Which agency regulates the transportation of hazardous materials in the United States?

The Federal Motor Carrier Safety Administration (FMCSA) is the agency responsible for regulating the transportation of hazardous materials in the United States. This agency sets forth standards and regulations to ensure safe transport practices, particularly concerning the handling of hazardous materials (hazmat). The FMCSA enforces compliance for safety measures during shipment, including proper labeling, handling, and documentation required for hazardous materials.

This regulation is crucial for minimizing risks associated with the transportation of materials that could pose threats to public health, safety, and the environment if not managed properly. The agency's oversight includes issuing regulations that govern commercial motor vehicles carrying hazardous materials and educating drivers and carriers on safe practices.

The other agencies mentioned focus on different aspects of transportation and safety. The National Highway Traffic Safety Administration primarily deals with vehicle safety standards and increasing roadway safety. The Transportation Security Administration focuses on transportation security, especially related to aviation and critical infrastructure. The Federal Motor Carrier Administration pertains to administrative functions for motor carriers but does not specifically address hazardous materials.
