126. Disability

Disability refers to a physical, sensory, intellectual or other long-term condition that, together with environmental or accessibility barriers, may affect how a person participates in everyday activities. In road traffic, people with disabilities may participate as pedestrians, drivers, cyclists, passengers or users of mobility devices.

Road systems should take account of accessibility, safe crossings, suitable parking and sufficient time and space for people with different mobility or sensory needs. Drivers should take particular care around road users who may require additional time or space to travel safely.

Must drivers take extra care around people with disabilities in Belgium?

Yes. Drivers must be especially cautious around people with disabilities and must slow down and, if necessary, stop.

Can people with disabilities obtain a special parking card in Belgium?

Yes, when they meet the applicable eligibility conditions. The official parking card allows its holder to use parking spaces reserved for people with disabilities and provides additional parking benefits under the applicable rules.

Can another person use a Belgian disability parking card?

The card is personal to its holder. It may be used when the holder is travelling in the vehicle, either as the driver or as a passenger, but it may not be used when the holder is not present.

127. Motorail

Motorail is a rail service that transports passengers together with their car, motorcycle or other eligible vehicle on the same journey. The passengers normally travel in passenger coaches or sleeping accommodation while their vehicle is carried on dedicated vehicle-transport wagons.

Motorail services are mainly intended for long-distance travel, allowing travellers to avoid driving the entire route while still having their own vehicle available at their destination. Vehicle dimensions, loading procedures and eligible routes depend on the operator.

Can you currently take your car on a Motorail train from Belgium?

No current vehicle-transport service is offered from Belgium by Nightjet. Passengers travelling from Belgium can use international rail services, but their car or motorcycle cannot currently be loaded onto those Belgian Nightjet connections.

Does SNCB's train-and-car service carry cars on trains?

No. SNCB's current train-and-car services are designed to combine rail travel with facilities such as station car parking or car rental, rather than transporting the passenger's own vehicle on the train.

Can Belgian travellers use Motorail services elsewhere in Europe?

Yes, where an operator still offers vehicle transport. Travellers can first reach a suitable Motorail departure point by another route and then use a connection on which vehicle transport is available, subject to the operator's vehicle and booking requirements.

128. km/h

km/h means kilometres per hour and is a unit used to measure speed. It expresses how many kilometres a vehicle or other moving object would travel in one hour if it maintained the same speed.

For example, a speed of 50 km/h means travelling at a rate of 50 kilometres per hour. Kilometres per hour are widely used for road speeds and speed limits in countries that use the metric system.

Which speed unit is used on Belgian roads?

Belgium uses kilometres per hour (km/h) for road speeds and speed limits.

What does the number on a Belgian speed-limit sign mean?

The number on a C43 speed-limit sign indicates the maximum permitted speed in kilometres per hour. For example, a C43 sign displaying 50 means that drivers may not exceed 50 km/h.

Does a Belgian speed-limit sign have to display 'km/h'?

No. The number on a C43 sign is understood as a speed in kilometres per hour. Under the current Belgian Road Code, displaying the abbreviation 'km' on the sign is optional.

129. mph

mph means miles per hour and is a unit used to measure speed. It expresses how many miles a vehicle or other moving object would travel in one hour if it maintained the same speed.

For example, a speed of 50 mph means travelling at a rate of 50 miles per hour. One mile per hour is approximately 1.61 km/h, so speeds expressed in mph and km/h have different numerical values.

Does Belgium use mph for road speeds?

No. Belgian road speeds and speed limits are expressed in kilometres per hour (km/h), not miles per hour.

Do Belgian speed-limit signs show mph?

No. The number displayed on a Belgian C43 speed-limit sign represents the maximum permitted speed in kilometres per hour.

What should you do if your vehicle's speedometer also shows mph in Belgium?

When driving in Belgium, you must compare your speed with the applicable limit in km/h. If your speedometer displays both units, use the km/h scale when interpreting Belgian speed limits.

130. Speedometer

A speedometer is an instrument in a vehicle that shows the vehicle's current speed. It is normally displayed on the instrument panel and may use an analogue dial, a digital display or both.

Drivers should use the speedometer to monitor their speed and remain within the applicable speed limit. The displayed unit is usually kilometres per hour or miles per hour, depending on the country and vehicle.

Must cars have a speedometer in Belgium?

Yes. Vehicles subject to the applicable technical approval requirements must be equipped with a functioning speedometer.

