- Drowsy driving causes thousands of fatalities and injuries every year from commercial and passenger vehicle crashes according to several transportation safety organizations. - Studies show that drowsy drivers have slower reaction times and reduced attention similar to levels of alcohol impairment. Many commercial drivers report sleeping less than 6 hours per night putting them at higher risk. - Sleep apnea, a common disorder where breathing stops during sleep, is undiagnosed in most and increases crash risk 2 to 7 times if untreated. Screening and treating sleep disorders in commercial drivers can significantly improve safety and reduce costs.
