176. Pedestrian
A pedestrian is a person travelling on foot along or across a road, street, path or other public space. Depending on local traffic law, people pushing bicycles, wheelchairs, prams or certain other small devices may also be treated as pedestrians.
Pedestrians normally use pavements, sidewalks, footpaths and pedestrian areas where these are available. When crossing a road or walking where no suitable pedestrian facility exists, they must follow the applicable crossing rules, traffic lights and other local traffic regulations.

What is a pedestrian?
A pedestrian is primarily a person travelling on foot. Local traffic laws may also treat people pushing bicycles, wheelchairs, prams or certain other devices as pedestrians.
Where should pedestrians normally walk?
Pedestrians should normally use pavements, sidewalks, footpaths or other areas provided for pedestrians. Where these are unavailable, local rules determine where pedestrians may walk on or beside the road.
Which side of the road should pedestrians walk on when there is no pavement?
This depends on the country's traffic rules. Many countries require or recommend pedestrians to face approaching traffic, but the exact rule varies.
Where should pedestrians cross a road?
Use a pedestrian crossing, traffic-light-controlled crossing or other designated crossing where required or reasonably available. Where crossing elsewhere is permitted, choose a location with good visibility and cross carefully.
Do pedestrians always have priority at a pedestrian crossing?
The exact priority rule varies between countries. Drivers are commonly required to give way to pedestrians using or entering designated crossings, but pedestrians must still obey traffic lights and avoid entering the road dangerously.
Must pedestrians obey traffic lights?
Yes. Where pedestrian signals are provided, pedestrians must follow their indications and should not enter the roadway while the signal prohibits crossing.
Is someone pushing a bicycle a pedestrian?
In many traffic systems, a person who dismounts and walks beside a bicycle is treated as a pedestrian. The precise legal classification depends on local law.
Can pedestrians use a cycle path?
This depends on the road layout and local rules. Pedestrians may sometimes use a cycle path when no suitable pedestrian facility is available, but they must not unnecessarily obstruct cyclists or other authorised users.
Do turning vehicles have to watch for pedestrians?
Yes. Drivers turning into another road must watch carefully for pedestrians crossing the road they are entering and give way where required by local traffic law.
What should pedestrians do before crossing a road?
Check carefully for approaching traffic from all relevant directions, make sure there is sufficient time and distance to cross safely, and continue to observe traffic while crossing.
177. Cyclist
A cyclist is a person who rides and controls a bicycle. Cyclists are road users and, in many countries, bicycles are legally treated as vehicles, meaning cyclists must follow many of the same traffic rules that apply to other drivers together with rules specifically intended for cycling.
Cyclists should use designated cycling facilities where required, obey traffic signs and signals and ride in a predictable and safe manner. The exact rules governing road position, priority, equipment and permitted cycling areas vary between countries.

What is a cyclist?
A cyclist is a person who rides and controls a bicycle.
Is a cyclist considered a road user?
Yes. Cyclists are road users and must follow the traffic rules, signs and signals that apply to them.
Where should cyclists ride?
This depends on local rules. Cyclists may be required to use a cycle path or designated cycling facility, while in other situations they may ride on the carriageway.
178. Moped
A moped is a lightweight motor vehicle, usually with two or three wheels, whose power, engine capacity or maximum design speed is limited by law. Mopeds generally occupy a legal category between bicycles and motorcycles, although their exact classification varies between countries.
Special rules may apply concerning the minimum riding age, driving licence, helmet, registration, insurance, maximum speed and use of cycle paths or roadways. Riders must therefore follow the classification and traffic regulations applying in the country where they are travelling.

What is a moped?
A moped is a lightweight motor vehicle whose engine power, capacity or maximum design speed is restricted by law. The precise technical definition differs between countries.
Is a moped the same as a motorcycle?
No. Mopeds normally have lower maximum speeds and power than motorcycles and are classified separately under traffic and licensing laws.
Is an electric moped still a moped?
Yes, potentially. A vehicle can be legally classified as a moped whether its motor is electric or uses an internal-combustion engine. Classification depends on factors such as design speed and power.
Do you need a driving licence for a moped?
This depends on the country and moped category. Some low-speed mopeds may be ridden without a licence, while faster mopeds commonly require a dedicated moped licence or another qualifying driving licence.
Do moped riders have to wear a helmet?
Helmet requirements vary between countries, but an approved protective helmet is compulsory for moped riders in many jurisdictions. Passengers may also be required to wear one.
Can a moped use a cycle path?
This depends on the moped category, road speed limit and local signs. Some low-speed mopeds may be required to use cycle paths, while faster mopeds may be required or permitted to use the roadway.
Can a moped carry a passenger?
Only where the vehicle is designed and legally approved to carry a passenger and the rider satisfies any minimum-age or licensing requirements.
Does a moped need a licence plate?
Many countries require mopeds to be registered and display a registration plate. Requirements vary according to vehicle category and national law.
Does a moped need insurance?
Compulsory third-party liability insurance is required for mopeds in many countries. The exact insurance requirements depend on the vehicle classification and national legislation.
Can a moped use a motorway?
Mopeds are generally prohibited from motorways and other high-speed controlled-access roads because their maximum design speed is too low and the road may specifically exclude them.
179. Motorcycle
A motorcycle is a motor-powered vehicle with two wheels, with or without a sidecar. Motorcycles include many different types and sizes of vehicles designed for road travel, recreation, touring or other purposes.
Motorcyclists should maintain full control of the motorcycle, obey the applicable traffic rules and use appropriate protective equipment. Licensing, helmet, equipment and road-use requirements vary between countries.
