Harmonizing Commercial Vehicle (Truck) Weight Requirements for Emergency Transportation of Critical Commodities

During a declared emergency, states may temporarily implement regulatory relief of overweight commercial motor vehicles to better assist emergency response activities. Often, emergencies go beyond state boundaries, with a need to harmonize activities with surround states, creating issues for freight and the trucking industry. The objectives of this research were to assist state truck permitting offices to (1) develop consistent definitions of emergencies, emergency commodities (classification/type), and other concepts; (2) identify successful practices, procedures, and processes for increasing weight limits during emergencies, including coordination and harmonization with neighboring jurisdictions; (3) develop a decision framework that considers different emergency scenarios that are linked with successful practices, procedures, and processes; and (4) highlight successful communication practices and training opportunities to conduct before emergencies occur. This paper focuses on issues faced by state oversize/overweight truck permitting agencies when trying to successfully implement regulatory relief of overweight commercial motor vehicle requirements during emergencies.
