which mirror is used in vehicles for rear view

Vehicles use a flat (plane) mirror as the primary rearview mirror mounted inside on the windshield to provide a clear, undistorted view of traffic directly behind through the rear window.

This differs from the convex mirrors on the side doors (wing mirrors), which offer a wider field of view but make objects appear smaller and farther away—often marked with warnings like "Objects in mirror are closer than they appear."

Mirror Types Explained

• Plane Rearview Mirror : Delivers true-to-size images for accurate distance judgment; adjustable for day/night glare reduction.

• Convex Side Mirrors : Expand visibility to reduce blind spots, ideal for lane changes, though images are diminished.

• Exceptions in Trucks/Buses : Larger vehicles may use convex rearview mirrors due to obstructed rear windows.

Why This Setup?

Plane mirrors prioritize precision for the central rear view, while convex ones handle peripheral angles safely. This combination evolved from early 1900s designs into mandatory safety features by the 1960s.

Forum Buzz & Myths

Online discussions, like recent Reddit threads, sometimes confuse interior mirrors with reversing aids, but experts clarify the standard is plane for interiors.

TL;DR : Flat plane mirrors for vehicle rearview; convex for sides.
