Pavement Markings – Regulations / Standards

SUPPLEMENTAL NOTICE OF PROPOSED AMENDMENT (SNPA)

At this time, there are no federally required minimum levels of retroreflectivity for pavement markings. On April 22, 2010, a standard for maintaining minimum retroreflectivity of longitudinal pavement markings was published as a notice of proposed rulemaking in the federal register. A Supplemental Notice of Proposed Amendment (SNPA) proposes a revised set of standards to be incorporated in the MUTCD. The documents listed below are final drafts. The official version was published in the Federal Register on January 4, 2017, and may be viewed along with all the official supplemental documents at www.regulations.gov. Search for FHWA-2009-0139.
