The use of seat belts is critically important for passenger safety, particularly during a sudden stop or collision. When properly worn, seat belts are designed to secure occupants in their seats and significantly reduce the risk of being ejected from the vehicle. In the event of a crash, the force of impact can propel an unrestrained occupant forward at high velocity, potentially leading to serious injuries or even fatalities. A seat belt keeps the person in place, thereby protecting them from being thrown out of the vehicle and hitting objects like the windshield.

While seat belts also play a role in preventing injury to rear-seat passengers, minimizing damage to the vehicle, and ensuring the ability to exit safely, their primary function is to restrain occupants during sudden movements, making the prevention of ejection the most critical outcome in such situations.
