Area officials confirm drowsy driving can be a problem, but a hard one to determine.

According to a recent report by the Centers for Disease Control and Prevention (CDC), one in 24 adult drivers in the United States admit to falling asleep while driving.

The CDC report states the percentage of adults driving in a drowsy state could be even higher because many people do not notice when they nod off for a few seconds while driving. The report was based on a questionnaire distributed in 2009-10, with 147,076 respondents in 19 states and the District of Columbia.
