Fatality risks in accidents are reduced by what percentage when occupants wear seatbelts?

Answer: C — 45%

Wearing seatbelts significantly enhances the safety of vehicle occupants, and research indicates that the risk of fatality in accidents is reduced by approximately 45% when occupants are buckled up. This statistic stems from extensive studies conducted by traffic safety organizations, which demonstrate that seatbelts play a critical role in preventing ejection from the vehicle and reducing the severity of injuries during collisions. In supporting this answer, it is important to note that seatbelts serve to restrain passengers during an accident, keeping them in their designated seats and allowing the vehicle's safety features, such as airbags, to work effectively. With a nearly 50% reduction in fatality risk, the data underscores the vital role that seatbelts play in enhancing occupant safety. This is why the choice reflecting a 45% reduction accurately captures the importance of seatbelt use in driving safety.
