Safety Tips

  • Maintain a regular sleep schedule that allows adequate rest.
  • When the signs of fatigue begin to show, get off the road. Take a short nap in a well-lit area. Do not simply stop on the side of the road.
  • Avoid driving between 12am and 6am

When planning long trips:

  • Share driving responsibilities with a companion
  • Begin the trip early in the day
  • Keep the temperature cool in the car
  • Stop every 100 miles or 2 hours to get out of the car and walk around; exercise helps to combat fatigue
  • Stop for light meals and snacks
  • Drive with your head up, shoulders back and legs flexed at about a 45 degree angle
