Supplemental notice of proposed amendments (SNPA); request for comments.

The Manual on Uniform Traffic Control Devices (MUTCD) is incorporated in FHWA regulations and recognized as the national standard for traffic control devices used on all streets, highways, bikeways, and private roads open to public travel. The FHWA proposed in an earlier notice of proposed amendment (NPA) to amend the MUTCD to include standards, guidance, options, and supporting information related to maintaining minimum levels of retroreflectivity for pavement markings. Based on the review and analysis of the numerous comments received in response to the NPA, FHWA has substantially revised the proposed amendments to the MUTCD and, as a result, is issuing this SNPA.
