1. Drowsy driving is greatly underreported because there is no test for it, as there is for intoxication, no clear way to identify it, and many states don't even have a code for it on their vehicle accident reporting forms. The U.S. National Highway Traffic Safety Administration (NHTSA) estimates that about 100,000 police-reported crashes annually involve drowsiness/fatigue as a principal cause. It estimates that these crashes cause $12.5 billion in monetary losses each year. Sleepiness and fatigue also play a role in crashes attributed to other causes. About 1,000,000 crashes annually -- one-sixth of all crashes -- are thought to be caused by driver inattention adn lapses. Sleep deprivation and fatigue make such lapses of attention more likely to occur. In a 1999 National Science Foundation poll, 62% of all adults surveyed in the U.S. reported driving a car or other vehicle while they were drowsy during the previous year. Twenty-seven percent reported that they had, at some time, fallen asleep while driving. People are more likely to fall asleep on high-speed, long, boring, rural highways. The New York State Police estimates that 30% of all fatal accidents on the New York State Thruway occur because drivers fall asleep at the wheel. Studies suggest truck driver fatigue may contribute to at least 30 to 40% of all heavy truck accidents. (Facts about Drowsy Driving.
