BDifficulty 2/5

As a usual guide, when does blood alcohol concentration tend to reach its maximum after drinking?

Correct answer

From 30 to 90 minutes after consuming the alcoholic drink.

It usually peaks between 30 and 90 minutes after drinking. This describes absorption and blood alcohol concentration, not the driver’s reaction time or a period when drinking is harmless. Timing varies with factors including amount, drinking rate and food. Effects may begin before the peak and persist afterwards; feeling recovered or waiting a fixed interval does not guarantee fitness to drive. The safe choice is not to drink if you will drive.
