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).

Section 4511.11 of the Ohio Revised Code requires that all local authorities in their respective jurisdictions place and maintain traffic control devices in conformance with the OMUTCD.

Click here for a listing of the major differences between the 2003 Edition of the OMUTCD and the 2005 Edition.

The 2003 Edition of the OMUTCD adopted a sign code numbering system based on that of the national MUTCD. For a cross-reference guide between the old and new sign code numbers see Appendix E of the Sign Design Manual (SDM).

For those interested primarily just in that portion of the manual that deals with Temporary Traffic Control, Parts 1 (General), 5 (Low-Volume Roads), and 6 (Temporary Traffic Control) have been reprinted together in a separate publication.

For anyone with a government agency, local jurisdiction, school or public library, please contact the Standards Section to order this manual. Contacts
