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

How much sleep does the average person need each night to function normally?

The answer

  • About 6 hours
  • About 8 hours Correct
  • About 11 hours
  • About 5 hours

Why that's the answer

The average person needs about 8 hours a night, and teenagers need more. Getting less builds a 'sleep debt', and the only way to treat sleep debt is by sleeping.
