During which hours is the risk of a fatal fatigue crash about four times greater?

The answer

  • 6am to 10am
  • 10am to 2pm
  • 2pm to 6pm
  • 10pm to 6am Correct

Why that's the answer

The risk of a fatal fatigue crash is four times greater between 10pm and 6am, because that is when your body is programmed to sleep. Circadian rhythms cause it and there is nothing you can do to switch them off.
