When are seat belts required to be worn by all passengers in a vehicle?

Answer: C — By all passengers at all times

Seat belts are required to be worn by all passengers in a vehicle at all times to enhance safety and reduce the risk of injury in the event of an accident. The law aims to ensure that everyone in the vehicle, regardless of their seat position, is protected. This requirement is based on safety statistics that show how effective seat belts are in preventing severe injuries and fatalities during collisions. Wearing a seat belt not only protects the individual passenger but also improves the overall safety of the vehicle. This reflects a broader public safety initiative, emphasizing the importance of responsible driving practices. By mandating that all passengers buckle up at all times, it fosters a culture of safety in vehicles, contributing to lower accident-related injuries and deaths. Other options suggest limited scenarios for wearing seat belts, which do not align with the comprehensive requirement designed to maximize safety for everyone in the vehicle.
