Seat belts are a proven safeguard, but their impact depends on the situation. This page explains what happens to unbelted passengers and drivers in fatal crashes, including the heightened ejection risk and how belt use changes outcomes in frontal collisions. You’ll also see belt-use trends in the US, how enforcement and state laws differ, and how medical and economic costs connect to restraint behavior.
Key Takeaways

- Passenger vehicles saw 22,935 occupant deaths in 2021, half unbelted.
- Unrestrained occupants were 30 times more likely to be ejected fatally.
- Seat belts saved $244 billion in medical costs from 1975-2016.
