About Alcohol behind the wheel: the limit and the glass: which statement is WRONG?
- One standard glass contains about 12 ml of pure alcohol and produces on average 0.2 to 0.3 promille.
- The limit applies to the driver of a VEHICLE, and a bicycle is a vehicle.
- ✓ For an experienced driver the breath limit is 88 micrograms per litre.
- The body breaks down alcohol at a fixed rate of 0.1 to 0.2 promille per hour, regardless of coffee or water.
Correct answer: For an experienced driver the breath limit is 88 micrograms per litre.
Explanation
220 micrograms per litre is the limit for the experienced driver; 88 micrograms per litre applies to the novice driver. The two figures are swapped
Why learners get this wrong
- One standard glass contains about 12 ml of pure alcohol and produces on average 0.2 to 0.3 promille. For a novice driver (limit 0.2 promille) that one glass can already exceed the legal limit
- The limit applies to the driver of a VEHICLE, and a bicycle is a vehicle. Only the lowered novice limit (0.2 promille) is restricted to licence-requiring motor vehicles
- The body breaks down alcohol at a fixed rate of 0.1 to 0.2 promille per hour, regardless of coffee or water. Breaking down 1 glass therefore already takes about 1.5 hours; only time lowers the promillage
