For those interested primarily just in that portion of the Ohio Manual of Uniform Traffic Control Devices (OMUTCD) that deals with Temporary Traffic Control, Parts 1 (General), 5 (Low-Volume Roads), and 6 (Temporary Traffic Control) of the OMUTCD have also been reprinted together in a separate publication titled the Temporary Traffic Control Manual. This separate publication is also often referred to as the "orange book" because of its orange cover.
This manual is available below for viewing or downloading. The file is set up for printing as a two-sided document.
The Ohio Revised Code (Section 4511.09) requires ODOT to adopt a manual for a uniform system of traffic control devices that conforms to the system approved by the Federal Highway Administration (FHWA). To this end, ODOT publishes the Ohio Manual of Uniform Traffic Control Devices (OMUTCD), which establishes standards for design and use of traffic control devices that conform to the national Manual on Uniform Traffic Control Devices (MUTCD) published by the Federal Highway Administration (FHWA). The TTCM is simply a reprint of portions of the OMUTCD.
Section 4511.11 of the Ohio Revised Code requires that all owners of private roads open to public travel and local authorities in their respective jurisdictions place and maintain traffic control devices in conformance with the OMUTCD.
The latest version of this manual is based on the 2012 Edition of the Ohio Manual of Uniform Traffic Control Devices (OMUTCD), published January 13, 2012 and effective April 12, 2012. A current list of "Known Errors" for the 2012 OMUTCD is posted on that website. A shorter version of the "Known Errors" list, addressing just the items related to the TTCM is also provided below.
Anyone getting a copy of the Temporary Traffic Control Manual (TTCM) is encouraged to sign up on the Design Reference Resource Center (or the Construction Reference Resource Center) to receive email notices related to the OMUTCD. (Updated: 5/2/16)
