What is an essential feature of the vehicle's mirrors during an inspection?

During an inspection, the proper adjustment of the vehicle's mirrors is critical for ensuring safety and visibility while driving. Properly adjusted mirrors allow the driver to have a clearer view of the surroundings, which includes blind spots, other vehicles, and any obstacles. This adjustment helps prevent accidents by expanding the driver's field of vision and ensuring that they can monitor their environment effectively.

While features such as being electric, having a heating element, or being tinted may add convenience or comfort, they are not essential to the fundamental purpose of the mirrors in promoting safe vehicle operation. The primary concern during an inspection is functionality and the ability to provide adequate visibility, which is achieved through proper adjustment. This makes it a key focus during the inspection process.
