Traffic rulesNew Zealand

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A stop sign requires a driver to come to a complete stop and give way before proceeding.

A stop sign is commonly a red octagonal sign displaying the word STOP. Some countries use another legally recognised design, so drivers must learn the signs used locally.

Yes. The obligation to stop applies even when the road appears completely clear.

A complete stop means that the vehicle has ceased moving entirely. Merely slowing down or allowing the vehicle to continue rolling does not satisfy the requirement.

Stop before the stop line where one is provided. Without a line, stop at the legally prescribed position before entering the intersection, crossing or priority road.

No. The required first stop must be made before the line. If visibility is limited, move forward cautiously after stopping and stop again where necessary before proceeding.

Yes. Each driver must make an individual complete stop. Following another vehicle through without stopping is not permitted.

No. After stopping, you must continue to give way to all road users who have priority.

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

A stop sign always requires a complete stop. A give-way sign requires the driver to yield but normally allows continued movement when the road is clearly free.

Yes. After stopping and giving way, you may turn in any direction permitted by signs, signals, lane arrows and road markings.

This depends entirely on local law and traffic signs. A stop sign does not by itself permit a turn against a red light.

No. It imposes a stopping and yielding obligation. The normal posted or general speed limit remains applicable before and after the intersection.

In many countries, cyclists are drivers and must stop unless a specific sign or local rule provides an exception.

The order in which drivers may proceed depends on local rules, commonly involving arrival order, vehicle position and turning direction. Drivers should communicate cautiously and never assume another driver will yield.

Apply the local priority rule and proceed only when the intentions of the other driver are clear. Avoid forcing the other vehicle to brake or change direction.

Where functioning traffic lights control the same movement, they commonly take precedence over the stop sign. Local rules determine what applies when the lights are switched off or flashing.

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

Yes. A correctly placed temporary stop sign at roadworks, an event or another temporary traffic arrangement must be obeyed.

If you recognise that a stop sign applies, reduce speed and obey it. Report damaged, obscured or missing signs to the responsible road authority where appropriate.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A road narrowing is a section where the usable width of the road becomes smaller. Traffic may have less space to pass, merge or travel beside other road users.

It may be indicated by a triangular warning sign showing the road edges moving closer together. The symbol may show narrowing on both sides, the left side or the right side.

A road may narrow because of a bridge, tunnel, barrier, traffic-calming measure, roadworks, parked vehicles, landslide, damaged road edge or reduction in the number of lanes.

No. It normally warns of danger rather than setting a numerical speed limit. Drivers must still reduce speed when necessary to pass safely.

Not by itself. Priority may be established by separate signs, signals or local rules. Without them, drivers should approach cautiously and cooperate.

In many countries, the driver whose side is obstructed must give way to approaching traffic. The precise rule depends on local law and any priority signs displayed.

Neither direction necessarily has automatic priority. Drivers should reduce speed, assess who can pass safely and avoid entering when doing so would block approaching traffic.

One sign may require you to give way to oncoming traffic, while the corresponding sign may indicate that you have priority. Drivers must still avoid entering when the passage is already occupied or blocked.

No. Priority is not an obligation to proceed. Slow down or stop when another vehicle is already in the narrow section or when continuing would create danger.

Allow it enough room to leave the narrow section. Do not enter if the available width is insufficient for both vehicles to pass safely.

Check mirrors, reduce speed smoothly and observe oncoming traffic, cyclists, pedestrians and vehicles beside you. Be prepared to stop or merge.

Use an indicator when you must change lanes or move laterally. Merely following a lane that bends with the road may not require a signal under local law.

Check the adjacent lane, signal and merge safely according to the local merging rules. Do not force another driver to brake or leave the road.

Zipper merging means that vehicles from an ending or blocked lane merge alternately with vehicles in the continuing lane, usually immediately before the narrowing during congestion.

Where zipper merging applies, continue using both lanes and merge alternately near the narrowing. In free-flowing traffic, change lanes safely when a suitable gap is available.

A narrowing sign does not always prohibit overtaking, but overtaking should be avoided when there is insufficient width, visibility or distance to complete the manoeuvre safely.

Wait behind the cyclist when the required passing distance cannot be maintained. Do not squeeze past or force the cyclist towards a kerb, barrier or damaged road edge.

Large vehicles may need additional width and may cross lane or centre markings where legally permitted. Other drivers should leave sufficient space and avoid passing alongside them in the narrowing.

Yes. Pavements or verges may also become narrow or blocked. Drivers should expect pedestrians or wheelchair users to enter the carriageway to pass an obstruction.

Only where it is permitted and enough width remains for traffic to pass safely. Never stop or park where the vehicle would create danger, obstruct visibility or prevent other vehicles from passing.

Follow temporary signs, signals, barriers and instructions from authorised workers. Temporary traffic controls may replace the normal priority or lane arrangement.

Reduce speed further, increase the following distance and be prepared for a stopped vehicle beyond the narrowing. Use the required lights without dazzling approaching road users.

