226. Doors
Doors provide access to the vehicle and help protect occupants while the vehicle is moving. They must open and close correctly, remain securely closed during driving and have functioning hinges, catches and locking mechanisms. Damaged or loose doors can create a serious safety risk, especially if they can open unexpectedly or cannot be closed properly.

Are vehicle doors checked during the technical inspection in Belgium?
Yes. Vehicle doors and their hinges, catches and supporting structure can be checked during the technical inspection to ensure they are secure and operate correctly.
Can a door that does not open or close correctly fail the Belgian technical inspection?
Yes. A door that does not open or close correctly is considered a defect during technical inspection and may lead to rejection depending on its severity.
What if a vehicle door can open unexpectedly?
A door that can open unexpectedly or cannot remain securely closed is a serious safety defect. The severity can depend on the type of door and the risk it creates.
227. Glovebox
A glovebox, also called a glove compartment, is a storage compartment built into the dashboard in front of the passenger seat. It is commonly used to keep vehicle documents, the owner’s manual and other small items within easy reach. The glovebox should be kept closed while driving so that it does not obstruct passengers or allow loose objects to fall into the vehicle. Avoid storing valuables or items that can be damaged by the high temperatures that may develop inside a parked car.
Wikimedia.org • Q4RadioGuy • CC BY
Do vehicle documents have to be kept in the glovebox in Belgium?
No. Belgian rules require certain vehicle and driver documents to be available while driving, but they do not have to be stored specifically in the glovebox.
Can you keep copies of the vehicle documents in the glovebox in Belgium?
Copies do not normally replace the required originals during a police check. The Federal Police advises drivers to be able to present the original vehicle documents.
228. Visibility
Visibility is the ability of a driver to see the road, other road users and potential hazards clearly, while also making the vehicle visible to others. Visibility can be reduced by darkness, fog, rain, snow, dirty or misted windows, glare and objects that obstruct the driver’s view. Drivers should keep windows, mirrors and lights clean, remove anything that blocks their field of vision and use the appropriate vehicle lights when visibility is reduced.
Wikimedia.org • Rick Doble • CC BY-SA
Must a driver have a clear view of the road in Belgium?
Yes. Belgian vehicle requirements provide that the driver must have a sufficient view ahead and to the sides. Windscreens, windows and other equipment should therefore not unnecessarily obstruct the driver’s field of vision.
Can a vehicle's load obstruct the driver's visibility in Belgium?
No. A vehicle and its load must be arranged so that the load does not obstruct the driver's visibility, create danger or hide required lights, reflectors or the registration number.
When must vehicle lights be used because of poor visibility in Belgium?
Under the current Belgian traffic rules, the prescribed vehicle lights must be used between nightfall and dawn and whenever it is no longer possible to see clearly for approximately 200 metres.
229. Rain
Rain can reduce visibility, tyre grip and vehicle control while increasing stopping distances. Water on the road can also cause aquaplaning, where the tyres lose contact with the road surface. Drivers should reduce speed, increase their following distance, avoid sudden steering or braking and use the appropriate lights when visibility is reduced. Extra care is needed during heavy rain and when water collects in wheel tracks or on poorly drained roads.
Do you have to reduce your speed in rain in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to the weather conditions, visibility, road condition and traffic situation. Drivers must also maintain a sufficient safety distance and be able to stop before a foreseeable obstacle.
When must rear fog lights be used in heavy rain in Belgium?
Under the current Belgian traffic rules, rear fog lights must be used in heavy rain when the vehicle is equipped with them. They may not be used in other circumstances unless another permitted condition, such as sufficiently dense fog or snowfall, applies.
May front fog lights be used in heavy rain in Belgium?
Yes. Under the current rules, front fog lights may be used during heavy rain. They may replace the dipped or main-beam headlights or be used together with them.
