In construction zones, what color may warning signs appear besides yellow?

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

Answer: (C)

In work zones, colors on warning signs are chosen to signal how the pavement conditions are changing and how temporary the situation is. Orange is used specifically for construction or maintenance activities, making signs stand out in the traffic environment and telling drivers that they’re entering a temporary work zone with workers, equipment, and potential detours. This targeted color helps you slow down and stay alert where conditions can change quickly. Yellow is the general warning color, but orange takes precedence in construction areas to indicate that the warning applies to ongoing road work rather than a permanent condition. Other colors have different meanings: blue signs point to services, red signs indicate prohibitions or stops, and green signs show directions or permitted movements, so they aren’t used to warn about construction hazards.
