Which agency primarily regulates transportation of hazardous materials?

The Department of Transportation (DOT) is the primary agency responsible for regulating the transportation of hazardous materials in the United States. This includes establishing safety standards for the entire transportation process, whether by road, rail, water, or air. The DOT oversees various administrations, including the Pipeline and Hazardous Materials Safety Administration (PHMSA), which specifically focuses on ensuring compliance and safety in the transportation of hazardous materials.

Regulating hazardous materials involves creating and enforcing regulations that help prevent incidents during the shipping process, focusing on areas such as packaging, labeling, and training for personnel handling these materials. This ensures that hazardous materials are transported in a safe manner, minimizing risks to public safety and the environment.

Other agencies listed have specific roles that may intersect with hazardous materials, but they do not primarily regulate their transportation. For instance, the Federal Aviation Administration oversees airline safety and operations, the Environmental Protection Agency focuses on environmental protection and regulations, and the Food and Drug Administration concentrates on food and medication safety.
