Attitudes About Drowsy Driving Need to Change

Traffic Safety Facts Drowsy Driving

Fatigue has costly effects on the safety, health, and quality of life of the American public. Whether fatigue is caused by sleep restriction due to a new baby waking every couple of hours, a late or long shift at work, hanging out late with friends, or a long and monotonous drive for the holidays – the negative outcomes can be the same. These include impaired cognition and performance, motor vehicle crashes, workplace accidents, and health consequences.

Tackling these issues can be difficult when our lifestyle does not align with avoiding drowsy driving. In a 24/7 society, with an emphasis on work, longer commutes, and exponential advancement of technology, many people do not get the sleep they need. Effectively dealing with the drowsy-driving problem requires fundamental changes to societal norms and especially attitudes about drowsy driving.

The terms drowsy, sleepy, and fatigue are used interchangeably although there are differences in the way these terms are used and understood.

Precise Numbers of Drowsy-Driving Crashes, Injuries, and Fatalities Are Hard to Nail Down

Unfortunately, determining a precise number of drowsy-driving crashes, injuries, and fatalities is not yet possible. Crash investigators can look for clues that drowsiness contributed to a crash, but these clues are not always identifiable or conclusive.

NHTSA’s census of fatal crashes and estimate of traffic-related crashes and injuries rely on police and hospital reports to determine the incidence of drowsy-driving crashes. NHTSA estimates that in 2017, 91,000 police-reported crashes involved drowsy drivers. These crashes led to an estimated 50,000 people injured and nearly 800 deaths.But there is broad agreement across the traffic safety, sleep science, and public health communities that this is an underestimate of the impact of drowsy driving.

The Issue

Sleepiness can result in crashes any time of the day or night, but three factors are most commonly associated with drowsy-driving crashes.

Drowsy-driving crashes:

  1. Occur most frequently between midnight and 6 a.m., or in the late afternoon. At both times of the day, people experience dips in their circadian rhythm—the human body’s internal clock that regulates sleep;
  2. Often involve only a single driver (and no passengers) running off the road at a high rate of speed with no evidence of braking; and
  3. Frequently occur on rural roads and highways.

  1. Getting adequate sleep on a daily basis is the only true way to protect yourself against the risks of driving when you’re drowsy. Experts urge consumers to make it a priority to get seven to eight hours of sleep per night.For more information on healthy sleep, see In Brief: Your Guide to Healthy Sleep(PDF, 1.81 MB) atthe National Heart, Lung, and Blood Institute website.
  2. Before the start of a long family car trip, get a good night’s sleep, or you could put your entire family and others at risk.
  3. Many teens do not get enough sleep at a stage in life when their biological need for sleep increases, which makes them vulnerable to the risk of drowsy-driving crashes, especially on longer trips. Advise your teens to delay driving until they’re well-rested.
  4. Avoid drinking any alcohol before driving. Consumption of alcohol interacts with sleepiness to increase drowsiness and impairment.
  5. Always check your prescriptionand over-the-counter medication labels to see if drowsiness could result from their use.
  6. If you take medications that could cause drowsiness as a side effect, use public transportation when possible.
  7. If you drive, avoid driving during the peak sleepiness periods (midnight – 6 a.m. and late afternoon). If you must drive during the peak sleepiness periods, stay vigilant for signs of drowsiness, such as crossing over roadway lines or hitting a rumble strip, especially if you’re driving alone.

SHORT-TERM INTERVENTIONS

  1. Drinking coffee or energy drinks alone is not always enough. They might help you feel more alert, but the effects last only a short time, and you might not be as alert as you think you are. If you drink coffee and are seriously sleep-deprived, you still may have “micro sleeps” or brief losses of consciousness that can last for four or five seconds. This means that at 55 miles per hour, you’ve traveled more than 100 yards down the road while asleep. That’s plenty of time to cause a crash.
  2. If you start to get sleepy while you’re driving, drink one to two cups of coffee and pull over for a short 20-minute nap in a safe place, such as a lighted, designated rest stop. This has been shown to increase alertness in scientific studies, but only for short time periods.

NHTSA In Action

NHTSA demonstrates its commitment to eliminating drowsy driving on our nation’s roads by working with the Centers for Disease Control and Prevention and the National Institutes of Health to expand our understanding of drowsy driving so we can reduce related deaths and injuries and help people avoid becoming a drowsy-driving statistic.

Other efforts include:

  • In 2016, NHTSA released a strategic plan, Drowsy Driving and Research Program Plan (PDF, 613 KB), addressing six broad focus areas: Measurement and Problem Identification, Public Awareness and Education, Policy Development, High-Risk Populations, Vehicle Technology, and Infrastructure.
  • In 2015, NHTSA convened the forum Asleep at the Wheel: A Nation of Drowsy Drivers (PDF, 1.66 MB) during the National Sleep Foundation’s National Drowsy Driving Prevention Week. This meeting included more than 100 participants from many diverse organizations, setting the stage for a national coordinated effort by bringing together motor vehicle and highway safety experts with sleep/circadian science experts and the sleep medicine community.
