North Carolina Practice Defensive Driving

Beyond the mirror blind spots at the rear corners, the manual names other things that create blind spots. Which of these is on its list?

  1. A.
    Glare, dirty windshields, and bushes near an intersection Correct
  2. B.
    Side mirrors fogged by rain or steam
  3. C.
    Headrests set to their highest position
  4. D.
    Rearview mirrors tilted downward too far
The Why

The answer is "Glare, dirty windshields, and bushes near an intersection"

The manual names glaring lights, dirty windshields, vehicles parked too closely to an intersection, and bushes or buildings as additional sources of blind spots. Drivers who picture a blind spot only as a weather problem on glass reach for choice B, because fogged mirrors feel like the same kind of visibility issue, but the manual's examples here are the glare and obstructions listed in this passage, not condensation on a mirror.

Why the others miss

The traps in the wrong answers

B. Side mirrors fogged by rain or steam

Fogged mirrors lower visibility, but they are not among the additional sources of blind spots the manual lists in this passage. Confuses a weather problem on the mirror glass with the glare and obstructions the manual actually names.

C. Headrests set to their highest position

Headrest height is a seat adjustment, not one of the additional sources of blind spots the manual lists. Treats any in-cabin setup issue as a blind-spot source rather than checking it against the examples this passage names.

D. Rearview mirrors tilted downward too far

A badly aimed mirror shortens what you can see in it, but mirror aim is not among the additional sources of blind spots the manual lists. Reaches for a mirror-adjustment problem the Mirrors section covers instead of the examples the Scanning passage actually names.
