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 previous version of the OMUTCD and the 2003 Edition. Also, 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 D of the Sign Design Manual (SDM).

A new edition of the national MUTCD was publish in December 2005 and we are in the process of preparing an update of the 2003 Edition of the OMUTCD based on this update of the national manual. To view draft proposed revisions of the OMUTCD click here.

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