White lane markings are used to indicate lanes of traffic that are moving in the same direction. This means that when you see solid or broken white lines, they help to guide drivers within their designated lanes and facilitate smoother traffic flow in the same direction.

These markings also provide important visual cues for lane changes and merging, ensuring that drivers are aware of their position relative to other vehicles that are traveling in the same direction. It's crucial for maintaining order and safety on the road, as it helps prevent confusion about lane usage and encourages drivers to stay within their lanes.
