What does a solid yellow line on your side of the center of a two-way road mean?

Yellow lines separate traffic moving in opposite directions on a two-way road. A solid yellow line on your side of the center means you may not cross it to pass — passing is prohibited there. A broken (dashed) yellow line on your side means passing is permitted when it is safe. Where there are two lines, a solid line paired with a broken line means passing is allowed only for the side with the broken line. Double solid yellow lines prohibit passing in both directions. Understanding yellow center-line markings — solid means no passing, broken means passing allowed when safe — is essential pavement-marking knowledge.
