Results of a new study published by the Centers for Disease Control and Prevention might help fleet managers identify drivers who are at a higher risk for drowsy driving.

For example, the research project found that binge drinkers are more likely to drive while drowsy. So are drivers who shun seat belts. Smokers, on the other hand, are no more prone to drowsy driving than anyone else. 

Gender also is a factor. “The prevalence of drowsy driving for men aged 18-34 years was 6.9%, compared with 3.5% for women in the same age group,” reported the study.
