26. Location marker

A location marker is a roadside reference showing a measured position along a road. It normally identifies a kilometre, mile or smaller interval measured from an established starting point on that route.

Kilometre and hectometre markers help road users, emergency services, road authorities and maintenance crews identify an exact section of road. They do not impose a speed limit, priority rule or access restriction.

What does a roadside location marker tell you in Malaysia?

Where used, a roadside reference marker gives a measured position along a particular road, usually as a kilometre or other chainage reference. Designs and units are determined by the local road authority; the number is not automatically a distance to the next destination.

27. Traffic mirror

A traffic mirror is a convex mirror installed near an intersection, driveway, bend or other location with restricted visibility. Its curved surface provides a wider view of approaching road users than an ordinary flat mirror.

A traffic mirror is only a visibility aid. It may distort distance, speed and direction and may be affected by darkness, weather, dirt or damage. Drivers must continue to observe the road directly, obey all priority rules and proceed only when it is safe.

What is a traffic mirror?

A traffic mirror is a roadside visibility aid that can help users see around a blind corner or obstruction. It gives an indirect view, which may be restricted or distorted; it does not replace checking whether it is safe to proceed.

🔗 monmouthshire.gov.uk • Monmouthshire Council, roadside visibility mirrors

🔗 devon.gov.uk • Devon County Council, mirrors on the highway

🔗 hse.gov.uk • HSE, vehicle-route visibility and mirrors

Does a traffic mirror show an exact image?

No. The reflected image can be distorted, and glare, bad weather or dirt can restrict the view. Judging an approaching vehicle’s speed from a mirror can be difficult. Do not rely on the mirror alone.

28. Disabled parking

Disabled parking refers to parking spaces and parking privileges reserved for people with disabilities who meet the applicable eligibility requirements. Reserved spaces are normally identified by the international wheelchair symbol and are positioned to provide easier access to nearby facilities.

Use of a disabled parking space generally requires a valid disabled parking permit or card. The permit normally belongs to the eligible person rather than to a particular vehicle and may only be used when that person is driving or travelling in the vehicle.

29. 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.

What should you check before reversing?

Check behind and around the vehicle for pedestrians, cyclists, other vehicles and obstacles. Use mirrors and cameras where available, but also look directly because monitoring systems can have blind spots.

🔗 wetten.overheid.nl • Vienna Convention on Road Traffic, Article 14; international framework subject to national law

🔗 gov.uk • Great Britain Highway Code, Rules 200–203; national guidance example

Should you reverse for a long distance?

No. Reversing should normally be limited to the distance necessary to complete the manoeuvre safely. Driving forward generally provides better visibility and vehicle control.

30. Uncontrolled crossroad

An uncontrolled crossroad is an intersection where traffic priority is not specifically regulated by traffic lights, an authorised person or signs assigning priority to particular approaches. Drivers must therefore determine who has priority using the default traffic rules that apply in that country.

The applicable rule varies between countries and may include priority from the right, priority from the left or another default right-of-way rule. Drivers should approach an uncontrolled crossroad carefully, observe traffic from every direction and never assume that a wider or busier road automatically has priority.

What is an uncontrolled crossroad?

An uncontrolled crossroad is an intersection where priority is not specifically assigned by traffic lights, an authorised person or priority signs. Drivers must use the default priority rules of the country.

🔗 wetten.overheid.nl • Vienna Convention on Road Traffic, Article 18; international framework subject to national law

🔗 wetten.overheid.nl • Vienna Convention on Road Signs and Signals, Annex 1, section A.18; sign-system reference

Who has priority at an uncontrolled crossroad?

This depends on the local traffic law. Some countries use priority from the right, while others use different rules. Drivers should know the default intersection rule of the country in which they are driving.

🔗 wetten.overheid.nl • Vienna Convention on Road Traffic, Article 18; international framework subject to national law

🔗 wetten.overheid.nl • Vienna Convention on Road Signs and Signals, Annex 1, section A.18; sign-system reference

What should you do if you are unsure who has priority?

Reduce speed and be prepared to stop. Never force your way through an intersection simply because the priority situation is unclear.

31. Road surface

A road surface warning indicates that the road ahead may be uneven, damaged or in poor condition and could affect the stability, steering or braking of a vehicle. The hazard may include bumps, depressions, potholes, broken pavement or other irregularities in the road surface.

Drivers should reduce speed where necessary, maintain a safe distance and avoid sudden steering or braking when passing over an irregular surface. The exact meaning and appearance of the warning sign vary between countries, so drivers must follow the local traffic signs and regulations.

32. Emergency exit

An emergency exit is a marked escape route that allows road users to leave a tunnel or other enclosed traffic facility during a serious incident such as a fire, smoke development or another emergency. Emergency exits lead towards a safer area separated from the immediate danger.

In an emergency, occupants should leave their vehicle when evacuation is necessary and follow the emergency-exit signs and instructions. They should move away from the danger rather than remaining inside the tunnel or returning to their vehicle.

35. 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.

40. 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.

41. 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.

42. 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.

43. 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.

44. 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.

45. 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.

46. 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.

47. 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.

48. 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.

49. 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.

50. 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.

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.

🔗 gov.uk • Great Britain Highway Code, Rules 59–82, cycling; national guidance example

What is the difference between a speed pedelec and an ordinary electric bicycle?

The assistance cut-off differs. For example, Belgium’s ordinary pedal-assisted cycle category uses a 25 km/h cut-off, while a speed pedelec can provide assistance up to 45 km/h. These are assistance and classification rules, not a universal maximum speed every bicycle can physically reach.