Which unit must a Belgian speedometer show?

The speedometer must provide a speed indication in kilometres per hour (km/h). A vehicle may also display mph in addition to km/h.

Can a speedometer legally show less than the vehicle's true speed?

No. Under the applicable vehicle-approval requirements, the indicated speed must not be lower than the vehicle's actual speed. A permitted positive tolerance means the speedometer may indicate somewhat more than the true speed.

131. National speed

A national speed limit is a default maximum speed established by law for a particular type of road or vehicle when no lower or different local speed limit is indicated. National or general speed limits can differ according to whether the road is a motorway, rural road, built-up-area road or another road category.

Drivers should know the default speed limits that apply in the country or region where they are travelling and always obey any posted speed limit that overrides the general rule.

Does Belgium have one national speed limit?

No. Belgium has different general speed limits according to the road type, vehicle and region. Drivers must therefore know whether they are in Brussels, Flanders or Wallonia and follow any posted speed limits.

What are the general built-up-area speed limits in Belgium?

The general built-up-area limit is currently 30 km/h in the Brussels-Capital Region and 50 km/h in Flanders and Wallonia, unless signs impose or permit another speed.

Is there a Belgian national-speed-limit sign?

No dedicated sign simply meaning 'national speed limit applies' is used in the current Belgian system. When a local C43 speed restriction ends, an applicable end-of-restriction sign or the general rules for the road and region determine the speed that applies next.

132. Ride height

Ride height is the height at which a vehicle's body or chassis sits above the road surface. It is determined mainly by the suspension, wheels and tyres and can also change according to the vehicle's load.

Changing the ride height by lowering or raising the suspension can affect ground clearance, wheel alignment, handling and the space available between the vehicle and the road. Vehicle modifications must comply with the technical and approval rules that apply in the country.

Can you lower a car's ride height in Belgium?

Yes, under specific conditions. A category M1 passenger car may be lowered when the modification complies with the applicable Belgian technical requirements.

Must a lowered car be inspected in Belgium?

Yes. After the suspension has been lowered, the vehicle must undergo a specific technical inspection before it is used on the road again.

What is checked after lowering a car in Belgium?

The inspection includes checks of the modification and the vehicle's wheel geometry to verify that the wheel positions remain within the applicable technical requirements.

133. Dirt road

A dirt road is an unpaved road whose surface consists mainly of natural soil, earth or compacted ground rather than asphalt, concrete or an added gravel surface. Dirt roads are commonly found in rural, agricultural, forest and remote areas.

Drivers on dirt roads should adapt their speed to the surface conditions and avoid sudden braking, acceleration or steering. Dust, mud, ruts, potholes and reduced tyre grip can make driving more difficult, especially during or after bad weather.

How is a dirt or earth road defined in Belgium?

The Belgian Road Code defines an aardeweg as a public road that is wider than a path and is not laid out for vehicle traffic in general.

Who has priority when leaving an earth road in Belgium?

A driver coming from an earth road or path onto a public road with a carriageway must give way to every driver travelling on the road or carriageway being entered.

Does an earth road stop being an earth road if its entrance is paved in Belgium?

No. An earth road does not lose its legal status merely because the section where it connects with another public road has the appearance of a normal carriageway.

134. Driving

Driving is the act of controlling and operating a vehicle or other recognised means of transport in traffic. It involves steering, accelerating, braking, observing the road and interacting safely with other road users.

Safe driving requires the driver to remain in control, follow traffic rules and signals, observe surrounding traffic and adapt to road, weather and visibility conditions.

What must a driver be capable of doing in Belgium?

Every driver must be capable of driving and possess the necessary physical fitness, knowledge and driving skill. The driver must remain able to perform all necessary manoeuvres and keep the vehicle under control.

Must every moving vehicle have a driver in Belgium?

Yes. Every moving vehicle or vehicle combination must have a driver. Similar rules also apply to people controlling certain animals and livestock.

Can you use a handheld phone while driving in Belgium?

No. Unless the vehicle is stationary or parked, a driver may not use, hold or manipulate a mobile electronic device with a screen unless it is secured in a holder intended for that purpose.

135. Start-stop system

A start-stop system is a vehicle system that automatically switches off the engine when the vehicle is stationary and restarts it when the driver is ready to move again. It is commonly used in vehicles with combustion engines to reduce unnecessary engine idling.

