What is the purpose of seat belts?

Answer: C — To prevent injury in the event of a crash

The primary purpose of seat belts is to prevent injury in the event of a crash. Seat belts are designed to restrain occupants and hold them in place during sudden stops or collisions. By keeping passengers securely positioned in their seats, seat belts reduce the likelihood of being thrown from the vehicle or striking the interior surfaces during an accident. This protective measure significantly decreases the risk of serious injuries or fatalities, which is why wearing a seat belt is a fundamental safety requirement when operating or riding in a vehicle. While comfort, fuel efficiency, and adherence to design standards might have some relevance in a different context, they do not reflect the critical life-saving function of seat belts during a crash scenario. The effectiveness of seat belts in enhancing safety is well-documented and is a key reason for their mandatory use in many regions, including Alberta.
