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.

LA28 Supplement to CA MUTCD 2026

The 2028 Los Angeles Olympics and Paralympics (LA28), which includes the Summer Olympics (July 14-30, 2028) and Summer Paralympics (August 15-27, 2028), will establish a Games Route Network (GRN) with dedicated lanes for Olympic Games vehicles to travel between venues and ensure athletes and Games personnel get to their events and venues on time. Some of the existing traffic control devices on roadways included in the established GRN will need to be changed temporarily, to allow identification of the priority lanes that have been dedicated for Games travel. Effective July 15, 2026, Caltrans has issued the LA28 Supplement to CA MUTCD 2026 (PDF) in support of Caltrans request for experimentation to FHWA for the non-standard use of light blue color as the background color for "LA28" on sign plaques and sign panels planned to be used for the established GRN during this large-scale special event.
