What colors are the interstate signs?

• A. Red, White, and Blue
• B. Black and White
• C. Green and Yellow
• D. Purple and Orange

Answer: (A)

Interstate signs use a distinctive shield design that is instantly recognizable on the road, and the color scheme is red, white, and blue. The shield features a red border on top, a white field, and a blue interior with the route number in white, creating a striking contrast that drivers can identify quickly at speed. This combination is unique to the Interstate system, helping drivers distinguish these major highways from other types of signs. Other highway signs use different color schemes—green for directional guides, yellow for warnings, black and white for many regulatory signs—so the red, white, and blue palette is the defining look of interstate signs.
