What indicates that you are in a highway work zone?

The presence of orange signs, cones, and markers is a clear indication that you are in a highway work zone. Orange is the designated color for construction and maintenance signage, which alerts drivers to potential changes in road conditions due to work being performed. These signs and markers are critical for ensuring safety by guiding traffic safely through or around hazardous areas where workers may be present.

Other options, such as red traffic signals and stop signs, are used for general traffic control and do not specifically indicate construction zones. Blue informational signs provide guidance about services and are not related to work zones, while yellow diamond-shaped signs serve as general warnings about road conditions but are not exclusive to construction areas. Thus, the use of orange elements is specifically tailored to communicate the presence of construction and maintenance activities on the roadway.
