Which line marks traffic moving in opposite directions?

• A. Yellow lines separate traffic moving in opposite directions.
• B. White lines separate traffic moving in opposite directions.
• C. Solid white lines indicate opposite directions.
• D. Double white lines indicate opposite directions.

Answer: (A)

The color used to divide opposing traffic flows is yellow. On two-way streets, the centerline is painted yellow to show that traffic on the other side is coming toward you, helping you recognize the boundary between opposite directions and decide when it’s safe to pass (usually only when your side of the line is dashed). In contrast, white lines separate lanes moving in the same direction, guiding lane changes and staying in your lane. Solid lines generally mean you should not cross, while dashed lines mean crossing is allowed when safe. So the yellow centerline is what marks traffic moving in opposite directions.
