How dangerous is drowsy driving?
As part of the AAA Foundation’s survey, 96 percent of drivers said they see drowsy driving as “completely unacceptable” behavior that threatens their safety. Even so, almost 1 in 3 also admitted that, at some point in the previous month, they themselves had driven while having a hard time keeping their eyes open.

It's difficult to measure the proportion of crashes that are related to drowsy driving, as drivers may not want to reveal that they were driving while fatigued. And unlike drugs and alcohol, there's no way to test for fatigue after a crash. By examining dashcam footage from more than 700 crashes and analyzing the percentage of time that drivers' eyes were closed, research from the AAA Foundation for Traffic Safety found that 9.5 percent of all crashes, and almost 11 percent of crashes that led to significant property damage, involved drowsiness. This is far higher than the federal estimate of 1-2 percent.
