What color lines divide lanes of traffic moving in the same direction?

White lines are used to divide lanes of traffic that are moving in the same direction. This signaling helps drivers understand the flow of traffic and assists them in safely changing lanes or staying in their designated lane. White lines also often indicate the boundaries of lanes on multi-lane roads, ensuring that each vehicle remains in its respective lane and maintains proper spacing from other vehicles.

In contrast, different colors indicate various traffic regulations and conditions. For example, yellow lines typically separate lanes of traffic moving in opposite directions or mark the edge of the roadway. Colors like red and blue are used for specific purposes, such as designating no parking zones or marking certain types of parking spaces. Thus, the use of white lines is essential for maintaining safe and organized traffic flow in lanes moving in the same direction.
