What does a solid white edge line indicate?

• A. It marks the center of the road; you may pass on both sides.
• B. It marks the boundary between two lanes of opposing traffic.
• C. It marks the edge of the drivable roadway; you should stay within the lanes and not cross except to avoid hazards or exit.
• D. It indicates a pedestrian crossing.

Answer: (C)

Solid white edge lines mark the boundary of the part of the road that is designed for driving. They define where the paved, drivable surface ends, so you should stay within the lanes and not cross this line except to avoid a hazard or when exiting the roadway. This line helps you maintain lane discipline and prevents drifting onto the shoulder or off the road. It’s different from center lines, which separate lanes of traffic moving in opposite directions, and from crosswalk markings, which indicate where pedestrians cross.
