What is Drowsy Driving?
Operating a motor vehicle while fatigued or sleepy is commonly referred to as “drowsy driving.”


The Impact of Drowsy Driving
Drowsy driving poses a serious risk not only for one’s own health and safety, but also for the other people on the road.
The National Highway Traffic Safety Administration estimates1 that between 2005 and 2009 drowsy driving was responsible for an annual average of:

  • 83,000 crashes
  • 37,000 injury crashes
  • 886 fatal crashes (846 fatalities in 2014)

These estimates are conservative, though, and up to 6,000 fatal crashes each year may be caused by drowsy drivers.2-4


How Often Do Americans Fall Asleep While Driving?

  • Approximately 1 out of 25 adults aged 18 years and older surveyed reported that they had fallen asleep while driving in the past 30 days.5,6
  • Individuals who snored or slept 6 hours or less per day were more likely to fall asleep while driving.

How Does Sleepiness Affect Driving?
