What must the mirrors pass as part of the inspection checklist?

Answer: C — Must be clean

The requirement that mirrors must be clean is critical for safety during driving. Clean mirrors ensure that the driver has an unobstructed and clear view of the surroundings, including other vehicles, pedestrians, and obstacles. This visibility is essential for making safe maneuvers, changing lanes, and keeping aware of any potential hazards. In a pre-trip inspection, the driver should check mirrors for dirt, fog, cracks, or any obstructions that could impair visibility. Clean mirrors contribute to reducing the risk of accidents and enhance overall driving safety.
