51. Parking zone

A parking zone is an area where a particular parking rule applies throughout a group of streets or a defined district rather than only at a single parking place. The applicable rule may regulate whether parking is allowed, how long vehicles may remain parked, which vehicles may park or whether payment or a parking permit is required.

The beginning and end of a parking zone are normally indicated by zone signs. Drivers should check the information shown at the entrance because the parking conditions may continue to apply throughout the zone without being repeated on every street.

52. Axle weight limit

An axle weight limit is the maximum permitted weight or load carried by a single axle of a vehicle. It limits how much force an axle and its wheels may transmit to the road, independently of the vehicle's total weight.

Axle weight limits help protect bridges and road surfaces from excessive loads and contribute to safe vehicle operation. A vehicle can comply with an overall weight limit while still exceeding an axle limit if its load is distributed incorrectly.

53. Licence plate

A licence plate, also called a registration plate or number plate, is a plate displaying a unique registration identifier assigned to a vehicle by the competent registration authority. It allows the vehicle to be identified for purposes such as registration, traffic enforcement, taxation, insurance and parking control.

The appearance, format, placement and number of plates required vary between countries and vehicle categories. Drivers must ensure that required licence plates are correctly fitted, clearly visible and legible and must follow the local rules when a plate is lost, stolen, damaged or replaced.

57. 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.

58. 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.

59. 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.

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.

🔗 wetten.overheid.nl • Vienna Convention on Road Traffic, Articles 5–6, authorised officials and directions; international framework subject to national law

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.

🔗 wegcode.be • Belgium, Road Code of 1 December 1975

Can speed pedelecs use bicycle parking stations?

Check the signs and the facility’s admission rules before using a space with a speed pedelec. Vehicle reservations can differ: for example, Belgian M19 reserves parking for speed pedelecs, while M20 covers bicycles and speed pedelecs together. A bicycle-parking label alone does not establish permission for every vehicle.

🔗 wegcode.be • Belgium, Road Code of 1 December 1975

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.

🔗 wegcode.be • Belgium, Road Code of 1 December 1975

63. 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.

64. 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.

🔗 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.

65. 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.

66. 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.

67. 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.

68. 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.

69. 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.

70. 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.

71. 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.

72. Cargo bike

A cargo bike is a bicycle designed to transport goods, children or other larger loads than can normally be carried on a conventional bicycle. Cargo bikes may use a box or platform in front of or behind the rider, an extended rear carrier or a multi-wheel design.

Cargo bikes can be powered entirely by the rider or equipped with electric pedal assistance. Their permitted dimensions, passenger capacity, use of cycle paths and electrical-assistance limits depend on the local traffic and vehicle regulations.

73. Forestry vehicle

A forestry vehicle is a vehicle designed, equipped or adapted for work connected with forestry and woodland management. It may be used to pull machinery, transport timber, carry equipment or perform operations such as harvesting, forwarding or maintaining forest land.

Forestry vehicles can include tractors, specialised self-propelled machines, trailers and interchangeable equipment. Their registration, driving-licence requirements, maximum speed, road access and technical requirements depend on the vehicle's legal classification and the local traffic regulations.

74. Construction vehicle

A construction vehicle is a vehicle or mobile machine designed or adapted for work connected with construction, roadworks, excavation, lifting or the movement of materials. Examples include excavators, loaders, bulldozers, road rollers, mobile cranes, dump trucks and concrete mixers.

Construction vehicles vary greatly in size, speed and legal classification. Some are ordinary road vehicles, while others are specialised machines intended mainly for use on construction sites. When travelling on public roads, they must comply with the applicable registration, licensing, lighting, dimensions, weight, speed and traffic rules.

75. 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.
