You have had your B licence for twelve years. At a breath check near Zwolle the police device measures the alcohol in your breath in micrograms per litre. Above which value are you punishable?
- ✓ 220 micrograms per litre
- 88 micrograms per litre
- 500 micrograms per litre
Correct answer: 220 micrograms per litre
Explanation
False — you are using the novice driver's limit. 88 micrograms per litre is the limit for a novice driver; with a licence held for twelve years you are an experienced driver and your breath limit is 220 micrograms per litre. (WVW 1994 art. 8, 163 | VekaBest p.15 (Hoofdstuk 1 §1.3))
Why learners get this wrong
- Wrong: you are using the novice driver's limit. 88 micrograms per litre is the limit for a novice driver; with a licence held for twelve years you are an experienced driver and your breath limit is 220 micrograms per litre.
- Wrong: you convert 0.5 per mille into 500 micrograms, but breath and blood each have their own limit. For an experienced driver that is 0.5 per mille in the blood and 220 micrograms per litre in the breath.
