Policy on Work Zone Traffic Control

The proper use of warning devices in roadway construction and maintenance work areas must be planned in advance to meet the individual requirements of the job site. The objective of this policy is to provide maximum protection to employees, plants, equipment, and the public while causing minimum interference to vehicular, bicycle, and pedestrian traffic. When guarding work areas, always provide more protection than may appear necessary rather than under-protecting. Inadequate protection may promote accidents by presenting the driver, bicyclist, or pedestrian with a false impression of the extent of the work area and the deviations that the traveler must take from the original route in order to safely pass the work area. Early project planning for traffic control in construction and maintenance areas, as well as implementation and surveillance of the controls during construction are very important.
