A sign with an orange background and black letters indicates which type of sign?

• A. Information signs.
• B. Construction zone signs
• C. Regulatory signs
• D. Warning signs.

Answer: (B)

Orange signs with black lettering are used for construction zones. The color orange is chosen specifically to signal temporary work-related conditions on or near the road, such as lane closures, detours, or workers ahead. The high contrast of black on orange makes the message stand out clearly in daylight and at night, helping drivers react in time to changing conditions. This type of sign is distinct from information signs (green or blue with white text), regulatory signs (white with black or red text), or warning signs (yellow with black text). So the sign indicates a construction zone.
