A solid yellow line most accurately indicates a no passing zone in many areas.

• A. No passing zone
• B. Passing allowed when safe
• C. Turns are prohibited
• D. Intersection ahead

Answer: (A)

A solid yellow line in the center of a two-lane road signals a no-passing zone. It warns you that crossing that line to pass another vehicle is not safe or allowed because you can’t reliably see oncoming traffic ahead due to visibility limits, curves, hills, or upcoming hazards. This marking is about passing, not turns or intersections, so it doesn’t indicate turning restrictions or an upcoming intersection. If the line were dashed, passing would be allowed when safe; the solid line means you should stay in your lane and not attempt to pass.
