What does a broken yellow centerline generally allow?

Correct answer: B – Crossing the centerline to pass when legal and safe
A broken yellow centerline separates traffic moving in opposite directions and may be crossed to overtake or pass. The Montana manual emphasizes that the driver must still judge whether enough clear space is available. A broken line permits consideration of a pass; it does not guarantee that passing conditions are safe.
