BDifficulty 2/5

An adult car driver obtained their first qualifying driving permit less than two years ago. What is their maximum breath-alcohol level?

Correct answer

0.15 milligrams of alcohol per litre of exhaled air.

0.15 milligrams per litre of exhaled air, corresponding to the article 20 blood limit of 0.3 grams per litre in this case. The period runs for two years from obtaining the qualifying permit or licence; licence seniority counts only for vehicles for which that licence suffices. The question excludes underage drivers, whose limit is zero under article 14 of the Traffic Act. The 0.3 mg/l option confuses units and measurement media. The safest choice when driving is to consume no alcohol.