The system normally operates automatically when certain conditions are met, such as when the vehicle stops in traffic. Its operation does not replace the driver's responsibility to control the vehicle safely and follow the applicable traffic rules.

Is a start-stop system required in Belgium?

No general requirement in the Belgian Road Code requires every vehicle to have a start-stop system. Whether a particular vehicle is equipped with one depends on its design and technical specifications.

Can you leave your engine idling unnecessarily in Belgium?

No. The Belgian Road Code states that drivers may not leave the engine running at idle except when this is necessary.

Does having a start-stop system change the Belgian idling rule?

No. A start-stop system can automatically switch off the engine while the vehicle is stationary, but the driver remains responsible for complying with the rules concerning unnecessary engine idling.

136. Manual transmission

A manual transmission is a vehicle transmission in which the driver selects the gears manually, usually using a gear lever together with a clutch pedal. The driver operates the clutch to disconnect and reconnect the engine from the transmission when starting, stopping or changing gears.

Driving a manual vehicle requires the driver to coordinate the clutch, accelerator and gear selection. Compared with an automatic transmission, gear changes are controlled directly by the driver rather than being performed automatically by the vehicle.

Can you drive a manual car with an automatic-only Belgian licence?

No. If category B on the driving licence carries code 78, the licence is restricted to vehicles with an automatic transmission.

How can you remove code 78 from a Belgian driving licence?

To remove the automatic-transmission restriction, the driver must pass a new practical driving examination with a manual-transmission vehicle.

Can a Belgian driver without code 78 drive both manual and automatic cars?

Yes. If the relevant driving-licence category is not restricted by code 78, the driver may operate both manual and automatic vehicles within that licence category.

137. Automatic transmission

An automatic transmission is a vehicle transmission that changes gears automatically without requiring the driver to operate a conventional clutch pedal and manually select each gear. Depending on the design, the driver normally selects positions such as park, reverse, neutral and drive while the transmission manages gear changes.

An automatic transmission can make driving simpler by removing the need to coordinate a clutch pedal and manual gear changes. Automatic transmissions include several different technologies, such as conventional automatics, continuously variable transmissions and dual-clutch systems.

How is an automatic vehicle defined for Belgian driving licences?

For driving-licence purposes, an automatic vehicle is one that does not have a clutch pedal, or the applicable manually operated clutch, that the driver must use when starting, stopping and changing gears.

What does code 78 mean on a Belgian driving licence?

Code 78 means that the relevant driving-licence category is restricted to vehicles with an automatic transmission.

How can you remove code 78 from a Belgian driving licence?

To remove the restriction, the driver must pass a new practical driving examination with a manual-transmission vehicle.

138. Throttle

A throttle is a control used to regulate the power produced by an engine or motor. In most cars and trucks, the driver controls the throttle through the accelerator pedal, while motorcycles commonly use a twist grip on the handlebar.

Increasing the throttle generally increases the power available for acceleration, while reducing it decreases the power delivered to the wheels. The exact system differs between combustion-engine, hybrid and electric vehicles.

Does the Belgian Road Code have a special rule for the throttle?

No separate traffic rule specifically defines the throttle. Its safe use forms part of the driver's general responsibility to maintain control of the vehicle.

Must a driver remain in control while accelerating in Belgium?

Yes. Every driver must remain capable of carrying out all necessary manoeuvres and must keep the vehicle under control at all times.

Can you repeatedly rev an idling engine in Belgium?

No. Belgian traffic rules prohibit a driver from repeatedly accelerating an engine while it is running in neutral. Unnecessary engine idling is also prohibited.

139. Tachometer

A tachometer is an instrument that shows the rotational speed of an engine or motor, usually measured in revolutions per minute (RPM). It is commonly displayed on the vehicle's instrument panel near the speedometer.

A tachometer helps the driver understand how fast the engine is rotating and can assist with selecting an appropriate gear in vehicles with a manual transmission. It measures engine speed rather than the vehicle's road speed.

What does a tachometer show in a Belgian vehicle?

A tachometer shows the engine's rotational speed in revolutions per minute (RPM). It does not show the vehicle's speed in km/h.

Is a tachometer the same as a tachograph in Belgium?

No. A tachometer displays engine speed, while a tachograph is recording equipment used in regulated road transport to record information such as vehicle speed, distance travelled and time.

Does the Belgian Road Code set traffic rules based on tachometer RPM?

