1 in 24 adults in the US have confessed that they doze off while driving, a study has revealed.
Health officials, who conducted the study, believe that the number is probably higher, as some people don't realize it when they nod off for a second or two behind the wheel.
Anne Wheaton of the Centers for Disease Control and Prevention's (CDC) study released on Thursday, found that about 4 percent of adults said that they nodded off or fell asleep at least once while driving in the previous month, Fox News reported.
CDC telephone surveyed 147,000 adults and conducted the study in 19 states and the District of Columbia in 2009 and 2010.
CDC researchers found that drowsy driving was more common in men, people in the age group of 25 - 34, those who averaged less than six hours of sleep each night, and - for some unexplained reason - Texans.
The government estimated that about 3 percent of fatal crashes involved drowsy drivers, but other estimates put that number as high as 33 percent.
To prevent drowsy driving, health officials recommend getting 7 to 9 hours of sleep every night, treating any sleeping disorders and not drinking any alcohol before getting behind the wheel. (ANI)
