What is the purpose of a temporary traffic barrier in the ROW?

• A. To support pedestrians
• B. To separate traffic from the work area and protect workers
• C. To decorate the site
• D. To indicate speed limit

Answer: (B)

Temporary traffic barriers in the ROW create a safety buffer between moving vehicles and the work area. They separate traffic from the work zone and protect workers by preventing vehicles from entering the space where crews are operating and where equipment is moving. This setup also helps channel traffic around the work site, reducing the risk of crashes and giving workers room to perform tasks safely. They are not meant to support pedestrians, decorate the site, or indicate speed limits, which are handled by other devices like sidewalks, pedestrian paths, and traffic signs.
