Driving is hard enough without having to watch out for people who aren’t obeying the laws. For example, someone who doesn’t get enough sleep may drift between lanes or start to go off the road, which could cause a crash.

Drowsy driving is just one kind of hazard you have to watch out for on the roads. It occurs when a person doesn’t get enough sleep, takes a medication that makes him or her drowsy or has been driving so long that he or she has become bored or tired. It’s necessary for drivers to be aware of the signs that someone is driving while drowsy.

How can you recognize drowsy driving?

There are many ways to recognize drowsy driving. The most obvious is if you see someone with his or her eyes closed behind the wheel. In that case, the person may have fallen asleep behind the wheel, which clearly puts everyone at risk of a collision.

Another sign of drowsy driving is if the individual jerks to one side or the other suddenly. The driver may fall asleep for a moment and then wake up long enough to correct the vehicle.

Noticing a driver yawn or rub one’s eyes is another distinct symptom of drowsiness. If you notice a driver acting in any of these ways, it’s a good idea to call the police. They can pull the driver over and check on his or her well-being.

What can you do to prevent drowsy driving?

To prevent drowsy driving, get at least seven to eight hours of sleep before you drive. If you notice that you don’t remember recent exits or stops, pull over. Drink some caffeine or take a nap, so you feel rejuvenated and awake.

Drowsy driving is completely avoidable. If you see someone driving dangerously, report it. You could save a life.
