What aspect of the mirrors should be checked during a pre-trip inspection?

During a pre-trip inspection, mirrors are a critical safety feature that must be checked for proper adjustment. Properly adjusted mirrors ensure that the driver has a clear and unobstructed view of the areas to the side and rear of the vehicle, which is essential for safe maneuvering, especially in larger vehicles like those requiring a Class A CDL. If mirrors are not adjusted correctly, it can lead to blind spots, making it difficult for the driver to see other vehicles or obstacles, thereby increasing the risk of accidents.

The focus on adjustment rather than physical characteristics such as cracks or color is crucial because visibility directly impacts safety on the road. Cracked mirrors can hinder visibility, but the primary concern during inspection is ensuring they provide a correct view. Missing mirrors would render the vehicle unsafe under regulations, and while some mirrors may be designed with specific colors, this is not a standard aspect evaluated during a pre-trip inspection.