230. Fog
Fog can greatly reduce visibility and make it difficult to judge speed, distance and the position of other road users. Drivers should reduce speed, increase their following distance and use the appropriate lights without dazzling others. Avoid relying only on the vehicle ahead as a guide, and be prepared for sudden changes in visibility. When fog is very dense, stopping in a safe place may be the best option.
Wikimedia.org • Michiel1972 • CC BY-SA
Do you have to reduce your speed in fog in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to visibility, weather, road conditions and traffic. The posted speed limit may therefore be too fast when visibility is reduced by fog.
When must rear fog lights be used in Belgium?
Under the current Belgian rules, rear fog lights must be used when fog reduces visibility to less than approximately 100 metres. They may not be used in other circumstances unless another permitted condition applies.
May front fog lights be used in fog in Belgium?
Yes. Under the current rules, front fog lights may be used in fog. They may replace the dipped or main-beam headlights or be used together with them.
231. Hail
Hail can reduce visibility, make the road slippery and create sudden hazardous driving conditions. Hailstones may accumulate on the road and reduce tyre grip in a similar way to ice or loose material, while larger hailstones can also damage windscreens and vehicle bodywork. Drivers should reduce speed, increase their following distance, avoid sudden steering or braking and, when conditions become severe, consider stopping at a safe place until the hailstorm passes.
Do you have to reduce your speed during hail in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to the weather, visibility, road condition and traffic situation. The posted speed limit may therefore be too fast during a hailstorm.
What should you do if hail accumulates on the road in Belgium?
Reduce speed, increase your following distance and avoid sudden steering or braking. Accumulated hail can create a slippery road surface with greatly reduced grip.
Can hail damage affect the safety of a vehicle in Belgium?
Yes. Hail can damage the windscreen, windows, mirrors or lights. If damage affects the driver’s visibility or the safe operation of the vehicle, it should be repaired before continuing to drive when necessary.
232. Sunlight
Sunlight can reduce visibility when the sun is low in the sky or when bright light reflects from wet roads, snow, buildings or other vehicles. Sun glare can make traffic lights, signs, pedestrians and other road users difficult to see. Drivers should reduce speed when necessary, keep the windscreen clean, use the sun visor or suitable sunglasses and leave extra space to react to hazards that may be temporarily hidden by glare.
Wikimedia.org • Frank Contreras Cardenas • CC BY-SA
Do you have to reduce your speed when sunlight reduces visibility in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to visibility, weather, road conditions and traffic. Strong sun glare can therefore require a lower speed even when the posted speed limit is higher.
Must the driver have a clear view of the road in Belgium?
Yes. Belgian vehicle requirements provide that the driver must have a sufficient view ahead and to the sides. Objects or equipment should therefore not significantly obstruct the driver’s field of vision.
Can a dirty or damaged windscreen make sun glare more dangerous in Belgium?
Yes. Dirt, scratches, cracks or discoloration can scatter sunlight and reduce visibility. Keeping the windscreen clean and in good condition is particularly important when driving toward a low sun.
233. Sunglasses
Sunglasses can reduce glare and improve visual comfort when driving in bright sunlight, especially when the sun is low or reflects from wet roads, snow or other surfaces. Drivers should choose lenses that allow traffic lights, signs and other road users to remain clearly visible. Very dark lenses can reduce visibility in tunnels, at night or in changing light conditions, so sunglasses should be removed when they make it harder to see the road safely.
Wikimedia.org • Vancouver 125 • CC BY
Can you wear sunglasses while driving in Belgium?
Yes. There is no general prohibition on wearing sunglasses while driving, and the Belgian Federal Police recommends them as a useful way to reduce glare from a low sun. They should not make it harder to see the road safely.
🔗 politie.be • Federal Police, sunglasses and low-sun driving
🔗 politie.be • Ghent Police, low-sun safety
🔗 codex.vlaanderen.be • Vlaamse Codex, Road Code, applicable article versions through 31 May 2027
Do sunglasses replace the need to reduce speed when the sun affects visibility in Belgium?
