The AASHTO Subcommittee on Highway Transport (SCOHT) is committed to ensuring the safe and timely transport of commodities intended to provide disaster relief in advance of and following a major disaster or emergency. Often these commodities result in the trucks carrying them to be in excess of the maximum allowable weight and length for travel on the U.S. interstate highway network.
Federal law authorizes States to issue special permits for trucks carrying commodities in excess of weight and length limits and that are not easily dismantled or divided (non-divisible), to move on the interstate highway network. Such commodities may include large generators and modular homes. Divisible loads remain subject to maximum allowable tolerances.
Recently enacted Federal legislation (MAP-21) now extends a State's authority to issue oversize and overweight special permits for interstate highway travel to include divisible loads of certain emergency relief commodities headed to other States that have been declared a national disaster area under the Stafford Act.
Motor carriers moving these goods must contact each State along their route to secure the appropriate permit and route information to ensure the safety and integrity of the infrastructure system remains intact.
Below is a list providing status information for motor carriers moving relief commodities. Motor carriers may contact Chris Smith, AASHTO at 202-957-6430 or John Nicholas, FHWA at 360-485-3503 for assistance in obtaining permits during non-business hours.
