What does a solid yellow line next to a broken line mean?

Answer: B — Vehicles next to the broken line may pass

A solid yellow line next to a broken line indicates that vehicles adjacent to the broken line are allowed to pass. This configuration means that if you are on the side of the road where the broken line is present (indicating a lane that is open for passing), you have the option to overtake another vehicle. However, it also emphasizes that drivers on the side of the solid line must not pass, as that lane is intended for vehicles traveling in the opposite direction. In this scenario, a broken line generally signifies that passing is permitted, while the solid line indicates that passing is not allowed from that direction. Thus, this marking layout is crucial for communicating the rules regarding lane changes and overtaking, ensuring a smoother and safer flow of traffic. This understanding helps drivers make informed decisions on whether it is safe to pass based on their position relative to the lines.
