North Carolina Practice Road Markings

On a three-lane highway, where does the manual say you may pass?

  1. A.
    In the center lane, where marked for your direction. Correct
  2. B.
    Only in the lane closest to the shoulder.
  3. C.
    In the left lane, as on a divided highway.
  4. D.
    In any lane, as long as the pavement is clear ahead.
The Why

The answer is "In the center lane, where marked for your direction."

On a three-lane highway, passing is limited to the center lane, and only where that lane is marked for passing in your direction. The manual states one exception: when the vehicle in the center lane is making a left turn, you may pass it. Choice C tempts drivers who carry the interstate habit of staying far left to pass onto an undivided three-lane road, where the center lane does that job instead.

Why the others miss

The traps in the wrong answers

B. Only in the lane closest to the shoulder.

The shoulder-side lane is not the permitted passing lane: the manual names the center lane marked for passing in your direction, with a stated exception when the center-lane vehicle is turning left. Reads the pass-on-the-right exception that applies on highways with two lanes in each direction as if it set the rule for a three-lane highway.

C. In the left lane, as on a divided highway.

A three-lane highway is not a divided road: the manual names the center lane, not the left lane, as the passing lane, with the stated left-turn exception. Carries the interstate habit of staying far left to pass onto an undivided three-lane road, where the leftmost lane is not the one marked for passing.

D. In any lane, as long as the pavement is clear ahead.

A clear view ahead is one requirement for safe passing, not the whole permission: the manual still restricts you to the center lane marked for passing in your direction, except when the center-lane vehicle is making a left turn. Carries the two-lane country-road rule of thumb that a clear oncoming lane is permission enough, and skips the extra lane-marking requirement the manual lays on three-lane roads.
