Drowsy driving is a lot like drunk driving. A sleepy driver scans the road less, has slower reaction times, and generally does not pay enough attention to the surroundings, just like a driver impaired by alcohol. A driver who is awake for 18 hours will drive similarly to someone with a .05% blood-alcohol content. A driver who’s been awake for 24 hours, mimics a driver with a 0.10% alcohol level, which is above the legal limit of 0.08%.

The dangers of drowsy driving

According to the AAA Foundation for Traffic Safety, at least 20 percent of all fatal crashes on U.S. roadways each year involve drowsy driving. And, the National Highway Traffic Safety Administration (NHTSA) estimates that in 2017 alone, approximately 91,000 traffic accidents occurred nationwide from drowsy driving, resulting in 50,000 injuries and 800 deaths. These statistics only reflect accidents that were reported to police. The NHTSA, along with public health communities and sleep scientists agree drowsy driving is significantly underreported in the United States.
