Can you still drive after a glass of wine?
Basically, you should not drink alcohol if you drive a car afterwards. However, Swiss law leaves a small amount of leeway. How quickly is alcohol broken down in the body and does greasy food really help?
If my grandfather had said to his friends 50 years ago after a long dinner with two glasses of wine that he would rather leave the car parked, they would probably have looked at him askance.
Today it's exactly the opposite: If I said after two glasses of wine that I'd drive home in my own car, I'd be looked at just as obliquely. The times have changed.
What does the Swiss law say?
The legal limit for breath or blood alcohol levels has been adjusted over the years.
Today, the following rule applies: anyone who drives a motor vehicle or steers a leisure or sports ship in Switzerland with a breath or blood alcohol level of 0.25 mg/l or 0.50 per mille or more must expect legal consequences that hand to jail.
How quickly is alcohol broken down in the body?
Basically, the breakdown rate of alcohol in the body is linear, i.e. like a gondola in the mountains, which moves from mast to mast at the same speed. The liver starts this process a few minutes after the first sip.
The liver breaks down about 0.1 grams of alcohol per kilogram of body weight per hour (about 0.13 per thousand). For a man weighing 80 kg, this roughly corresponds to the amount of alcohol contained in a small glass of wine (0.1 l), assuming the wine has an alcohol content of around 12% vol. Read More…
