Convex mirrors, sometimes called "spot" mirrors, are found on some big trucks. What should you know about them?

Correct answer: They show objects as smaller and more distant than they really are.

Answer options

  1. AThey are illegal in most states.
  2. BThey show objects as smaller and more distant than they really are. Correct
  3. CThey can be checked less often than flat mirrors because they cover more area.

Why

A convex mirror gives a wider field of view but shrinks the image, so other vehicles seem smaller and farther off than they truly are. Glance at these mirrors often, and judge distances knowing that what you see is nearer than it looks.
