Road markings are painted lines and symbols on the surface of roads that help guide drivers and pedestrians. They indicate lanes, directions, and important information, such as stop signs and crosswalks. These markings are essential for maintaining order and safety on the roads, ensuring that vehicles and people can navigate effectively. Different types of road markings serve various purposes. For example, solid lines indicate that changing lanes is not allowed, while dashed lines show that it is safe to do so. Additionally, arrows may be used to direct traffic at intersections, helping to prevent accidents and improve the flow of vehicles.
