1. Colombia
Colombia occupies the northwestern corner of South America, with coastlines on both the Caribbean Sea and Pacific Ocean and the Andes dividing into several mountain ranges across the country. Traffic drives on the right. Intercity journeys frequently involve steep gradients, long descents and winding mountain roads, while periods of intense rainfall can cause landslides, flooding and temporary road closures. Driving conditions therefore vary considerably between major cities, high-altitude Andean routes and lower tropical regions.
Colombia has a national traffic code, but cities can impose local circulation measures such as Pico y Placa, which restricts vehicles according to registration plates and schedules. There is no nationwide vignette; many major roads use toll plazas, and the interoperable Colpass system allows electronic toll payment with an RFID tag. National law generally caps urban roads at 50 km/h, school and residential zones at 30 km/h and national or departmental roads at 90 km/h, while qualifying divided roads can allow up to 120 km/h. Written road information is primarily in Spanish.

What is the alcohol limit for drivers in Colombia?
Colombia does not use a simple permitted BAC limit in the usual sense. Administrative drink-driving sanctions begin at 20 mg of ethanol per 100 ml of blood (0.02%), classified as grado cero de alcoholemia. The practical rule is therefore not to drink before driving.
What speed limits apply to passenger cars in Colombia?
Built-up areas: The competent local authority sets and signs the limit, but the general national ceiling is 50 km/h on urban roads and municipal roads. Lower limits are common and must be followed.
School and residential zones: The national maximum in school and residential zones is 30 km/h.
National and departmental roads: The road authority determines and signs the applicable speed according to the road, but the general national ceiling is 90 km/h, subject to the specific divided-road exception and other legally established arrangements.
Divided roads: On a divided road with no pedestrian crossings incorporated into its design, the legal maximum can be 120 km/h. This is not a universal motorway limit, so always follow the posted speed.
Are seat belts compulsory in Colombia?
Yes. The driver and front-seat passengers must wear seat belts on all roads. Rear-seat belt use is also compulsory in vehicles manufactured from 2004 onward, according to the applicable regulations.
Can you use a mobile phone while driving in Colombia?
Using a mobile communication system or phone while driving is prohibited unless it is used with hands-free accessories or auxiliary equipment. Handling the phone while driving should therefore be avoided.
What safety equipment must a car carry in Colombia?
The mandatory road kit includes items such as two warning triangles or flashing yellow warning lamps, a first-aid kit and a fire extinguisher. The statutory equipment list also includes a jack, wheel wrench, two wheel chocks, basic tools, a spare tyre and a flashlight.
Can young children sit in the front seat in Colombia?
Children under 10 may not travel in the front seat. The Traffic Code also requires a securely fixed rear-seat safety seat for a child under two travelling only with the driver. Use an appropriate restraint and follow the applicable vehicle rules.

2. Speed limit
A speed limit is the maximum legal speed permitted on a road, lane or within a designated area. It may be established by general traffic law or indicated by fixed, variable or temporary traffic signs.
A speed limit is a maximum, not a target speed. Drivers must travel more slowly whenever traffic, visibility, weather, road conditions, vulnerable road users or the condition of the vehicle make the maximum permitted speed unsafe.
Wikimedia.org • EEIM • CC BY
Which general speed limits should car drivers know in Colombia?
Colombian authorities set and sign road-specific limits within national ceilings. These are generally 50 km/h on urban and municipal roads, 30 km/h in school and residential areas, and 90 km/h on national and departmental roads. Qualifying divided roads without pedestrian crossings incorporated into their design may permit up to 120 km/h. This does not establish a universal 120 km/h motorway limit.
Start of a speed limit.
English • Traffic sign SR-30 • Maximum permitted speed: 60 km/h. Sets a 60 km/h maximum. Travel slower when conditions require.
Español • SR-30 • Velocidad máxima permitida: 60 km/h. Establece una velocidad máxima de 60 kilómetros por hora. Circula a una velocidad menor cuando las condiciones lo exijan.

