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

How long should you wait after waking up before you drive?

The answer

  • About 30 minutes Correct
  • At least 2 hours
  • There is no need to wait
  • About 5 minutes

Why that's the answer

Wait 30 minutes after waking before driving. The risk of fatigue is high immediately after you wake, while you still feel tired — this is 'sleep inertia', and it generally lasts 15 to 30 minutes.
