BDifficulty 2/5

An adult driver, within two years of obtaining their first driving licence, records 0.20 mg/l of alcohol in exhaled air. Must the officer carry out a second test?

Correct answer

Yes, for greater assurance and for comparison purposes.

Yes. Article 20 sets a maximum of 0.15 mg/l in exhaled air for this driver: 0.20 mg/l exceeds it, rather than being below the limit. Article 23 requires a second breath test for greater assurance and comparison, informing the person beforehand. At least 10 minutes must elapse between the tests. This does not depend on a crash and is not merely a recommendation because of inexperience.