Wikimedia.org • CC0
What is a motorcycle?
A motorcycle is a powered two-wheeled vehicle, which may also be equipped with a sidecar.
Is a motorcycle the same as a moped?
No. Traffic laws generally distinguish motorcycles from mopeds according to technical characteristics such as power, engine capacity or maximum speed.
What protective equipment should a motorcyclist use?
Motorcyclists should use an approved helmet and suitable protective clothing. The exact mandatory equipment depends on the country's traffic laws.
180. Car
A car is a motor vehicle primarily designed to transport a small number of people and their luggage on roads. Cars may be powered by petrol, diesel, electricity, hydrogen or a combination of different energy sources.
Drivers must comply with the applicable requirements concerning the driving licence, vehicle registration, insurance, technical condition, seat belts and passenger safety. Speed limits, equipment requirements, road access and other traffic rules vary between countries, so drivers must follow the local traffic signs and regulations.
Wikimedia.org • Lothar Spurzem • CC BY-SA
What is a car?
A car is a motor vehicle primarily designed to carry a relatively small number of passengers and their luggage on roads.
Is a car the same as a motor vehicle?
No. A car is a type of motor vehicle. The broader category of motor vehicles can also include motorcycles, buses, trucks, mopeds and other powered vehicles, depending on local legal definitions.
Do you need a driving licence to drive a car?
Yes. A driver must normally hold a valid driving licence for the vehicle category concerned. The licence categories and minimum ages vary between countries.
Does a car need to be registered?
Yes, normally. Cars used on public roads generally have to be registered with the competent authority and display the required registration plate or plates.
Does a car need insurance?
Most countries require at least third-party liability insurance before a car may be used on public roads. Additional insurance may be optional.
Must people in a car wear seat belts?
Where seat belts are fitted, drivers and passengers are generally required to wear them correctly. Exact requirements and exemptions vary between countries.
Do children need a special restraint in a car?
Yes, in many countries. Children below specified age, height or weight thresholds must be transported in an appropriate approved child-restraint system.
How many passengers can a car carry?
A car must not carry more people than it is designed and legally approved to transport. Passengers should use the designated seating positions and required restraint systems.
Can a car tow a trailer?
Yes, if the vehicle and licence permit it. Maximum trailer masses, combination masses and licence requirements depend on the vehicle and local regulations.
Can every car use a motorway?
Most ordinary cars can use motorways, but they must satisfy the applicable vehicle, speed and access requirements. Certain unusually slow or restricted vehicles may be prohibited.
181. Truck
A truck is a motor vehicle designed primarily for transporting goods. Trucks range from relatively small delivery vehicles to large heavy goods vehicles and articulated combinations used for long-distance freight transport.
Because trucks are generally larger, heavier and slower to manoeuvre than passenger cars, they require more space for turning and braking and often have larger blind spots. Specific speed, lane-use, overtaking and access rules may apply depending on the vehicle's weight and the country.
Wikimedia.org • Marc Mongenet • CC BY-SA
What is a truck?
A truck is a motor vehicle designed primarily for transporting goods.
Are all trucks considered heavy goods vehicles?
No. Trucks can include lighter goods vehicles as well as heavy trucks. Traffic laws often apply different rules according to the vehicle's maximum authorised mass.
Why should other road users take extra care around trucks?
Trucks may have larger blind spots, longer stopping distances and wider turning paths than smaller vehicles, so other road users should avoid remaining unnecessarily close beside or in front of them.
182. Bus
A bus is a motor vehicle designed to transport multiple passengers, usually along roads as part of public transport, school transport, private transport or another passenger service. Buses generally have more passenger capacity than cars and may be designed to carry seated passengers, standing passengers or both.
Special rules may apply to buses concerning the driving licence, passenger capacity, speed limits, seat belts, bus lanes, stops and passenger boarding. The legal classification of buses and coaches and the rules applying to them vary between countries, so drivers and passengers must follow the local traffic regulations.
Wikimedia.org • Günthoa Schreyner • CC BY-SA
What is a bus?
A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.
What is the difference between a bus and a coach?
A bus is commonly designed for frequent passenger boarding and may allow standing passengers, while a coach is generally designed for longer journeys with passengers seated. Exact legal definitions vary between countries.
Do you need a special driving licence to drive a bus?
Yes. Driving a vehicle designed to carry more than a specified number of passengers normally requires a dedicated bus or passenger-vehicle driving licence.
Can passengers stand on a bus?
Only when the vehicle is designed and approved to carry standing passengers. Coaches and other vehicles designed exclusively for seated passengers must not be used beyond their approved passenger configuration.
Must bus passengers wear seat belts?
Where seat belts are provided and local law requires their use, passengers must wear them correctly. Urban buses designed for standing passengers may have seating positions or operating conditions that differ from coaches.
Can buses use bus lanes?
Yes, where permitted. Bus lanes are commonly reserved for public transport buses, although local signs may also allow taxis, bicycles or other specified vehicles to use them.
Do buses always have priority when leaving a bus stop?
No. Some countries require other drivers to give way to buses leaving designated stops, particularly in urban areas, while others apply the normal merging rules.
Should you take extra care near a stopped bus?
Yes. Passengers may be boarding, leaving or crossing the road near the bus. Reduce speed where necessary and watch carefully for pedestrians emerging from behind or in front of the vehicle.
Do buses have special speed limits?
They can. Some countries impose lower maximum speeds on buses than on passenger cars, particularly on high-speed roads. Different limits may apply to buses and coaches.
