What does a solid yellow line mean?

A solid yellow line indicates that no passing is allowed in that area. This marking is used to signal drivers that the road conditions or visibility may be unsafe for passing, which is crucial for maintaining safety on the road. The solid yellow line serves as a clear warning to discourage illegal passing maneuvers that could result in collisions, especially in areas where oncoming traffic is present or visibility is limited.

For instance, you might encounter a solid yellow line on winding roads, at intersections, or in areas where there is a high risk of accidents. This visual cue helps reinforce safe driving behaviors and ensures that drivers remain alert to the potential hazards in their vicinity.
