What is the meaning of a solid double yellow line in the center of the road?

• A. You may pass on the left.
• B. No passing by traffic in either direction.
• C. Passing allowed with caution.
• D. You must stop when approaching.

Answer: (B)

A solid double yellow line means no passing in either direction. These lines indicate a no-passing zone because visibility is limited or there are hazards ahead, so staying in your lane is required for safety. You should not cross these lines to pass another vehicle, even if you think you’re going faster or have more room. You can, however, turn left across the lines to enter or leave a driveway or street when it’s safe, but passing across them is not allowed. The other ideas—passing on the left, passing with caution, or stopping—don’t fit because the rule here is a strict prohibition on passing in both directions.
