Correct answer
0.25 milligrams per litre.
The general limit in article 20 is 0.25 mg per litre of breath in the stated case. The reduced 0.15 mg/l limit applies, among other cases, during the first two licence years and to the transport operations specified in that article. Do not confuse breath, expressed in mg/l, with blood, expressed in g/l. Alcohol may impair driving below the limit: the recommendation is not to drink if driving.
