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

You notice signs of fatigue on a long drive. What nap length works best once you have parked somewhere safe?

The answer

  • Napping does not help — keep driving
  • About 20 minutes Correct
  • About 5 minutes
  • At least 2 hours

Why that's the answer

Sleep is the only way to overcome tiredness. As soon as you notice signs of fatigue, park somewhere safe and nap — about 20 minutes works best. Do not wait for a microsleep, because by then it is too late.
