Correct answer
0.15 milligrams per litre of exhaled air
0.15 mg/l of breath, corresponding to the 0.3 g/l blood limit under Article 20. This is a legal limit, not a recommended level for driving: the safe choice is zero alcohol. Drivers under 18 have a zero limit. Do not confuse breath units with blood units.
