A crossing guard is a person who assists pedestrians in crossing a road safely, often near schools or other locations with frequent pedestrian activity.

It depends on local law. In some countries authorised crossing guards have the legal power to stop traffic using a prescribed sign or signal, while other helpers may only assist pedestrians without directing drivers.

Drivers should slow down, remain attentive and obey authorised stop signals so that pedestrians can cross safely.

Motorail is a train service that transports passengers and their vehicle together, with the vehicle carried on specialised railway wagons.

Depending on the operator and route, Motorail services may carry cars, motorcycles or other eligible road vehicles. Size and weight restrictions may apply.

No. Passengers normally leave their vehicle after loading and travel separately in the passenger accommodation provided by the train.

A snowplough is a vehicle fitted with equipment designed to remove snow from roads or other paved surfaces.

Yes. Many winter-maintenance vehicles can combine snow removal with equipment that spreads salt, grit or other substances used to improve road conditions.

Keep a safe distance, reduce speed and avoid unnecessary overtaking. Snow or road-treatment material may be thrown from the vehicle and visibility may be reduced.

A parking violation occurs when a vehicle is parked in a way that does not comply with the applicable traffic rules, signs, markings or parking conditions.

Examples include parking where prohibited, blocking a sidewalk or crossing, using a reserved space without permission, failing to pay or exceeding a permitted parking time.

Depending on local law and the offence, the vehicle owner or driver may receive a fine, parking charge or other enforcement measure, and a dangerously or illegally parked vehicle may sometimes be removed.

km/h is the abbreviation for kilometres per hour, a unit used to measure speed.

A speed of 50 km/h means that, if the speed remained constant, the vehicle would travel 50 kilometres in one hour.

No. km/h measures speed in kilometres per hour, while mph measures speed in miles per hour. The two units therefore represent different numerical speeds.

mph is the abbreviation for miles per hour, a unit used to measure speed.

A speed of 50 mph means that, if the speed remained constant, the vehicle would travel 50 miles in one hour.

No. mph measures speed in miles per hour, while km/h measures speed in kilometres per hour. 1 mph is approximately 1.61 km/h.

A speedometer is an instrument that displays the current speed of a vehicle.

It is normally located on the vehicle's instrument panel or digital driver display, where it can be seen easily while driving.

A speedometer may display speed in kilometres per hour (km/h), miles per hour (mph) or both, depending on the vehicle and market.

A national speed limit is a default maximum speed established by law for particular roads or vehicles when no different local restriction applies.

No. A country may have different general limits for motorways, rural roads and built-up areas, and some countries allow regional authorities to establish different default limits.

Yes. A posted regulatory speed limit may impose a lower or, where legally permitted, higher maximum speed than the general limit for that road.

A rumble strip is a textured or raised road-surface feature that produces vibration and noise when a vehicle passes over it.

They are used to alert drivers to hazards, approaching road features or unintended movement out of a traffic lane.

Not by itself. A rumble strip warns or attracts attention, while any legally binding speed restriction must be established by the applicable traffic rules or regulatory signs.

Ride height describes how high a vehicle's body or chassis sits above the road surface.

Ride height can be affected by the suspension, wheel and tyre dimensions, vehicle load and suspension modifications.

Yes. Suspension modifications can lower or raise a vehicle, but such modifications may be subject to technical approval, inspection and safety requirements.

A dirt road is an unpaved road surfaced mainly with natural soil or compacted earth.

A dirt road mainly uses the natural earth or soil as its driving surface, while a gravel road normally has a deliberately added layer of gravel or crushed stone.

Use a suitable speed, increase following distance when necessary and accelerate, brake and steer smoothly. Extra care may be required when the surface is dusty, muddy, rutted or uneven.

Driving is the act of controlling and operating a vehicle while travelling in traffic.

Safe driving requires proper vehicle control, attention to the road, compliance with traffic rules and appropriate reactions to other road users and changing conditions.

The requirements vary by country and vehicle type. Drivers may need to meet minimum-age, driving-licence, medical-fitness and vehicle-category requirements.

A start-stop system automatically switches off the engine when the vehicle is stationary and restarts it when the driver is ready to continue.

The system is primarily intended to reduce unnecessary engine idling, particularly when a vehicle is waiting in traffic.

Not necessarily. The system may keep the engine running when operating conditions do not allow an automatic stop, depending on the vehicle and its systems.

A manual transmission is a gearbox in which the driver manually selects the appropriate gear, normally using a gear lever and clutch pedal.

The clutch temporarily disconnects the engine from the transmission, allowing the driver to start, stop and change gears smoothly.

With a manual transmission, the driver selects and changes gears. An automatic transmission normally selects the appropriate gears automatically without requiring a conventional clutch pedal.

An automatic transmission is a gearbox that automatically selects and changes gears without requiring the driver to operate a conventional clutch pedal.

With an automatic transmission, gear changes are handled automatically, while a manual transmission normally requires the driver to operate a clutch and select each gear manually.