Does Colombia’s 120 km/h exception cover every divided road?
No. The statutory exception concerns qualifying divided roads with no pedestrian crossings incorporated into their design. The competent authority determines and signs the applicable speed. A divided layout alone is not permission to accelerate to 120 km/h.
Is the Colombian school or residential maximum the ordinary 50 km/h urban ceiling?
No. The national maximum in school and residential areas is 30 km/h. A lower road-specific limit remains binding, and pedestrians or visibility can require a speed below that maximum.
3. Pedestrian warning
A pedestrian warning is a traffic warning indicating that pedestrians may be crossing or entering the roadway ahead. It is commonly used near pedestrian crossings or other locations where drivers need advance notice of frequent pedestrian activity.
Drivers approaching a pedestrian warning should reduce speed when necessary, watch carefully for pedestrians and be prepared to stop. The design of the warning sign and the priority rules at the crossing vary between countries.
Wikimedia.org • Petruss • CC BY-SA
How should I react to a pedestrian warning in Colombia?
Reduce speed, look along both sides of the road and be ready to stop. The warning identifies a pedestrian hazard ahead; children, people with limited mobility or others may enter the road unexpectedly.
Does a pedestrian warning in Colombia identify the crossing itself?
Not necessarily. An advance warning alerts you to danger ahead. The actual crossing is identified by its own signs, markings or signals. Apply the crossing rules when you reach it, and follow any supplementary distance information.
Warning for pedestrians.
English • Traffic sign SP-46 · family • Pedestrian area. Pedestrians may be present. Reduce speed and watch for people entering the carriageway. The drawing has a yellow background; the current manual requires fluorescent yellow-green. The family is identified without claiming compliance of the colour shown.
Español • SP-46 · familia • Zona de peatones. Advierte una zona con presencia de peatones. Reduce la velocidad y presta atención a quienes puedan entrar en la calzada. El dibujo tiene fondo amarillo. El manual vigente exige amarillo verde fluorescente para esta señal; se identifica la familia, sin afirmar conformidad del color mostrado.

What should drivers know about pedestrian crossings in Colombia?
Drivers must respect pedestrian safety, crossings and traffic signals. Give particular protection to children, elderly people and people with disabilities. A warning sign does not remove the pedestrian duties in the National Traffic Code.
4. Slope
A slope is a section of road that rises or descends noticeably. A steep slope can affect vehicle speed, braking distance, traction, visibility and the ability of heavy or low-powered vehicles to maintain a steady speed.
Warning signs may indicate a steep ascent or dangerous descent and may show the gradient as a percentage. Drivers should adjust their speed early, select a suitable gear and remain prepared for slow vehicles, bends and changing road conditions.
Wikimedia.org • EEIM • CC BY-SA
What does a steep-slope warning mean in Colombia?
Colombian warnings identify steep-road hazards. The Traffic Code expressly requires reducing speed on steep descents and where visibility is limited.
Warning for a steep descent.
English • Traffic sign SP-27 · family • Steep descent. Reduce speed and control the descent to avoid overheating the brakes. The drawing gives no gradient percentage and is mirrored relative to the manual's example. The descent warning is identified without assigning a numerical gradient.
Español • SP-27 · familia • Pendiente fuerte de descenso. Advierte una pendiente fuerte de descenso. Reduce la velocidad y controla el descenso para evitar el recalentamiento de los frenos. El dibujo no indica el porcentaje de la pendiente y está orientado en espejo respecto al ejemplo del manual. Se identifica la advertencia de descenso, sin asignar una pendiente numérica.

How should I approach a steep descent in Colombia?
Reduce speed before the descent and select a suitable gear to help control the vehicle. Keep enough following distance and avoid building up speed that requires continuous heavy braking. A warning gives no fixed safe descent speed: the gradient, surface, visibility, load and vehicle can require a speed well below the legal maximum.
What should I check when meeting or overtaking on a slope in Colombia?
Do not overtake where a crest prevents a clear view. Follow the actual signs and meeting rules and use a suitable safe place rather than entering a narrow section in conflict with an oncoming vehicle.
5. Bus stop
A bus stop is a designated place where buses stop to allow passengers to board or leave. It may be identified by a sign, shelter, raised platform, road marking or other public-transport infrastructure and can be located beside the road or in a specially constructed stopping area.
Drivers approaching a bus stop should watch carefully for buses, pedestrians and passengers crossing or entering the roadway. Parking or stopping restrictions may apply around bus stops to keep the area accessible and visible.
Wikimedia.org • Remux • CC BY-SA
What stopping or parking restrictions apply at bus stops in Colombia?
Colombia prohibits parking on roads and areas reserved for the specified public-transport use. Read the actual paradero and the traffic authority’s stopping and parking controls.
🔗 cancilleria.gov.co • Colombia Ministry of Foreign Affairs, National Traffic Code
May I briefly drop off a passenger at a bus stop in Colombia?
A passenger pick-up must use a lawful location and must not obstruct a reserved stop, lane or footway. A taxi or private car is not automatically entitled to wait at every public-transport stop.
🔗 cancilleria.gov.co • Colombia Ministry of Foreign Affairs, National Traffic Code
What should I do near a stopped bus in Colombia?
Keep a safe speed and clearance and watch for passengers. Apply the Traffic Code and the local scheme for the bus’s return to traffic rather than assuming an unconditional bus priority.
🔗 cancilleria.gov.co • Colombia Ministry of Foreign Affairs, National Traffic Code
6. Stop sign
A stop sign requires drivers to bring their vehicle to a complete stop and give way before entering or crossing the road ahead. The stop must be made at the stop line or another legally prescribed position.
After stopping, the driver may continue only when this can be done safely and without interfering with traffic that has priority. The sign does not create priority for the driver who has stopped.
Wikimedia.org • Elberth_00001939 • CC BY-SA
Must I stop completely at a stop sign in Colombia?
Yes. Come to a complete stop when the applicable stop sign controls your approach, even when you cannot see another road user. Slowing to a crawl is not a stop. The Colombian stop indication uses PARE.
🔗 cancilleria.gov.co • Colombia, National Traffic Code, Law 769/2002, compiled text
Stop and give way.
English • Traffic sign SR-01 • Stop. Stop completely. Proceed only when you can join or cross safely.
Español • SR-01 • Pare. Detén completamente el vehículo. Reanuda la marcha solo cuando puedas incorporarte o cruzar con seguridad.

