What is the primary purpose of a seatbelt?

The primary purpose of a seatbelt is to secure occupants during a collision. Seatbelts are designed to restrain the body's movement in the event of an accident, significantly reducing the risk of injury or death. By keeping passengers in their seats, seatbelts help to prevent occupants from being thrown around inside the vehicle or ejected from it, which can lead to severe injuries.

This safety feature plays a critical role in protecting passengers by distributing the forces of a crash across stronger parts of the body, thus minimizing the impact on any one area. Seatbelts are a fundamental aspect of vehicle safety systems, and their proper use is one of the most effective ways to enhance the overall safety of occupants in a vehicle during a crash.
