Which color in the MUTCD indicates temporary traffic control?

The color that indicates temporary traffic control in the Manual on Uniform Traffic Control Devices (MUTCD) is orange. This color is specifically used for signage and devices that relate to roadwork, construction zones, and situations where traffic patterns are altered temporarily for safety reasons. Orange is easily recognizable and helps alert drivers to the presence of work zones, which may require them to slow down, maneuver around obstacles, or navigate through detours. This use of orange enhances visibility and communicates a sense of caution, which is essential for ensuring the safety of both workers and drivers in temporary traffic control situations.
