What does a solid yellow line on your side of the road mean?

A solid yellow line on your side of the road indicates that passing is prohibited. This means that drivers are not allowed to overtake or pass other vehicles while traveling in that lane. The purpose of this line is to enhance safety by signaling that visibility may be limited, such as around curves or hills, where passing could be dangerous. Therefore, if you see a solid yellow line, it serves as a clear directive to remain in your lane and not attempt to pass any vehicles.
