Which agency is primarily responsible for creating regulations regarding the safety of hazardous materials transportation?

The Department of Transportation (DOT) is the primary agency responsible for creating regulations regarding the safety of hazardous materials transportation. This responsibility includes the establishment of guidelines and standards that ensure the safe movement of hazardous materials by various modes of transportation, including road, rail, air, and water.

The DOT develops regulations that address the packaging, labeling, storage, and handling of hazardous materials to minimize risks to public safety and the environment during transport. Its regulatory framework is designed to ensure that all forms of hazardous materials transport are conducted in a way that mitigates potential accidents and injuries.

By overseeing these regulations, the DOT plays a critical role in coordinating efforts between different transportation sectors, stakeholders, and state agencies to promote safety standards throughout the transportation chain.
