What is the condition for the rearview mirror during inspection?

During the Pennsylvania State Auto Inspection, the rearview mirror must hold its adjustment and be free of cracks to ensure safe driving conditions. A properly functioning rearview mirror allows the driver to maintain a clear line of sight to the rear of the vehicle, which is essential for safe maneuvering, especially when changing lanes or reversing. If the mirror cannot hold its position, it may shift during driving, leading to reduced visibility. Additionally, any cracks in the mirror can obstruct vision, create blind spots, or even cause injury in the event of an accident. Therefore, this condition is critically important for vehicle safety during inspections.

The other options do not align with the specific requirements set forth for rearview mirrors during inspections. While tinting and size may have aesthetic or functional implications, the key focus during inspections is the mirror's structural integrity and ability to provide clear viewing without obstruction. Autonomy is not relevant to the function of typical rearview mirrors under inspection protocols either.
