Work Zone signs have orange backgrounds. They communicate road and hazard conditions in temporary areas such as construction and utility work. Refer to the MUTCD for more information.

While they are temporary signs, condition is extremely critical because travel through work zones can be hazardous with unexpected or unusual conditions. * Maintenance of signs and sign support: FHWA-SA-09-025