No. The current Belgian Road Code does not establish general road-traffic limits based on engine RPM. Drivers must instead comply with the applicable speed limits and keep their vehicle under control.

140. Steering wheel

A steering wheel is the primary control used by a driver to change the direction of a vehicle. Turning the steering wheel operates the steering system, which changes the angle of the steered wheels and directs the vehicle along the intended path.

The driver should use the steering wheel smoothly and remain in full control of the vehicle. Modern steering systems may include power assistance, electronic controls and buttons for functions such as audio, cruise control or driver information.

Must a driver keep control of the steering in Belgium?

Yes. Every driver must remain capable of carrying out all necessary driving movements and must continuously keep the vehicle under control.

Does Belgian law prescribe a specific hand position on the steering wheel?

No general fixed hand position is prescribed in the current Belgian Road Code. The driver must nevertheless remain able to steer safely and maintain full control of the vehicle.

Can you hold a mobile phone while steering in Belgium?

No. Unless the vehicle is stationary or parked, a driver may not use, hold or manipulate a mobile electronic device with a screen unless it is secured in a holder intended for that purpose.

141. Power steering

Power steering is a steering system that assists the driver in turning the vehicle's wheels, reducing the physical effort required at the steering wheel. The assistance may be provided hydraulically, electrically or by a combination of systems.

Power steering makes vehicles easier to manoeuvre, particularly at low speeds and while parking. The amount of assistance may vary with vehicle speed so that steering remains stable and responsive during faster driving.

Is power steering mandatory on every car in Belgium?

No general rule requires every car to have power steering. The vehicle's steering system must, however, comply with the applicable technical and vehicle-approval requirements.

Must power steering be in good condition in Belgium?

Yes. The steering system is safety-critical equipment and must function correctly. Steering and steering assistance can be checked as part of vehicle technical and safety inspections.

What should you do if the power steering fails while driving in Belgium?

Keep control of the vehicle, reduce speed and stop safely when possible. Steering assistance failure can make the steering much heavier, so the vehicle should be inspected or repaired before normal driving continues.

142. Visual scanning

Visual scanning is the driving technique of continuously observing the road ahead, mirrors, side areas and surrounding traffic to identify hazards and changing traffic situations as early as possible. Effective scanning means moving attention regularly between different parts of the traffic environment rather than concentrating on a single point.

Drivers should look well ahead, check mirrors regularly and observe relevant side areas and blind spots, particularly before changing speed, direction or road position.

Is scanning specifically defined in the Belgian Road Code?

No. Scanning is a driving-observation technique rather than a separately defined legal concept, but effective observation supports the driver's obligations to remain in control and react safely to traffic conditions.

Must Belgian drivers be able to observe traffic behind them?

Yes. Rear-view mirrors must be adjusted so that the driver can observe traffic behind and to the left, including a vehicle that has started overtaking on the left.

Why must Belgian drivers scan the road ahead?

Drivers must adapt their speed to factors including other road users, traffic density, visibility and road conditions and must always be able to stop for a foreseeable obstacle.

143. Mirror

A mirror is a device fitted to a vehicle that allows the driver to observe traffic behind and beside the vehicle without turning away from the road ahead for an extended period. Vehicles commonly use an interior rear-view mirror and one or more exterior side mirrors.

Mirrors help drivers monitor surrounding traffic before changing direction, changing lane, overtaking, merging or slowing down. Because mirrors cannot show every area around a vehicle, drivers should also check their blind spots by direct observation where necessary before manoeuvring.

How must you adjust your mirrors in Belgium?

The driver must adjust the rear-view mirrors so that, from the normal driving position, they can observe traffic behind and to the left and in particular detect a vehicle that has started overtaking on the left.

Should you adjust your mirrors before starting to drive?

Yes. The mirrors should be correctly positioned for the driver's seating position before driving so that the required view of surrounding traffic is available.

Do Belgian cars need rear-view mirrors?

Yes. Cars must be equipped with the rear-view mirrors or approved indirect-vision equipment required by the applicable Belgian and European vehicle-approval rules.

Does an ordinary Belgian passenger car have an interior mirror?

Passenger vehicles are normally equipped with an interior rear-view mirror together with exterior rear-view mirrors according to their applicable technical approval requirements. Where rearward vision through the vehicle is impossible, approved exterior or indirect-vision arrangements provide the necessary view.

Can you drive with a broken mirror in Belgium?