A pedestrian crossing is a designated place for pedestrians to cross a road. It may be controlled by traffic lights or operate without signals.

It may be indicated by white road markings, traffic signs, flashing lights, pedestrian signals or a raised crossing. Its appearance varies between countries.

A zebra crossing is a type of pedestrian crossing marked by broad contrasting stripes or rectangles. Not every pedestrian crossing uses this design.

Not universally. Priority depends on local law, traffic signals and whether the pedestrian is already crossing or clearly preparing to cross.

This depends on local law. In many countries, drivers must give way when a pedestrian is clearly intending or preparing to enter the crossing.

Reduce speed, observe both sides of the road and be prepared to stop. Pay particular attention to children, older people and persons with limited mobility.

No. Do not enter when traffic ahead may force you to stop on the crossing and block pedestrians.

Stop before the crossing or before the applicable stop line. Leave the crossing completely clear.

Overtaking may be prohibited, particularly when another vehicle has stopped or slowed for the crossing. Even where no specific prohibition applies, overtaking is unsafe when pedestrians may be hidden from view.

Normally not. Stopping or parking on or immediately before a crossing can obstruct pedestrians and hide them from approaching drivers.

Not by itself. Drivers must respect the applicable speed limit and reduce their speed further when necessary to stop safely.

Yes. Drivers and pedestrians must follow the signals applying to them. Drivers must still allow pedestrians who lawfully started crossing to finish safely.

No. Pedestrians must wait when the pedestrian signal prohibits them from entering the road.

A pedestrian who entered lawfully should continue at a normal pace. Drivers must allow the crossing to be completed safely.

This depends on local law. In many countries, a person riding a bicycle is treated as a driver and does not receive pedestrian priority. A cyclist walking beside the bicycle is normally treated as a pedestrian.

Not automatically. A separate cycle crossing, cycle path or combined crossing may be indicated by additional markings or signs.

Some countries require pedestrians to use a crossing when one is located within a specified distance. Other countries allow crossing elsewhere when it can be done safely.

No. Pedestrians should cross without unnecessary delay and should not obstruct traffic by stopping or lingering on the road.

The raised surface itself does not necessarily determine priority. Drivers and pedestrians must follow the crossing markings, signs, signals and local rules.

Check for pedestrians approaching from both sides and give way where required. Turning drivers should not focus only on motor traffic.

Observe approaching traffic, make sure drivers have sufficient time to react and cross carefully. Priority does not remove the need to avoid stepping into the path of a vehicle that cannot stop safely.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

It requires drivers to follow the direction or one of the directions shown by the arrow or arrows.

It is commonly a blue circular sign with one or more white arrows. Colours and designs may differ in some countries.

It normally means that drivers must continue straight ahead and may not turn in another direction at that location.

It normally requires drivers to turn or proceed in the direction shown by the arrow.

Drivers may choose one of the displayed directions. Any direction not shown is prohibited.

It requires drivers to pass the traffic island, barrier, roadworks equipment or other obstruction on the side indicated by the arrow.

No. A mandatory-direction sign prescribes a movement at a particular location. A one-way sign indicates the permitted direction along a road or carriageway.

No. A mandatory sign states which direction must be followed, while a prohibition sign states which movement is forbidden. Both may produce a similar practical result.

No. Drivers must follow the applicable general, zonal or posted speed limit and reduce speed when necessary to complete the required movement safely.

No. You must still obey traffic lights, priority signs and the ordinary rules concerning oncoming traffic, pedestrians, cyclists and other road users.

It normally applies at the sign, intersection or obstacle associated with it. An advance sign may indicate that the obligation begins farther ahead.

Yes. When it is positioned above a particular lane or clearly associated with that lane, it normally applies only to traffic using that lane.

Yes. Lane arrows may require drivers to use a particular lane and follow one of the directions displayed within that lane.

Yes, when the required movement involves turning or changing position and local law requires signalling. The sign does not replace the obligation to indicate.

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

Not when doing so would conflict with the mandatory direction or another prohibition. Drivers must follow the permitted route shown by the signs and markings.

No. Reversing must not be used to evade a mandatory direction. Continue along a lawful route and turn around later where permitted.

Cyclists are normally treated as drivers and must obey the sign unless a supplementary panel or local rule expressly exempts them.

Yes. Supplementary signs may exempt or separately regulate cyclists, public transport or other specified categories where local law permits this.

Do not enter a closed or unsafe route. Stop where safe and follow temporary signs, traffic lights or instructions from authorised personnel.

Not normally. Traffic lights determine when traffic may proceed, while the mandatory-direction sign determines which movement is permitted.

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

Yes. Properly placed temporary signs at roadworks, incidents or events must be obeyed.

It requires vehicles carrying specified dangerous goods to follow a designated route suitable for their cargo and any applicable tunnel restrictions.

The obligation is normally completed after the driver has followed the required direction at the intersection or passed the obstacle on the indicated side.

A turn prohibition prevents drivers from making a particular turn or change of direction indicated by a traffic sign.

It is commonly a circular sign with a red border showing a crossed or barred turning arrow. The arrow indicates the movement that is prohibited.

