What does a yellow line mark on the road signify?

A yellow line on the road signifies that traffic is moving in opposite directions on a two-way road. This marking serves as a clear visual cue to drivers, indicating the separation of lanes for vehicles heading in different directions. It plays a crucial role in maintaining road safety by helping drivers stay in their designated lanes and reducing the risk of head-on collisions.

In contrast, a white line typically indicates lanes for traffic moving in the same direction, and solid yellow lines are often associated with no-passing zones. Pedestrian crosswalks are marked with different symbols or lines, usually associated with dashed white lines, specifically designed to alert drivers to the presence of pedestrians. Hence, understanding the meaning of these road markings is essential for safe driving.
