What does a solid yellow line on the road indicate?

A solid yellow line on the road indicates that passing is not allowed. This is a key traffic rule designed to enhance safety by preventing drivers from overtaking other vehicles in areas where visibility may be limited or the road conditions are potentially hazardous. When you see a solid yellow line, it warns drivers that crossing into the opposite lane for the purpose of passing is prohibited.

This means that drivers should remain in their lane and not attempt to overtake slower vehicles when a solid yellow line is present. In contrast, broken yellow lines would indicate that passing is permissible, as they suggest that the road is less dangerous for such maneuvers. By adhering to the guidelines associated with solid yellow lines, drivers help maintain safe driving conditions for everyone on the road.
