We provide quality on-site Road Way worker in-charge (RWIC) services, commonly called railroad flagman or railroad flagging. Flagging is used to direct traffic around road construction crews while they work. It is a crucial safety measure taken to protect the road construction workers and prevent traffic accidents. The degree of worker safety and driver safety is dependent on the knowledge and skill of the people doing the flagging. Safe Zone Traffic Control employs highly trained and skilled union flaggers, committed to public safety, courtesy and professionalism. We support our flaggers with strategic safety plans and high quality products.
