North Carolina Practice Speed Limits

The manual says a driver who must go slower than the posted limit should still do what?

  1. A.
    Observe the posted minimum speed limit Correct
  2. B.
    Stay in the leftmost lane for safety
  3. C.
    Match the speed of the slowest visible vehicle
  4. D.
    Turn on hazard lights while under the limit
The Why

The answer is "Observe the posted minimum speed limit"

A driver forced to go slower still must hold at or above the posted minimum speed limit. Drivers who reach for the hazard-flashers habit they use for a disabled vehicle pick D and treat slow-driving as if the flashers were the manual's answer.

Why the others miss

The traps in the wrong answers

B. Stay in the leftmost lane for safety

Slower vehicles belong to the right, and the manual tells drivers to pull to the side when traffic collects behind. This answer reverses the slower-traffic-keep-right rule that governs multi-lane driving.

C. Match the speed of the slowest visible vehicle

The manual keys slow driving to the posted minimum, not to whatever slower vehicle is on the road. This answer substitutes a look-around instinct for the fixed reference point printed on the minimum-speed sign.

D. Turn on hazard lights while under the limit

The manual does not treat driving below the posted limit as a hazard-flashers situation. This answer carries the disabled-vehicle habit of flashers-on into slow-driving, which the manual does not prescribe.
