North Carolina Practice Road Markings

Between opposing lanes, a double-solid yellow line means what about passing?

  1. A.
    Slower drivers must move to the shoulder.
  2. B.
    Trucks may pass but cars may not.
  3. C.
    Passing is fine when both lanes are dry.
  4. D.
    Passing is prohibited from both sides. Correct
The Why

The answer is "Passing is prohibited from both sides."

The double-solid yellow line sits on the manual's list of places where passing is always unsafe and usually illegal, so neither direction may pass. Choice C reaches for a rule of thumb that dry pavement equals safe passing; dry conditions govern speed and following distance, but they do not override the double yellow line.

Why the others miss

The traps in the wrong answers

A. Slower drivers must move to the shoulder.

The rule governs passing, not what slower traffic must do with the shoulder. This answer confuses the double yellow line with a slower-traffic-keep-right rule from a different section.

B. Trucks may pass but cars may not.

The manual sets no truck exception for double-solid yellow lines. This answer applies vehicle-class thinking to a marking that treats every driver the same.

C. Passing is fine when both lanes are dry.

Pavement conditions do not change what a double yellow line prohibits. This answer trades a marking rule for a road-condition rule of thumb about dry surfaces.
