Which mirror gives the widest view of the area along the side of the trailer during backing, and what is its drawback?
- A.The convex mirror shows the widest area, but objects appear smaller and farther away than they really are
- B.The flat mirror shows the widest area with no distortion
- C.The inside rearview mirror shows the trailer sides
- D.Convex mirrors double the size of objects
Correct answer
A. The convex mirror shows the widest area, but objects appear smaller and farther away than they really are
Why
Convex mirrors trade accuracy for coverage: you see more of the side and rear, but distance judgment suffers. Skilled backers cross-check convex and flat mirrors and still get out and look when the margin is tight.
