North Carolina Practice Passing

A driver behind you sounds a horn to signal a pass. What does the manual require you to do?

  1. A.
    Brake firmly so the passing vehicle can quickly get back in the lane.
  2. B.
    Hold your lane position and let the other driver find a way around.
  3. C.
    Speed up briefly to open a wider gap ahead of the passing vehicle.
  4. D.
    Move to the right edge of the road and do not increase your speed. Correct
The Why

The answer is "Move to the right edge of the road and do not increase your speed."

The manual requires you to move to the right edge of the road when the passing driver blows the horn, and it forbids increasing your speed. Drivers whose instinct is to 'help traffic flow' by opening a gap ahead reach for choice C, which is the exact action the manual singles out and prohibits.

Why the others miss

The traps in the wrong answers

A. Brake firmly so the passing vehicle can quickly get back in the lane.

The manual asks for a move to the right edge, not a change in speed. This answer substitutes a brake reaction, mirroring how a driver yields for an emergency vehicle rather than for a passer.

B. Hold your lane position and let the other driver find a way around.

Doing nothing violates the manual's duty to move to the right edge when the horn sounds. This answer treats the pass as the other driver's problem alone, ignoring the legal share the manual assigns to the vehicle being passed.

C. Speed up briefly to open a wider gap ahead of the passing vehicle.

The manual's specific instruction is to never increase your speed while being passed. This answer reads 'help the other driver' as an invitation to lengthen the pass, when the required help is lateral, not longitudinal.
