A)0.50 milligrams per litre.
B)0.25 milligrams per litre.
C)0.15 milligrams per litre.Correct
The maximum permitted blood alcohol levels are: - Minors: 0.0. - Professionals and novice drivers (first 2 years of their licence): 0.15 milligrams per litre in exhaled air or 0.30 grams per litre in blood. - All other drivers (including cyclists and personal mobility vehicle users): 0.25 milligrams per litre in exhaled air or 0.50 grams per litre in blood. IMPORTANT: even if you drive with a level below the maximum, it is already possible to have an accident due to the effects of alcohol (the only safe level is 0.0 g/l). Do not confuse the obligation to display the "L" sign on the vehicle, which applies for 1 year, with the reduced alcohol level, which applies for 2 years.
