MUTCD Regulation Compliancy Dates

The old 2012 – 2015 – 2018 compliancy dates were simplified with the passing of Revision 2 of the 2009 MUTCD edition that passed May 2012. The new regulation states:

June 13, 2014
All agencies will have to implement and continue use of an assessment or management method that is designed to maintain regulatory and warning sign retroreflectivity at or above the established minimum levels.

The MUTCD does not require replacement of any signs by a particular date; however, any sign identified as not meeting the established minimum retroreflectivity levels should be replaced as soon as possible.

It is also important to note that although the new compliance date only addresses regulatory and warning signs, agencies are instructed to add other signs types to the selected sign management method as resources allow. The FHWA simply felt that removing the compliance dates for various sign types better allow agencies to replace signs based on resources and relative priorities rather than specific compliance dates.

The changes were part of a larger initiative to simplify the MUTCD and ease the financial burden on agencies. Over 50 items incorporated in Revision 1 of the 2009 edition were affected by the May 14th ruling. The complete 2009 MUTCD Revision 2 Final Rule may be found at: www.regulations.gov; docket ID: FHWA-2010-0159.

Why the 922 Retroreflectometer?

Each day in the USA, traffic signs warn 200 million licensed drivers of road conditions, traffic patterns, speed limits and upcoming hazards, but a sign cannot help if it cannot be seen.

Over time, the elements (sun, rain, snow, dirt) wear down the reflective qualities of sign sheeting making them barely visible at night when signs are needed most. The safety risk posed by degraded sign visibility prompted the FHWA to outline in the MUTCD five approved methods government agencies may implement to monitor and maintain retroreflectivity levels of traffic signs.

The fifth method – actual sign retroreflectivity levels measured using a sign retroreflectometer – is quickly becoming the preferred method for ensuring roadway safety for hazardous nighttime driving. On average, agencies using this straightforward method have been able to safely reduce their annual sign replacements from 12-15% to as low as 2-3%.

The robust, yet intuitive, 922 sign retroreflectometer solution makes
compliance a simple matter:

Patented Annular technology and intuitive touch screen allows for quick and easy readings by any person with minimal training

Ease to read, definitive measurement of retroreflectivity removes human subjectivity from pass/fail rating ultimately saving money by eliminating unnecessary sign replacements

Included 922 software easily integrates collected data with several of the top GIS software systems without a further technology investment

Ability to add comments expands the data collection possibilities of the 922
