BDifficulty 2/5

An adult driver has just obtained their first driving licence. During the following two years, what breath-alcohol concentration must they not exceed?

Correct answer

0.15 mg/l of breath.

0.15 mg per litre of breath, corresponding to the legal blood limit of 0.30 g per litre under Article 20. These are different samples and units: this is not a blood concentration expressed in breath mg/l. The question specifies an adult; underage drivers have a zero limit under Article 14 of the Traffic Act. Lower limits may still apply after the novice period because of the transport category. Staying within a limit does not guarantee safe driving: avoid drinking when driving.
