Drinking and driving

In most cases, the standard legal maximum blood alcohol level of 0.5 mg/100 ml applies. However, in some specific circumstances, this limit may be reduced to 0.1 mg/100 ml or below.


To convert the level of alcohol on your breath (as measured by a breathalyser) to the level of alcohol in your blood (as measured by a blood test), double the breath alcohol reading. For example, if a breathalyser shows your alcohol level as 0.25 mg/l, this means your blood alcohol level will be 0.5 mg/100 ml.

The table below lists each individual licence category, and the probationary period in which the blood alcohol limit of 0.1 mg/100 ml applies:

Driving licence-holders who drive or operate a vehicle after they have consumed alcohol and with a blood alcohol level above the legal limit for their licence category are liable to be issued with an administrative penalty. Depending on the level of alcohol in the blood, this may be a recordable offence (Vormerkdelikt) or lead to suspension of their driving licence (if the level of alcohol in the blood is above 0.8 mg/100 ml).