No. Even when wearing sunglasses, drivers must adapt their speed to the available visibility and driving conditions. Sunglasses can reduce glare but cannot eliminate every visibility problem.
What if your Belgian driving licence requires you to wear glasses?
Belgian driving licences can contain medical restriction codes for vision correction, including code 01.01 for glasses and 01.06 for glasses or contact lenses. Drivers must respect any vision-correction requirement shown on their licence.
234. Salt
Salt is commonly used for deicing and anti-icing roads in winter. It lowers the freezing point of water, helping to prevent ice from forming or to melt existing snow and ice. Road authorities may spread dry salt, wet salt or brine before or during freezing conditions. Salt improves road safety, but drivers should still reduce speed and adapt to slippery conditions because treated roads can remain hazardous, especially during heavy snowfall, freezing rain or very low temperatures.
Is salt used to treat roads in Belgium?
Yes. Belgian road authorities use salt, wet salt and brine to help prevent or remove snow and ice during winter conditions.
Are Belgian roads salted before ice forms?
Yes. Road authorities can carry out preventive salting before frost, ice, snow or freezing rain develops. This is known as anti-icing and can reduce the risk of slippery roads.
Who is responsible for salting roads in Belgium?
Responsibility follows the road manager. In Flanders, the regional road agency treats motorways and regional roads, while municipalities are responsible for their municipal roads. Check the relevant authority’s winter-service information for your location.
235. Air conditioning
Air conditioning helps control the temperature and humidity inside a vehicle and can improve comfort and visibility. In hot weather it cools the passenger compartment, while in damp conditions it can help remove moisture from the air and clear mist from the windows more quickly. Drivers should use the system in a way that keeps the interior comfortable without creating large temperature differences, and the system should be maintained so that it continues to work effectively.
Wikimedia.org • Mattes • CC0
Is air conditioning mandatory in cars in Belgium?
No. Air conditioning itself is not generally mandatory equipment for passenger cars in Belgium. However, the vehicle must still provide adequate visibility and comply with applicable technical requirements.
Is the demisting system important in Belgium?
Yes. A functioning demisting and defrosting system is important for maintaining clear visibility through the windscreen and forms part of the applicable vehicle safety requirements.
Is the demisting system checked during the Belgian technical inspection?
Yes. European roadworthiness rules used as the basis for Belgian technical inspection include checks of the windscreen demisting system. A system that does not operate correctly can be recorded as a defect.
236. Hydroplaning
Hydroplaning, also called aquaplaning, occurs when a layer of water builds up between a vehicle’s tyres and the road surface, causing the tyres to lose contact with the road. Steering, braking and acceleration can then become much less effective. The risk increases with speed, standing water and worn tyres. Drivers should reduce speed in heavy rain, avoid sudden steering or braking and make sure their tyres are in good condition with sufficient tread depth.
Do you have to reduce your speed when there is a risk of hydroplaning in Belgium?
Yes. Belgian traffic rules require drivers to adapt their driving to the weather, visibility and condition of the road. Heavy rain or standing water can therefore require a lower speed than the posted maximum.
Is there a special Belgian speed limit for hydroplaning?
No. Belgium does not have a general speed limit specifically for hydroplaning. Drivers must instead choose a speed that is safe for the actual road and weather conditions.
What should you do if your car starts hydroplaning in Belgium?
Ease off the accelerator, avoid sudden braking or steering and allow the tyres to regain grip. Belgian rules require drivers to adapt their behaviour to the road and weather conditions.
237. Distraction
Distraction is anything that takes a driver’s attention away from safely controlling the vehicle and observing the road. Common distractions include mobile phones, navigation systems, passengers, eating, adjusting controls or looking away from traffic. Distraction can be visual, manual or mental and may significantly increase reaction time. Drivers should keep their attention on the road, prepare navigation and other settings before moving and avoid activities that interfere with safe driving.
