What is necessary for a vehicle to pass inspection concerning mirrors?

For a vehicle to pass inspection, it is essential that if the rear view through the window is obstructed, it must have two functioning outside mirrors. This requirement ensures that the driver has adequate visibility of the area behind the vehicle, which is critical for safe driving and maneuvering. The presence of multiple mirrors helps to minimize blind spots and allows the driver to see approaching vehicles or obstacles that might not be visible through the rear window.

Having one rearview mirror is not sufficient if the view is obstructed, as it does not provide the necessary range of visibility needed for safe operation. While some vehicles may have backup cameras, they are not mandatory for passing inspection, and the main focus remains on the physical mirrors that assist in providing a clear view. Therefore, having two functioning outside mirrors serves as a vital requirement for ensuring safety on the road.
