How many accidents a year are caused by drowsy driving?

Drowsy driving is a significant contributor to traffic accidents, with estimates suggesting that it causes around 100,000 crashes annually in the United States alone. These accidents result in approximately 71,000 injuries and 6,000 fatalities each year. The true numbers may be higher, as drowsiness is often underreported in crash investigations. Efforts to raise awareness and promote education about the dangers of drowsy driving are ongoing.
