Wide Solid White Edge Line

Extra-wide solid white edge line emphasizes the right edge of the travel lane.

An extra-wide solid white line along the right side of the roadway provides emphasis at locations where lane edge guidance is critical: narrow shoulders, rural highways at night, or sections with frequent run-off-road crashes. It functions like a normal right edge line but is more conspicuous; drivers should keep it on their left and avoid drifting onto the shoulder.
