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.
