New South Wales · Driver Knowledge Test (DKT) · Road safety

What actually reduces your blood alcohol concentration?

The answer

  • Only time Correct
  • Black coffee
  • A cold shower
  • A large meal

Why that's the answer

The only thing that reduces your BAC is time. There is no way to speed up how fast your body gets rid of alcohol — black coffee, a shower and a large meal will not work.
