252. Alcoolémie
L’alcoolémie (BAC), plus précisément la concentration d’alcool dans le sang, indique la quantité d’alcool présente dans le sang d’une personne. Elle est couramment exprimée en pourcentage, en grammes par litre ou en pour mille (‰). L’alcool peut altérer le jugement, le temps de réaction, la coordination et la vision avant même que la limite légale soit atteinte. Les limites varient selon les pays et peuvent être plus faibles pour les conducteurs professionnels, novices ou jeunes.
What is the legal blood alcohol limit for ordinary drivers in Belgium?
For most drivers, the legal threshold is 0.5‰ alcohol in the blood. A driver is punishable from this concentration, corresponding to 0.22 mg/l of alcohol in exhaled alveolar air.
What does 0.5‰ mean in Belgium?
A blood alcohol concentration of 0.5‰ means 0.5 grams of alcohol per litre of blood.
Is the Belgian BAC limit lower for young or inexperienced drivers?
No. The standard 0.5‰ BAC limit also applies to young and inexperienced drivers in Belgium.
Is the BAC limit lower for professional drivers in Belgium?
Yes. Applicable professional drivers are punishable from 0.2‰ alcohol in the blood, corresponding to 0.09 mg/l in exhaled alveolar air. The stricter limit also applies when driving certain heavy vehicle categories outside professional activities.
How is alcohol concentration measured during a Belgian roadside control?
Police normally use breath testing and breath analysis. A blood test can be used in circumstances provided by law, including certain cases where breath analysis cannot be performed or as a counter-analysis.
Can you request a blood test after a breath analysis in Belgium?
Yes. When a breath analysis measures at least 0.35 mg/l, the person must be informed of the right to request a blood test as a counter-analysis.
Does being below 0.5‰ mean you are safe to drive in Belgium?
No. Alcohol can affect driving before the legal limit is reached. The safest approach is not to drink alcohol when you plan to drive.
