Retroreflectivity plays a major role in maintaining nighttime sign visibility. The 2009 Manual on Uniform Traffic Control Devices (MUTCD) now requires all public agencies to adopt a sign maintenance program, which will help agencies meet these new requirements. Non-compliance with these new MUTCD requirements could put states and other public agencies at risk of losing federal funding for transportation projects.
The 2009 MUTCD states that one or more of the following assessment or management methods should be used to maintain sign retroreflectivity:
The assessment or management plan should be designed to maintain retroreflectivity at or above the minimum levels listed in Table 2A-3 on page 31 of the 2009 MUTCD: click here.
More information on traffic sign retroreflectivity is in Section 2A.07 and 2A.08 of the 2009 MUTCD: click here.
Agencies responsible for maintaining street signs have until January 22, 2012, to implement an assessment or management method. Compliance dates also have been set for replacing existing signs that do not satisfy the new minimum retroreflectivity requirements. The following table summarizes the compliance dates:
