Core: Alcohol behind the wheel: the limit and the glass

The legal limit depends on your driving experience: an experienced driver stays under 220 micrograms per litre of breath or 0.5 promille of blood. A novice driver — the first 5 years after your first driving licence, or 7 years if you obtained an AM or T licence before turning 18 — is capped at the lower limit of 88 micrograms per litre or 0.2 promille. The book adds a consumption calculation that the law itself does not give: one standard glass, regardless of the type of drink, delivers roughly 12 ml of pure alcohol and therefore on average 0.2 to 0.3 promille. For a novice driver that one glass can already reach or exceed their own 0.2 promille limit. Breakdown happens at a fixed rate: 0.1 to 0.2 promille per hour. There is no shortcut — no coffee, no cold shower, no fresh air. Breaking down one glass therefore already takes about an hour and a half, and the limit does not apply only to car drivers: the law speaks of the driver of a vehicle, so cyclists too.
