What is the primary purpose of orange signs in road work zones?

• A. To indicate speed limits
• B. To denote construction zones and guide traffic
• C. To decorate surroundings
• D. To indicate parking restrictions

Answer: (B)

Orange signs in road work zones are used to warn drivers that construction or maintenance is ahead and to guide traffic through or around the work area. The bright color signals a temporary condition, encouraging you to slow down, stay alert, and follow any detours, lane changes, or directions from workers or temporary controllers. This emphasis on temporary conditions is why they’re different from regular speed limit, decoration, or parking signs.
