What is the standard color used for construction warning signs in Montana?

• A. Green
• B. Yellow
• C. Orange
• D. Red

Answer: (C)

Construction warning signs use orange. This color signals temporary conditions due to road work, making the signs immediately recognizable to drivers as different from permanent signs. Under MUTCD standards, orange is designated specifically for construction and maintenance warnings, while other colors have different purposes (green for guidance, yellow for general warnings, red for stop/prohibitions). The orange background with black lettering helps drivers slow down and follow posted instructions in work zones, which is why it’s used for construction warning signs in Montana.
