To be a safe driver you must be well rested and alert. Driver fatigue and falling asleep at the wheel are factors in many crashes that cause death and injury, and most "stay awake" tricks don't work.

Tips to avoid a fatigue-related crash:

  • Get enough sleep before a trip
  • If you're drowsy, don't drive: pull over to a safe area and take a short nap
  • Take a mid-afternoon break
  • Avoid driving in the early morning and late at night
  • Talk to a passenger and change drivers, or listen to talk radio or a talking book

Nap length that can make a big difference when you're drowsy

Signs of driver fatigue:

  • Falling asleep at stop signs, yawning, heavy eyelids
  • Difficulty remembering the last few miles driven
  • Missing road signs or making unplanned lane changes
  • Head nodding, driving off the road, or hitting rumble strips
Handbook p. 74 ↗

What does NOT prevent drowsiness:

  • Rolling down a window
  • Chewing gum
  • Turning up the radio
  • Caffeine, energy drinks and other stimulants (not reliable)
  • Talking on a cell phone or texting (never use these to stay awake)
Handbook p. 74 ↗

Know the rule

Rumble strips exist to wake you up: their vibration and sound alert drowsy or inattentive drivers who leave the travel lane or approach a stop sign or signal.

Handbook p. 54 ↗

Put it into practice

Two hours into a night drive, you drift onto the rumble strip. Turning up the radio won't fix it. Pull off at the next safe spot and take a short nap, or let your passenger drive.
