An estimated 145 million U.S. adults—61% of the adult population—have driven while drowsy at least once, and nearly 35 million do so monthly, according to data highlighted by the National Sleep Foundation. The findings underscore a persistent public health risk: four in ten adults, or about 108 million people, fail to recognize the basic warning signs of drowsy driving, creating a critical knowledge gap that can have deadly consequences. A fall-asleep crash can kill or injure in an instant, making it essential for drivers to prioritize sleep and recognize when they are not fit to drive.
The National Sleep Foundation produces Drowsy Driving Prevention Week®, an annual campaign that educates the public about the importance of sleep for safe driving and encourages drivers to Sleep First. Drive Alert.® The campaign emphasizes that preventing drowsy driving starts with choices made before getting behind the wheel, such as prioritizing adequate sleep. Basic warning signs include frequent blinking, nodding off, difficulty keeping eyes open, and drifting out of a lane. Recognizing these signals early is crucial because drowsiness slows reaction times and increases crash risk. Drivers who notice any of these signs should pull over to a safe place and take a break.
Technology may offer additional support. The automotive industry continues to develop driver-alertness systems designed to detect signs of sleepiness and fatigue and help prevent crashes. Public acceptance appears strong: an estimated 91 million U.S. adult drivers support requirements for alertness technology in all new vehicles, and a similar number favor including sleep and drowsy-driving education in driver licensing. However, awareness and adoption lag—while 58% of adults are familiar with driver-alertness monitoring, only 31% have ever used it. That gap represents a significant opportunity to increase understanding and access. Privacy concerns remain a barrier, with 62% of adults worried that data collected by such systems could be misused. Combining advanced technology with public education and data privacy protections can help build trust and make roads safer for everyone.
The implications are clear: as drowsy driving remains widespread and underrecognized, efforts must focus on both personal responsibility and systemic solutions. The National Sleep Foundation, an independent nonprofit founded in 1990, continues to promote sleep health through expert recommendations, consensus guidelines, and easy-to-use tools.

When in doubt, the safest decision is not to drive—reschedule trips, delay departure until alert, or arrange for a trusted friend, taxi, or rideshare to drive instead.