Wikimedia.org • Melissa Wenger • CC0
Can you use a mobile phone while driving in Belgium?
Not while holding or manipulating it. Unless the vehicle is stopped or parked, a driver may not use, hold or manipulate a mobile electronic device with a screen unless it is fixed to the vehicle in a holder intended for that purpose.
Does the Belgian phone rule apply only to smartphones?
No. The rule applies broadly to mobile electronic devices with a screen, not only phones. This can include devices such as tablets and smartwatches.
Can you use a phone mounted in a holder in Belgium?
The specific prohibition on using a mobile electronic device does not apply when the device is fixed to the vehicle in a holder intended for that purpose. The driver must nevertheless remain in control of the vehicle and avoid unsafe distraction.
238. Emotions
Emotions can influence attention, judgement and driving behaviour. Anger, stress, fear, sadness or excitement may cause a driver to become distracted, impatient or more likely to take risks. Strong emotions can also affect concentration and reaction time. Drivers should recognise when their emotional state is interfering with safe driving and, if necessary, slow down, take a break or stop in a safe place until they feel able to continue calmly and attentively.
Wikimedia.org • Raysonho • CC0
Are there specific Belgian traffic rules about emotions while driving?
No. Belgian traffic rules do not create a separate offence specifically for being angry, stressed or upset while driving. However, every driver must be fit to drive, remain able to perform the required manoeuvres and keep control of the vehicle.
Can strong emotions make your driving unlawful in Belgium?
Potentially. If emotions lead to behaviour such as speeding, dangerous manoeuvres, failing to keep control or ignoring traffic rules, the driver can be responsible for those violations.
What should you do if anger or stress affects your driving in Belgium?
If you can no longer concentrate or control your driving safely, it is better to stop at a safe and permitted place and continue only when you are able to drive calmly and attentively.
239. Road rage
Road rage is aggressive, hostile or intimidating behaviour by a road user toward others in traffic. It can include excessive honking, tailgating, shouting, threatening gestures, blocking another vehicle or making deliberately aggressive manoeuvres. Anger can reduce judgement and increase risk-taking, turning a minor traffic conflict into a dangerous situation. Drivers should avoid confrontation, remain calm, keep a safe distance and never retaliate against aggressive behaviour.
Wikimedia.org • DaleHulm • CC BY-SA
Is road rage a separate traffic offence in Belgium?
Road rage is not a separate named traffic offence under the Belgian Road Code. However, specific behaviour caused by road rage can violate traffic rules or other laws.
Can aggressive driving violate Belgian traffic rules?
Yes. Belgian road users must behave so that they do not cause danger or obstruction to other road users. Aggressive manoeuvres that create danger can therefore breach the traffic rules.
Does a driver have to remain in control of the vehicle in Belgium?
Yes. Every driver must be capable of performing the necessary driving manoeuvres and remain in control of the vehicle at all times.
240. Health
Health can affect a person’s ability to drive safely. Illness, injury, poor vision, reduced mobility, fatigue, certain medical conditions and some medicines can interfere with concentration, reaction time, judgement or vehicle control. Drivers should recognise when their physical or mental condition may make driving unsafe and should seek medical advice when necessary. In some countries, specific health conditions must be reported and may require a medical examination or restrictions on the driving licence.
Wikimedia.org • Shixart1985 • CC BY
Do you have to be medically fit to drive in Belgium?
Yes. Belgian law requires drivers to meet minimum physical and mental fitness standards. Driving fitness means that no medical condition, disability, injury or medication significantly increases the risk of an accident.
Who is responsible for checking their medical fitness to drive in Belgium?
The driver is responsible for ensuring that they continue to meet the medical fitness standards. If a health problem may affect safe driving, medical assessment may be required.
What should you do if a health condition may affect your driving in Belgium?
