What is the required condition of crossover mirrors during an inspection?

The required condition of crossover mirrors during an inspection must be that they are secure, not damaged, and have no loose or missing fittings or parts. This condition ensures that the mirrors provide a clear and unobstructed view for the driver, which is crucial for safety while operating the vehicle. Properly secured mirrors that are undamaged also enhance the driver's ability to monitor blind spots and surrounding traffic, reducing the risk of accidents.

Maintaining mirrors in a secure condition without damage or missing components is vital for effective communication between vehicles on the road. If the mirrors are loose, broken, or hanging, as suggested in some other options, they would not provide effective visibility and could pose risks both to the driver and to others on the road. Therefore, the correct choice emphasizes the significance of a well-maintained set of crossover mirrors in ensuring overall vehicle safety.
