What do black on orange signs indicate while driving on a highway?

Black on orange signs are specifically used to convey important information about road work zones and construction areas. These signs are designed to alert drivers to potential hazards, as well as to provide guidance on altered traffic patterns due to construction activities.

In work zones, it’s crucial for drivers to stay alert, as conditions can change quickly, and safety is a top priority. Hence, the use of black text on an orange background is significant; the contrast helps ensure that these signs are easily visible and quickly recognizable by motorists, promoting safer driving in potentially hazardous situations.

While other colors and sign types are used to convey different types of information, black on orange is uniquely reserved for work zone indications, making it essential for drivers to recognize and heed these signs when they encounter them.
