Driver's License Test Prep
North Carolina Practice Road Markings

A solid yellow line runs along your side of the lane divider. May you cross it to pass the vehicle ahead?

  1. A.
    Yes, if oncoming traffic is clear for 500 feet.
  2. B.
    Yes, if you can complete the pass within two seconds.
  3. C.
    No, passing is prohibited where a solid yellow line is in your lane. Correct
  4. D.
    Yes, if the vehicle ahead is going well below the posted speed.
The Why

The answer is "No, passing is prohibited where a solid yellow line is in your lane."

The manual lists a solid yellow line in the driver's lane among places where passing is always unsafe and usually illegal. The marking itself is the prohibition, with no sight-distance or speed condition that opens a window to cross it. Choice A pulls the 500-foot figure from the hill-and-curve item on the same no-passing list and treats it as a universal green light to pass, but that distance applies to blind crests and curves, not to a lane whose marking has already said no.

Why the others miss

The traps in the wrong answers

A. Yes, if oncoming traffic is clear for 500 feet.

The 500-foot rule belongs to the hill-and-curve item on the no-passing list; it does not override a solid yellow line in your lane. Lifts the 500-foot sight distance from the hill-and-curve rule and applies it to a yellow-line prohibition the manual states with no sight-distance exception.

B. Yes, if you can complete the pass within two seconds.

The two-second rule is about following distance behind the vehicle ahead, not a time budget that unlocks a pass across a solid yellow line. Confuses the two-second following rule with a passing allowance.

D. Yes, if the vehicle ahead is going well below the posted speed.

A slow vehicle ahead does not override a lane-marking prohibition; the manual says the slow driver should pull over to let traffic pass, not that you may cross a solid yellow line. Carries over the frustrated-driver habit of treating a slowpoke as a free pass, when the responsibility the manual assigns runs the other way: the slow driver yields, the driver behind waits for a legal passing zone.
