A new study by the U.S. Department of Transportation looks at the relationship between sleep deprivation and crash risk in the general driving population. More specifically, this study examines crashes that occurred in the United States between 2005 and 2007 involving at least one vehicle towed due to damage and an emergency medical services dispatch. Part of the investigations into each accident involved an assessment of the drivers’ recent sleep. The study included more than 7,200 drivers who were involved in over 4,500 crashes.
The results of the study showed that drivers who usually slept for less than five hours daily, drivers who slept for less than seven hours in the past 24 hours, drivers who slept for one or more hours less than their usual amount of sleep in the past 24 hours have much higher crash rates than other drivers. Using the general recommendation that healthy adults should sleep for at least seven hours per day, the data indicated that driving after only four or five hours of sleep is similar to the risk of crashing of a driver with a blood alcohol concentration equal to or slightly above the legal limit for alcohol. Those drivers who slept for four hours or less had much higher crash rates than other drivers.
More specifically, when a driver had less than four hours of sleep in the past 24 hours, he or she had 11.5 times the crash rate as a driver who had slept for seven hours or more. Likewise, if a driver had between four and five hours of sleep, he or she had 4.3 times the crash rate as a driver who had slept for seven hours or more. A driver with between five and six hours of sleep had a crash rate that was 1.9 times that of a driver who had slept for seven hours or more, and a driver with between six and seven hours of sleep had a crash rate that was 1.3 times that of a driver who had slept for seven hours or more.
