Which symbol is used to represent a light-duty road (improved surface)?

• A. Double parallel lines
• B. Double dash parallel lines
• C. Single dash line
• D. Dotted line

Answer: (A)

Two solid parallel lines denote a paved, maintained roadway. In map symbols, this solid, continuous pattern communicates an improved surface suitable for standard vehicles, aligning with a light-duty road. Patterns that use dashes or dotted lines are typically reserved for less certain, unpaved, or narrower paths, which do not convey the same level of surface improvement. So the double solid lines best represent a light-duty road with an improved surface.