You should consult your doctor. Depending on the condition, the doctor may issue a driving-fitness certificate or refer you to a specialised driving-fitness centre for further assessment.
241. Epilepsy
Epilepsy is a neurological condition that can cause recurrent seizures, which may involve changes in awareness, movement, sensation or consciousness. Because a seizure can temporarily prevent a person from controlling a vehicle safely, epilepsy can affect driving fitness and driving-licence requirements. The rules vary between countries and usually depend on factors such as the type of seizure, how long the person has been seizure-free, treatment and medical assessment. Anyone who experiences a seizure should follow the applicable driving rules and seek medical advice before driving again.
Wikimedia.org • Henry Vandyke Carter • CC0
Can you drive with epilepsy in Belgium?
A person with epilepsy is initially considered not medically fit to drive, but may later be declared fit if the legal medical criteria are met, including the required seizure-free period and a favourable neurological assessment.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
How long must someone with epilepsy be seizure-free to drive a car in Belgium?
For a group 1 licence, which includes ordinary cars and motorcycles, a person with epilepsy can generally be declared fit after being seizure-free for at least one year, provided the other medical conditions are satisfied.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
What are the rules after a single epileptic seizure in Belgium?
For group 1 drivers, a person who has experienced a single epileptic seizure may generally be declared fit after at least six seizure-free months. In certain circumstances, this can be reduced to three months when neurological tests meet the required conditions.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
242. Night blindness
Night blindness, also called nyctalopia, is reduced ability to see in darkness or low-light conditions. It can make it difficult to recognise pedestrians, cyclists, road markings, bends or obstacles at night and during twilight. Night blindness can have different causes, including certain eye conditions, vitamin deficiencies or problems with the retina. Drivers who have difficulty seeing in low light should avoid driving in conditions where their vision is inadequate and seek professional eye care.
Wikimedia.org • Alex Proimos • CC BY
Are there minimum vision requirements for driving at night in Belgium?
Yes. Belgian driving-fitness standards consider several aspects of vision, including visual acuity, visual field, twilight vision, sensitivity to light and contrast and other visual functions needed for safe driving.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
What should you do if you have difficulty seeing at night in Belgium?
If your vision may no longer meet the driving-fitness standards, you should have it assessed by an ophthalmologist. The ophthalmologist can determine whether you remain medically fit to drive or whether further assessment is needed.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
Can night blindness affect your Belgian driving licence?
Yes. If reduced night or twilight vision affects driving fitness, a driver may be declared fit with conditions or restrictions, temporarily unfit or unfit to drive, depending on the medical assessment.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
243. Visual impairment
Visual impairment is a reduction in vision that can affect a person’s ability to see clearly, judge distances, detect movement or recognise hazards. It can involve reduced visual acuity, a restricted field of vision, poor contrast sensitivity, double vision or difficulty seeing in low light. Because safe driving depends heavily on vision, drivers must meet the minimum eyesight standards required in their country and use glasses, contact lenses or other approved visual aids when necessary.
Wikimedia.org • Anonymous9000 • CC BY
Are there minimum eyesight requirements for driving in Belgium?
Yes. Belgian driving-fitness rules assess visual acuity, field of vision, twilight vision, contrast and light sensitivity, double vision and other visual functions that are important for safe driving.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
What is the minimum visual acuity for an ordinary driving licence in Belgium?
For a group 1 licence, including ordinary cars and motorcycles, the driver must generally have a binocular visual acuity of at least 5/10, with optical correction if necessary.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
What should you do if your eyesight may no longer be good enough to drive in Belgium?
You should have your vision assessed by an ophthalmologist. The ophthalmologist can determine whether you remain fit to drive and may refer you to a specialised driving-fitness centre for further assessment.
