What is the purpose of a seatbelt?

Answer: B — To reduce the risk of injury or death in a crash

The primary purpose of a seatbelt is to reduce the risk of injury or death in a crash. When a vehicle is involved in a collision, the force of the impact can cause unrestrained occupants to be thrown around inside the vehicle or ejected from it, significantly increasing the likelihood of severe injuries. Seatbelts are designed to hold passengers securely in their seats, preventing them from being propelled forward or out of the vehicle, which helps to mitigate the impact of the crash on the body. By restraining occupants, seatbelts also help to distribute the forces of a crash across stronger parts of the body and work in conjunction with other safety features in the vehicle, such as airbags. As such, wearing a seatbelt plays a crucial role in enhancing vehicle safety and is one of the most effective ways to safeguard lives on the road.
