What is the significance of lane markings on the road?

Lane markings play a crucial role in guiding and regulating vehicle movements on the road. They are designed to provide clear visual cues for drivers, helping to maintain safe navigation and organization within traffic. For instance, solid lines generally indicate where lane changes are prohibited, while broken lines signify that changing lanes is permissible. By clearly delineating lanes, these markings help prevent accidents by ensuring that vehicles stay within their designated paths, reducing confusion and the potential for collisions. While rest areas may be indicated by signage, and aesthetics can sometimes be a secondary aspect of road design, the primary function of lane markings is to enhance safety and efficiency in traffic flow.