🔗 wegcode.be • Belgian Driving Licence Decree, Annex6 II.3 and III — group1 seizures and vision
244. Fatigue
Fatigue reduces concentration, reaction time, judgement and the ability to stay alert while driving. It can develop after long periods behind the wheel, insufficient sleep, illness, irregular working hours or driving at times when the body normally expects rest. Warning signs include frequent yawning, heavy eyelids, difficulty keeping a steady speed or lane position and forgetting parts of the journey. Drivers should stop and rest as soon as they notice signs of tiredness and should not rely on caffeine, fresh air or loud music as substitutes for sleep.
Is it illegal to drive while extremely tired in Belgium?
Belgian traffic rules do not set a specific fatigue limit, but every driver must be fit to drive, able to perform the necessary manoeuvres and remain in control of the vehicle. Driving when fatigue prevents this can therefore conflict with the general driving requirements.
Is fatigue included in Belgian driver training and theory exams?
Yes. Belgian driving-licence rules specifically include the effects of fatigue on driver behaviour, perception, judgement and reaction among the subjects covered by the theory examination.
🔗 wegcode.be • Belgian current Driving Licence Decree Annex4 — fatigue in theory curriculum
What should you do if you become tired while driving in Belgium?
Stop at a safe and permitted place and rest before continuing. Do not continue driving if fatigue prevents you from remaining alert and in full control of the vehicle.
245. Defects
Defects are faults, damage or wear that can affect a vehicle’s safety, roadworthiness or compliance with technical requirements. Defects may involve tyres, brakes, lights, steering, suspension, windows, bodywork, electrical systems or other components. Some are minor and should be repaired as soon as possible, while serious or dangerous defects can make the vehicle unsafe to drive. Drivers should regularly check their vehicle and repair problems before they become a safety risk.
Wikimedia.org • Wikiuser100000 • CC BY-SA
How are vehicle defects classified during technical inspection in Belgium?
Belgian technical inspections distinguish between minor, serious and dangerous defects. The result determines whether the vehicle receives a green or red inspection certificate and whether reinspection is required.
What happens if only minor defects are found in Belgium?
A vehicle can receive a green inspection certificate with remarks. Some defects must be repaired as soon as possible, while others must be monitored even though no immediate reinspection is required.
What happens if serious defects are found in Belgium?
Serious defects can result in a red inspection certificate with limited validity. In Flanders, code 2 normally gives 15 days to repair the defects and present the vehicle for reinspection.
246. Traffic violation
A traffic violation is an act that breaks a traffic law or road rule, such as speeding, ignoring a traffic sign, using a prohibited device while driving or failing to give way. Violations vary in seriousness and can lead to warnings, fines, penalty points, licence suspension or other sanctions depending on the country. More serious behaviour that creates a high risk to other road users may result in heavier penalties or criminal proceedings.
How are traffic violations classified in Belgium?
Belgian traffic violations are divided into four degrees. The higher the degree, the more serious the offence and the heavier the possible penalty.
What is a first-degree traffic violation in Belgium?
A first-degree violation is generally a less serious traffic offence. Provisions of the traffic regulations that are not specifically assigned to another degree are normally treated as first-degree violations.
Are speeding offences included in the four-degree system in Belgium?
Speeding has its own fine and penalty rules based on factors such as how far the speed limit was exceeded and where the offence occurred. It is therefore treated separately from the standard four-degree classification.
247. Alcohol
Alcohol affects judgement, reaction time, coordination, concentration and vision, making it dangerous to drive even before a person feels drunk. The legal alcohol limit varies between countries and may be lower for professional, novice or young drivers. The safest choice is not to drink alcohol before driving. Drivers who have consumed alcohol should use an alternative such as a sober designated driver, public transport or a taxi.
What is the legal alcohol limit for ordinary drivers in Belgium?
For ordinary drivers, the punishable threshold is at least 0.22 mg/l of alcohol in exhaled alveolar air, or at least 0.5‰ in the blood. These are alternative legal measurement thresholds. Being below them does not establish that someone is fit to drive; the safest choice is not to drink before driving.
