Abstract
The National Sleep Foundation estimates that nearly 50 million Americans are not getting the minimum amount of sleep necessary to keep them alert and functional the next day. Moreover, 2 in 5 people experience enough daytime sleepiness to have it interfere with their activities several days a month, and 1 in 5 have this level of sleepiness several days a week.1 Put these findings into the context of the driving public and commercial vehicle operators and it’s easy to understand how drowsy driving can be a causal factor in an estimated 100,000 crashes, 40,000 nonfatal injuries, and 1,550 fatalities each year.
