A1Difficulty 3/5

After drinking beer or wine, your breath alcohol concentration is 0.15 mg per litre. Can that alcohol affect your motorcycle riding?

Correct answer

Yes; it can increase reaction time and impair riding.

Yes. Alcohol can impair attention, coordination and decision-making and increase reaction time, even at low concentrations. Longer reaction time means travelling farther before braking begins at the same speed; it does not mean alcohol improves the brakes or shortens stopping distance. The specific effect varies between people and circumstances. Meeting a legal limit does not guarantee unimpaired driving: if you will drive, the safe choice is not to consume alcohol.
