What do orange signs typically alert drivers to?

Orange signs are used specifically to alert drivers to the presence of road workers and construction areas. This color is chosen for its visibility and serves as a warning for drivers to be extra cautious, as construction zones often involve potential hazards such as uneven pavement, changed traffic patterns, or workers present on or near the roadway.

By utilizing this highly visible color, road construction signs help in enhancing overall safety for both the workers and the motorists. In contrast, other colors serve different purposes; for example, blue signs indicate motorist services, while regulatory signs, like speed limits, appear in black and white. Understanding the meaning of these color-coded signs is crucial for safe driving and navigation on the roads.
