A new study suggests that driving on five hours of sleep is like driving drunk.

FOX's Jeff Monosso reports: 

The Triple-A Foundation for Traffic Safety finds that drivers who skimp on just a couple of hours of sleep, nearly double the risk of a crash, making drowsy driving about as dangerous as drunk driving.

A review of thousands of crashes, resulting in injuries, found drivers were 1.3 times more likely to be involved in a crash if they missed an hour of sleep and 1.9 times more likely to be involved in a crash if they missed two of the seven hours recommended daily sleep.

The Centers for Disease Control and Prevention says about 1/3 of U.S. drivers get less than seven hours of sleep every night.
