What is the purpose of a seatbelt?

The primary purpose of a seatbelt is to reduce the risk of injury during a collision. By securely holding passengers in their seats, seatbelts help prevent occupants from being thrown forward or ejected from the vehicle in the event of a crash. This restraint system significantly lowers the chances of serious injuries such as head trauma or spinal injuries, which can occur when a vehicle comes to an abrupt stop. Seatbelts are essential safety devices that work in conjunction with other safety features of the vehicle, such as airbags, to provide comprehensive protection.

While comfort, proper seating position, and reducing distractions are important factors in vehicle safety and driving experience, they do not represent the primary function of a seatbelt. The core function is indeed about enhancing safety during an unexpected incident on the road.
