What is the purpose of checking the mirrors during a pre-trip?

The purpose of checking the mirrors during a pre-trip inspection is primarily to ensure they are clean and properly adjusted. Clean mirrors are essential for maintaining visibility and safety while driving, as dirt or debris can obstruct the driver's view of surrounding vehicles and obstacles. Proper adjustment is equally important because it ensures that the driver has the best possible viewing angles, allowing for quick and accurate assessments of the traffic environment.

Clear and correctly aligned mirrors help reduce blind spots and promote safe maneuvers such as lane changes and turns, essential for both the driver and other road users. This step is a critical part of a pre-trip inspection to ensure the vehicle is safe and roadworthy before operating it.
