A study conducted by the American Automobile Association (AAA) has revealed that a drowsy driver behind the wheel faces the same risk as a drunk driver.
The AAA said that its study of 4,571 accidents that took place in the US showed that drivers who got less than 7 hours (recommended) of sleep a day face higher accident risks.
David Yang, the Executive Director for the AAA Foundation for Traffic Safety, said in a statement that "You cannot miss sleep and still expect to be able to safely function behind the wheel."
Drivers who have had only two to three hours of sleep in a period of 24 hours face four times the risk of an accident compared to a driver who has had 7 hours of sleep. This is the same amount of risk a drunk driver faces, according to the National Highway Traffic Safety Administration (NHTSA).
Also, drivers who are short of one or two hours of sleep face two times the risk of meeting with an accident compared to those who've had 7 hours of sleep. The study also revealed other aspects, like 35 percent of drivers in the US sleep for less than 7 hours a day and almost one fifth of fatal accidents involved sleep-deprived drivers.
The report, as per Reuters, are based on figures from the National Highway Traffic Safety Administration covering accidents between July 2005 and December 2007.
