Most effective method of restraint in a traffic crash?

The most effective method of restraint in a traffic crash is the use of seat belts. When worn correctly, seat belts significantly reduce the risk of serious injury or death by keeping occupants securely in their seats, preventing ejection from the vehicle, and helping to distribute crash forces across the stronger parts of the body. Additionally, airbags complement seat belt use by providing an extra layer of protection during a collision. Together, these safety measures are essential for enhancing occupant safety in vehicles.
