COLOR: Orange, with black letters or symbols.
MEANING: People are working on or near the roadway, and traffic may be controlled by a flag person. A work area speed limit as low as 25 MPH (40 km/h) may be posted. Even if no speed limit is posted, you must drive at a reduced speed through the work zone, and you must always obey flag persons. These illustrations show some of the signals a flag person will use. Know and obey them.
