Adequately maintained pavement markings improve nighttime visibility of highways and reduce the risk roadway departure crashes by bouncing light from vehicle headlights back toward the vehicle and the driver's eyes, making the pavement markings visible at a greater distance. This provides more time for the nighttime driver to react to changes in alignment. Because the retroreflective properties of traffic control devices deteriorate over time, highway agencies need to actively manage the maintenance of pavement markings in order to ensure that they are clearly visible at night.
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. Comment period closed August 20, 2010.
MUTCD Notice of Proposed Amendment – Federal
Register Notice [
Proposal for a standard for maintaining minimum retroreflectivity of longitudinal pavement markings published in the Federal Register on April 22, 2010. This document, developed as part of the rulemaking process, provides the background and detail explaining the proposal.
MUTCD Language – Maintaining Pavement Marking Retroreflectivity:
This link shows the proposed pavement marking retroreflectivity MUTCD Text. Note that this proposal was named Revision 1 to the 2009 MUTCD at the time this NPA was published. In 2011 FHWA published two additional Notices of Proposed Amendments. The amendments will actually be numbered in the order that the final rules become effective.

Revised Assessment of Economic Impacts of Pavement Marking Retroreflectivity:
Final Report: Revised Assessment of Economic Impacts of Implementing Minimum Levels of Pavement Marking Retroreflectivity. This updated report estimates increased costs of 3.2 percent of the current costs to implement the improved retroreflectivity of longitudinal markings in the proposed rulemaking.
