Which agency enforces regulations for the transportation of hazardous waste by highway?

• A. U.S. EPA
• B. State environmental agency
• C. Department of Transportation
• D. National Transportation Safety Board

Answer: (C)

When hazardous waste is moved by road, safety requirements for how it’s packaged, labeled, placarded, and transported—and who may handle it—are set and enforced by the Department of Transportation. DOT oversees the safety of moving hazardous materials on highways and handles the actual rules through agencies like PHMSA and FMCSA, covering packaging standards, labeling and placarding, vehicle and driver qualifications, routing, and training. The EPA’s role is focused on hazardous waste generation and disposal under the Resource Conservation and Recovery Act, not the transport phase. State environmental agencies enforce state-specific rules, but the federal enforcement for interstate highway transport rests with DOT. The NTSB, meanwhile, investigates accidents rather than regulate transportation safety.
