BDifficulty 2/5

After someone stops drinking alcohol, can it be guaranteed that their blood-alcohol level starts falling exactly one hour later?

Correct answer

No; timing varies, and blood-alcohol levels can continue rising.

No. Timing and progression vary with the person, amount consumed, absorption and factors such as food. The DGT explains that peak concentration is usually reached 30–90 minutes after ingestion; this indicative interval does not establish a universal hour after the last drink or guarantee fitness to drive. Blood-alcohol levels can continue rising after drinking stops. Avoid alcohol when driving.
