In terms of safety equipment, what is the primary function of working safety belts?

The primary function of working safety belts is to keep passengers stationary during sudden stops. In the event of a collision or an abrupt stop, safety belts are designed to secure occupants in their seats, effectively preventing them from being thrown forward or ejected from the vehicle. This restraint system significantly reduces the risk of injury by keeping passengers in a protective position within the vehicle's cabin and allowing the vehicle's safety features, such as airbags, to function as intended.

While other options present functions that may not be accurate or relevant to the primary purpose of safety belts, understanding the correct role of safety belts emphasizes their importance in enhancing overall vehicle safety. It reinforces the idea that the design and use of safety equipment are critical for preventing injuries in the event of an accident.
