76. 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.

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.
77. 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.

78. 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 • MOs810 • CC BY-SA
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.

79. 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.

80. 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 • Silar • CC BY-SA
What is the role of police in road traffic?
Police help enforce traffic law, investigate collisions and respond to risks on the road. For example, Greater Manchester Police describe targeted road enforcement, a round-the-clock roads-policing response and specialist serious-collision investigation. Exact responsibilities and powers vary by jurisdiction.
🔗 gmp.police.uk • Greater Manchester Police, Roads Policing Strategy2024–2026
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.
81. 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.

What is an ambulance?
An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.
🔗 gov.uk • Great Britain Highway Code, Rule 219, emergency vehicles; national guidance example
What should you do when an ambulance approaches?
Make space safely for an ambulance on an emergency response, following the local rules and any lawful directions. Slow down or stop where necessary without sudden or dangerous movements. Do not assume that its emergency status allows you to pass a red light or disregard another traffic control.
🔗 gov.uk • Great Britain Highway Code, Rule 219, emergency vehicles; national guidance example
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.
🔗 gov.uk • Great Britain Highway Code, Rule 219, emergency vehicles; national guidance example
82. 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 • MOs810 • CC BY-SA
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.
83. 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.
🔗 consilium.europa.eu • Council of the EU, Euro 7 adoption explanation, 12 April 2024
What do Euro 4, Euro 5 and Euro 6 mean?
Euro 4, Euro 5 and Euro 6 identify successive stages of European vehicle-pollutant requirements. The applicable limits depend on the vehicle, engine and pollutant, so a higher number does not mean that every individual numerical limit changed. Later stages can also alter testing and durability requirements.
🔗 consilium.europa.eu • Council of the EU, Euro 7 adoption explanation, 12 April 2024
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.

84. 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.
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.
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.
85. 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.
Wikimedia.org • State Farm • CC BY
What is a pothole?
A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.
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.
🔗 gov.uk • Great Britain Highway Code, Rules 226–237; national guidance example
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.
🔗 gov.uk • Great Britain Highway Code, Rules 226–237; national guidance example
86. 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.
Wikimedia.org • Panek • CC BY-SA
What is private property?
Private property is property belonging to a private person or group, rather than being available for everyone’s use. In a road context, check the actual access rules before entering private land.
🔗 dictionary.cambridge.org • Cambridge Dictionary, ordinary private-property definition
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.

87. Path
A path is a relatively narrow route intended for pedestrians and, where permitted, other road users or small vehicles. Paths may run through urban areas, countryside, parks, forests or between other roads and can be surfaced or unsurfaced.
A path is not necessarily the same as a footpath or cycle path. The road users permitted to use it depend on its legal status, width, traffic signs and local regulations.
Wikimedia.org • Tangopaso • CC0
Is a path the same as a footpath?
Not necessarily. A footpath is specifically intended for pedestrians, while a path may also permit cyclists or other users according to local rules.
Can cyclists use a path?
This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.
Can motor vehicles use a path?
This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.
Who has priority when a path joins a larger road?
The applicable local priority rules determine who must give way. Special rules often apply when a minor path joins an ordinary road.
88. Particulates
Particulates, or particulate matter (PM), are tiny solid particles or liquid droplets suspended in the air. In road traffic, particulate emissions can come from vehicle exhaust, brake wear, tyre wear and road-surface wear, as well as dust that is disturbed by passing traffic.
Particulate matter is commonly classified by particle size. PM10 refers to particles with a diameter of up to approximately 10 micrometres, while PM2.5 refers to finer particles of up to approximately 2.5 micrometres. Vehicle emission standards, particulate filters and air-quality measures are used to reduce exposure to these pollutants.

89. Air pollution
Air pollution is the presence of gases, particles or other substances in the air at concentrations that can harm human health, the environment or ecosystems. Road traffic contributes to air pollution through exhaust emissions and through non-exhaust sources such as brake wear, tyre wear and road dust.
Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Some pollutants are emitted directly by vehicles, while others can form in the atmosphere through chemical reactions. Vehicle-emission standards, cleaner technologies and traffic-management measures are used to reduce these emissions.
Wikimedia.org • Emmanuelkwizera • CC BY-SA
What is air pollution?
Air pollution is the presence of harmful gases, particles or other contaminants in the air. Road transport can contribute through engine emissions, vehicle wear and dust; the sources and pollutants differ by vehicle and conditions.

