The National Highway Traffic Safety Administration (NHTSA) estimates that every year there are 100,000 drowsy driving crashes reported to police costing $12.5 billion.
Most drowsy driving crashes happen at predictable times. We are most likely to feel fatigued, and our risk of being involved in a drowsy driving-related crash increases between 1 p.m. and 4 p.m. and 2 a.m. and 6 a.m.
Fifty-one percent of adults reported that they have driven while drowsy, and 17 percent reported falling asleep at the wheel in the past year. Working late night shifts, taking care of young children, or managing hectic schedules can all be risk factors for drowsy driving.
