What do edge and lane lines indicate on the road?

Edge and lane lines serve critical functions for drivers on the road. The primary purpose of edge lines is to delineate the boundary of the roadway, marking where the road ends and areas that may be unsafe or not intended for vehicular travel begin. This helps drivers stay within the lanes and provides guidance on the safe limits of the road.

Lane lines, which often appear as dashed or solid markings, indicate the direction and division of traffic flow in specific lanes. For instance, a dashed line permits lane changes, while a solid line discourages them. This clear visual guidance is essential for maintaining order and safety on the road.

Understanding the function of edge and lane lines is vital for safe driving practices, as it helps prevent accidents by ensuring that drivers maintain proper positioning on the roadway.
