What is the role of the DOT in hazardous materials transportation?

The Department of Transportation (DOT) is primarily responsible for regulating the transportation of hazardous materials. This role involves developing and enforcing regulations that ensure the safe and secure transport of hazardous materials across the transportation system. The DOT's guidelines are designed to minimize risks associated with hazardous materials, such as potential spills, leaks, and other safety hazards, while promoting compliance among shippers, carriers, and facilities.

The agency establishes standards for packaging, labeling, and documentation to ensure that hazardous materials are transported safely. Additionally, it trains and certifies individuals and companies to ensure they understand the requirements associated with handling hazardous materials. This regulatory function is critical in preventing accidents and ensuring public safety.

While investigating hazardous incidents and issuing permits may be functions performed by different branches or related organizations within the broader DOT framework, the primary role of the agency in this context is to regulate and oversee the safe transportation of hazardous materials.
