What does a broken yellow line signify?

Answer: B — May pass when safe

A broken yellow line on the road signifies that passing is permitted, but only when it is safe to do so. This marking indicates that the lane is open for overtaking another vehicle, allowing drivers to cross the line when they can ensure it is safe to make the maneuver. In practice, when you see a broken yellow line, it typically means that one lane may be moving in the opposite direction, and drivers should check for oncoming traffic before changing lanes or passing. This line serves as a visual cue to promote safety while allowing for some flexibility in traffic flow. Understanding the implications of broken and solid lines is crucial for safe driving, as they communicate important rules for lane usage and passing guidelines.
