What Is a Hazmat Endorsement?

A Hazmat endorsement is an additional certification that commercial driver's license (CDL) holders can obtain to transport hazardous materials. Hazardous materials can range from flammable liquids and gases to toxic substances and radioactive materials. Due to the potential risks involved in transporting these materials, the Federal Motor Carrier Safety Administration (FMCSA) mandates that drivers must have a Hazmat endorsement on their CDL.

  • Hazmat Knowledge Test: Applicants must pass a written test demonstrating their knowledge of hazardous materials regulations and safety practices.
