DDifficulty 2/5

For an adult driver of a bus intended for passenger transport with more than nine seats including the driver’s seat, what breath-alcohol concentration must not be exceeded?

Correct answer

0.15 milligrams of alcohol.

0.15 milligrams per litre of exhaled air under Article 20 of the General Traffic Regulations; the corresponding blood limit is 0.3 grams per litre. Seat count means vehicle capacity, not the passengers aboard at that moment. These limits do not make driving after drinking safe: zero alcohol is the safest choice.
