What does a solid white edge line mean?

• A. It marks the centerline of the road.
• B. It indicates a no-passing zone.
• C. It means you should stop at the line.
• D. It marks the edge of the roadway; do not drive off the pavement.

Answer: (D)

A solid white edge line marks the boundary of the paved roadway on the right side. It shows where the driving surface ends and the shoulder begins, and you should stay on the pavement rather than drive onto the shoulder or off the road. This line helps you keep the vehicle in the travel lane, especially in low visibility or when curves and high speeds make the edge harder to see. It isn’t a centerline or a stop line, and crossing it regularly isn’t advised; only leave the road if you’re entering a designated area and it’s safe to do so.
