What color is a road closed sign?

• A. Red and white
• B. Black and white
• C. Yellow and black
• D. Orange and white

Answer: (D)

In work zones, color cues quickly tell drivers what kind of instruction they’re facing. Orange is used for construction and temporary maintenance zones, signaling that conditions ahead are temporary and related to ongoing work. White lettering on that orange background gives high contrast, making the message easy to read from a distance and in different lighting. So a road closed sign in orange with white text communicates a temporary, work-zone closure rather than a permanent rule or a general warning. Other color pairings serve different meanings—red and white for stop/prohibition, black and white for regulatory messages, and yellow and black for warnings—so they don’t convey the same temporary road-closure instruction in a work zone.