A vehicle must continue to satisfy the applicable technical and visibility requirements. A required mirror that is missing, insecure or incapable of providing the necessary rearward view should therefore be repaired or replaced.

Do mirrors replace checking the blind spot?

No. Mirrors should be used together with direct observation where necessary. Before changing lane or moving sideways, the driver must make sure that the manoeuvre can be performed without endangering other road users.

Should you check your mirrors before overtaking in Belgium?

Yes. Before moving left to overtake, you must ensure that another driver behind has not already begun overtaking you and that the manoeuvre can be performed safely.

Should you check your mirrors before changing lane?

Yes. A lane change is a manoeuvre and must not endanger other road users. Check the mirrors and any relevant blind spot before moving into another lane.

Should you check for cyclists before opening a car door?

Yes. Before opening a door, use the mirrors and direct observation to check for cyclists, moped riders, motorcyclists and other road users approaching alongside the vehicle.

Do motorcycles need rear-view mirrors in Belgium?

Yes. Belgian technical regulations require motorcycles to be equipped with approved rear-view mirrors according to the vehicle's type and approval requirements.

How must a motorcyclist's mirrors be positioned in Belgium?

As with other drivers, the mirrors must be adjusted so the rider can observe traffic behind and to the left, including another vehicle that has begun overtaking.

Can extra mirrors be fitted when towing a caravan in Belgium?

Yes. Special removable rear-view mirrors may be fitted to the towing vehicle in addition to its normal approved mirrors when towing a caravan-type trailer, allowing the driver to maintain an adequate view behind the combination.

144. Fuel

Fuel is a source of energy used to power a vehicle's engine. Common vehicle fuels include petrol, diesel, LPG, CNG and alternative fuels. Electric vehicles use electricity rather than conventional liquid or gaseous fuel.

Drivers should always use a fuel that is compatible with their vehicle. Using the wrong fuel can damage the engine or fuel system, while economical driving and proper vehicle maintenance can reduce fuel consumption.

Fuel
How are fuels labelled at Belgian filling stations?

Belgium uses standardised European fuel labels. Petrol is identified with labels such as E5 or E10, while diesel uses labels such as B7. These labels help drivers check whether a fuel is suitable for their vehicle.

What do E5 and E10 mean in Belgium?

E5 and E10 are petrol labels indicating the permitted proportion of ethanol or other equivalent renewable components in the fuel. Drivers should check which petrol their vehicle is approved to use.

Which conventional fuels are widely available in Belgium?

Common fuels include 95 RON E10 petrol, 98 RON E5 petrol and diesel B7. LPG and other alternative fuels are also available at suitable filling stations.

145. Fuel gauge

A fuel gauge is an instrument on a vehicle's dashboard that indicates approximately how much fuel remains in the fuel tank. It usually displays a scale from empty to full and may also include a low-fuel warning light.

The reading is an estimate and can change slightly when the vehicle is on a slope, accelerating, braking or cornering. Drivers should refuel before the tank becomes completely empty.

What should you do when the low-fuel warning light appears in Belgium?

You should look for a suitable filling station and refuel as soon as reasonably possible. The remaining driving range varies between vehicles and should not be treated as a guaranteed distance.

Can you rely entirely on the fuel gauge when planning a journey?

No. The gauge only provides an approximate fuel level. For longer journeys, drivers should consider the expected distance, available filling stations and the vehicle's fuel consumption.

Why can the fuel-gauge reading change while driving?

Fuel moves inside the tank as the vehicle accelerates, brakes, corners or travels on a slope. The gauge system normally compensates for this, but temporary changes in the displayed level can still occur.

146. Petrol

Petrol, also called gasoline, is a liquid fuel commonly used in spark-ignition engines. It is produced mainly from petroleum and may contain renewable components such as ethanol.

Different grades of petrol are identified by their octane rating and ethanol content. Drivers should always use a fuel that meets the specifications recommended by the vehicle manufacturer.

Petrol
What is petrol called in Belgium?

Petrol is commonly called petrol in English and benzine or essence in Belgium's Dutch- and French-speaking contexts. At filling stations, petrol grades are identified by their octane rating and standardised fuel labels.

What petrol grades are commonly available in Belgium?

Common petrol grades include 95 RON E10 and 98 RON E5. Drivers should choose a grade that is approved for their vehicle.

Can every petrol vehicle in Belgium use E10?

