What safety feature must be checked for proper functioning during a Class D inspection?

During a Class D inspection, checking the functioning of seat belts is crucial for ensuring vehicle safety. Seat belts are one of the primary safety features designed to protect occupants in the event of a collision. They help restrain individuals and reduce the risk of injury by keeping them securely positioned in their seats.

Ensuring seat belts are in proper working order involves checking for signs of wear and tear, such as frayed straps or malfunctioning retractors, which could prevent them from functioning effectively when needed. Additionally, all seat belts in the vehicle must be operable and accessible, as they are a fundamental aspect of automotive safety mandated by law.

While other options, like airbags or headlights, are also safety components, the inspection requirements typically emphasize seat belts due to their direct role in occupant protection during a crash.
