BDifficulty 2/5

An adult obtained their first driving licence 18 months ago, with no previous authorisation counting towards experience. Under article 20, what blood alcohol level must they not exceed while driving?

Correct answer

0.3 grams per litre of blood.

0.3 grams per litre of blood during the two years following acquisition of the authorisation permitting driving. The corresponding breath limit is 0.15 milligrams per litre: these are different units and samples. Drivers under 18 have a zero limit. Being below the limit does not guarantee fitness or safety; avoid alcohol if driving.
