In the context of traffic signs, orange is used specifically to indicate temporary traffic control situations. This is commonly seen in work zones or areas where construction is taking place. The use of orange serves to alert drivers about the presence of temporary conditions that may affect the normal flow of traffic, including lane closures, detours, or reduced speed limits due to work activities. It is important for drivers to pay attention to orange signs as they signify changes in the usual driving environment and highlight the need for caution in those areas.

This color distinction is established within the Manual on Uniform Traffic Control Devices (MUTCD), which standardizes traffic control devices used on roadways to ensure consistency and clarity for drivers. In contrast, other colors serve different purposes: yellow typically indicates general warnings, red denotes stop or prohibition, and green directs traffic flow.