Is the alcohol limit lower for young or inexperienced drivers in Belgium?
No. The standard limit of 0.5‰ in the blood also applies to young and inexperienced drivers. Belgium does not currently impose a separate lower alcohol limit simply because a driver is new or young.
How can the police test drivers for alcohol in Belgium?
The police can use screening devices, breath tests and breath-analysis equipment. In certain circumstances, a blood test can also be used to determine the alcohol concentration.
248. Alcohol control
An alcohol control is a roadside check used to determine whether a driver has consumed alcohol and whether the legal alcohol limit has been exceeded. Police may use a screening device, breath test, breath analysis or, in some situations, a blood test. The exact procedure and legal limits vary between countries. Drivers must normally cooperate with authorised testing, and refusing a lawful alcohol test can itself lead to penalties.
Can the police require any driver to take an alcohol test in Belgium?
Yes. Police can require a breath test from anyone driving on a public road, anyone preparing to drive, a person accompanying a learner driver and people who may have been involved in a traffic accident.
How does an alcohol control work in Belgium?
Police may first use an alcohol-detection device or breath test. When the breath test reaches the applicable legal threshold, a more precise breath analysis is carried out to measure the alcohol concentration.
When is a breath analysis required in Belgium?
For ordinary drivers, a breath analysis is carried out when the breath test indicates at least 0.22 mg/l of alcohol in exhaled alveolar air. For drivers subject to the stricter professional limit, the threshold is 0.09 mg/l.
249. Ignition interlock device
An ignition interlock device, also called an alcohol interlock or alcolock, is a breath-testing device connected to a vehicle’s ignition system. Before the vehicle can be started, the driver must provide a breath sample below a programmed alcohol limit. The device may also require additional tests during a journey and can record information about tests, failed attempts and possible tampering. Ignition interlocks are used in some countries as a safety measure or legal requirement for drivers convicted of alcohol-related offences.
Wikimedia.org • Spielvogel • CC0
What is an alcohol interlock in Belgium?
An alcohol interlock is a breath-testing device connected to the vehicle. A driver subject to an alcohol-interlock programme can only start the vehicle after providing a breath sample below the required alcohol limit.
What alcohol limit does a Belgian alcohol interlock use?
The vehicle can only be started after a breath test showing less than 0.09 mg/l of alcohol in exhaled breath, corresponding to less than approximately 0.2‰ alcohol in the blood.
🔗 wegcode.be • Belgian Road Traffic Act61quinquies — interlock programme threshold below0.09mg/l
When can a Belgian court impose an alcohol interlock?
A court can impose an alcohol interlock for the specified offences, including the higher alcohol-concentration offence beginning at 0.8‰ in blood or 0.35 mg/l in breath, drunken driving and relevant repeat offences. At still higher concentrations and for specified repeat convictions, the law provides additional mandatory rules, subject to its stated conditions and exceptions.
250. Breath test
A breath test is a preliminary roadside test used to detect alcohol in a person’s breath and determine whether further testing is required. The person blows into a portable testing device, which compares the alcohol level with predefined thresholds. A breath test is generally used for screening rather than providing the final evidential measurement. If the result reaches the applicable limit, a more precise breath analysis or another legally recognised test may follow.
What is a breath test in Belgium?
A Belgian breath test is a preliminary alcohol test in which a person blows into an approved device that indicates the level of alcohol in the exhaled alveolar air relative to specified legal thresholds.
Does a Belgian breath test show the exact alcohol concentration?
Normally, no. The breath-test device indicates a result category based on legal thresholds rather than displaying the exact alcohol concentration used as the evidential result. The precise measurement is obtained by a breath analysis.
What results can an ordinary driver receive on a Belgian breath test?
For ordinary drivers, the device distinguishes between alcohol levels below 0.22 mg/l, from 0.22 mg/l to below 0.35 mg/l, and 0.35 mg/l or higher. These are represented by result codes such as S, A and P.
