What is the key purpose of wearing a seat belt?

The primary purpose of wearing a seat belt is to reduce the likelihood of being ejected from the vehicle during a crash. Seat belts are designed to secure occupants in their seats and prevent them from being thrown forward or out of the vehicle in the event of a collision. This protective function significantly decreases the risk of severe injuries or fatalities that can occur from being ejected, as well as from the impact with the interior of the vehicle or external objects.

Additionally, seat belts work in conjunction with airbags, enhancing overall safety during a crash. By keeping passengers securely positioned, they ensure that safety features in a vehicle, like airbags and crumple zones, function effectively. This emphasizes the critical role of seat belts not just in the event of a crash but in contributing to the overall safety of vehicle occupants.
