What color are warning signs typically in a work zone?

Warning signs in a work zone are typically orange for several reasons. The use of orange is standardized in the Manual on Uniform Traffic Control Devices (MUTCD), which establishes the colors, shapes, and symbols used in traffic control devices across the United States. Orange is recognized for its visibility and association with caution, especially in situations where there are construction or maintenance activities happening. This bright color stands out against various backgrounds, making it easier for drivers and pedestrians to recognize the presence of a work zone and the need to slow down or exercise caution.

In addition to visibility, the orange color effectively draws attention to potential hazards or changes in the traffic configuration, allowing for safer navigation through areas where there may be unexpected changes due to construction or maintenance operations.
