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

Answer: C — Passing is prohibited

A solid yellow line on your side of the road indicates that passing is prohibited. This marking is used to enhance safety by signaling that it is illegal to overtake another vehicle in that area, typically because of limited visibility or proximity to a hazardous area. These scenarios might include curves, hills, intersections, or other sections of the road where passing would be unsafe. While other options might suggest the possibility of passing under certain conditions—or indicate a lane intended for a specific type of vehicle—such distinctions do not apply when there is a solid yellow line. The presence of this line serves as a clear and straightforward message for drivers to remain in their lane and refrain from attempting to pass, thereby reducing the risk of collisions and promoting safer road conditions.
