You may believe that you can stop yourself from falling asleep when you are driving drowsy, but you can’t. You may not even know you’ve dozed off. This is more likely to happen if you are sleep-deprived, driving long distances without rest breaks, traveling at night, driving alone, riding long rural highways, taking medicine that causes sleepiness, or drinking alcohol.
Try these tips from the National Highway Traffic Safety Administration:
Never drink and drive. Alcohol reduces your driving ability and worsens tiredness. It’s also illegal to drive under the influence of alcohol.
If possible, don’t drive long distances alone. If you have a companion on your drive, you’ll have someone to talk with. Plus you can take turns driving.
Take a break at least every 2 hours. Stop in a place that is safe and well-populated to walk around and stretch.
Have 2 cups of a caffeinated drink like coffee, if you can have caffeine.
