What is the purpose of a seatbelt?

The primary purpose of a seatbelt is to reduce the risk of injury in a crash. When a vehicle is involved in a collision, the forces exerted can be extremely high, and without a seatbelt, occupants can be thrown against the interior of the vehicle or ejected entirely. Seatbelts are designed to restrain occupants and keep them securely in their seats, significantly decreasing the likelihood of severe injuries or fatalities.

In addition, seatbelts work by spreading the force of a crash across the stronger parts of the body, such as the pelvis and rib cage, which enhances safety. This protective mechanism is especially crucial at high speeds, where the potential for harm increases dramatically. The effectiveness of seatbelts in preventing injuries has been supported by extensive research and data, making their use a vital aspect of road safety.
