Document Type



Certain hazardous materials transported by private motor carriers, for the purpose of direct support of their business (e.g. clinical and laboratory research) are exempt from most of the Department of Transportation (DOT) hazardous materials regulations, as long as they adhere to the requirements described in the Materials of Trade (MOT) exception. Ultimately, by reviewing this policy, personnel should gain a better understanding of the MOT requirements and be better prepared to transport hazardous materials for University business. Note: This exemption does not apply to the relocation/movement of laboratories on or between University of Health Sciences and Pharmacy in St. Louis campuses, nor the relocation or movement of hazardous waste.
