What is the purpose of a solid yellow line on your side of the road?

A solid yellow line on your side of the road signifies a no-passing zone. This means that vehicles in your lane are not permitted to cross this line to pass vehicles in the opposing lane. The intent behind this marking is to enhance safety by preventing overtaking in areas where visibility is limited or where it may be hazardous, such as on hills, curves, or near intersections.

This line serves as a warning to drivers that there may be dangers ahead that could lead to accidents if passing were attempted. In contrast, other markings have different meanings: dashed yellow lines allow for passing, solid white lines indicate lane separation without passing, and markings for turning lanes or parking regulations serve different purposes.
