Lane markings are painted lines on the road that help guide drivers and maintain order in traffic. They indicate where vehicles should drive, separate lanes for different directions, and show areas where passing is allowed or prohibited. Common types of lane markings include solid lines, dashed lines, and double lines, each serving a specific purpose. These markings are essential for road safety, as they help prevent accidents and ensure smooth traffic flow. In addition to guiding vehicles, lane markings can also indicate bike lanes and pedestrian crossings, contributing to the overall organization of the roadway for all users, including cyclists and pedestrians.
