How to Get Your CDL Hazmat Endorsement: Tests, TSA Check, and Fees

To get a CDL hazmat endorsement, you need to complete federal entry-level driver training if it’s your first time, pass your state’s hazmat knowledge test, clear a TSA fingerprint-based security threat assessment, and pay roughly $85 in federal fees plus your state’s endorsement charge. Budget at least 60 days from the day you enroll with TSA, because the background check drives the timeline. Start early if you have a job start date tied to hauling placarded loads.

Finish Entry-Level Driver Training First

If you’ve never held an H endorsement before, FMCSA’s Entry-Level Driver Training rules require you to complete a theory course through a provider listed on the Training Provider Registry before your state will let you sit for the written test.1Federal Motor Carrier Safety Administration. Entry-Level Driver Training (ELDT) There is no behind-the-wheel component for the hazmat ELDT. Once you finish, the provider uploads your completion record to the Registry, and your state licensing agency checks that database before letting you test. You can verify the record yourself on the Registry’s portal using your CDL or learner’s permit number.2Training Provider Registry (FMCSA). Check Your Record

One exception: if you already held an H endorsement before February 7, 2022, ELDT doesn’t apply to you. The rule isn’t retroactive.3Federal Motor Carrier Safety Administration. Entry-Level Driver Training (ELDT)

Basic Eligibility

A hazmat endorsement is added to an existing commercial license, so a few things need to be in place before you apply:

  • A valid CDL in good standing, issued by the state where you live. If you’ve moved, transfer your CDL first.
  • Age 21 or older, matching the federal threshold for interstate commercial driving.
  • U.S. citizenship or lawful permanent residency. TSA’s threat assessment has immigration-status requirements you have to meet to be cleared.4eCFR. 49 CFR 1572.5 – Standards for Security Threat Assessments
  • A current Medical Examiner’s Certificate from a provider on FMCSA’s National Registry. These are valid up to 24 months, and letting yours lapse will trigger a downgrade of your CDL privileges.5Federal Motor Carrier Safety Administration. National Registry of Certified Medical Examiners6Federal Motor Carrier Safety Administration. Medical

Pass the Hazmat Knowledge Test

The written test is administered at your state DMV or licensing office and covers the hazmat chapter of your state’s CDL manual: the nine DOT hazard classes, placarding rules, loading and handling, shipping papers, route restrictions, and emergency response for spills and accidents. Most states require at least 80% to pass. The material is denser than general CDL training, so study the chapter carefully. If you fail, most states allow a retake after a waiting period that varies by state.

Don’t schedule the test until your ELDT completion record shows in the Training Provider Registry. Without it, the DMV won’t let you sit.

Complete the TSA Security Threat Assessment

Federal law prohibits any state from issuing a hazmat endorsement until TSA clears the applicant through a security threat assessment.7eCFR. 49 CFR 383.141 – General The assessment combines a fingerprint-based FBI background check with a review of immigration and intelligence databases. It’s the slowest step, so start it as early as you can.

How and Where to Apply

In most states, you pre-enroll online through TSA’s enrollment website and then visit an application center in person for fingerprints and document verification. If you hold your CDL in Florida, Kentucky, Maryland, New York, Pennsylvania, Texas, Virginia, or Wisconsin, you handle the entire process through your state DMV instead, because the state acts as TSA’s agent for enrollment.8Transportation Security Administration. HAZMAT Endorsement

Documents to Bring

Bring originals proving your identity and citizenship status. TSA gives you two paths:9Transportation Security Administration. TWIC and HAZMAT Endorsement Threat Assessment Program – Acceptable Documents

  • A single “List A” document that proves both identity and citizenship, such as an unexpired U.S. passport, a Permanent Resident Card, or a NEXUS card showing U.S. citizenship.
  • Or two documents: a valid photo ID (your CDL or a state-issued ID) plus a separate proof of citizenship such as a birth certificate, Certificate of Naturalization, or Consular Report of Birth Abroad.

