- Regardless of your destination, getting somewhere in a hurry is not worth your or someone else’s life. If feeling drowsy pull off the road at a rest stop or gas station and take a nap. A 15 to 20 minute nap at a well lit buys gas station or rest area is safest, especially if traveling at night.
- Once you have rested your eyes, get some caffeine such as coffee or an energy drink and engage in physical activity such as a brief walk.
- Do not start driving again until you feel refreshed.

- Get a good night’s sleep the night before you begin a long road trip.
- Do not begin a road trip during the “midday slump” or in the evening.
- Do not plan to drive for more than 10 hours.
- Plan to stay overnight if your trip requires you to drive at night time.
- Plan for traffic and unpredictable delays by allowing extra time for your trip.
- Plan to stop every 100 miles or so at a gas station or rest stop. Be sure to stretch your legs and move around. Be sure to get snacks or drinks at stops to keep energized.
- Plan to drive with someone else. Sharing the driving can take a lot of the stress off the driver and make the drive less monotonous.
- Drive during times you are usually awake. Darkness triggers melatonin production in the brain which can cause drowsiness.
- Make the car environment somewhat uncomfortable. Keep the air cool and the music louder and more upbeat. Soft music can lull you to sleep.
- Do not drive if you have untreated sleep disorders.

(I know I’m guilty of this). With driving being as unpredictable as it is because of other drivers, weather and car functions, any lack in alertness can contribute to potentially fatal accidents.
