When a traffic line is white, it means that traffic flows in one direction. White lines are used to delineate lanes on the road where vehicles travel in the same direction, helping to organize and manage the flow of traffic. This is particularly important on multi-lane roads and highways, where it is essential for drivers to stay within their designated lanes to maintain safety and reduce the risk of accidents. In contrast, yellow lines are typically used to separate lanes of traffic moving in opposite directions. Understanding this distinction is crucial for safe driving and adherence to road rules.
