What does a solid double yellow line indicate?

• A. No passing; stay in your lane and do not cross the lines to pass
• B. Passing allowed when safe
• C. No stopping in that area
• D. You may pass after yielding

Answer: (A)

Solid double yellow lines mean no passing in either direction. On a two-way road with these markings, you must stay in your lane and must not cross the lines to pass another vehicle because visibility or road conditions make passing dangerous. You only cross lines in specific turning situations (like turning left into a driveway or private road when permitted), not to pass. The other ideas describe passing where it’s allowed or stopping rules that don’t apply to this marking, so they don’t fit.
