California Manual on Uniform Traffic Control Devices Branch

As of January 13, 2012 California Department of Transportation has adopted the California Manual on Uniform Traffic Control Devices (California MUTCD) 2012 edition to provide for uniform standards and specifications for all official traffic control devices in California. This action was taken pursuant to the provisions of California Vehicle Code Section 21400 and the recommendation of the California Traffic Control Devices Committee (CTCDC). The Department requested and has received a letter to confirm substantial conformance from the Federal Highway Administration (FHWA) for California MUTCD 2012 edition.

The California MUTCD 2012 edition includes FHWA’s MUTCD 2009 edition dated December 19, 2009, as amended for use in California. The California MUTCD 2012 also includes all policies on traffic control devices issued by the Department since January 21, 2010, and other corrections and format changes that were necessary to update the previous documents.

The California MUTCD 2012 edition supersedes and replaces the previously adopted (on January 21, 2010) California MUTCD as well as Chapters 4, 5, 6, 8, 10, 11, 12, and the traffic signals portion of chapter 9 of the 1996 Caltrans Traffic Manual, as amended, and all previous editions thereof.
