Conclusion
To address the comments to the docket, the FHWA adopts the following key changes to Section 2A.09 Maintaining Minimum Retroreflectivity in the MUTCD from what was proposed in the SNPA:
(A) In the STANDARD statement, a reference to Table 2A-3 was added to clarify that the levels contained in Table 2A-3 are the minimum levels that are to be used by public agencies or officials having jurisdiction when they develop an assessment or management method that is designed to maintain sign retroreflectivity.
(B) The 2nd SUPPORT statement was clarified to indicate that once an assessment or management method is used, an agency or official having jurisdiction would be in compliance with the STANDARD even if some individual signs do not meet the minimum retroreflectivity levels at a particular point in time.
(C) The GUIDANCE statement was modified by adding a sixth method to the list of assessment or management methods that should be used to maintain sign retroreflectivity titled “Other Methods,” which explicitly states that other methods developed based on engineering studies can be used.
In addition, FHWA adopts a 4-year compliance date (instead of the proposed 2-year compliance date) for implementation and continued use of an assessment or management method that is designed to maintain traffic sign retroreflectivity at or above the established minimum levels.
The final rule meets statutory requirements, provides clarity where needed, and provides flexibility for compliance.
