What does an orange sign typically designate?

An orange sign typically designates roadwork or construction zones, indicating that there are temporary changes or hazards in the roadway due to construction activities. These signs serve an important safety function, alerting drivers to approach with caution, reduce speed, and be aware of workers and equipment present in the area. The use of orange for these signs is standardized because it contrasts well with other colors used for road signs and is highly visible, which is essential in temporary settings where conditions may change rapidly. This color coding helps ensure that drivers understand the nature of the zone they are entering, promoting safety for both workers and motorists.
