Sign Retroreflectivity: A Minnesota Toolkit - Updated

The Minnesota LRRB has developed this Sign Retroreflectivity Toolkit, designed to provide local governments, especially small cities and townships, with guidance on FHWA’s sign retroreflectivity requirement as well as resources they can use to meet this requirement. (This toolkit was originally published in 2010 (2010RIC10 and updated in 2014.)

Current federal requirement: By June 13th, 2014 - Public agencies or officials having jurisdiction shall use an assessment or management method that is designed to maintain sign retroreflectivity at or above the minimum levels in Table 2A-3.

The toolkit includes a variety of resources:
• Know Your Retro – Maintaining Traffic Sign Retroreflectivity (FHWA-SA-07-020)
• 2014 Traffic Sign Retroreflective Sheeting Identification Guide (FHWA-SA-14-022)
• MN MUTCD Requirements – Official Minimum Retroreflectivity Requirements in Minnesota.
• Sign Assessment and Management Methods fact sheets
