceleration while following it.

No. The boards normally mark the outside edge of the curve. Follow the road around them rather than steering towards them.

No. Remain within your lane and do not enter the path of oncoming traffic.

The chevrons do not automatically prohibit overtaking, but overtaking is unsafe when the curve restricts visibility or available road width.

Reflective material makes the boards easier to see in darkness and poor weather when illuminated by vehicle headlights.

Yes. Some high-risk curves use illuminated or flashing chevrons to make the change in direction more conspicuous.

Yes. Their colours and design vary between countries, but contrasting colours are used to make the direction clearly visible.

Reduce speed before the curve, choose a stable path and look through the turn. Do not focus exclusively on the chevrons or allow the motorcycle to cross the centre line while leaning.

No. Drivers must assess every curve and select a safe speed whether or not chevron boards are installed.

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.

Roadworks are construction, maintenance, repair or inspection activities carried out on or beside a road.

They may be indicated by a roadworks warning sign, cones, barriers, temporary markings, flashing lights, machinery or workers.

No, not by itself. A separate temporary or permanent speed-limit sign establishes the legal maximum speed.

Yes, when necessary. Narrow lanes, workers, machinery, poor surfaces, congestion or limited visibility may require a substantially lower speed.

Yes. Correctly installed temporary signs must be obeyed for as long as they are in force.

Follow the temporary markings that guide traffic through the works. Local law determines how they take priority over older permanent markings.

Yes. Stop at the line or signal when required and do not proceed until the applicable light permits it.

Obey instructions from workers or controllers who are legally authorised to regulate traffic. Their signals may temporarily replace the ordinary traffic arrangement.

Observe the signs and lane arrows, check mirrors and blind spots and merge safely into the continuing lane.

Zipper merging means that vehicles in an ending or blocked lane merge alternately with vehicles in the continuing lane near the narrowing during congested traffic.

This depends on local law and traffic conditions. Where zipper merging applies during congestion, use both lanes and merge near the narrowing. In flowing traffic, change lanes when a safe gap is available.

Without another traffic control, the driver whose route is obstructed commonly has to yield before moving into the path of approaching or adjacent traffic.

Yes. Temporary signals may allow only one direction at a time through a narrow section.

No. Do not enter a narrow section, intersection or temporary crossing when congestion may leave you stopped inside it.

No. Do not move, pass around or ignore traffic-control equipment unless an authorised person instructs you to do so.

Only when signs and markings permit it and sufficient width and visibility remain. Overtaking is often unsafe in narrow or shifted lanes.

Only where temporary and permanent signs permit it. Do not obstruct workers, machinery, emergency access or temporary pedestrian and cycle routes.

Expect workers to enter the road, machinery to move or reverse and vehicles to leave the worksite. Reduce speed and leave generous space.

Follow the signed temporary cycle route or lane. Check surrounding traffic carefully before leaving a closed or obstructed bike path.

Use the designated temporary walkway or crossing and follow barriers, signs, signals and instructions from authorised personnel.

Traffic may brake suddenly because of queues, lane changes, machinery, debris or changing signals. Additional distance provides more time to react.

Move to the safest available location where possible, activate the hazard warning lights and contact assistance. Avoid standing in a live or narrow traffic lane.

Yes. Rules concerning safe speed, following distance, signalling, priority and vulnerable road users continue to apply unless a lawful temporary arrangement changes them.

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.

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.

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.

Road markings are lines, symbols, arrows or words placed on the road surface to regulate, guide or provide information to road users.

They can separate traffic lanes, indicate stopping or priority points, guide traffic movements and mark crossings or reserved areas.

No. Many markings are internationally similar, but their colours, designs and exact legal meanings can vary between 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.

A road location marker is a numbered reference point identifying a measured position along a particular road or route.

A kilometre marker indicates the number of kilometres measured from an established starting point on the road.

A hectometre marker identifies a position at intervals of 100 metres. One kilometre contains ten hectometres.

It normally identifies a point approximately 14 kilometres and 700 metres from the route’s reference origin.

No. It normally measures the position along the road from a fixed reference origin rather than the remaining distance to a destination.

It begins at a reference point chosen for that road, such as the start of the route, a border, an administrative boundary or another officially defined origin.

No. It increases in the officially defined direction of the route. Drivers travelling in the opposite direction may see the values decrease.

It may appear as a numbered roadside post, small sign, plate, marker attached to a barrier or numbers painted beside the carriageway.

Many countries use kilometre markers, while countries using imperial measurements may use mile markers. Designs and intervals differ.

They are intended to represent 100-metre intervals, but their physical placement and permitted tolerances depend on the road authority and local conditions.

Give the road number, marker value, direction of travel and nearest junction or landmark where possible.

The same kilometre value may occur on many different roads. The road number identifies which route the marker belongs to.

Divided roads have separate carriageways. Reporting the direction helps emergency services approach the correct side without making a long diversion.

