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 most drivers, the maximum permitted concentration is 0.21 mg/l of alcohol in exhaled breath. A driver becomes punishable from 0.22 mg/l, corresponding to 0.5‰ in the blood.

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.

Is there a lower alcohol limit for professional drivers in Belgium?

Yes. Professional drivers performing applicable passenger or goods transport are punishable from 0.09 mg/l in exhaled breath or 0.2‰ in the blood. The stricter limit also applies when driving certain heavy vehicle categories even outside professional work.

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.

Can driving under the influence of alcohol lead to a driving ban in Belgium?

Yes. Depending on the alcohol concentration and circumstances, consequences can include an immediate driving prohibition or licence withdrawal, fines, court proceedings and disqualification from driving.

Can a Belgian court require an alcohol interlock?

Yes. A court can impose an alcohol interlock for certain alcohol offences, repeat offences or high alcohol concentrations. In some serious cases, the court is required to impose one unless the law allows a specifically reasoned exception.

What are the immediate fines for alcohol offences in Belgium in 2026?

Since 1 July 2026, immediate collections for alcohol offences handled on the spot start at €116 for applicable professional drivers between 0.09 and 0.22 mg/l of exhaled breath, and at €197 for ordinary offences between 0.22 and 0.35 mg/l. Higher concentrations result in higher penalties and may lead to court proceedings.

Is it safest to drive after drinking if you remain below the Belgian legal limit?

No. Alcohol can impair driving before the legal limit is reached. The safest approach is not to drink alcohol when you plan to drive.