Fee and Timing

The TSA fee is $85.25 for both new applicants and renewals, and it covers the fingerprinting and background check.8Transportation Security Administration. HAZMAT Endorsement Your state charges a separate endorsement fee on top of that, and the amount varies. TSA aims to return a determination within 60 days of your enrollment appointment, longer if fingerprints were hard to capture or your file is incomplete. TSA recommends applying at least 60 days before you need the endorsement.7eCFR. 49 CFR 383.141 – General

One shortcut: if you already hold a valid Transportation Worker Identification Credential (TWIC), your state can issue the hazmat endorsement without a separate TSA threat assessment, because TSA treats the TWIC background check as comparable.4eCFR. 49 CFR 1572.5 – Standards for Security Threat Assessments

Criminal History That Can Disqualify You

The background check is where applications get denied. Federal rules split disqualifying convictions into two groups.

Permanent Disqualifiers

Certain felony convictions bar you from a hazmat endorsement for life, regardless of how long ago they occurred, and no waiver is available. They include:10Transportation Security Administration. Disqualifying Offenses and Other Factors

  • Terrorism or related federal crimes as defined in 18 U.S.C. 2332b(g)
  • Espionage, treason, or sedition
  • Murder
  • Crimes involving explosives, including unlawful possession, manufacture, or distribution
  • Improper transportation of hazardous materials under 49 U.S.C. 5124
  • Causing a transportation security incident with significant loss of life, environmental damage, or economic disruption
  • Bomb threats against public facilities or transportation systems
  • RICO violations where a predicate act is one of the permanently disqualifying crimes
  • Conspiracy or attempt to commit any of the above

Interim Disqualifiers

A second group of felonies disqualifies you temporarily. You’re ineligible if you were convicted within seven years of your application, or released from incarceration within five years, whichever produces the longer wait.11eCFR. 49 CFR 1572.103 – Disqualifying Criminal Offenses These include unlawful weapons possession, sale, or distribution; extortion, bribery, or robbery; fraud, misrepresentation, or identity fraud (excluding welfare fraud and bad checks); drug distribution, possession with intent, or importation; arson; kidnapping or hostage-taking; rape or aggravated sexual abuse; assault with intent to kill; smuggling or immigration violations; and conspiracy or attempt to commit any of these.

If you’re denied for an interim offense, you can apply to TSA for a waiver. That means a written request explaining the circumstances of your conviction, along with court records, proof you completed your sentence, letters of reference, and other evidence of rehabilitation. TSA reviews waivers case by case. Drivers with permanent disqualifiers are not eligible.4eCFR. 49 CFR 1572.5 – Standards for Security Threat Assessments

Getting the Endorsement Added to Your CDL

Once you’ve passed the knowledge test and TSA has sent a “Determination of No Security Threat” to your state, go to your state’s licensing office to finalize. TSA communicates the clearance directly to the state, so you don’t need to carry paperwork proving you passed. Pay the state’s endorsement fee, and the H is added to your CDL.

Most states issue a temporary paper license while the permanent card is printed and mailed. Read the fine print: temporary paper licenses typically state they are not valid for hauling hazardous materials. You’ll need the physical CDL card with the H on it before you can legally move placarded loads, so plan for a week or two of waiting after your DMV visit.

Renewals and Moving to Another State

Hazmat endorsements don’t last forever. Federal rules require every state to renew them at least every five years, and each renewal triggers a fresh TSA threat assessment with new fingerprinting.7eCFR. 49 CFR 383.141 – General Your state must notify you at least 60 days before expiration, but track the date yourself rather than rely on the notice. The TSA renewal fee is the same $85.25.8Transportation Security Administration. HAZMAT Endorsement Most states also require you to retake the hazmat knowledge test at renewal.

Moving states resets things too. If you transfer your CDL to a new state, the hazmat endorsement doesn’t ride along automatically. TSA’s threat assessment program treats transfers the same as new applications and renewals, so you’ll clear the background check again in your new state.8Transportation Security Administration. HAZMAT Endorsement Whether the new state also makes you retake the knowledge test depends on its rules. The same 60-day processing window applies, so start the transfer well before you need to run hazmat loads from your new address.
