Drowsy Driving

Drowsy Driving, How big is the problem?

“a national problem…One in four Americans didn’t get enough sleep last night.”
— Wake Up America: A National Sleep Alert Report of the National Commission on Sleep Disorders Research.

Accident attrIn every state, 40-60% of all traffic accidents with determined causes are a direct or partial result of drift-off. Nationwide, drift-off is the number one factor in both non-alcohol and alcohol-related highway accidents (SOURCE: NHTSA and state DOT reports).

The annual costs of motor vehicle accidents in the United States are staggering. Just in accidents involving an injury or fatality, the costs rose to nearly $170 billion annually in 1993. And these costs do not account for the loss in quality of life for such accidents.

  • One-third of motorists have fallen asleep behind the wheel.
  • 12% of motorists who have fallen asleep have had an accident as a result.
  • Over half of American motorists drive when they are too tired to get behind the wheel.
  • 23% percent of adults know someone who experienced a fall-asleep crash within the past year.

Factors contributing to injury and fatality accidents

Highways across the country have begun to re-examine factors contributing to injury and fatality accidents. Consistently, one message has become clear: every highway has a problem with run-off accidents.
