California drivers may be interested to learn that newer technologies are making driving safer. Companies such as Volvo and BMW are introducing devices that help detect when a driver may be getting drowsy and alert the motorist to that possibility.
While it is difficult to measure fatigue as a factor in car accidents due in part to the fact that there is no test for drowsiness as there is for drunk driving, it is estimated that at least 7,500 fatal accidents each year have fatigue as a factor. It was considered one likely cause of the 2014 accident that seriously injured comedian Tracy Morgan and killed another passenger in his limousine. The truck driver who hit them had been awake for 28 hours.
