What does a construction traffic controller do?

As a construction traffic controller, you direct the flow of vehicles to help motorists avoid road work. Your responsibilities involve protecting drivers, pedestrians, and laborers by using flags to signal potential hazards. You use barricades, flags, traffic cones, signs, and hand signals to reroute cars and enforce applicable safety regulations and speed limits. As a construction traffic controller, your duties involve standing in a work zone on a road or highway and managing a steady flow of cars and trucks, sometimes during inclement weather. You need physical stamina as well as the ability to focus for an extended period.
