What does a broken white line and a solid white center line indicate?

A broken white line next to a solid white center line indicates that traffic on the side of the broken line is permitted to pass, while traffic on the side of the solid line is not allowed to pass. This configuration is commonly used to manage lane changes and overtaking in situations where there may be differing levels of restrictions based on the lane designation. The broken line serves as a visual cue for drivers to signal that passing is permitted when conditions allow, whereas the solid line signifies that the adjacent lane has restrictions, reinforcing the importance of adhering to these lane markings for safety and order on the road.
