What does a solid yellow line indicate?

A solid yellow line on the road indicates that drivers are not permitted to cross or pass. This line is typically used to separate traffic moving in opposite directions, and crossing it could create unsafe conditions, particularly on two-lane roads where vehicles are traveling close to each other. The solid line serves as a visual cue signaling the need for caution, ensuring that drivers are aware of the potential dangers that could arise from passing another vehicle in areas where visibility or safety might be compromised.

The other options imply actions like passing or turning that are not permissible when a solid yellow line is present, which is why they do not align with the meaning of this traffic marking. Understanding the meaning of the solid yellow line is crucial for maintaining safety on the road and adhering to traffic regulations.