Can a bus use a motorway?
Yes, normally. Buses that satisfy the applicable construction and access requirements may use motorways, but they must obey any vehicle-specific speed limits, lane restrictions and other local rules.
183. Police
Police are public authorities responsible for enforcing laws, maintaining public safety and managing situations that may affect road traffic. In traffic, police officers may control vehicles, enforce traffic rules, investigate collisions, direct traffic and respond to emergencies.
Road users must follow lawful instructions given by police officers or other authorised traffic-control personnel. Police directions may temporarily override traffic lights, road signs or normal traffic arrangements, depending on local law.
Wikimedia.org • Soenke Rahn • CC BY-SA
What is the role of police in road traffic?
Police help enforce traffic laws, manage traffic, investigate collisions and respond to dangerous situations. They may also carry out roadside checks and direct road users.
Must you obey a police officer directing traffic?
Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.
What should you do if police signal you to stop?
Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.
Can police direct you through a red traffic light?
Yes, where authorised by local law. A police officer controlling traffic may instruct road users to proceed even when a traffic light or sign would normally require them to stop.
Can police check your driving documents?
Yes. Police may require drivers to provide documents such as a driving licence, vehicle registration, identification or proof of insurance according to local law.
Can police carry out alcohol or drug checks?
Yes. Traffic police may conduct legally authorised alcohol and drug checks using procedures such as breath, saliva or other approved tests.
Can police temporarily close a road?
Yes. Roads or lanes may be temporarily closed or traffic diverted because of collisions, emergencies, investigations, public events or other safety concerns.
What should you do near police controlling an accident scene?
Reduce speed, remain alert and follow all directions. Do not enter a closed area or interfere with emergency personnel, and leave sufficient space for emergency vehicles.
What should you do when a police vehicle approaches with emergency signals?
Follow the local rules for priority vehicles. Drivers generally have to make sufficient space, give way and stop where necessary so that the emergency vehicle can pass safely.
Can police order a parked vehicle to be moved?
Yes, where local law permits it. Police or another authorised authority may require a vehicle to be moved when it obstructs traffic, creates danger or must be removed for operational reasons.
184. Ambulance
An ambulance is a vehicle equipped and used to provide emergency medical assistance or transport patients to or between healthcare facilities. Ambulances may carry medical equipment and trained personnel who can provide treatment during transport.
During an emergency response, an ambulance may use warning lights and a siren and may receive special priority or exemptions from certain traffic rules. Other road users must follow the local rules for emergency vehicles, make sufficient space and avoid obstructing their passage.
Wikimedia.org • ITW Münster • CC BY-SA
What is an ambulance?
An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.
When does an ambulance have priority?
This depends on the local traffic rules and warning signals being used. Ambulances responding to emergencies commonly use flashing lights and a siren to indicate that other road users must make way.
What should you do when an ambulance approaches?
Remain calm and make sufficient space for it to pass. Slow down or stop where necessary, but avoid sudden or dangerous manoeuvres.
Should you stop immediately when you hear an ambulance siren?
Not necessarily in your exact position. Move or stop in a way that creates a safe passage without blocking an intersection, pedestrian crossing or another part of the road needed by the ambulance.
Can an ambulance pass a red traffic light?
Emergency vehicles may be allowed to pass a red light during an urgent response under special legal conditions. The precise rules differ between countries, and the ambulance driver must still take appropriate precautions.
Can an ambulance exceed the speed limit?
Many countries permit emergency vehicles to depart from certain normal speed rules during an urgent mission, subject to safety requirements and national legislation.
Can an ambulance drive through a traffic queue?
Yes, when responding to an emergency and legally permitted to do so. Other road users should create space and keep emergency corridors or access routes clear where required.
Can you follow an ambulance through traffic?
You should not use the passage created for an ambulance as a way to bypass congestion. Maintain a safe distance and continue to obey the normal traffic rules.
Do ambulances always use their sirens?
No. The use of warning lights and sirens depends on the urgency of the mission and local regulations. An ambulance transporting a patient does not necessarily need to use emergency signals throughout the journey.
What should you do near a stationary ambulance?
Reduce speed and remain alert. Medical personnel, patients or other emergency workers may be entering the road, and the ambulance may need to move unexpectedly.
185. Taxi
A taxi is a vehicle used to transport passengers for payment, usually providing individual or small-group journeys between locations chosen by the passenger. Taxi services may operate from designated taxi stands, accept street hails or be booked by telephone or digital platform.
Taxis are commonly identified by special markings, roof signs, licence plates or local taxi permits. The licensing, fare and operating rules vary between countries and cities.
Wikimedia.org • Petar Milošević • CC BY-SA
What is a taxi?
A taxi is a vehicle used to transport passengers for payment, normally providing journeys requested by individual customers.
Where can passengers find a taxi?
Depending on the local system, taxis may be available at taxi stands, airports, railway stations, on the street or through telephone and app-based booking services.
Are taxis regulated?
Yes. Taxi services are generally subject to licensing and operating requirements, although the exact rules concerning vehicles, drivers, fares and permitted operating areas vary between jurisdictions.
186. Police signals
Police signals are hand gestures, body positions, lights or other signals used by police officers or other authorised persons to control traffic. They may require road users to stop, proceed, change direction or follow another temporary traffic arrangement.
Road users should observe and obey police signals even when they differ from the normal traffic signs or signals. The exact gestures and their meanings vary between countries.
Wikimedia.org • Alvesgaspar • CC BY-SA
What are police traffic signals?
