In what two ways are roads classified on a highway map?

• A. Designation or capacity
• B. Color and width
• C. Length and surface type
• D. Age and maintenance status

Answer: (A)

Roads on a highway map are classified by designation and capacity. Designation refers to the official type of route—interstate, U.S. highway, or state route—which signals the governing rules and standards that apply. Capacity reflects how much traffic a road is designed to handle, often related to the number of lanes and typical flow, so the map highlights major, high-capacity routes differently from smaller streets. While color or line width might help readers visually distinguish routes, they aren’t the formal basis for classification. Length, surface type, age, and maintenance status aren’t used to categorize roads on the map in the same way.
