The Federal Highway Administration (FHWA) has announced the Notice of Proposed Amendment (NPA) to the Manual on Uniform Traffic Control Devices (MUTCD) and is soliciting comments. The proposed marked-up and a clean copy of MUTCD is at: https://beta.regulations.gov/docket/FHWA-2020-0001/document.
Following the comment period, FHWA staff will review and respond to the comments, and eventually publish a revision to the MUTCD later in 2021. This MUTCD is the basis for the California Manual on Uniform Traffic Control Devices (CA MUTCD), published by Caltrans and issued to adopt uniform standards and specifications for traffic control devices on all public roads in California. Once the national manual is published, Caltrans will update accordingly the CA-MUTCD within two years.
