National Standards for Traffic Control Devices; the Manual on Uniform Traffic Control Devices for Streets and Highways; Maintaining Minimum Retroreflectivity of Longitudinal Pavement Markings

Notice of proposed amendments (NPA).

The Manual on Uniform Traffic Control Devices (MUTCD) is incorporated by reference in 23 CFR part 655, subpart F, approved by the Federal Highway Administration, 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 proposes to amend the MUTCD to include standards, guidance, options, and supporting information relating to maintaining minimum levels of retroreflectivity for pavement markings. The proposed revisions would establish a uniform minimum level of nighttime pavement marking performance based on the visibility needs of nighttime drivers. The proposed revisions will promote safety, enhance traffic operations, and facilitate comfort and convenience for all drivers, including older drivers. The proposed revisions described herein would be designated as Revision 1 to the 2009 Edition of the MUTCD.
