Quick Answer
Texas drivers adding the Hazmat (H) endorsement to a CDL must first complete Hazmat ELDT theory training at a school listed on the FMCSA Training Provider Registry. The theory portion can be completed online. The Texas DPS Hazmat knowledge test, the TSA security threat assessment (including fingerprinting and background check), and Texas DPS processing of the endorsement are all completed separately, off-platform.
Get CDL Texas helps drivers compare CDL training and online ELDT theory options. ELDT is a federal training requirement, and Training Provider Registry-listed providers serve Texas drivers. Get CDL Texas is not the training school; the course is delivered by a third-party registered provider.
What Hazmat ELDT Is
Entry-Level Driver Training (ELDT) is a federal training standard set by the Federal Motor Carrier Safety Administration (FMCSA). For the Hazmat endorsement specifically, ELDT is theory-focused: it covers the regulatory and operational knowledge a driver needs to safely transport hazardous materials, including security awareness, shipping papers, placarding, loading and segregation rules, emergency response, and hours-of-service considerations.
Unlike Class A or Class B ELDT, the Hazmat endorsement does not have a behind-the-wheel skills component at the federal level. That's what makes Hazmat ELDT genuinely completable online: the course content matches the test content, and there is no in-vehicle hours requirement to satisfy separately.
Hazmat ELDT is theory training only. It is not a substitute for the Texas DPS Hazmat knowledge test, the TSA security threat assessment, or the Texas DPS endorsement application. Those are separate steps every Texas applicant still has to complete.
Who Needs Hazmat ELDT in Texas
The federal ELDT rule (effective February 7, 2022) applies to first-time applicants for the Hazmat endorsement on a Texas CDL. If you already hold a Hazmat endorsement and are renewing it, you generally do not need to repeat ELDT — but you do still need to renew the TSA security threat assessment every five years.
You should plan on completing Hazmat ELDT if any of the following apply:
- You hold a Texas Class A or Class B CDL and want to add the Hazmat endorsement for the first time
- You are getting your first Texas CDL and plan to add Hazmat at the same time
- You previously had a Hazmat endorsement that lapsed and are applying again
If you do not yet hold a Class A or Class B CDL, the Hazmat endorsement still requires an underlying CDL or Commercial Learner's Permit. For the broader chronological process — CLP, CDL, then endorsements — see How to Get a CDL in Texas.
Why You Must Complete Hazmat ELDT Before the Knowledge Test
Under the federal ELDT rule, your training provider reports your ELDT completion to the FMCSA Training Provider Registry. The state DMV — the Texas Department of Public Safety (DPS) in Texas — checks the Registry electronically before allowing you to sit for the Hazmat knowledge test. If your ELDT certification is not on file, Texas DPS will not let you take the test.
That's why ELDT comes first in the sequence. Drivers occasionally show up to a Texas DPS driver license office expecting to take the Hazmat test, only to be turned away because their ELDT record is missing. Confirm your provider has reported your completion to the Registry before you schedule the knowledge test.
What's Online vs. What's Still In Person
The clearest way to think about Hazmat for Texas drivers is to separate what a registered provider can deliver online from what only Texas DPS, the TSA, or another federal authority can complete.
✓ Can Be Completed Online
- Hazmat ELDT theory curriculum
- Knowledge checks and module assessments
- Final theory assessment for ELDT certification
- Provider reporting of completion to the FMCSA Training Provider Registry
✕ Completed Off-Platform
- Texas DPS Hazmat knowledge test (taken at a Texas DPS driver license office)
- TSA security threat assessment, including fingerprinting and FBI background check
- Texas DPS application and issuance of the endorsement
- Any document submission, fees, or in-person identity verification required by Texas DPS or the TSA
Completing Hazmat ELDT online does not mean your Hazmat endorsement is approved. Final approval depends on passing the Texas DPS knowledge test, clearing the TSA security threat assessment, and meeting all federal and Texas eligibility rules. Certain criminal convictions and immigration statuses are disqualifying under federal law.

Texas drivers adding a Hazmat endorsement generally complete these steps. The TSA security threat assessment can take time, so many drivers start it in parallel with ELDT rather than waiting until ELDT is finished.
-
1
Confirm Your CDL Eligibility You must hold or be in the process of obtaining a Texas CDL or CLP, be at least 21 years old (Hazmat is interstate-only), and not have a disqualifying offense on your driving or background record. See Texas CDL Requirements for full eligibility detail.
-
2
Complete Hazmat ELDT Theory Online Enroll in a Training Provider Registry-listed Hazmat ELDT course and complete the theory training. Your provider reports completion to the FMCSA Registry, where Texas DPS verifies it before scheduling the knowledge test.
-
3
Apply for the TSA Security Threat Assessment Schedule fingerprinting through the TSA Universal Enrollment Services portal. The TSA reviews your background, immigration status, and criminal history. Timing can vary, so start this step early and verify current instructions through the official TSA enrollment process. You can start this step before or during ELDT.
-
4
Pass the Texas DPS Hazmat Knowledge Test Once your ELDT is on file with the Registry, schedule the Hazmat knowledge test at a Texas DPS driver license office. The Texas CDL knowledge tests require a passing score per Texas DPS standards.
-
5
Apply for the Endorsement at Texas DPS After your TSA assessment clears and you've passed the knowledge test, Texas DPS adds the H endorsement to your CDL. Bring required identity and Texas residency documents to your appointment. Verify current Texas DPS requirements before your visit.
Texas CDL Requirements & Hazmat Eligibility
Hazmat is an add-on to an existing Texas CDL or CLP, not a standalone license. Three Texas-specific eligibility rules matter most for Hazmat:
1. Age 21 for Hazmat
Texas CDLs can be issued at age 18 for intrastate driving, but the Hazmat endorsement requires age 21. Hazmat hauling is treated as interstate commerce regardless of where the load goes.
2. Single-License Rule
You can only hold a CDL from one state at a time. If you hold a CDL from another state, you must transfer it to Texas before you can apply for the Texas Hazmat endorsement.
3. Texas Residency & Identity Documents
Texas DPS requires proof of Texas residency, identity, lawful presence, and Social Security number for CDL applications. Verify the current Texas DPS document checklist before your appointment so you don't make a wasted trip.

What This Course Does Not Do
So expectations are clear before checkout, here's what enrollment in an online Hazmat ELDT theory course explicitly does not provide:
- It does not guarantee Texas DPS will issue your Hazmat endorsement.
- It does not waive or replace the TSA security threat assessment, fingerprinting, or background check.
- It does not waive or replace the Texas DPS Hazmat knowledge test.
- It does not confer Class A or Class B CDL credentials. Hazmat is added to an existing CDL, not issued in place of one.
- It does not promise employment, earnings, or job placement once the endorsement is issued.
Hazmat endorsement training is for drivers who already hold a Class A or Class B CDL, or who are otherwise eligible to add a Hazmat endorsement under their state licensing rules. If you are unsure, contact us before purchasing.
