Drowsiness a significant risk to drivers, and it’s one that can be extremely dangerous on the roads. Though there are other reasons for crashes, drowsiness is a leading cause of collisions in America.

Most people don’t plan to drive when they’re exhausted or tired, but sometimes, they feel they don’t have a choice. Whether it’s for work or because of other responsibilities, they may choose to drive when they’d be better off staying at home. Taking that risk could result in a serious collision, which then could cause fatalities or catastrophic injuries to the victims.

Among the most at-risk drivers are those who drive commercial vehicles.

Sleep deprivation that results from trying to meet tight deadlines is just one of the reasons why a driver might fall asleep or feel drowsy behind the wheel.
