Centerline marking refers to the painted lines on roadways that indicate the center of the lane. These markings help drivers maintain their position on the road and provide guidance for safe passing. Typically, centerlines are solid or broken yellow lines, with solid lines indicating no passing zones and broken lines allowing for safe overtaking when clear. In addition to enhancing safety, centerline markings are crucial for traffic management. They help organize vehicle flow and reduce the risk of head-on collisions. Proper maintenance of these markings is essential for their effectiveness, ensuring they remain visible under various weather conditions.
