What is the legal meaning of a broken yellow line painted in the center of a two-lane roadway?
The answer
Answer: D. A broken yellow line painted in the roadway center separates traffic lanes traveling in opposite directions and permits passing when the oncoming lane is clear. Before passing, ensure you have sufficient distance to complete the maneuver and return to your lane safely. Never attempt to pass when approaching curves, hills, or intersections where forward visibility is restricted.
