What is the primary reason for wearing a seatbelt?

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

Wearing a seatbelt is primarily aimed at reducing the risk of injury in the event of a crash. Seatbelts are designed to secure occupants in place, preventing them from being thrown forward or ejected from the vehicle during a collision. This is vital as the force of a crash can result in severe injuries or fatalities, and seatbelts significantly lower the likelihood of such outcomes. By keeping the body properly restrained, seatbelts help protect vital organs and maintain a safer environment for all vehicle occupants, making them an essential safety feature in automobiles. While other factors may contribute to seatbelt use, such as compliance with laws or comfort while driving, the foremost reason remains the protective advantage they provide during car accidents.
