What do signs with an orange background typically indicate?

Signs with an orange background are specifically used to indicate work zones. This color is prominently chosen to alert drivers to construction areas, road work, or maintenance activities that may affect traffic flow and safety. The bright orange color is highly visible and serves as a warning, prompting drivers to exercise caution and possibly slow down due to the presence of workers, equipment, or altered road conditions.

In contrast, speed limit signs usually feature a white background with black text, while parking restrictions signs are typically displayed on a red, blue, or white background. School zone signage usually has a yellow or fluorescent yellow-green color to enhance visibility and alert drivers to the potential presence of children. Therefore, the association of orange with work zones is crucial for maintaining safety on the roads.
