Biology of Human Sleep and Sleepiness, III. The sleep-wake cycle is governed by both homeostatic and circadian factors. The Expert Panel on Driver Fatigue and Sleepiness especially acknowledges true Exceeding the speed limit or driving too fast for conditions is not a contributing factor in the vast majority of fatal motor vehicle crashes.