No. Most modern petrol vehicles are compatible with E10, but some older vehicles may not be. Drivers should check the vehicle manufacturer's information before using E10 if compatibility is uncertain.

147. Diesel

Diesel is a liquid fuel used in compression-ignition engines. Unlike petrol engines, diesel engines ignite the fuel through the heat produced by compressing air rather than by using spark plugs.

Diesel fuels can contain renewable components such as biodiesel. Drivers should always use a diesel grade that is approved by the vehicle manufacturer, as using an incompatible fuel can damage the engine or fuel system.

Diesel

Which diesel fuel is commonly sold in Belgium?

Diesel B7 is the standard diesel commonly available for road vehicles in Belgium. It can contain up to 7% biocomponents and complies with the European diesel standard for road vehicles.

Are other types of diesel available in Belgium?

Yes. Other diesel fuels such as B10 and XTL can also be marketed in Belgium. Drivers should check that their vehicle is compatible before using an alternative diesel grade.

How is diesel identified at Belgian filling stations?

Diesel fuels use standardised European square fuel labels containing designations such as B7 or B10. These labels help drivers identify the correct fuel for their vehicle.

148. Diesel exhaust fluid

Diesel exhaust fluid (DEF) is a liquid used by many modern diesel vehicles with selective catalytic reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions. In Europe it is commonly known by the trade name AdBlue.

DEF is not diesel fuel and is stored in a separate tank. It is a solution containing high-purity urea and water that is injected into the exhaust system, where it helps convert nitrogen oxides into less harmful substances.

What is diesel exhaust fluid called in Belgium?

Diesel exhaust fluid is commonly known as AdBlue in Belgium. It is used by diesel vehicles equipped with selective catalytic reduction systems to reduce nitrogen oxide emissions.

Can AdBlue be added to the diesel tank?

No. AdBlue and diesel must be kept completely separate. AdBlue has its own tank and filler opening, and putting either liquid into the wrong tank can cause serious vehicle problems.

Should you refill AdBlue when the dashboard warning appears?

Yes. The warning indicates that the AdBlue level is becoming low. Drivers should refill it with a suitable product according to the vehicle manufacturer's instructions rather than waiting until the tank is empty.

149. Car insurance

Car insurance is financial protection for risks associated with owning or using a motor vehicle. Depending on the policy, it can cover liability for injury or damage caused to other people, as well as damage to, theft of or other losses involving the insured vehicle.

The minimum insurance required by law varies between countries. Drivers can often purchase additional cover beyond the compulsory minimum, such as collision, comprehensive, theft, fire or roadside-assistance protection.

Is car insurance compulsory in Belgium?

Yes. Vehicles subject to the Belgian insurance obligation must have civil liability motor insurance when they are used on public roads or other areas covered by the legal requirement.

What does compulsory Belgian car insurance cover?

The compulsory civil liability insurance covers the insured person's legal liability for injury and property damage caused to third parties by the insured vehicle, subject to the applicable insurance rules and policy conditions.

Are additional forms of car insurance compulsory in Belgium?

No. Civil liability motor insurance is the compulsory element. Additional protection, such as cover for theft, fire, glass damage, accidental damage or other risks, can be purchased voluntarily according to the driver's needs and the insurer's policy conditions.

150. First aid kit

A first aid kit is a collection of medical supplies intended for providing immediate basic care after an injury or accident. A vehicle first aid kit commonly contains items such as sterile dressings, bandages, adhesive plasters and other basic wound-care materials.

Some countries require certain vehicles to carry a first aid kit, while in others it is only recommended. The kit should be stored where it can be reached when needed, and its contents should be checked regularly so that required items remain complete and usable.

Is a first aid kit compulsory in a car in Belgium?

Yes. Cars in Belgium must carry the required first-aid equipment. For an ordinary passenger car, this normally takes the form of a first-aid case containing the items prescribed by the technical vehicle regulations.

What must a Belgian car first aid kit contain?

The prescribed basic kit includes sterile dressings, triangular gauze, bandages, antiseptic adhesive plasters and safety pins or equivalent fasteners. It must also contain information about its contents and first-aid instructions.

Do buses and coaches need a larger first aid kit in Belgium?

Yes. Buses, coaches and certain vehicles used for passenger transport must carry a larger universal first-aid chest. Vehicles in this category with a maximum authorised mass above 5000 kg must carry two such first-aid chests.