Where must I stop at a stop-controlled junction in Colombia?
Stop at the indicated line or prescribed stopping position before entering the conflicting route. Check pedestrians, cyclists and priority traffic; do not move off merely because your vehicle has stopped once.
🔗 cancilleria.gov.co • Colombia, National Traffic Code, Law 769/2002, compiled text
Does stopping first give me priority at a stop sign in Colombia?
A complete stop does not, by itself, give you priority. Give way to the road users entitled to pass under the junction’s signs and rules, check pedestrians and cyclists, and proceed only when the gap is safe. Do not follow another stopped vehicle through without satisfying your own stopping and yielding duties.
🔗 cancilleria.gov.co • Colombia, National Traffic Code, Law 769/2002, compiled text
7. School area
A school area is a road or group of roads near a school where large numbers of children may walk, cycle, cross the road or enter and leave vehicles. It may be identified by warning signs, zone signs, road markings, traffic-calming measures or flashing lights.
Special speed limits, parking restrictions or access rules may apply permanently or only during school arrival and departure times. Drivers should reduce speed, watch carefully for children and be prepared to stop.
Wikimedia.org • EEIM • CC BY-SA
What speed rules apply around schools in Colombia?
Colombia’s national maximum in school and residential zones is 30 km/h. Follow any lower restriction imposed and signed by the responsible authority.
Does a school warning sign in Colombia automatically set the speed limit?
A children or school warning alerts you to a potential hazard; the enforceable numerical speed limit depends on the applicable law, regulatory signs and any time or variable display. Slow further if children are near the road.
Warning for children.
English • Traffic sign SP-47 · family • School zone. A school and possible pupils are nearby. Reduce speed and pay particular attention to pedestrians. The drawing is a yellow diamond; the current manual shows a fluorescent yellow-green pentagonal school sign. The family is identified without claiming this design complies.
Español • SP-47 · familia • Zona escolar. Advierte la proximidad de una escuela y la posible presencia de escolares. Reduce la velocidad y presta especial atención a los peatones. El dibujo es un rombo amarillo. El manual vigente muestra una señal escolar pentagonal de amarillo verde fluorescente; se identifica la familia Zona escolar, sin afirmar conformidad de este diseño.

How should you pass a school entrance in Colombia?
Watch for children stepping out from between parked vehicles, obey crossings and any school patrol, and follow stopping or parking restrictions. Do not obstruct visibility near a crossing or school entrance; approach at a speed that permits a safe stop.
8. Crossing animals
An animals-crossing warning indicates a place or road section where wild animals, livestock or ridden animals may enter or cross the road. Animals may appear suddenly, move unpredictably or be difficult to see in darkness, vegetation or poor weather.
Drivers should reduce speed, scan both sides of the road and remain prepared to stop. The warning sign does not itself give animals priority or impose a numerical speed limit, but drivers must avoid frightening, endangering or colliding with them.
Wikimedia.org • Germarquezm • CC BY-SA
Which animals might drivers encounter on roads in Colombia?
Depending on the locality, drivers may meet livestock and wildlife along mountain or rural routes. Roadside animal-warning signs and local hazard information indicate where extra care may be needed; do not assume the hazard ends immediately after a sign.
Warning for cattle on the road.
English • Traffic sign SP-49 • Animals on the road. Animals may be present; this drawing shows livestock. Reduce speed and be prepared to stop.
Español • SP-49 • Presencia de animales en la vía. Advierte la posible presencia de animales en la vía; en este dibujo, ganado. Reduce la velocidad y prepárate para detenerte.

