Thousands of crashes occur each year because drivers falling asleep at the wheel. Learn the signs so that you know when you are getting drowsy, what puts you at risk for drowsy driving, and what to do to stay alert.
What Are the Signs of Sleepiness?
The AAA Foundation for Traffic Safety provides some warning sign to help you identify when you are getting too tired to drive. If you begin to experience any of these, it is time to stop driving and get some sleep:
Are You at Risk?
To determine if you are at an increased risk for a sleep-related traffic accident, the AAA Foundation for Traffic Safety asks the following questions:
If you can answer yes to any of these questions, you are at a higher risk of having a car accident related to being tired.
In addition, analysis of sleepy driver crashes shows that having taken sedating medications on a previous night was associated with subsequent crash. If you spend time on the road, don’t use medications that could produce rebound sleepiness the next day.
What Can You Do?
Here are some things you can do to prevent drowsy driving:
Note: If you are relying on coffee to keep you awake, it is time to pull over and call it a night. The best strategy is to take a break from being behind the wheel.
If you suspect you have a sleeping disorder, talk to your doctor about your symptoms so you can get proper treatment.
In the meantime, it is important to remember that driving when sleepy may be as dangerous as drunk driving—for you and for others on the road.