Police traffic signals are gestures, positions or other signals used by authorised officers to regulate or direct traffic.
Do police signals override traffic lights?
In many countries, yes. Directions given by an authorised traffic officer normally take precedence over traffic lights, signs and ordinary traffic rules.
What should you do if a police officer gives a signal you do not expect?
Slow down, pay close attention and follow the officer's instruction. Do not continue simply because a traffic light or road sign would normally allow you to proceed.
187. Rescue lane
A rescue lane, also called an emergency corridor, is a clear space created between lanes of congested traffic so emergency and authorised assistance vehicles can reach an incident quickly. Drivers normally form the lane as soon as traffic becomes heavily congested rather than waiting until an emergency vehicle approaches. The exact position of the rescue lane and which vehicles may use it vary between countries, so drivers should know the local rules before travelling.
Wikimedia.org • TypeZero • CC BY-SA
What is a rescue lane?
A rescue lane is a clear corridor formed between lanes of congested traffic so emergency and authorised assistance vehicles can pass.
When should you create a rescue lane?
Where required, drivers should normally form the rescue lane as soon as a traffic jam develops, rather than waiting until an emergency vehicle approaches.
Where is a rescue lane formed?
The position depends on local rules. A common system creates the corridor between the leftmost lane and the lane immediately to its right.
Why should the rescue lane be formed before an emergency vehicle arrives?
Creating the corridor early gives emergency vehicles a clear route through stationary or slow-moving traffic and avoids drivers having to move suddenly when space is already limited.
Can ordinary drivers use a rescue lane?
Normally, no. Rescue lanes are generally reserved for emergency vehicles and other specifically authorised vehicles. The exact rules differ between countries.
Is a rescue lane the same as the hard shoulder?
No. A rescue lane is created between traffic lanes, while the hard shoulder is a separate part of the road beside the carriageway.
188. Tailgating
Tailgating means driving too closely behind another vehicle without leaving enough distance to react and stop safely if the vehicle ahead slows down or stops suddenly. The safe following distance depends on factors such as speed, road conditions, weather and visibility.
Drivers should leave sufficient space between their vehicle and the vehicle ahead and increase that distance in rain, snow, fog or other conditions that increase stopping distance.
Wikimedia.org • Marc Mongenet • CC BY-SA
What is tailgating?
Tailgating means following another vehicle too closely to maintain a safe stopping distance.
Why is tailgating dangerous?
Following too closely gives the driver less time and distance to react if the vehicle ahead brakes, slows down or encounters an unexpected hazard.
When should you increase your following distance?
You should increase the distance in conditions such as rain, snow, ice, fog, darkness or poor road surfaces and whenever visibility or tyre grip is reduced.
189. Bicycle parking station
A bicycle parking station is a designated place or facility where bicycles can be parked and secured. It may consist of simple bicycle racks or a larger covered, enclosed or access-controlled parking facility with many bicycle spaces.
Bicycle parking stations are commonly provided near railway stations, public-transport stops, workplaces, schools, shopping areas and city centres. Users should park their bicycles in the designated spaces, secure them properly and avoid obstructing pedestrian routes, cycle facilities, entrances or other road users.
Wikimedia.org • Donald Trung Quoc Don • CC BY-SA
What is a bicycle parking station?
A bicycle parking station is a designated facility where bicycles can be parked and secured.
What facilities can bicycle parking stations provide?
They may provide bicycle racks, covered parking, lockers, access control, surveillance or spaces for larger bicycles. Facilities vary between locations.
Where are bicycle parking stations commonly found?
They are commonly provided near railway stations, public-transport hubs, schools, workplaces, shopping areas and busy city centres.
Should you lock your bicycle in a bicycle parking station?
Yes. Even in a designated or secure facility, the bicycle should normally be locked appropriately to reduce the risk of theft.
Can a bicycle parking station be free?
Yes. Bicycle parking may be free or subject to payment, particularly where secure, enclosed or access-controlled facilities are provided.
Can electric bicycles use bicycle parking stations?
Yes, normally. Some facilities may also provide charging points, although the bicycle and battery must comply with the operator's safety rules.
Can cargo bikes use ordinary bicycle parking?
Only where there is sufficient space and the facility permits them. Larger bicycle parking stations may provide special spaces for cargo bikes, longtails or other oversized cycles.
Can speed pedelecs use bicycle parking stations?
This depends on the signs and facility rules. Some parking facilities accommodate both ordinary bicycles and speed pedelecs, while others reserve separate spaces.
Can you leave a bicycle outside a designated parking station?
This depends on local law. Where parking elsewhere is permitted, the bicycle should be positioned so that it does not obstruct or endanger pedestrians, cyclists or other road users.
Can bicycles block pedestrian routes when parked?
No. Bicycle parking should leave sufficient space for pedestrians, including people using wheelchairs, mobility aids or tactile guidance routes.
Can an abandoned bicycle be removed from a parking station?
Yes, depending on local rules and facility conditions. Operators or authorities may remove bicycles that are abandoned, incorrectly parked or left beyond the permitted period.
What is secure bicycle parking?
Secure bicycle parking provides additional protection against theft through measures such as controlled access, enclosed storage, surveillance or individual bicycle lockers.
190. Gravel road
A gravel road is an unpaved road surfaced with gravel, crushed stone or similar loose aggregate instead of asphalt or concrete. Gravel roads are commonly found in rural areas, forests, construction zones and locations where a paved surface is unnecessary or impractical.
