How does buckling up impact the risk of injury in a vehicle collision?

Answer: C — It decreases the risk of internal ejection injuries

Buckling up significantly decreases the risk of internal ejection injuries during a vehicle collision. Seat belts are designed to restrain occupants in their seats, reducing the likelihood of being thrown from the vehicle upon impact. When an individual is ejected from a vehicle, the risk of severe injury or fatality increases dramatically due to the potential for hitting the ground or other objects. By keeping individuals securely in their seats, seat belts help to keep them within the protective confines of the vehicle, which is specifically designed to absorb and minimize the forces experienced during a crash. In addition to internal ejection injuries, seat belts offer a range of protective benefits against other types of injuries as well, making them a crucial safety feature in any vehicle.
