Sign Designs and Markings Manual (SDMM)
This manual contains Standard Sign Designs for traffic control signs addressed in the Ohio Manual of Uniform Traffic Control Devices (OMUTCD) and the ODOT Traffic Engineering Manual (TEM), as well as some signs not yet specifically addressed in either of these manuals. The SDMM has been incorporated by reference into both the OMUTCD and the TEM. Therefore, although the SDMM is maintained by the Office of Traffic Operations, the on-line version continues to be housed on this Office of Roadway Engineering publications website with the other traffic engineering standards publications.
The SDMM can be viewed or downloaded below.
The SDMM is referenced in the OMUTCD and is used to assure uniformity in the design of standard traffic signs in Ohio.
If you have questions about the sign designs or need copies of older versions, please contact Jim Roth, Signing Engineer (614-752-0438).
You are welcome to also contact members of the Standards Section with questions or comments. Please use the Contacts link on the left.
