Prije te zabrane, vozaču je bilo dozvoljeno popiti malo pivo ili čašu vina, što bi iznosilo maksimalno 0,5 promila alkohola u krvi, ali novom mjerom zahtijevalo se da vozači imaju 0,0 promila alkohola u krvi.
Before the ban, a driver was allowed to drink either a small beer or a glass of wine, for a maximum of 0.5 per ml of blood alcohol, but the new measure demanded drivers have 0.0 per ml of blood alcohol.
