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

A solid yellow line on your side of the road indicates that passing is not allowed. This line is a regulatory measure designed to enhance safety on the roads. It delineates areas where visibility may be limited or where the road conditions do not permit safe overtaking of another vehicle. When you see a solid yellow line, it signals drivers to remain in their lane and refrain from attempting to pass vehicles, as doing so could increase the risk of a collision.

The other options suggest scenarios that do not align with the meaning of a solid yellow line. For instance, passing is expressly prohibited when you see a solid yellow line, contrasted with other situations where lane changes might be permissible or where passing could be allowed if marked by a broken yellow line instead. Knowing this helps drivers understand when they can safely maneuver on the road.
