Frequently Asked Questions

What is the legal blood alcohol limit?

The legal limit is 0.5 g/L of blood (0.25 mg/L of breath). For new drivers (license less than 3 years), the limit is 0.2 g/L.

How long does it take to eliminate alcohol?

The body eliminates about 0.10 to 0.15 g/L per hour. A heavy meal slows absorption but not elimination. Only time allows alcohol to be eliminated.

What are the risks of a positive test?

Between 0.5 and 0.8 g/L: €135 fine and 6 points withdrawal. Above 0.8 g/L: criminal offense with €4500 fine and license suspension.

How is blood alcohol level calculated?

The Widmark formula takes into account weight, sex, amount of alcohol consumed and time elapsed. A standard drink (10g of alcohol) increases the level by about 0.20 g/L.

Can you speed up alcohol elimination?

No, no remedy (coffee, cold shower, exercise) speeds up alcohol elimination by the liver. Only time is effective.
