How can you identify a no-passing zone?

A no-passing zone is identified by a solid yellow line on your side of the road. The solid yellow line indicates that it is illegal to pass other vehicles because visibility is likely limited or the road conditions are unsafe for passing. This line serves as a visual cue to warn drivers that they should not attempt to overtake other vehicles to avoid accidents. The solid line is a critical regulatory marker that emphasizes safety by prohibiting passing in areas where it could be dangerous. This is why recognizing the solid yellow line is essential for maintaining safety on the road.

The other options do not indicate a no-passing zone; for instance, a dotted white line often signifies that changing lanes is permissible, while traffic signals regulate overall traffic movement rather than specifically marking passing zones. Green signs are typically informational, such as guiding drivers or indicating distances to destinations, rather than providing indications about passing.
