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

A broken yellow line next to a solid yellow line indicates that traffic is traveling in opposite directions. The solid line signifies that passing is not allowed for the lane next to it, while the broken line allows vehicles in the lane with the broken line to pass other vehicles when it is safe to do so. This marking effectively communicates the directionality of the lanes—one side is restricted in terms of passing, while the other allows for some flexibility, enhancing road safety by clearly delineating lanes for opposing traffic. Understanding this marking helps drivers make informed decisions about overtaking other vehicles safely.