90. Rush hour
Rush hour is a period when roads and public transport networks experience particularly high demand, commonly because large numbers of people are travelling to or from work, school or other regular destinations. It usually occurs during the morning and late afternoon or evening on working days.
Rush-hour traffic can result in congestion, slower speeds, longer journeys and frequent stopping. Drivers should maintain a safe following distance, remain patient, anticipate changing traffic conditions and follow any temporary or dynamic traffic-management measures.
Wikimedia.org • MDRX • CC BY-SA
What is rush hour?
Rush hour is a period when unusually large numbers of people travel at the same time, resulting in increased traffic and often congestion.

91. Road code
A road code is a collection of laws and traffic rules that regulate how people use public roads. It establishes rules for drivers, cyclists, pedestrians and other road users and covers subjects such as priority, speed, overtaking, parking, traffic lights, road signs and road markings.
Road codes differ between countries and sometimes between regions. Every road user is expected to know and follow the rules that apply where they are travelling, even when those rules differ from those in their home country.
Are road codes the same in every country?
No. Although many traffic rules and signs are similar internationally, each country establishes its own traffic legislation and may apply different rules, signs, speed limits and requirements.
92. Two-way traffic
Two-way traffic means that vehicles are permitted to travel in opposite directions on the same road or carriageway. The opposing traffic streams may be separated by road markings, a central reservation or, on narrower roads, no physical separation at all.
Drivers on a two-way road should keep to the side required by local traffic rules, remain aware of approaching vehicles and take particular care when overtaking, turning or passing through narrow sections.
Wikimedia.org • MOs810 • CC BY-SA
Why should you take extra care on a two-way road?
Vehicles may approach from the opposite direction, so drivers should maintain a safe position and take particular care when overtaking, turning or passing through narrow sections.

🔗 gov.uk • Great Britain Highway Code, Rules 135–138; national guidance example
93. Street gutter
A street gutter is a narrow channel along the edge of a road or street that collects and carries rainwater toward drains or other drainage systems. It is commonly located between the carriageway and the kerb and may be formed from concrete, paving stones or part of the road surface.
A street gutter is primarily a drainage feature rather than a traffic lane. Road users should take care near gutters because they may contain water, debris, drain openings or uneven surfaces.
Wikimedia.org • Airman 1st Class Alystria Maurer • CC0
Why should cyclists take care near street gutters?
Gutters may contain water, leaves, debris, drain covers or uneven surfaces, which can reduce grip or make cycling less stable.

What should you do when passing a construction vehicle?
Reduce speed where necessary and leave sufficient space. Be aware of blind spots, projecting equipment, wide turns and workers who may be present nearby.
97. Semi-trailer truck
A semi-trailer truck is a combination consisting of a road tractor and a semi-trailer used primarily for transporting goods. The semi-trailer is coupled to the tractor so that a significant part of its weight is supported by the tractor rather than entirely by its own wheels.
Semi-trailer trucks are commonly used for long-distance freight transport and may carry containers, refrigerated goods, liquids, bulk materials or other cargo. Special rules can apply concerning driving licences, maximum dimensions and masses, speed limits, lane use, overtaking, loading and driving and rest periods.

What is a semi-trailer truck?
A semi-trailer truck consists of a powered road tractor coupled to a semi-trailer primarily used to transport goods.
What is the difference between a semi-trailer and an ordinary trailer?
A semi-trailer is designed so that a substantial part of its own weight and load is supported by the towing vehicle. Other trailer designs support the load differently; some also impose a vertical load on the towing vehicle. Check the actual trailer and coupling ratings.
Do semi-trailer trucks have lower speed limits?
They often do. Many countries impose vehicle-specific maximum speeds on heavy goods vehicles, particularly on motorways and other high-speed roads.
98. Trolleybus
A trolleybus is an electrically powered bus that normally obtains its energy from overhead electrical wires through current collectors mounted on the vehicle. Unlike a tram, a trolleybus runs on ordinary road wheels and is steered by its driver rather than being guided by rails.
Trolleybuses are generally used for public passenger transport and may use bus lanes, stops and other public-transport infrastructure. Some modern trolleybuses also have batteries or auxiliary power systems that allow them to travel short distances without remaining connected to the overhead wires.

99. Speed pedelec
A speed pedelec is a high-speed electrically assisted bicycle whose motor can continue providing pedal assistance above the normal electric-bicycle assistance limit, typically up to approximately 45 km/h. It has pedals and is primarily designed to assist the rider while pedalling.
Because of its higher speed, a speed pedelec may legally be treated differently from an ordinary bicycle or electric bicycle. Special rules can apply concerning the minimum age, driving licence, helmet, registration, insurance, cycle-path use and permitted roads, depending on the country.
Wikimedia.org • Sänger • CC BY-SA
What is a speed pedelec?
In the Belgian example, a speed pedelec is an electrically assisted pedal vehicle in a faster legal category, with assistance up to 45 km/h. Other countries may classify faster electric bicycles differently; the name alone does not establish their legal status.
