What action can double your chances of surviving a crash?

Wearing safety belts significantly increases the chances of surviving a crash because they are designed to keep occupants securely in their seats and minimize movement during a collision. Seat belts prevent ejection from the vehicle and reduce the risk of serious injuries by distributing the force of a crash across the stronger parts of the body. They are proven safety devices that can save lives; in fact, studies indicate that wearing a seat belt can reduce the risk of fatal injury by approximately 45% for front-seat passengers in passenger vehicles.

While the other options also contribute to safe driving and can reduce the risk of accidents or enhance safety, they do not have the same life-saving efficacy as seat belts during a crash. Using headlights improves visibility, driving at reduced speeds lowers the severity of a crash, and avoiding distractions helps prevent accidents in the first place, but none of these actions can double survival chances in a crash like wearing a safety belt can.
