FHWA to amend MUTCD

April 29, 2010

The Federal Highway Administration is accepting comment until April 22 on proposed amendments to its Manual on Uniform Traffic Control Devices that will establish a uniform minimum level of nighttime pavement marking performance.

A notice (.pdf file) published in the April 22 Federal Register said the proposed amendments would include standards, guidance, options and supporting information relating to maintaining minimum levels of retroreflectivity for pavement markings. FHWA officials said the proposed revisions are "based on the visibility needs of nighttime drivers" and will promote safety, enhance traffic operations, and facilitate comfort and convenience for all drivers.
