Interstate highways are identified on signs with what kind of shape?

• A. Circle
• B. Shield
• C. Rectangle
• D. Diamond

Answer: (B)

Interstate highways use a shield-shaped sign. This shield silhouette is a nationwide cue that quickly tells drivers they’re on the nation’s primary, limited-access routes, no matter what state they’re in. The shape is designed to stand out from other signs—diamonds warn of hazards, rectangles carry information or directions, and circles are used for different, specific purposes—so the shield instantly signals an Interstate. You’ll often see the shield with the word “Interstate” and the route number, but the key idea is the shield shape itself as the identifying mark.
