Should driving while dangerously drowsy be illegal when it causes serious injury or death?
A National Sleep Foundation report estimates 145 million American adults have driven drowsy, with more than 60% of American drivers admitting to it. The findings, published by HealthDay on November 4, 2026, apply to drivers across the United States.
Why it matters
Drowsy driving is treated as a hidden risk because drivers often fail to notice when they are too tired to drive safely. The report's findings suggest the problem is widespread enough to shape how people think about sleep and road safety.
The figures come from a National Sleep Foundation report that cites crash data on drowsy driving's share of fatal crashes. The report's survey methodology and sample size were not available in the source material.
The players
National Sleep Foundation
A U.S. nonprofit focused on sleep health education, research, and public awareness campaigns about the role of sleep in overall well-being.
HealthDay
A health news service that reports on medical research and public health findings for consumers and clinicians.
The details
Drowsiness impairs attention, slows reaction time, and makes it harder to stay in a lane, which is why it can be as dangerous as impaired driving. Common warning signs include frequent blinking, head-nodding, and drifting out of a lane. Because many drivers fail to recognize these signs, they may keep driving when they should stop.

Health Landscape
Drowsy driving has long been overshadowed by alcohol and distraction in public safety messaging, even though sleep loss impairs driving in similar ways. These findings add population-level data to a public health conversation that has focused mainly on the risks of insufficient sleep.
If you regularly drive when tired, it is worth recognizing the warning signs of drowsiness such as frequent blinking, head-nodding, and drifting out of your lane. The recommended seven to nine hours of nightly sleep for adults is a practical benchmark to check your own habits, and a conversation with your doctor can help if sleep problems persist.
The takeaway
Drowsy driving is a common risk that many drivers do not recognize in themselves. Aim for seven to nine hours of sleep per night, and treat warning signs like frequent blinking or drifting out of your lane as a reason to stop and rest.
