For safe vehicle operation, what should the rear view mirrors provide?

The rear view mirrors should provide a field of vision to help monitor traffic behind, which is critical for safe vehicle operation. These mirrors allow drivers to see what is happening behind and to the sides of their vehicles, enabling them to make informed decisions when changing lanes or merging. By having a comprehensive view of the area around the vehicle, drivers can maintain awareness of other road users and avoid potential collisions.

This wider field of vision is essential for safe driving, especially in situations like lane changes or when approaching intersections. Properly adjusted mirrors enhance visibility and reduce blind spots, thereby increasing overall safety on the road.
