A new study is showing the increased risk drivers take when they get behind the wheel when drowsy.
The AAA Foundation for Traffic Safety released a study, in conjunction with the Centers for Disease Control and Prevention, showing that drivers who get less than four hours of sleep a night are nearly 12 times more likely to be involved in a crash.
A recent survey from the CDC shows 35 percent of drivers sleep less than the recommended seven hours a day, while one in three admitted to being so tired while driving in the last month they have had trouble keeping their eyes open.
In addition to getting more sleep, AAA also advises drivers to travel at times when they are normally awake, schedule a break every two hours or 100 miles and travel with an alert passenger.