Drivers on gravel roads should reduce speed when necessary, increase following distance and avoid sudden braking or steering. Loose stones, dust, potholes and reduced tyre grip can make vehicle control more difficult.
Wikimedia.org • Idawriter • CC BY-SA
What is a gravel road?
A gravel road is an unpaved road covered with gravel, crushed stone or another loose aggregate surface.
Why can gravel roads be more difficult to drive on?
Loose material can reduce tyre grip, increase stopping distance and cause stones or dust to be thrown into the air. Potholes and uneven surfaces may also be present.
How should you drive on a gravel road?
Use a suitable speed, maintain extra distance from other vehicles and accelerate, brake and steer smoothly to reduce the risk of losing traction.
191. Tram lights
Tram lights are special traffic signals used to control the movement of trams and, in some countries, other public-transport vehicles. They are often designed differently from ordinary red, amber and green traffic lights so that public-transport drivers can clearly distinguish the signals intended for them.
The signals may indicate stop, prepare to stop, proceed or proceed only in a specified direction. Their shapes, colours and meanings vary between countries, so road users must follow the local traffic-signal system and regulations.
Wikimedia.org • Robot8A • CC BY-SA
What are tram lights?
Tram lights are special traffic signals used to control trams and sometimes other authorised public-transport vehicles.
Why are tram lights different from normal traffic lights?
Using different symbols, shapes or colours makes it easier for tram and public-transport drivers to distinguish their signals from the red, amber and green lights controlling ordinary road traffic.
Do tram lights have the same meaning in every country?
No. The appearance and meaning of public-transport signals vary between countries and sometimes between transport systems.
Can tram lights indicate different directions?
Yes. Special signals may permit a tram to continue straight ahead, turn left or turn right while other movements remain prohibited.
Do ordinary motorists have to follow tram lights?
Normally no when the signals are specifically intended for trams or public-transport vehicles. Ordinary drivers must follow the traffic lights and signs that apply to them.
Can tram lights operate differently from ordinary traffic lights?
Yes. Public-transport signals may allow a tram to proceed while ordinary traffic remains stopped, helping the tram cross an intersection or receive priority through traffic.
Can cyclists ever have to follow tram lights?
In some road layouts, cyclists or other authorised users may share infrastructure controlled by public-transport signals. Whether those signals apply to them depends on local traffic law and signage.
Does a signal allowing a tram to proceed mean other traffic may also proceed?
No. A signal intended specifically for a tram or public-transport vehicle does not give permission to other road users unless their own signal or traffic rule also permits them to proceed.
What should drivers do near tram signals?
Follow the signals intended for your own traffic stream, remain alert for approaching trams and avoid stopping where you could obstruct the tracks.
Do tram lights replace normal priority rules for everyone?
No. They primarily regulate the vehicles to which they apply. Other road users must continue to obey their own traffic lights, signs and applicable priority rules.
192. European emission standard
A European emission standard, commonly called a Euro standard, is a European vehicle classification based on limits for pollutants emitted by vehicles and their engines. Successive standards, such as Euro 4, Euro 5 and Euro 6, introduced progressively stricter requirements for pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons.
A vehicle's Euro standard is determined as part of its type approval and depends on factors including the vehicle category, fuel type and applicable emissions legislation when it was approved. Euro standards may also be used by authorities to determine access to low-emission zones, but local access rules vary between countries and cities.
Wikimedia.org • Rfeba • CC0
What is a European emission standard?
A European emission standard, or Euro standard, classifies vehicles according to the emissions requirements they had to satisfy when approved for use in the European market.
What do Euro 4, Euro 5 and Euro 6 mean?
They are successive generations of European emission requirements. In general, a higher Euro number represents a newer and stricter emissions standard, although the exact limits differ according to vehicle and fuel type.
Which pollutants do Euro standards regulate?
Depending on the vehicle and standard, limits apply to pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons. Newer standards also regulate additional environmental aspects.
Is the Euro standard the same as a vehicle's CO2 emissions?
No. Euro standards primarily regulate harmful air pollutants from vehicles. Carbon-dioxide emissions and fuel or energy consumption are subject to separate measurements and regulatory requirements.
How can you find a vehicle's Euro standard?
The Euro standard may appear on the vehicle registration certificate, certificate of conformity or other official vehicle documentation. Its location and format vary between countries.
Does the year of a vehicle determine its Euro standard?
The date of first registration can provide an indication, but it does not always determine the standard with certainty. The official vehicle documents or type-approval information provide the more reliable classification.
Can petrol and diesel vehicles with the same Euro number have different emission limits?
Yes. The applicable emission limits and testing requirements can differ according to the vehicle category, engine and fuel type even when vehicles belong to the same general Euro generation.
Can the Euro standard affect access to a low-emission zone?
Yes. Many low-emission zones use the vehicle's Euro standard together with factors such as fuel type and vehicle category to determine whether it may enter.
Does installing a particulate filter automatically change the Euro standard?
Not normally. The official Euro standard is linked to the vehicle's approved emissions classification. Retrofitting emission-control equipment does not necessarily result in a different official Euro classification.
What is Euro 7?
Euro 7 is the latest European emissions framework for road vehicles. It builds on earlier Euro standards and also introduces requirements covering areas such as non-exhaust particle emissions and battery durability.
193. Public road
A public road is a road, street, path or other traffic area that is open for use by the public. It can contain different parts intended for motor vehicles, cyclists, pedestrians and other road users, such as carriageways, cycle paths, pavements, verges and parking areas.
Different parts of a public road may be reserved for particular categories of road users and can be subject to different traffic rules. Everyone using the public road must follow the applicable traffic signs, signals, road markings and local traffic regulations.
