Fatigue in the car

When you are tired, you are less alert. The body naturally becomes fatigued at the end of the day, and this increases as the night continues. You may not see hazards or react as quickly, so the chance of a collision is greater. If you are drowsy, the only safe choice is to get off the road and get some sleep. If you don't, you risk your life and the lives of others.


  • Get a lot of rest before you start—at least a normal night's sleep.
  • Don't take any drugs that can make you drowsy—even the night before you start.
  • Don't drive long hours. Driving "straight through" can be dangerous if you are tired and sleepy.
  • Try not to drive late at night. Your body is used to going to sleep at that time.
  • Change drivers at regular intervals.
Freeway from the car
  • Keep your eyes moving.
  • Roll your window down and get some fresh air.
  • Stop at a rest area and do some stretching exercises.
  • If you notice any sign of fatigue, the safest course of action is to stop and sleep. If no motels, rest areas or truck stops are nearby, pull off the road in a safe, well-lit area, lock your doors and take a nap. Even 30 minutes of sleep can refresh you enough to keep going until you reach a safe rest area.
