MUTCD and California MUTCD

What's the Manual on Uniform Traffic Control Devices (MUTCD)?

The Federal Manual on Uniform Traffic Control Devices (MUTCD) sets the minimum standards governing all traffic control devices to improve safety and mobility for all roadway users and improve efficiency in the transportation system. The MUTCD is maintained by the Federal Highway Administration (FHWA) and is revised periodically with inputs from practitioners, agencies and other stakeholders. 

Technical AssistanceNon-compliance of the MUTCD can ultimately result in loss of federal-aid funds as well as significant increase in tort liability. The FHWA process to incorporate new devices and applications in the MUTCD involves the Federal Register rulemaking activity, to which any interested person or organization may provide input by submitting comments to the docket. Input from practitioners and all other stakeholders is very critical in keeping the MUTCD current and relevant.

Because the MUTCD is continually being updated and control devices are continually being introduced and evaluated, the FHWA maintains a table that lists the status of various bicycle-related signs, markings, signals, and other treatments as to whether they have been incorporated into the latest edition or whether they are considered experimental. Treatments that are not in the MUTCD or included in this table do not have standing with the FHWA.

What's the current version of the Uniform Traffic Control Devices (MUTCD)?

The 2009 MUTCD with Revisions 1 and 2 is the official current edition. 

What sections of the MUTCD are most relevant to bicycle safety? 

The section that is most relevant to bicycle safety is Part 9 Traffic Control for Bicycle Facilities.

What is the intended audience of the MUTCD?

The MUTCD audience includes, but is not limited to:

  • State and local highway agencies,
  • public officials,
  • owners of private roads open to public travel,
  • the insurance industry,
  • law enforcement agencies,
  • incident management personnel,
  • maintenance personnel,
  • academic institutions,
  • private industry,
  • and planning, construction and engineering organizations.

As of November 7, 2014, California Department of Transportation has adopted the California Manual on Uniform Traffic Control Devices (California MUTCD) 2014 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 2014 edition.

The California MUTCD 2014 edition includes FHWA’s MUTCD 2009 edition dated December 19, 2009, including Revisions 1 and 2, as amended for use in California.
