A broken yellow centerline indicates that:

  1. Passing is not permitted.
  2. Passing on the right is permitted when the way ahead is clear.
  3. Passing on the left is permitted when the way ahead is clear. ✓

Answer: C. Passing on the left is permitted when the way ahead is clear.

A broken yellow centerline means passing on the left is permitted when the way ahead is clear.

Why this is the answer

The handbook says a broken yellow line means you may pass if the broken line is next to your driving lane, and you should pass only when it is safe. The question states that permission as passing on the left when the way ahead is clear. The line allows a pass; it does not require one, and safety still controls the decision.

Why the other answers are wrong

Remember it

Broken yellow beside your lane means a pass may be allowed, but only if it is safe.
