A solid yellow line on your side of the center line indicates what?

A solid yellow line on your side of the center line indicates that you must not pass over the line. This marking signifies that passing is prohibited in that area, primarily for safety reasons. Typically, this situation arises on two-way roads where visibility may be limited, or where conditions do not allow for safe passing maneuvers. The solid line serves as a clear visual cue to help drivers understand where it is unsafe to overtake another vehicle, ensuring safer travel for everyone on the road.
