Quick Answer
To add the Hazmat (H) endorsement to a CDL, drivers 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 state Hazmat knowledge test, the TSA security threat assessment (including fingerprinting and background check), and your state DMV's 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 drivers in multiple states. 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 state Hazmat knowledge test, the TSA security threat assessment, or your state DMV's endorsement application. Those are separate steps every applicant still has to complete.
Who Needs Hazmat ELDT
The federal ELDT rule (effective February 7, 2022) applies to first-time applicants for the Hazmat endorsement on a 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 Class A or Class B CDL and want to add the Hazmat endorsement for the first time
- You are getting your first 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. The state-issued CDL credential is a prerequisite, not something Hazmat ELDT can replace.
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. Your state DMV checks the Registry electronically before allowing you to sit for the Hazmat knowledge test. If your ELDT certification is not on file, the state will not let you take the test.
That's why ELDT comes first in the sequence. Drivers occasionally show up to a state DMV 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 ELDT is to separate what a registered provider can deliver online from what only your state DMV, 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
- State Hazmat knowledge test (taken at your state DMV office)
- TSA security threat assessment, including fingerprinting and FBI background check
- State DMV application and issuance of the endorsement
- Any document submission, fees, or in-person identity verification required by your state DMV or the TSA
Completing Hazmat ELDT online does not mean your Hazmat endorsement is approved. Final approval depends on passing your state's knowledge test, clearing the TSA security threat assessment, and meeting all federal and state eligibility rules. Certain criminal convictions and immigration statuses are disqualifying under federal law.

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 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. Eligibility specifics are set by your state.
-
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 your state DMV 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 Your State's Hazmat Knowledge Test Once your ELDT is on file with the Registry, schedule the Hazmat knowledge test at your state DMV. Passing-score requirements are set by each state.
-
5
Apply for the Endorsement at Your State DMV After your TSA assessment clears and you've passed the knowledge test, your state DMV adds the H endorsement to your CDL. Bring required identity and residency documents to your appointment. Verify current state DMV requirements before your visit.
Federal Eligibility & State Requirements
Hazmat is an add-on to an existing CDL or CLP, not a standalone license. Three rules apply to every applicant regardless of state:
1. Age 21 for Hazmat
Many states issue CDLs 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've moved, you must transfer your CDL to your current state of residence before applying for the Hazmat endorsement.
3. State-Specific Documents and Procedures
Beyond federal rules, each state sets its own document checklist, fee schedule, appointment process, and residency proof requirements. Verify your state DMV's current Hazmat application checklist before your appointment.

The Hazmat ELDT theory course on this site is delivered by an FMCSA Training Provider Registry-listed provider that serves drivers nationwide. The federal ELDT requirement is the same in every state. Your state DMV handles the knowledge test and endorsement issuance — verify your state's specific procedures with your state DMV before applying.
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 your state DMV 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 your state's 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.
