Final answer:
The white line on the right side of the road is known as the 'fog line' and indicates the edge of the roadway, helping drivers maintain their lane and marking the boundary between the lane and the shoulder.
Step-by-step explanation:
The white line on the far right side of the road typically indicates the edge of the roadway and it is often referred to as the 'fog line.' This line provides guidance for drivers, particularly in poor visibility conditions, to help them stay within their lane. It also marks the boundary between the lane and the shoulder of the road. In most regions, this edge line is a solid white line, and it serves a critical purpose in road safety by delineating where the pavement ends and the roadside begins.
