Which of the following is NOT a common inspection item?

Interior cleanliness is not considered a common inspection item during a standard vehicle inspection. The primary focus of vehicle inspections is to ensure the vehicle is safe for operation on public roads. This typically involves checking items that directly impact the vehicle's performance, safety, and compliance with regulations.

Steering systems, lights functionality, and tire integrity are critical components that are routinely inspected as they have a direct effect on driving safety. For instance, a well-functioning steering system is essential for vehicle control, while properly functioning lights are crucial for visibility and signaling to other drivers. Tire integrity is equally important, as worn or damaged tires can significantly affect traction and stopping distances.

In contrast, while maintaining clean interiors is certainly beneficial for comfort and aesthetics, it does not directly influence the mechanical safety of the vehicle and thus falls outside the typical criteria for inspection.
