Do you know your signs retroreflectivity? D. E. Gemmill, Inc. is your full-service retroreflectivity company to help you test your sign visibility, develop a plan and do traffic sign management and assessment to help you meet the compliance dates set forth by the Manual on Uniform Traffic Control Devices (MUTCD). According to the (MUTCD), the national standard for all traffic control devices used on any street or highway open to public travel. The MUTCD requires signs to be either illuminated or made with retroreflective sheeting materials and although most signs in the U.S. are made with retroreflective sheeting materials, they degrade over time resulting in a shorter life span. Until now, there has been little information available to determine how long the retroreflectivity lasts.

The MUTCD now requires that agencies maintain traffic signs to a set of minimum levels but provide a variety of maintenance methods that agencies can use for compliance.

The minimum retroreflectivity requirements do not imply that an agency must measure every sign. Rather, the new MUTCD language describes methods that agencies can use to maintain traffic sign retroreflectivity at or above the minimum levels.

Some important compliance dates to remember include:

June 13, 2014

Agencies shall establish and implement a traffic sign management and assessment program that is designed to maintain Regulatory and Warning sign Reflectivity at or above the established minimum levels. This compliance date does not require replacement by a particular date, rather it requires agencies to implement an assessment or management method for maintaining sign Retroreflectivity.

In addition, agencies will need to replace any sign they identify as not meeting the established minimum Retroreflectivity levels. Their schedules replacing the signs, however, would be based on resources and relative priorities, rather than specific compliance dates.
