When is the risk of a fatal fatigue-related crash greatest?

The answer

  • Late at night and early in the morning Correct
  • The risk is the same at all hours
  • Mid-morning
  • Early afternoon

Why that's the answer

The risk of a fatal fatigue-related crash is four times greater late at night and early in the morning — the hours when your body naturally wants to sleep. Avoid driving when you would normally be asleep.
