What is the purpose of a seat belt?

The primary purpose of a seat belt is to keep passengers secure during a vehicle's operation. Seat belts are designed to restrain occupants in their seats and reduce the risk of injury or death in the event of a collision or sudden stop. When worn properly, seat belts prevent passengers from being thrown from the vehicle and help to distribute the forces of a crash across stronger parts of the body, thereby minimizing the likelihood of serious injuries. This safety feature is crucial in protecting both the driver and passengers while on the road.
