What do one solid line and one broken line indicate regarding passing?

One solid line and one broken line on the roadway indicate that passing is not allowed in the lane with the solid line. The solid line signifies that the driver should not cross it to pass another vehicle, indicating a restriction. Conversely, the broken line allows for passing where it is safe to do so in the lane with the broken line. This arrangement provides clear guidance to drivers about when and where it is permissible to pass, promoting safety on the road by discouraging overtaking in potentially hazardous areas. The presence of the solid line serves as a visual warning that passing may be dangerous in that section of the roadway.
