What color lines are used to indicate left-edge lines on one-way roads?

On one-way roads, the left-edge lines are marked with yellow lines. This signaling is designed to clearly define the direction of traffic and provide a visual cue to drivers. Yellow lines are commonly used to separate opposing traffic flows or indicate the boundaries of driving lanes. On one-way roads, it is important for drivers to understand the layout of the roadway, and yellow lines serve as a guide to keep vehicles within the correct lanes and help prevent accidents.

In contrast, white lines typically delineate traffic lanes going in the same direction or are used for markings in parking areas, while red and blue lines are less commonly associated with standard lane markings in the context of roadway navigation and driver guidance.
