Solid white lines mark the outer edge of roads, bike lanes, and turn lanes. Which option completes the statement?

• A. Center of the road
• B. Shoulders
• C. Outer edge
• D. Decorative markings

Answer: (C)

Solid white lines on the outside of the roadway define the boundary of the paved driving surface. They mark the outer edge where the road ends and the shoulder or bike lane begins, signaling you should stay within the travel lane and not cross the line casually. This is exactly what the statement is describing. The center of the road is usually marked by a center line (often yellow), the shoulders aren’t defined by a boundary line in the same way, and decorative markings aren’t used to indicate road edges.
