Drivers are Falling Asleep Behind the Wheel
Drowsy Driving Prevention Week, held every year during the first full week of November, is a good time to remember that drowsy driving is impaired driving.
According to the Centers for Disease Control and Prevention, about 1 in 25 adult drivers report having fallen asleep while driving in the previous 30 days, and many more admit to driving when they were sleep-deprived.
These startling figures show how prevalent drowsy driving is. What drivers may not realize is how much drowsy driving puts themselves – and others – at risk. In fact, an estimated 6,400 people died annually in crashes involving drowsy driving, according to the National Sleep Foundation.
Driving while drowsy is similar to driving under influence of alcohol:
A driver might not even know when he or she is fatigued because signs of fatigue are hard to identify. Some people may also experience micro-sleep – short, involuntary periods of inattention. In the 4 or 5 seconds a driver experiences micro-sleep, at highway speed, the vehicle will travel the length of a football field.
The National Highway Traffic Safety Administration estimates that every year about 100,000 police-reported, drowsy-driving crashes result in nearly 800 fatalities and about 50,000 injuries. The real number may be much higher, however, as it is difficult to determine whether a driver was drowsy at the time of a crash.
A study by the AAA Foundation for Traffic Safety estimated that 328,000 drowsy driving crashes occur annually. That's more than three times the police-reported number. The same study found that 109,000 of those drowsy driving crashes resulted in an injury and about 6,400 were fatal. The researchers suggest the prevalence of drowsy driving fatalities is more than 350% greater than reported.
Beyond the human toll is the economic one. NHTSA estimates fatigue-related crashes resulting in injury or death cost society $109 billion annually, not including property damage.
Drowsy driving affects everyone, but especially those under age 25, who make up an estimated 50% or more of drowsy driving crashes. That means interventions focusing on this age group – males especially – can help reduce drowsy driving among those vulnerable. One such intervention is for parents to incorporate discussions and rules on drowsy driving while completing their parent-teen driving agreements.
Other ways to reduce drowsy driving include:
