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

A solid yellow line adjacent to a broken yellow line indicates that passing is only permitted on the side of the broken line. This road marking serves as a guide to drivers, signaling that if you are in the lane next to the broken line, you may safely pass other vehicles if it is clear and safe to do so. Conversely, if you are in the lane with the solid yellow line, passing is not allowed. This system helps ensure safety on the roads by clearly designating which lanes have passing restrictions and which do not, thereby minimizing confusion for drivers.
