What does a solid yellow line on a roadway indicate?

A solid yellow line on a roadway serves as a clear visual cue that indicates passing is not allowed in the lane where the line is present. This marking is crucial for maintaining safety, as it signifies to drivers that the road conditions or the layout may not be safe for overtaking another vehicle. Areas where a solid yellow line is in place often involve curves, intersections, or other situations where visibility is limited, thus making passing hazardous.

It is important for drivers to adhere to this indication to prevent accidents and ensure smooth traffic flow. The other options imply passing rights, speed regulations, or pedestrian considerations, none of which align with the purpose of a solid yellow line, which is specifically focused on prohibiting passing to enhance safety on the roadway.
