What do solid yellow lines signify on the road?

Solid yellow lines on the road signify that passing is not allowed. This is an important safety measure designed to prevent drivers from attempting to overtake another vehicle when it could be dangerous. Typically, you will find solid yellow lines in areas where visibility is limited, such as curves or hills, or in situations where traffic regulations prioritize safety over mobility.

The presence of a solid yellow line indicates that crossing the line is prohibited, helping to regulate traffic flow and minimize the risks of head-on collisions. In contrast, other markings such as dashed yellow lines indicate that passing is permitted when it is safe to do so. Understanding the meaning of these road markings is crucial for safe driving practices and compliance with traffic laws.
