Which equipment must be checked for clearance during the safety inspection?

During the safety inspection, checking for clearance involves ensuring that any additional equipment on the vehicle does not interfere with its operation or pose a hazard. Mud flaps are crucial for this assessment because they help prevent debris from being thrown by the tires, which can affect visibility and safety for other drivers. They need to be properly positioned and sufficiently clear from the ground and surrounding components to avoid obstructions.

While window cleanliness, dashboard instruments, and headlights are also important safety factors, they do not specifically pertain to the issue of clearance that mud flaps address. Windows should be clean for visibility, dashboard instruments must function correctly for operational safety, and headlights need to be functional for nighttime driving, but none of these items directly involve checking physical clearance from the ground or surrounding elements on the vehicle during the inspection process.
