What does it mean if there is a solid yellow line next to a broken yellow line?

When there is a solid yellow line next to a broken yellow line, it indicates that passing is permitted only from the side where the broken line is present. This road marking is designed to regulate traffic and enhance safety by signaling to drivers which direction has the legal allowance to overtake vehicles.

In this configuration, the solid line serves as a barrier to prevent passing from that side, typically indicating that it is either unsafe to do so because of visibility issues or other hazards, such as an oncoming traffic lane. Therefore, a driver on the side with the broken line can legally pass, while a driver on the side with the solid line must remain in their lane. This clear demarcation helps prevent potential collisions and allows drivers to make safe decisions when navigating roads.
