Sleepiness is a factor in nearly 17 percent of all fatal car crashes, causing more than 5,500 traffic deaths per year, according to a new analysis by the AAA Foundation for Traffic Safety.
The group studied National Highway Traffic Safety Administration data from 1999 through 2008 and found a much higher incidence of drowsy driving in fatal crashes than in earlier studies. A 1994 analysis determined it was a factor in only 3.6 percent of fatal crashes.
“Many of us tend to underestimate the negative effects associated with fatigue and sleep deprivation,” Kathleen Marvaso, a vice president with AAA, told the Los Angeles Times.
The analysis also included a survey of more than 2,000 drivers across the country. According to the results, 41 percent of drivers reported falling asleep or nodding off while driving at some point in their lives, while 11 percent said it had happened to them in the last year.
The survey also found that men are 61 percent more likely to have been drowsy at the time of a crash than women. Drivers between 16 and 24 are 78 percent more likely to report being sleepy prior to an accident than drivers between 40 and 59.
According to the authors of the study, estimates on the incidence of drowsy driving and its role in accidents vary widely, but they believe it does not receive as much attention as other leading causes of crashes.
To avoid drowsy driving altogether, AAA recommends that drivers get at least 6 hours of sleep before long trips, take breaks every 100 miles and travel with an alert passenger.



My brother has been reported to sleep-drive, but c’est-la-vie, there’s nothing I can do about it.
