Traffic Control

Work Zone Safety and Mobility Rule:  Safety 3-07 Safety Engineering Policy 3-07 complies with the updated Federal Highway Administration (FHWA) work zone regulations at 23 CFR 630 Subpart J. The policy intent is to address safety and mobility issues starting early in project development and continuing through project completion. The goals are focused both on reducing fatal and serious injury crashes in work zones, coupled with minimizing work zone delays for motorists. This policy was developed in coordination with FHWA, affected IDOT bureaus and districts, and local agency representatives.

The health and safety of utility crews working on the right of way and the traveling public in work zones is among our main concerns, and all necessary traffic control should be used (signs, barricades, flaggers, etc.). Complete lists of Highway Traffic Control Standards are available on our Resources tab under Standards.

Message Boards may be required with the Traffic Control Standards to ensure public safety when traffic complexities and hazards arise.
