A recent article in Insurance Journal quoted a Virginia Tech Transportation Institute study that found that 20 percent of car accidents are caused by driver fatigue. The cars in the study were equipped with video, radar, accelerometers, lane-tracking software, and an in-vehicle network sensor. The study noted that 18 to 20 year olds accounted for significantly more fatigue related crashes than any other age group. The organizers of the study further noted their surprise at the amount of fatigue related accidents during daylight hours.
The study seems to confirm what many have suspected for years, distractions, whether by intoxication, telephone use, texting, or fatigue lead to injury and death.
