What does a solid line next to a broken line mean?

The presence of a solid line next to a broken line signifies that passing is not allowed from the side with the solid line. This marking is crucial for ensuring safety on the road, as it indicates that the lane next to the solid line may have hazards that make passing risky. Conversely, vehicles traveling in the direction where the broken line is present are permitted to pass when it is safe to do so. This distinction helps drivers understand their responsibilities and enhance roadway safety by preventing dangerous maneuvers in areas where visibility or road conditions may not permit safe passing.
