Which regulations govern the transport of Dangerous Goods in the United States?

The transport of Dangerous Goods in the United States is specifically governed by the Hazardous Materials Regulations (HMR), which are established by the Department of Transportation (DOT). These regulations provide comprehensive guidelines for the safe and secure transportation of hazardous materials by all modes of transport, including road, rail, air, and water. The HMR covers various aspects such as classification, packaging, labeling, handling, and emergency response measures for hazardous materials.

This regulatory framework is critical in ensuring that hazardous materials are transported in a manner that minimizes risks to public health, safety, and the environment. The enforcement of these regulations helps prevent accidents and incidents that could lead to exposure or catastrophic events involving dangerous goods.

Although the Environmental Protection Agency, Occupational Safety and Health Administration, and Food and Drug Administration each have their own important roles in regulating aspects related to hazardous substances, they do not specifically govern the direct transport of Dangerous Goods like the Hazardous Materials Regulations do. Therefore, the focus of the question is accurately answered by identifying the role of the DOT's regulations.