Yes. Reporting the nearest marker can help breakdown and emergency services identify the affected road section more accurately.

Yes. The marker can help road authorities locate an obstruction, damaged barrier, animal, collision or other dangerous situation.

Normally not. It is a reference or identification device rather than a regulatory sign.

No. The applicable speed comes from general traffic rules and regulatory speed signs.

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

No. Passing a kilometre or hectometre marker does not normally begin or end a traffic regulation.

Yes. Road authorities use reference points to locate signs, barriers, bridges, defects, works and other infrastructure precisely.

Coordinates can be useful, but a road reference marker may be easier for road operators and emergency services to connect with the correct carriageway and road section.

Use the nearest visible marker together with the road number, direction, junctions and other identifiable features.

No. Do not stop in a live lane or another prohibited location. A passenger may note the marker, or the driver may read it after stopping somewhere safe during an actual emergency.

Normally not. Temporary traffic routes may move traffic away from the marker’s usual position, but the official road reference system generally remains unchanged.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

An international border is the legal boundary between two countries.

It may be identified by a country-name sign, national or regional symbols, flags, border posts, customs facilities or passport-control signs.

No. Borders may be marked differently, and some minor roads or open-border areas may have only a small identification sign or boundary marker.

Not normally. Stop only when required by traffic lights, barriers, officers, customs signs, passport controls or another instruction.

The new country’s traffic laws apply from the international boundary, not merely from the next town or major intersection.

No. The rules change because you have entered another country. The sign identifies that change of jurisdiction.

Yes. Where neighbouring countries use different driving sides, a specially designed road arrangement guides traffic safely from one side to the other.

Yes. The destination country may have different general limits for motorways, built-up areas, rural roads and particular vehicle categories.

No. Drivers must learn the destination country’s general limits and obey any regulatory signs displayed after crossing.

Yes. Colours, symbols, shapes and road-marking conventions may differ, even when neighbouring countries follow similar international standards.

Yes. Requirements concerning safety vests, warning triangles, winter tyres, lights, toll equipment or environmental stickers may differ between countries.

Depending on the journey, drivers may need a passport or identity card, driving licence, vehicle-registration document, insurance evidence, visa or customs documents.

No. Border or immigration control concerns people and travel documents. Customs control principally concerns goods, cargo, money and applicable duties or restrictions.

Yes. Both may operate at the same border facility even though they perform different legal functions.

No. Countries participating in an open-border area may normally cross internal borders without routine checks, although temporary controls may still be introduced.

No. Countries within a customs union may allow goods to move across their internal borders without ordinary customs duties or routine customs formalities.

No. Police, customs and other authorities may still conduct lawful checks, enforce national rules and temporarily control the border where permitted.

Only where local law permits it. External or controlled borders may have to be crossed through an authorised border-crossing point during its operating hours.

Yes. Closures or restrictions may result from security measures, emergencies, severe weather, roadworks or administrative decisions.

Yes. A crossing may restrict heavy vehicles, dangerous goods, agricultural traffic, pedestrians or cyclists because of road design or border-control facilities.

Yes. Commercial goods, restricted products, goods exceeding personal allowances and certain amounts of cash may require declaration.

They may. The destination country may use toll roads, vignettes, distance-based charges, low-emission zones or other payment systems.

No. Navigation information may not include current border controls, vehicle restrictions or document requirements. Follow official signs and instructions.

Check the destination and transit countries’ traffic rules, required documents, insurance, vehicle equipment, tolls and border or customs requirements.

Yes. Follow lawful instructions from authorised border, police and customs officers, even when they temporarily differ from the normal traffic arrangement.

Cycling routes are commonly indicated by direction signs, bicycle symbols, route numbers, colours or destination markers. The design of the signs and route-numbering system varies between countries and regions.

Usually not. A cycling-route sign normally provides direction or route guidance rather than imposing a mandatory direction. However, separate mandatory traffic signs may require cyclists to use a particular cycle path or direction.

No. A cycle path is a specific part of a road or separate path intended for cyclists under local traffic rules. A cycling route is an entire itinerary and may include cycle paths, ordinary roads, cycle streets and other types of infrastructure.

Not necessarily. Many cycling routes use roads and paths that are also open to motor vehicles, pedestrians or other road users. Access is determined by the signs and rules applying to each individual section.

Not automatically. Being on a designated cycling route does not normally change the priority rules. Cyclists must continue to obey traffic lights, give-way and stop signs, crossing rules and other applicable traffic regulations.

No. A route may combine dedicated cycle infrastructure with quiet streets, shared roads, rural roads and other suitable connections. The quality and level of separation from motor traffic can therefore change along the route.

Yes. A cycling route may cross or temporarily follow busy roads. At such locations, cyclists must follow the crossing, priority and traffic-light rules indicated by local signs and markings.

Yes, unless access is restricted by separate traffic signs or regulations. A cycling-route designation by itself does not normally prohibit cars, motorcycles or other vehicles from using an otherwise public road.

