FAQs and Answers About the HAZMAT Endorsement

Some commercial truck drivers qualify for additional endorsements on their CDL to become eligible for additional career opportunities. One of those endorsements is the Hazardous Materials (HAZMAT) endorsement. It’s a federal and state requirement for any commercial driver who wishes to transport hazardous materials, including gases, explosives, and flammable and combustible liquids.

Could I be disqualified from getting a HAZMAT endorsement?

Yes. Before you can earn it, you must undergo a rigorous Transportation Security Administration (TSA) background check. This background check will examine your criminal history, wanted or warrant status, and terrorist watch list status. Level A offenses will permanently disqualify you, but Level B offenses will only temporarily disqualify you.

What are the other requirements to get a HAZMAT endorsement?

There are some basic criteria you must meet. You must have a CDL of the right class, you must be of legal age to operate a vehicle with hazardous materials, and you must be either a U.S. citizen or able to show proof of legal status in the U.S.

Do I need to renew the endorsement?

HAZMAT endorsements must be renewed every five years. This is the federal requirement. It’s possible that your state will require a renewal sooner than this. Each time you renew the endorsement, you must submit to another background check and fingerprinting.

I was told I needed other endorsements too. What are they?

Not every HAZMAT driver needs additional endorsements. But if you want to operate a tanker, you’ll also need the N endorsement. Alternatively, the X endorsement is for the operation of a tanker, plus the transportation of hazardous materials.
