Are there minimum retroreflectivity requirements for pavement markings? If so, what are the expected standards?

Pavement marking retroreflectivity will be included as a revision to the 2009 National MUTCD and shall address the minimum retroreflectivity to mostly longitudinal pavement markings. The new standards are currently under review and will be implemented in the near future.

The proposed MUTCD text has been prepared and is currently under review and can be found at the FHWA’s website. Upon final rule approval of this section compliance for the implementation of a maintenance method will be required with four years and within six years the replacement of pavement markings that were identified as failing the minimum retroreflectivity is required.

The minimum retroreflectivity of pavement markings, based on the proposed ruling, are as follows:

These are the minimums proposed at this time and may change upon final ruling on the section and review by NYSDOT.