Wikimedia.org • sfu • CC BY-SA
What is a public road?
A public road is a road, street, path or other traffic area that is open for use by the public.
Is the public road the same as the carriageway?
No. The carriageway is normally only the part of the road intended primarily for vehicle traffic. The public road can also include cycle paths, pavements, verges and other areas.
Can a public road include a pavement?
Yes. Pavements or sidewalks intended for pedestrians can form part of the public road even though motor vehicles normally may not use them.
Can a cycle path be part of the public road?
Yes. A cycle path can form a separate part of the public road reserved for bicycles and other permitted road users.
Can a public road include a verge?
Yes. Verges beside the carriageway can form part of the public road and may be subject to specific rules concerning walking, cycling, stopping or parking.
Does a public road have to be owned by the government?
Not necessarily. In some legal systems, whether a road is considered public depends mainly on whether it is open to public traffic rather than simply on who owns the land.
Do traffic rules apply on every public road?
Yes, generally. Road users must comply with the traffic regulations applying to the road and to the particular part of it they are using.
Can parts of a public road be reserved for certain road users?
Yes. Cycle paths, pavements, bus lanes, pedestrian areas and other sections may be reserved for specified categories of road users.
Can access to a public road be restricted?
Yes. Traffic signs or regulations may prohibit or restrict particular vehicles or road users even though the road remains part of the public-road network.
Can a public road be temporarily closed?
Yes. Roads can be temporarily closed or restricted because of roadworks, emergencies, events or other traffic-management measures.
Does a path count as a public road?
It can. A path that is legally open to public traffic may form part of the public-road network even when only pedestrians, cyclists or other limited categories of road users can use it.
What should you do when entering a public road from private property?
Follow the local rules for entering traffic from a driveway, property or other private area. Drivers commonly have to give way to road users already using the public road.
194. Roadway
A roadway, also called a carriageway, is the part of a road primarily intended for the movement of vehicles. A roadway may carry traffic in one or both directions and may be divided into one or more traffic lanes.
The roadway is only one part of the wider road environment. Cycle paths, pavements, verges, parking areas and other roadside facilities may form separate parts of the road and can be subject to different traffic rules.
Wikimedia.org • welshbabe • CC BY-SA
What is a roadway?
A roadway, or carriageway, is the part of a road primarily intended for the movement of vehicles.
Is the roadway the same as the entire road?
No. The complete road can also contain pavements, cycle paths, verges, parking areas, central reservations and other sections that do not form part of the roadway.
Is a traffic lane the same as a roadway?
No. A traffic lane is a portion of the roadway intended for a line of moving vehicles. A roadway may contain one or several lanes.
Can a roadway carry traffic in both directions?
Yes. A roadway may carry two-way traffic or may be restricted to traffic travelling in only one direction.
Is a cycle path part of the roadway?
Normally no when it is legally designated as a separate cycle facility. It may form part of the wider road while remaining separate from the roadway.
Is a pavement part of the roadway?
No. A pavement or sidewalk is normally a separate part of the road intended primarily for pedestrians.
Can a parking area be separate from the roadway?
Yes. A designated parking strip or parking area may form a separate part of the road alongside the roadway.
Where should drivers normally travel?
Drivers normally use the roadway and the traffic lanes intended for their direction of travel, except where another part of the road is specifically provided or permitted for their vehicle category.
Can cyclists use the roadway?
Yes. Cyclists may or must use the roadway when permitted by local rules, particularly where no applicable cycle facility is available or compulsory.
Can pedestrians use the roadway?
Pedestrians may sometimes use the roadway when no suitable pedestrian facility is available, subject to the local rules governing their position and direction of travel.
Can road markings divide a roadway into lanes?
Yes. Continuous or broken longitudinal road markings commonly divide a roadway into individual traffic lanes and regulate how drivers may move between them.
Can different parts of the same road have different rules?
Yes. The roadway, cycle paths, pavements, parking areas and other sections may each have different permitted users and traffic rules.
195. Street
A street is a road in a built-up or developed area that provides access to homes, businesses, schools, shops and other properties or activities. Streets are commonly shared by several types of road users, including motorists, cyclists and pedestrians.
A street may contain a roadway, pavements, cycle facilities, parking spaces, public-transport stops and other infrastructure. Speed limits, priority rules, parking restrictions and permitted road users depend on the local traffic signs, road design and regulations.

What is a street?
A street is a road in a built-up or developed area that commonly provides access to buildings, properties and activities along it.
Is a street the same as a road?
Not exactly. Road is a broader term that can include motorways, rural roads and other routes. A street is normally associated with a built-up area and access to properties or activities.
Is a street the same as the roadway?
No. The roadway or carriageway is the part primarily intended for vehicle traffic. A street can also contain pavements, cycle facilities, parking areas and other infrastructure.
Can pedestrians use a street?
Yes. Pedestrians normally use the pavement, sidewalk or other pedestrian facilities provided along the street and cross the roadway according to the applicable crossing rules.
Can cyclists use a street?
Yes. Cyclists may use cycle paths, cycle lanes or the roadway according to the local traffic rules and infrastructure.
Can a street have one-way traffic?
Yes. A street may be restricted to vehicles travelling in one direction, while signs may sometimes allow particular road users such as cyclists to travel in both directions.
Can a street be closed to motor vehicles?
Yes. Streets may form pedestrian zones, school streets, play streets or other restricted areas where motor-vehicle access is prohibited or limited.
