How does a seat belt increase your chances of survival?

A seat belt increases your chances of survival during a car accident by restraining the occupant's body, preventing ejection from the vehicle and reducing the risk of severe injuries. It helps to distribute the forces of a collision more evenly across stronger parts of the body, such as the pelvis and ribcage. Additionally, by keeping passengers in their designated seating positions, seat belts allow airbags to function effectively, further enhancing protection. Overall, wearing a seat belt significantly reduces the likelihood of fatal injuries in crashes.
