When a broken white line and a solid white center line appear together, which side is permitted to pass?

When a broken white line and a solid white center line are present together, the broken white line indicates that lane changes are allowed for the traffic on that side. Therefore, vehicles traveling on the side with the broken white line may legally pass or change lanes. Conversely, the presence of the solid white line reinforces that traffic on that side is not permitted to pass. This traffic must remain in its lane and is restricted from crossing the line to overtake other vehicles. Understanding this allows drivers to recognize and comply with the rules regarding lane usage and passing, contributing to overall road safety.
