Accident caused after alcohol: consequences in Belgium (2026)
You caused a traffic accident after drinking alcohol. In Belgium, this typically leads to two tracks of consequences:
- Criminal: prosecution for an alcohol-related offence (alcohol intoxication and/or drunkenness) and, often, for the traffic offence connected to how the accident happened.
- Civil / insurance: victims must be compensated, but in some cases your insurer may pursue recourse (recovery) or refuse cover (especially under comprehensive/“omnium” policies).
This article explains what you can generally expect and why causation is often the key point of dispute.
Two issues: alcohol and the accident
When you cause an accident and alcohol is established, you may be prosecuted for:
- Alcohol intoxication (measured via breath analysis / blood test)
- Drunkenness (a condition assessed through external signs)
- And, in addition: the traffic offence that led to the accident
In practice, this often results in a summons before the Police Court.

Alcohol intoxication vs drunkenness: a crucial legal distinction
Alcohol intoxication (objective)
Alcohol intoxication is based on a measured level. In Belgium, it becomes punishable from 0.22 mg/l in exhaled alveolar air (UAL), which corresponds to 0.5 ‰.
Drunkenness (condition)
Drunkenness is different: it refers to a state where you have lost the consistent control of your actions. It is typically inferred from external signs recorded in the police report (behaviour, coordination, speech, etc.).
Key takeaways:
- Drunkenness often involves intoxication, but not necessarily.
- You can be intoxicated without drunkenness being proven.
Practical thresholds (mg/l and ‰)
Many people think in “promille”, while roadside enforcement often uses mg/l UAL. This overview is practical (indicative).
Note: the concrete response depends on the district, your prior record, the circumstances of the crash, and prosecution policy.
Criminal consequences: what can you face?
If you cause an accident and alcohol is established, the Police Court judge may (depending on the facts) impose:
- Fine
- Driving ban
- Rehabilitation exams/assessments (especially in more serious or repeat cases)
- Alcohol interlock in certain cases
Internal deep-dives (Dutch pages):
Immediate licence withdrawal: often stricter in practice
Before your court hearing, your driving licence may be withdrawn immediately as a safety measure.
What matters:
- There are national guidelines that have lowered certain thresholds over recent years.
- Some prosecution districts apply stricter practice depending on local policy.

Civil and insurance: who pays the damage?
1) Damage to third parties: mandatory liability insurance compensates victims
Belgian motor third-party liability insurance (BA/RC) is mandatory. Broadly:
- Victims (third parties) are compensated, even if you drank.
But that does not always end the matter.
Insurer recourse: when can the insurer try to recover money?
In certain circumstances, the liability insurer may pursue recourse (recovering part of what it paid).
In practice, two pillars often come back:
- Drunkenness (not merely intoxication)
- Causation between drunkenness and the accident
2) Your own damage: comprehensive (“omnium”) cover is contractual (often stricter)
Comprehensive insurance is not mandatory. Policy terms often allow the insurer to:
- refuse cover, or
- recover paid amounts
in cases of intoxication and/or drunkenness (often tied to causation, and sometimes with stricter contractual wording).
Causation: why this is often the core dispute
In insurance disputes and proceedings, one question is frequently decisive:
- Was alcohol merely “present”, or did it (contribute to) causing the accident?
Insurers and courts typically look at:
- The mechanics of the crash (priority rules, speed, manoeuvres)
- Objective elements (braking marks, damage pattern, road situation)
- Your conduct before/during/after
- The criminal file (police report, witnesses, findings)
One combined sentence is not automatically proof of causation
Sometimes one sentence covers (1) the alcohol offence and (2) the accident-related offence. Insurers may argue this proves alcohol caused the crash.
That is not automatic: a combined sentence can have procedural reasons, without an explicit legal finding on causation. It remains file-specific.
Frequently asked questions
Will I always be summoned to court?
Not always, but where an accident is combined with alcohol findings, criminal follow-up is very common, especially with:
- injuries
- clear fault
- higher levels
- prior offences
- related offences (e.g., hit-and-run)
Will my insurance still pay if I drank?
- For third parties: usually yes (mandatory liability), with possible recourse afterwards.
- For your own damage: it depends on your omnium terms.
Do I have to stay at the scene?
Yes. Leaving when you knew (or should have known) you were the cause or occasion of an accident can lead to prosecution for hit-and-run.

Practical steps after an accident if you drank
- Secure the scene and call emergency services if there is danger or injury
- Take photos and note details (positions, signs, damage)
- Cooperate with findings, but be cautious with spontaneous admissions about fault or cause
- Contact your legal expenses insurance quickly if you have it
- Seek advice when there are injuries, fault disputes, or a recourse risk
