What is the primary purpose of a seatbelt?

The primary purpose of a seatbelt is to secure passengers and reduce the risk of injury in a crash. Seatbelts are designed to hold occupants in place during sudden stops or collisions, effectively minimizing the likelihood of ejection from the vehicle and providing protection against injury caused by the forces of a crash. When worn properly, they distribute the energy exerted on the body during an accident across stronger parts of the body, such as the chest and pelvis, which can significantly decrease the risk of serious injuries and fatalities.

In contrast, while comfort may be a consideration during driving, it does not capture the critical safety role that seatbelts play. Similarly, seatbelts do not directly prevent distractions; their main function is related to safety and protection during a crash. Additionally, while seatbelts help keep passengers seated securely, this is a secondary benefit; the primary function remains their role in enhancing safety during driving scenarios.