Is there one speed limit for all streets?
No. The applicable speed depends on the country, location, type of street and traffic signs. Special lower limits commonly apply in residential, school or pedestrian-oriented areas.
Can cars park on a street?
Yes, where parking is permitted. Drivers must respect parking signs, road markings and general restrictions concerning crossings, intersections, driveways and other protected locations.
Can public transport use a street?
Yes. Streets may carry buses, trams or other public transport and can include dedicated lanes, tracks and passenger stops.
Can a street include a cycle path?
Yes. A cycle path may run along a street while remaining a separate part of the road from the ordinary roadway.
What should drivers expect on a street?
Drivers should expect frequent interaction with pedestrians, cyclists, parked vehicles, intersections, driveways and public transport and should adapt their speed and observation accordingly.
196. Pothole
A pothole is a hole or depression in the road surface caused by wear, weather, water, repeated traffic loads or deterioration of the pavement. Potholes can vary greatly in size and depth and may develop gradually or become worse after freezing, heavy rain or repeated vehicle traffic.
Potholes can affect steering, braking and vehicle stability and may damage tyres, wheels or suspension components. Drivers and riders should observe the road ahead, adapt their speed and avoid sudden or dangerous manoeuvres when encountering damaged road surfaces.

What is a pothole?
A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.
How do potholes form?
Potholes can develop through a combination of water, temperature changes, traffic loads and deterioration of the road material. Cracks can gradually expand until pieces of the surface break away.
Why are potholes dangerous?
A pothole can cause a vehicle to change direction suddenly, lose stability or suffer tyre, wheel or suspension damage. Deep potholes can present a particularly serious hazard at higher speeds.
What should you do when you see a pothole?
Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.
Should you brake while driving through a pothole?
If possible, reduce your speed before reaching the pothole. Sudden heavy braking or steering while passing over a damaged surface can make the vehicle less stable.
Are potholes particularly dangerous for motorcycles?
Yes. A pothole can disturb the steering or balance of a motorcycle and may cause the rider to lose control.
Are potholes dangerous for cyclists?
Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.
Can a pothole damage a car?
Yes. Severe impacts can damage tyres, wheel rims, suspension components, steering parts or wheel alignment.
Should you swerve suddenly to avoid a pothole?
No. A sudden evasive movement may create a greater danger by bringing the vehicle into conflict with cyclists, pedestrians, oncoming traffic or vehicles in another lane.
Can a warning sign indicate potholes ahead?
Yes. Depending on the country's traffic-sign system, an uneven-road or general-danger warning sign may be used where poor road conditions create a significant hazard.
197. Median strip
A median strip, also called a central reservation or median, is an area running longitudinally between separate roadways, usually to divide traffic travelling in opposite directions. It may consist of grass, paving, barriers, vegetation or another physical separation.
A median strip helps separate opposing traffic flows and can reduce the risk of vehicles crossing directly into oncoming traffic. Openings may be provided at selected locations for turning traffic, intersections, emergency access or other authorised movements.

What is a median strip?
A median strip is a longitudinal area that separates two roadways, usually carrying traffic in opposite directions.
Is a median strip the same as a road marking?
Not necessarily. A median is normally a physically distinguishable area or structure, while painted centre lines simply separate traffic using road markings.
What can a median strip be made of?
A median may consist of grass, paving, kerbs, safety barriers, vegetation or another physical separation between roadways.
Why are median strips used?
They help separate opposing traffic flows, reduce conflicts between vehicles travelling in opposite directions and provide space for barriers, signs, lighting or other road infrastructure.
Can you drive across a median strip?
Only where a legal crossing or opening is provided and the applicable traffic rules permit the movement. Drivers should never cross a physical median simply to change direction or take a shortcut.
Can a median strip have openings?
Yes. Openings may be provided for intersections, turning movements, emergency services, maintenance or other authorised traffic.
Can you park on a median strip?
This depends on local law, but parking on a median is commonly prohibited or restricted because it may create danger or obstruct visibility and traffic.
Can pedestrians stand on a median strip?
Some medians contain a pedestrian refuge specifically designed to allow people to cross a road in stages. Other medians may not be intended for pedestrian use.
Is a central safety barrier part of the median?
It can be. A median may contain a safety barrier designed to reduce the risk of vehicles crossing into opposing traffic.
Can a divided road have more than one roadway?
Yes. A road with a median commonly has two separate roadways, one for each direction of traffic.
Does a median strip determine the direction of traffic?
The road layout normally separates the traffic directions, but drivers must still follow the traffic signs, lane markings and directional rules applying to each roadway.
Is a median strip the same as an emergency lane?
No. An emergency lane or shoulder runs alongside a roadway, while a median strip separates roadways from each other.
198. Public property
Public property is land, buildings, infrastructure or other property owned or controlled by a government or other public authority. Examples can include roads, parks, public squares, government buildings, railway infrastructure and other facilities used for public services.
Public property is not necessarily freely accessible to everyone. Some public property is open to general public use, while other areas may have restricted access or be reserved for particular services. Traffic rules depend on whether the area forms part of a public road or another place to which the relevant traffic laws apply.

What is public property?
Public property is property owned or controlled by a government, municipality or another public authority.
What are examples of public property?
Examples can include roads, parks, public squares, government buildings, transport infrastructure and other public facilities.
Is all public property open to everyone?
No. Some public property is freely accessible, while access to government offices, maintenance facilities, railway infrastructure or other areas may be limited or prohibited.
Is public property the same as a public road?
