An adult driver with more than two years of licence experience drives a lorry with a MAM below 3,500 kg for ordinary goods transport, without dangerous goods or another reduced-limit case. What general maximum breath-alcohol concentration must not be exceeded?

Correct answer

0.25 milligrams per litre.

0.25 milligrams per litre of exhaled air, corresponding to the legal blood limit of 0.5 grams per litre under Article 20. A MAM below 3,500 kg alone is insufficient to apply this limit: the first two years after licensing and certain services or transport, such as dangerous goods, have a lower limit. A legal limit does not guarantee safety; the safest option is not to drink before driving.
