What is the meaning of a double yellow line?

Answer: B — Passing is not allowed

A double yellow line on the road typically means that passing is not allowed. This is usually done to designate a no-passing zone where visibility is limited. Option A is incorrect because passing is actually not allowed in this scenario. Option C is incorrect because the double yellow line generally separates two lanes of traffic, making driving in either direction dangerous. Lastly, option D is incorrect because stopping and waiting is not applicable to this road marking.
