What type of line separates two-way traffic?

A solid yellow line is used to separate lanes of traffic moving in opposite directions on a roadway. The presence of a solid yellow line indicates that passing is not allowed for traffic in either direction; it serves to provide a clear visual boundary for safety on two-way roads. This marking helps drivers understand that they should not cross the line to overtake another vehicle, which is critical in preventing head-on collisions.

In contrast, a solid white line typically separates lanes of traffic moving in the same direction, while a broken white line indicates that lane changes are permitted. A broken yellow line would suggest that passing is allowed if it is safe to do so, which does not apply to situations where a solid yellow line is present. Understanding these markings is essential for safe driving practices.