Does an animal-crossing warning sign in Colombia set a new speed limit?
A warning of animals is not, by itself, a numerical speed-limit sign. Continue to obey the applicable speed limit, but slow down whenever animals could enter the road or visibility is poor. A separate regulatory speed sign must also be obeyed.
What should you do if an animal enters the road in Colombia?
Ease off the accelerator, assess the traffic behind and brake smoothly if necessary. Avoid abrupt swerving into opposing traffic or off the road. Give farm animals and ridden animals room, avoid frightening them with unnecessary horn use, and be alert for more animals following.
9. Traffic lights
Traffic lights use coloured lights, arrows or symbols to regulate when road users may proceed, must prepare to stop or must remain stopped. Separate signals may apply to particular directions, lanes, pedestrians, cyclists or public-transport vehicles.
A green light permits movement only when the route is clear and the movement is otherwise legal. Road users must still follow priority rules, turning restrictions, lane markings and instructions from authorised traffic controllers.
Wikimedia.org • XalD • CC BY-SA
What must a driver do at red, amber and green signals in Colombia?
On red, stop without invading the start of the pedestrian-crossing area; if it is unmarked, article 118 treats it as extending two metres from the signal. Do not enter the junction on amber, start moving or accelerate during amber; if already inside, finish clearing it. Green remains subject to pedestrian priority and keeping the junction clear.
🔗 cancilleria.gov.co • Colombia, National Traffic Code, Law 769/2002, compiled text
May you turn at a red traffic light in Colombia?
Article 118 generally permits a right turn on red unless it is prohibited by special signage. Stop first, respect pedestrian priority and proceed only without endangering pedestrians or other traffic. Follow any applicable local traffic-authority controls; this permission does not authorise a left turn on red.
🔗 cancilleria.gov.co • Colombia, National Traffic Code, Law 769/2002, compiled text
Can a green light remove the need to give way to pedestrians in Colombia?
No. A green signal is not a guarantee that the junction is empty. Check for people already crossing, vehicles completing a movement and any separate pedestrian, bicycle or turning signals. Do not enter if you cannot clear the junction safely.
🔗 cancilleria.gov.co • Colombia, National Traffic Code, Law 769/2002, compiled text
10. Reversing
Reversing means driving a vehicle backwards. It is commonly used when parking, leaving a confined space or repositioning a vehicle where forward movement is not practical.
Before reversing, the driver should check mirrors and blind spots, look carefully around the vehicle and make sure the area behind is clear. Reversing should be performed slowly and only for as long as necessary because visibility behind the vehicle is often limited.
Wikimedia.org • Kārlis Dambrāns • CC BY
When may Colombian drivers reverse on public roads?
Only for parking or emergencies.
11. 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.
Wikimedia.org • EEIM • CC BY-SA
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.
12. 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.

13. 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 • Pedro_Felipe • 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.
14. 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
15. 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
16. 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.
17. 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.

18. 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.

19. 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.

20. 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.
21. 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.

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.

22. 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.

23. 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.

What is a forestry vehicle?
A forestry vehicle is a vehicle designed or adapted for forestry work, such as pulling machinery, carrying equipment, transporting timber or working on forest land.
Do forestry vehicles have special speed limits?
They may. The permitted speed can depend on the vehicle's construction speed, mass, road type and local traffic rules. Posted speed limits must also be respected.
Can forestry equipment extend beyond the normal width of the vehicle?
Yes. Machinery and attached implements can make a forestry vehicle unusually wide or long. Check the applicable dimensions and special-vehicle rules before using the road. British guidance, for example, includes attached implements in width checks and describes extra arrangements for wide agricultural or forestry vehicles.

24. 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.

What is a construction vehicle?
A construction vehicle is a vehicle or mobile machine used for construction, excavation, lifting, roadworks or transporting construction materials.
Do construction vehicles have special speed limits?
They may. The permitted speed can depend on the vehicle’s design, mass, legal category and the road. Do not assume that a construction machine has the same limit as a car; follow both the road limit and any lower vehicle-specific limit.
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.
25. 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.
