What is the purpose of a road sign displaying an orange color?

A road sign displaying an orange color is specifically used to indicate construction or maintenance work ahead. Orange is universally recognized as a color that signifies caution and alertness in situations where there may be temporary changes to the road conditions, such as detours, roadwork, or construction zones. This is crucial for ensuring the safety of both drivers and workers in these areas, as it alerts motorists to slow down and navigate with increased awareness of potential hazards or changes in traffic patterns.

While other colors serve distinct functions—such as red for stop signals or speed limit signs which are typically black and white—orange is exclusively associated with construction and maintenance activities. This distinction helps to streamline communication between the road authorities and drivers, promoting safe driving behaviors in active work zones.
