What should drivers do when they see a solid yellow line on their side of the road?

When drivers see a solid yellow line on their side of the road, it indicates that passing is not permitted. This marking is used to alert drivers that the lane is not safe for overtaking other vehicles, often because of limited visibility, curves in the road, or the possibility of oncoming traffic. It is a critical safety measure to prevent accidents, as drivers may not have enough space or time to safely complete a passing maneuver when such a line is present.

The presence of a solid yellow line serves as a clear visual cue that reinforces the rules of the road regarding safe driving practices, particularly in areas where visibility and safety could be compromised. Maintaining this regulation helps reduce the risk of collisions and promotes smoother traffic flow.
