Federal Motor Carrier Safety Administration (FMCSA) and Department of Transportation (DOT) have issued a notice that contains the current National Hazardous Materials Route Registry (NHMRR). The NHMRR is a complete list, as reported by both the State and Tribal Government routing officials, of designated and restricted road/highway routes for the transportation of highway route controlled quantities (HRCQ) of Class 7 materials (RAM) and non-radioactive hazardous materials (NRHMs).
The current list contained in this notice will supersede the NHMRR that was published on July 14, 2014.
