Prevalence of Motor Vehicle Crashes Involving Drowsy Drivers, U.S. 2009-2013

Although official government statistics suggest that drowsy driving only contributes to approximately 1-3% of motor vehicle crashes each year in the United States, results of indepth studies suggest that the true prevalence is likely much higher. The current study updates an earlier 1999 - 2008 study with data from years 2009 – 2013. Results showed that an estimated 6% of all crashes in which a vehicle was towed from the scene, 7% of crashes in which a person received treatment for injuries sustained in the crash, 13% of crashes in which a person was hospitalized, and 21% of crashes in which a person was killed involved a drowsy driver.
