__________ on your side of the road indicates a no-passing zone.

A solid yellow line on your side of the road indicates a no-passing zone because it is a traffic control device that defines the boundaries of lanes. When you see a solid yellow line, it signifies that passing is prohibited in that area. This is to ensure safety by preventing drivers from overtaking vehicles when it is unsafe to do so, such as in areas with limited visibility, curves, intersections, or other hazards.

In contrast, a dashed yellow line indicates that passing is allowed when it is safe to do so, while a solid white line typically separates lanes of traffic moving in the same direction and may discourage lane changes. No passing signs reinforce the no-passing message but are not the designated line marking themselves. The solid yellow line is the definitive marker that conveys the regulation against passing directly.
