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.