It prohibits drivers from turning left at the location or intersection to which the sign applies.

It prohibits drivers from turning right at the location or intersection to which the sign applies.

It prohibits drivers from turning around to travel in the opposite direction.

No. A prohibition sign identifies a movement that may not be made. A mandatory-direction sign identifies the direction or directions that must be followed.

No. A turn prohibition prevents a particular approach from turning into a road. A no-entry sign prohibits vehicles from entering the road from the direction where it is displayed.

No. A one-way rule controls the permitted direction along a road. A turn prohibition controls a particular movement at or near an intersection.

It may apply at the sign, at the next intersection or throughout a stated section. Drivers must follow the sign design and the rules of the country concerned.

Yes. An advance sign or supplementary distance panel may warn drivers that the prohibited turn is farther ahead.

Yes. A sign positioned above or clearly associated with one lane may apply only to drivers using that lane.

Yes. Drivers must choose the correct lane and follow one of the directions displayed by its legally binding arrows.

No. A green light permits traffic to proceed, but drivers must still respect turn prohibitions, lane arrows and other regulatory signs.

No. Drivers making another permitted movement must still follow traffic lights, priority signs and the ordinary rules concerning pedestrians, cyclists and other vehicles.

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

Yes, where local law requires it. Signal early enough to communicate your intention and stop signalling after completing the movement.

No. An indicator communicates an intention but cannot authorise a movement prohibited by a traffic sign.

Yes. A supplementary sign may allow cyclists or other specified road users to make a turn that remains prohibited for general traffic.

Public transport, taxis or other authorised vehicles may be exempted where a supplementary sign or local rule expressly permits the movement.

Not universally. Some countries treat these as separate prohibitions. Drivers must check whether a separate no-U-turn sign or general rule applies.

This depends on the exact legal scope of the sign. A sign applying specifically to the next intersection may not regulate an earlier property entrance, but another sign or road marking may still prohibit the movement.

No. Do not reverse through traffic or into an intersection to evade the sign. Continue along a permitted route and change direction later where it is legal and safe.

Follow the movement permitted from that lane. Do not turn suddenly across another lane or ignore the sign; continue and choose another legal route.

Yes. Properly placed temporary signs near roadworks, incidents or events must be obeyed.

Yes. Follow instructions from an authorised traffic officer even when they differ from the displayed turn prohibition.

A school area is a road or group of roads near a school where drivers should expect large numbers of children, pedestrians, cyclists and stopping vehicles.

It may be identified by school warning signs, speed-zone signs, flashing lights, road markings, coloured surfacing or traffic-calming measures. The signs differ between countries.

No. Special school-area rules normally apply only where signs, signals or local legislation establish them.

There is no universal school-area speed limit. The applicable limit depends on the country, region, signs and whether a variable restriction is active.

Some limits apply permanently, while others apply only during displayed times or when flashing or variable signs are active. Drivers must observe the actual sign arrangement.

Yes, when necessary. The displayed speed is a maximum. Children, congestion, poor visibility or vehicles stopping near the school may require a much lower speed.

Children may have difficulty judging speed and distance, may be hidden by parked vehicles and may enter the road unexpectedly.

Reduce speed early, increase your observation and be prepared for children crossing, cyclists changing direction, vehicle doors opening and cars stopping suddenly.

No. Priority depends on crossings, traffic lights, authorised crossing supervisors and local rules. Drivers must nevertheless take exceptional care to avoid endangering children.

Yes. Drivers and other road users must follow lawful instructions given by an authorised person controlling traffic for children.

This depends on local pedestrian rules. Drivers should remain prepared for children to cross unexpectedly, even where they are required to use a nearby crossing.

Not by itself. A school warning sign alerts drivers to children but does not normally create the legal effect of a pedestrian crossing.

No. Traffic lights, priority signs and the ordinary intersection rules remain applicable unless another traffic arrangement provides otherwise.

Overtaking may be restricted by signs or local law. Even where it is permitted, drivers should not overtake when children, crossings, limited visibility or stopped vehicles make the manoeuvre unsafe.

Only where stopping is permitted and can be completed safely. Do not stop on a crossing, pavement, bike path, bus stop or another prohibited or dangerous location.

Follow the parking signs and markings. Do not block entrances, pavements, bike paths, crossings, visibility or access for buses and emergency vehicles.

It blocks traffic and visibility and may force children to walk between moving vehicles or enter the road from behind an obstruction.

Expect children to enter or leave the vehicle and possibly cross the road. Reduce speed and follow any special warning lights, signs or local school-bus rules.

Normally, yes. They must follow the applicable road, bike-path, speed and priority rules. Drivers should expect inexperienced young cyclists.

No. A school area normally remains open to traffic under special caution or speed rules. A school street temporarily restricts or excludes motor traffic during specified periods.

Not universally. A school area may form part of a Zone 30, use another speed limit or have a variable restriction that applies only at particular times.

They normally end at an end sign, at the end of the stated time period or when the variable signal is no longer active. The surrounding road rules then apply.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.
