What do orange signs indicate on the road?

Orange signs on the road primarily indicate construction zones. These signs serve to alert drivers to areas where road work is taking place, which may include construction, maintenance, or repair activities. The use of orange is specifically designated to signal a temporary hazard, guiding motorists to approach these areas with caution, as conditions may change or there may be workers present on or near the roadway.

In contrast, signs indicating pedestrian crossings are typically marked in a different color, such as yellow or fluorescent yellow-green. Speed limit signs are white with black lettering, and detour signs are usually marked in a color distinct from orange, generally using a more vivid or clear color such as yellow or a specially designed shape to direct traffic away from construction activities. This is all part of the standardized traffic sign system aimed at promoting safety and clarity on the road.
