Effective January 18, 2026, the California Department of Transportation (Caltrans) has issued the California Manual on Uniform Traffic Control Devices (CA MUTCD) 2026 to provide uniform standards and specifications for all official traffic control devices in California. CA MUTCD 2026 will replace CA MUTCD 2014 Revision 9 to meet substantial conformance with the 2023 Edition of the National Manual on Uniform Traffic Control Devices (National MUTCD 2023). This action was taken pursuant to the provisions of California Vehicle Code Section 21400 and the recommendations of the California Traffic Control Devices Committee (CTCDC). Caltrans has received a letter from the Federal Highway Administration (FHWA) for the CA MUTCD 2026 substantial conformance with the National MUTCD 2023 for Streets and Highways.
