BDifficulty 2/5

An adult driver obtained their first driving licence one year ago and drives a car. With no earlier qualifying entitlement, what maximum breath-alcohol level does article 20 establish?

Correct answer

0.15 milligrams per litre of exhaled air.

0.15 mg per litre of exhaled air; the equivalent blood limit is 0.3 g per litre during the two years following the qualifying licence or permit, subject to article 20’s rules for counting prior entitlement. An underage driver’s limit is zero, so this scenario specifies an adult. Being within a legal limit does not guarantee safe driving: avoid drinking if you will drive.