No. Different designs include conventional automatic transmissions, continuously variable transmissions and dual-clutch systems, although they can all operate without the driver manually controlling a clutch during normal driving.

A throttle is a control that regulates how much power an engine or motor produces.

In most cars, the throttle is controlled using the accelerator pedal. Motorcycles and some other vehicles commonly use a twist-grip throttle.

They are closely related but not exactly the same. The accelerator is the driver's control, while the throttle refers more broadly to the system that responds to that input and regulates engine or motor power.

A tachometer is an instrument that measures and displays the rotational speed of an engine or motor, usually in revolutions per minute.

RPM means revolutions per minute and indicates how many complete rotations the engine's crankshaft makes in one minute.

No. A tachometer shows engine rotational speed, while a speedometer shows the vehicle's road speed.

A steering wheel is the driver's main control for changing the direction in which a vehicle travels.

Turning the steering wheel operates the vehicle's steering system, which changes the direction of the steered wheels.

Normally, no. Steering should be smooth and controlled because sudden movements can destabilise the vehicle or create danger for other road users.

Power steering is a system that assists the driver's steering effort, making the steering wheel easier to turn.

Vehicles may use hydraulic, electro-hydraulic or electric power steering, depending on their design.

Steering may become considerably heavier or a warning may appear. The driver should maintain control, reduce speed safely and have the steering system checked as soon as possible.

Scanning means continuously observing different parts of the traffic environment so that hazards and changes can be detected early.

A driver should regularly observe the road ahead, mirrors, intersections, side areas, vulnerable road users and relevant blind spots.

Scanning helps drivers identify hazards earlier and gives them more time to adjust speed, position or direction safely.

A vehicle mirror allows the driver to observe traffic and other road users behind or beside the vehicle.

An interior rear-view mirror normally provides a view through the rear window, while exterior side mirrors provide views along the sides and towards the rear of the vehicle.

Check your mirrors regularly and particularly before changing speed or direction, changing lane, overtaking, merging, turning or stopping.

Yes. Mirrors should be adjusted from the normal driving position before setting off so that they provide the intended view of traffic behind and beside the vehicle.

No. Even correctly adjusted mirrors can leave areas that are not visible to the driver. These are commonly called blind spots.

Yes. Where necessary, use a brief direct observation in addition to the mirrors before moving sideways so that a cyclist, motorcycle or other vehicle hidden from the mirrors is not overlooked.

Yes. A cracked, loose, missing or badly adjusted mirror can reduce the driver's view of surrounding traffic and should be repaired or replaced when necessary.

Some vehicles use approved camera-based indirect-vision systems instead of or in addition to conventional mirrors. Whether such a system is legally permitted depends on the vehicle's approval and local technical requirements.

Checking the mirrors can help detect cyclists, motorcyclists and other approaching road users before a door is opened into their path.

Yes, according to the applicable vehicle requirements. Motorcycles normally have one or more rear-view mirrors so that the rider can observe traffic behind without turning around for extended periods.

Common fuels include petrol, diesel, LPG and CNG. Some vehicles can also use biofuels or other alternative fuels, while electric vehicles obtain their energy from a battery rather than conventional fuel.

Check the vehicle manufacturer's instructions and the fuel information shown near the filler opening or on the vehicle. Fuel pumps are normally labelled to help drivers identify compatible fuels.

Smooth acceleration, anticipating traffic, maintaining an appropriate speed, correct tyre pressure, avoiding unnecessary loads and keeping the vehicle properly maintained can help reduce fuel consumption.

Good fuel economy means that a vehicle uses relatively little fuel for the distance travelled. When consumption is expressed in litres per 100 kilometres, a lower number generally indicates better fuel economy.

Smooth acceleration, maintaining a steady appropriate speed, anticipating traffic, avoiding unnecessary braking and acceleration, and selecting an efficient gear can all help reduce fuel consumption.

Fuel economy can be affected by tyre pressure, vehicle weight, roof racks, mechanical condition, air conditioning and other electrical loads. Proper maintenance and removing unnecessary loads can improve efficiency.

A fuel gauge shows the approximate amount of fuel remaining in the vehicle's tank. Most gauges use a scale between empty and full.

The low-fuel warning light indicates that the amount of fuel remaining has reached a low level. The driver should refuel soon rather than relying on the remaining reserve.

No. A fuel gauge provides an approximate reading. The indicated level can vary because of vehicle movement, road gradient, tank shape and the design of the fuel-level sensor.

Petrol is a liquid motor fuel used mainly in spark-ignition engines. It is called petrol in many countries and may contain ethanol or other renewable components.

The octane rating indicates the fuel's resistance to uncontrolled combustion or engine knocking. Vehicles should use petrol with at least the octane rating specified by the manufacturer.

E5 and E10 indicate the permitted ethanol content of petrol. E5 contains up to 5% ethanol by volume, while E10 contains up to 10%. Drivers should check whether their vehicle is compatible with the selected fuel.