Yes. Cycling routes may be designed for daily travel, tourism or recreation. Some form part of regional, national or international networks and may be identified by route names or numbers.

Always follow the official traffic signs, signals and road markings. A route marker provides navigation and does not override a prohibition, mandatory direction, road closure or other traffic regulation.

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.

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.

Disabled parking spaces are intended for eligible people who hold a valid disabled parking permit or card. The exact eligibility requirements and permit system depend on the country.

Generally no. Disabled parking permits are normally personal and may only be used when the permit holder is driving or travelling in the vehicle.

No. A permit may provide access to reserved spaces or exemptions from certain parking restrictions, but rules concerning parking charges and time limits vary between countries and local authorities.

Traffic management is the organised control and guidance of traffic using signs, signals, road markings, lane controls, speed restrictions, diversions and other measures.

Traffic management is used to improve safety, control traffic flow and reduce disruption. It can also protect road workers, pedestrians, cyclists and emergency services.

Common methods include traffic lights, road signs, road markings, variable-message signs, lane-control signals, temporary barriers, speed restrictions and diversions. Authorised persons may also direct traffic.

Yes. Temporary or variable speed-limit signs may impose a different maximum speed because of congestion, roadworks, weather, incidents or other conditions. Drivers must follow the limit currently displayed.

Yes. Lane-control signals, temporary signs or road markings may close lanes, move traffic into different lanes or require drivers to change lane. Follow the current signs and markings rather than the normal road layout.

Move into an open lane safely and in good time, following any arrows, signs and local merging rules. Never continue along a lane that is clearly indicated as closed.

Yes. Properly authorised temporary signs used for roadworks, incidents or other traffic-management measures must be obeyed in the same way as other official traffic signs.

Follow the directions of the authorised person. In many countries, these directions take precedence over traffic lights, road signs or the normal traffic rules.

Roadworks may use temporary speed limits, lane closures, barriers, temporary markings, traffic lights and diversions. Road users should reduce speed where necessary and carefully follow the temporary route.

Yes. Temporary or permanent traffic arrangements should account for pedestrians and cyclists as well as motor vehicles. They may be provided with separate routes, crossings, signals or diversions where necessary.

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 road surface warning indicates that the surface ahead may be uneven, damaged or otherwise capable of affecting the safe movement of vehicles.

Depending on the country, it may warn of bumps, depressions, potholes, broken pavement, uneven repairs or other surface irregularities.

Reduce speed where necessary, increase your awareness of the road ahead and be prepared for changes in the vehicle's stability or direction.

Not normally. A warning sign alerts drivers to a hazard rather than establishing a numerical speed limit. A separate speed-limit sign may be used where a particular maximum speed is required.

Where slowing is necessary, it is generally safer to reduce speed before reaching the irregular surface rather than braking sharply while travelling over it.

A severe surface irregularity can affect tyre contact, steering, braking and vehicle stability. It can also damage tyres, wheels or suspension components.

Yes. Two-wheeled vehicles can be particularly sensitive to potholes, ridges and other irregularities because these hazards may disturb their balance or alter their direction suddenly.

No. An uneven-road warning concerns the physical condition or shape of the road surface. A slippery-road warning concerns reduced tyre grip caused by the surface or conditions such as water, ice, mud or other substances.

Yes. A supplementary sign may indicate the distance to the hazard or the length of the affected section, depending on the country's traffic-sign system.

Yes, when conditions require it. Additional distance provides more time to react if the vehicle ahead slows suddenly to avoid a pothole or other surface defect.

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 charging station is a location where electric vehicles can be connected to an electricity supply to recharge their batteries. A station may contain one or several individual charging points.

Charging stations are intended for vehicles that can be externally charged, such as battery-electric vehicles and plug-in hybrid vehicles. The exact vehicle categories permitted may be indicated by local signs or operator conditions.

Not necessarily. A space beside a charger may be reserved for electric vehicles or vehicles that are charging. Drivers must check the signs and markings before parking there.

Not where the parking space is officially reserved for electric vehicles. An ordinary parking space located near a charger may be different, so the applicable signs and markings determine who may park there.

This depends on the local traffic and parking rules. Many charging spaces require the vehicle to be connected to the charger, even if the vehicle itself is electric.

Charging may be free or subject to payment. The price and payment method are determined by the charging operator, while separate parking charges may also apply.

Yes. Traffic signs, parking regulations or charging conditions may establish a maximum duration to encourage drivers to move their vehicles and make the charger available to others.

Follow the local parking rules and charging conditions. Some locations require vehicles to leave after charging or impose additional fees or time limits when the charging session has ended.

No. A charging station does not allow a driver to ignore no-parking rules, reserved spaces, time limits or other traffic regulations. The vehicle must still be legally parked.

No. Charging stations can provide different charging powers. Some are intended for longer parking periods, while high-power chargers can recharge compatible vehicles much more quickly.