No. Public property concerns ownership or control, while a public road concerns an area that is legally or actually open to public traffic. A public road can therefore be only one type of public property.
Can privately owned land be open to the public?
Yes. A privately owned car park, road or other area may be accessible to the public even though the government does not own it.
Can publicly owned land be closed to the public?
Yes. Public authorities can own areas that are restricted to authorised personnel, maintenance services or other specified users.
Do traffic rules automatically apply to all public property?
No. Whether ordinary road-traffic rules apply depends on the legal status and use of the area rather than simply on who owns it.
Can public property contain roads and parking areas?
Yes. Public property can include streets, car parks, access roads and other traffic areas, each of which may have its own traffic and access rules.
Can access to public property be restricted by signs?
Yes. Signs, barriers, opening hours, permits or other regulations may restrict access to particular public areas.
Can vehicles be prohibited from public property?
Yes. A publicly accessible park, square or pedestrian area may prohibit motor vehicles or permit only specific categories such as emergency, maintenance or delivery vehicles.
Is public property the same as public space?
Not necessarily. Public space generally describes an area available for public use, while public property primarily describes ownership or control. A publicly used space can sometimes be privately owned.
Why is the distinction important for traffic rules?
Traffic regulations frequently depend on whether an area is a public road, publicly accessible place or restricted private area, rather than solely on ownership.
199. Private property
Private property is land, buildings or other property owned or controlled by a private person, company or organisation rather than by a public authority. Examples can include private homes, driveways, company grounds, private car parks and access roads.
Private property may be completely closed to the public or may allow access to customers, visitors or other authorised users. The traffic rules that apply depend not only on ownership but also on whether the area is open to public traffic and how it is legally classified.

What is private property?
Private property is land, buildings or other property owned or controlled by a private person, company or organisation.
What are examples of private property?
Examples include homes, driveways, private roads, company grounds, shopping-centre car parks and privately owned parking facilities.
Is private property always closed to the public?
No. Some private property is restricted to its owner or authorised users, while other privately owned areas are open to customers, visitors or the general public.
Is private property the same as a private road?
No. A private road is only one type of private property. Private property can also include buildings, car parks, yards and other land.
Can a privately owned road be open to public traffic?
Yes. Ownership and public accessibility are separate issues. A privately owned road can be made available to public traffic and may then be subject to traffic rules that normally apply to public roads.
Do road traffic rules apply on every private driveway?
Not necessarily. The applicable rules depend on the legal status and accessibility of the area. A driveway used only by its owner is different from a privately owned road that is open to general traffic.
Can the owner restrict access to private property?
Yes, subject to applicable law. Access may be limited using gates, barriers, permits, signs or other conditions established by the owner or operator.
Can a private car park be open to the public?
Yes. A privately owned supermarket, shopping-centre or commercial car park can be accessible to customers or the general public even though the land remains privately owned.
Can vehicles be removed from private property?
This depends on local law and the circumstances. Owners or authorised operators may have procedures for dealing with vehicles that are unlawfully parked or obstruct access.
What should you do when leaving private property and entering a road?
Enter carefully and follow the applicable rules for joining traffic from a driveway or adjoining property. In many countries, the driver entering the road must give way to road users already using it.
Can traffic signs be placed on private property?
Yes. Owners may use signs to indicate access, parking or safety conditions, although their legal status and enforceability can differ from official road signs installed on public roads.
Why is the distinction between private property and public road important?
Because traffic laws often depend on the legal status and accessibility of the place rather than simply on who owns the land.
200. Private road
A private road is a road located on private property whose use is controlled or restricted by its owner or operator. It may serve homes, businesses, industrial sites, farms, car parks or other privately managed property.
A private road may be completely closed to the public or accessible only to residents, customers, employees, visitors or other authorised users. Whether ordinary road-traffic rules apply depends on the legal status and public accessibility of the road, not simply on who owns the land.

What is a private road?
A private road is a road whose access and use are controlled by a private owner or organisation rather than being freely available as part of the ordinary public-road network.
Who may use a private road?
This depends on the owner's access rules. Use may be limited to residents, visitors, customers, employees, delivery vehicles or other authorised persons.
Can a private road be open to the public?
Yes. A privately owned road may be made available to general public traffic. In some legal systems, this can affect which traffic rules apply to it.
Is a private road the same as private property?
No. A private road is one particular type of private property. Private property can also include buildings, gardens, yards, car parks and other land.
Can the owner close a private road?
Generally yes, subject to applicable legal rights and restrictions. Access can be controlled by gates, barriers, signs or permits.
Do traffic signs on a private road have the same legal status as official road signs?
Not necessarily. Their legal effect depends on the country, road status and authority under which they were installed.
Do normal speed limits apply on a private road?
This depends on whether the road falls within the scope of the country's road-traffic legislation. The owner may also impose additional private speed restrictions.
Can you park on a private road?
Only when the owner's rules and applicable law permit it. Parking may be reserved, restricted or prohibited.
Can unauthorised vehicles be removed from a private road?
Depending on local law, the owner or operator may be able to arrange removal of vehicles that are unauthorised, abandoned or obstructing access.
What should you do when leaving a private road?
Approach the public road carefully and follow the applicable rules for joining traffic from private property or an access road. Drivers commonly have to give way to road users already using the public road.
Can emergency vehicles enter a private road?
Yes, where their duties and local law permit it. Access may be necessary for fire, medical, police or rescue operations.
Why is the legal status of a private road important?
It determines whether ordinary road-traffic rules, insurance requirements, traffic signs and enforcement powers apply in the same way as they do on a public road.
