Traffic Control Field Manual for IDOT Employees

This Manual is issued for the purpose of the proper application of temporary traffic control devices for all employees of the Illinois Department of Transportation (IDOT) working on or near open traffic lanes. Work Zone Cases have been developed to establish the minimum requirements for work site protection, when traffic control is provided by the Department. IDOT employees providing inspection for contract work, permit work, or utility work shall work within the traffic control provided by the Contractor, Permit Holder, or Utility Company. Traffic control and work site protection measures for contracted work, permit work, or utility work shall be in accordance with the contract documents, permit documents, or the applicable IDOT Highway Standards for Traffic Control. Since Work Zone Cases call for the minimum requirements, additional devices should be added when necessary to enhance safety. These Work Zone Cases shall not replace traffic control highway standards placed within a contract or traffic control plan.
