What color and style represent major highways?

• A. Solid red
• B. Solid blue
• C. Brown dashed
• D. Green dotted

Answer: (A)

On maps, how a road is shown—its color and whether the line is solid or dashed—tells you how important that road is and what to expect when you drive it. A solid red line stands out and communicates a continuous, primary route for long-distance travel, which is exactly what major highways are. The bold, uninterrupted red cue grabs attention quickly and signals you can rely on this route for fast, easy travel across longer distances.

The other options would send different signals: a blue line is often used for other highway classes or map conventions, not the universal emphasis of a primary highway. A brown dashed line typically marks scenic, recreational, or less-than-primary routes and is not meant to denote major highways. Green dotted lines usually indicate bike paths or pedestrian routes, which are not highway corridors. So the combination of bold visibility and unbroken continuity makes solid red the best representation for major highways.
