What is required for a vehicle with obstructed rear view due to cargo?

When a vehicle has an obstructed rear view due to cargo, it is crucial to ensure that the driver has adequate visibility to safely operate the vehicle. The requirement for two outside mirrors serves this purpose effectively.

Having two outside mirrors, typically a driver's side mirror and a passenger's side mirror, compensates for the blocked rear view by providing a wider field of vision. This setup helps the driver be aware of other vehicles and obstacles behind and alongside the vehicle, thus enhancing safety while driving.

In contrast, a single rearview mirror alone might not provide sufficient visibility, especially in larger vehicles where the rear view can be significantly obstructed. A backup camera, while useful, is often not a substitute for proper outside mirrors and may not be mandatory in all situations. Similarly, while a rear window being present is important for visibility, it does not address situations where cargo obstructs that view. Thus, the requirement for two outside mirrors specifically addresses the safety concern of reduced rear visibility caused by cargo obstruction.
