What does a white line on the side of the road indicate?

A white line on the side of the road signifies the edge of the roadway. This line provides a clear visual indication for drivers, helping them understand where the road ends and ensuring they stay safely within the traveled portion of the road. It is crucial for maintaining safe driving conditions and minimizing the risk of accidents, especially at night or in poor visibility conditions.

While pedestrian crossings are often marked with different types of lines or symbols, and center lines are typically solid or dashed yellow lines, the specific function of a white line on the side serves to delineate the roadway's boundary. Additionally, no parking zones might utilize different markings, such as signage or specific symbols, rather than relying solely on a simple white line. Thus, the primary purpose of the white line is to inform drivers about the limits of the road they are on.
