What does a solid double yellow line indicate in the center of the road?

• A. Passing allowed with caution.
• B. No passing by traffic in either direction.
• C. Only passing with the left turn lane.
• D. You must always pass on the left.

Answer: (B)

Two solid yellow lines in the center indicate a no-passing zone for traffic in both directions. They’re placed where visibility is limited or hazards exist, making it unsafe to overtake another vehicle. Stay in your lane and don’t pass until you reach a section marked with a dashed line or a designated passing zone. This marking is about preventing head-on collisions, not about special turning rules, which is why the other ideas about passing or turning left are not correct in this context.
