Drowsy Driving/Fatigue

General Statistics

  • Teen drivers who sleep less than 8 hours nightly are one-third more likely to crash than those who sleep 8 or more hours nightly.1

  • Drowsiness is similar to alcohol in how it compromises driving ability by reducing alertness and attentiveness, delaying reaction times, and hindering decision-making skills.2

  • Daily sleep is reduced by about 40 to 50 minutes from ages 13 to 19. This is caused by gradually later bedtimes but more or less stable awakening times.2
  • Teens need to log a little more than nine hours of sleep per night to achieve the optimal level of daytime alertness needed to eliminate the risk of drowsy driving.2

  • The majority of fatigue-related crashes are caused by drivers under age 25.3
  • Being awake for 18 hours is similar to having a blood alcohol concentration (BAC) level of 0.08, which is legally drunk.4

  • At least 5 percent of adults (ages 18 to 44) admit to falling asleep at the wheel.5

  • Approximately 1 in 5 fatal crashes include a drowsy driver and 16- to 24-year-old drivers are the most likely to be involved in these crashes.5

  • In 2009, over 30,000 crashes involved drowsy driving.5
