Can I drive after one Beer 25cl?
After a single serving, the estimated peak is 0.10 g/L for an 80 kg man and 0.22 g/L for a 60 kg woman. Legal limit: 0.5 g/L in Switzerland and France, but 0.2 g/L on a French probationary licence and 0.1 g/L for new drivers in Switzerland. These values are theoretical and never a guarantee: only a breathalyser can tell. When in doubt, do not drive.
The values shown are theoretical estimates based on the Widmark formula (30 min absorption, elimination of 0.15 g/L/h for men and 0.12 g/L/h for women, on an empty stomach). Actual blood alcohol varies with the individual, food, tiredness or medication. This information is no substitute for a breathalyser or medical advice. Alcohol abuse is dangerous for your health.
