Hazmat Endorsement 2026: Steps and $20 ELDT

The hazardous materials endorsement is the most involved endorsement to add to a commercial driver's license, and also one of the most valuable. Tanker, fuel, chemical and many general freight jobs either require it or pay more for it. Getting it means satisfying three separate agencies: the Federal Motor Carrier Safety Administration through Entry-Level Driver Training, the Transportation Security Administration through a background check, and your state licensing agency through a knowledge test.

The training part is the simplest of the three. Hazmat ELDT is theory only: 13 units set out in Appendix E to 49 CFR Part 380, from shipping papers and placards to bulk packages, emergency response and route planning, finished with an assessment you pass at 80% or higher. There is no behind-the-wheel training for H. Every unit is listed below.

This guide walks through each requirement in the order most drivers tackle them, then covers what happens when the endorsement comes up for renewal. If you are still working on the CDL itself, start with the basics of ELDT; the H endorsement can be added at the same time as your first CDL or later.

What is a hazmat endorsement?

A hazmat endorsement is the H code on a commercial driver's license that allows the holder to transport hazardous materials in quantities that require placards. It is one of the CDL endorsements listed in 49 CFR 383.93. Since February 7, 2022, getting it for the first time takes three things: ELDT hazmat theory from a provider on the FMCSA Training Provider Registry, a TSA Security Threat Assessment, and a passing score on your state's hazmat knowledge test. Held together with the tank vehicle (N) endorsement, it is shown on the license as X.

Who needs the H endorsement

Federal hazardous materials regulations require a driver to hold an H endorsement to transport any quantity of hazardous material that requires placarding under 49 CFR Part 172, and any quantity of certain select agents and toxins. In practice that includes fuel tankers, bulk chemicals, compressed gases, explosives, many industrial products and some radioactive materials. If the vehicle needs placards, the driver needs the endorsement.

Some drivers need it even when they rarely haul hazmat. Many carriers require the endorsement of all drivers so that any driver can be assigned any load. Fuel and chemical tanker jobs require both the N (tank vehicle) and H endorsements; the combination is coded on the license as X.

Under 49 CFR Part 380, ELDT applies to any driver obtaining the H endorsement for the first time on or after February 7, 2022. It does not apply to:

• Drivers who held the H endorsement before February 7, 2022 and are renewing it.
• Drivers who are only adding a tanker (N) or doubles/triples (T) endorsement, which are not covered by ELDT.

The endorsement is added to whatever CDL class you hold. A Class B driver delivering fuel in a straight truck and a Class A driver pulling a chemical tanker go through the same H endorsement process. If you are deciding between classes, Class A vs Class B lays out the difference.

What hazmat ELDT theory covers

The ELDT requirement for the hazmat endorsement is theory only. Unlike the passenger and school bus curricula, Appendix E to Part 380 has no behind-the-wheel section, so the whole ELDT portion can be completed online with a provider listed on the FMCSA Training Provider Registry.

Appendix E sets no minimum number of hours, but the provider must cover all 13 of its units:

1. Basic introductory HM requirements. The federal motor carrier safety rules that apply when hazardous materials (HM) are on board, and hazmat communication: shipping papers, marking, labeling, placarding, emergency response information and the shipper's responsibilities.
2. Operational HM requirements. The basic competencies for transporting hazardous materials.
3. Reporting HM crashes and releases. Who to notify immediately after certain hazmat incidents, and how to complete and submit a hazmat incident report.
4. Tunnels and railroad-highway grade crossings. Operating a hazmat vehicle at railroad crossings and in vehicle tunnels.
5. Loading and unloading HM. Loading and unloading procedures, segregation and securement of the cargo, and the ban on carrying certain poisons with foodstuffs.
6. HM on passenger vehicles. The rules for vehicles that carry both passengers and property, and which types and quantities of hazmat they can and cannot carry.
7. Bulk packages. Cargo tanks, intermediate bulk containers, bulk cylinders and portable tanks: emergency controls, special handling characteristics, the properties and hazards of the cargo, and how to prevent cargo tank rollovers.
8. Operating emergency equipment. Special precautions for fires and for loading and unloading, operating cargo tank equipment, and shut-off and shut-down equipment.
9. Emergency response procedures. Handling an emergency and what comes after it, including an unintended release, with the focus on protecting people, property and the environment.
10. Engine (fueling). How to fuel a vehicle that contains hazardous materials.
11. Tire check. Checking tires at the start of a trip and each time the vehicle is parked.
12. Routes and route planning. The routing rules for radioactive and non-radioactive hazardous materials.
13. Hazardous materials safety permits. Communications, constant attendance and parking rules for loads that require a hazmat safety permit (HMSP).

The state hazmat knowledge test has its own federal topic list in 49 CFR 383.121, which also names items such as the hazardous materials table, packaging, cargo segregation, attendance and parking, so expect the course and the test to overlap heavily.

To finish the course, you must pass the provider's written theory assessment with an overall score of 80% or higher. Because hazmat has no behind-the-wheel portion, the rule that makes other ELDT students finish theory and behind-the-wheel within one year of each other does not apply to H. In our experience, most students finish hazmat theory in a day or two of focused study, which makes it one of the quicker courses in the ELDT system; how long ELDT takes puts that in context with the other courses.

Our hazmat theory course costs $20. You pass every module quiz at 80% or higher, with retakes allowed until you do. To compare that with other providers and with the rest of your CDL budget, see what ELDT costs in 2026.

The federal deadline for a provider to report your completion to the registry is midnight of the second business day. With us it is automatic, usually within minutes of passing your final module, as long as your permit or license number is in your profile. Your state will check the registry before it lets you take the hazmat knowledge test, so make sure the name, date of birth and license number in your profile match your CDL exactly.

TSA threat assessment

The second requirement comes from the Transportation Security Administration. Before a state can issue or renew a hazmat endorsement, the driver must pass a TSA Security Threat Assessment. This is a federal background check created after 2001 to control who is allowed to transport dangerous cargo.

The process works like this:

1. Apply. You submit an application to TSA, either online or at an enrollment center. Eight states (Florida, Kentucky, Maryland, New York, Pennsylvania, Texas, Virginia and Wisconsin) run their own process that feeds into TSA, so check your state's instructions.
2. Enroll in person. You visit an enrollment center to have your fingerprints taken and your identity documents checked. Bring the documents listed in your application instructions.
3. Pay the fee. TSA sets the fee for the assessment, currently $85.25. If you already hold a valid TWIC card, a reduced fee may apply.
4. Wait for the result. TSA reviews criminal history, immigration status and other records. Processing commonly takes several weeks, and it can take longer if anything in your record needs a closer look.
5. Receive the determination. TSA notifies you and your state. Once you are approved, the state can add the endorsement after you pass the knowledge test.

Certain felony convictions, immigration issues and other factors can disqualify an applicant, either permanently or for a set period. If you receive an initial determination of threat assessment, there is an appeal and waiver process. A threat assessment approval is valid for five years.

Because this step is independent of ELDT and takes the longest, it makes sense to start it early. Many drivers apply for the TSA assessment first and complete their hazmat theory course while the check is pending.

State knowledge test

The third piece is the hazmat knowledge test at your state driver licensing agency. This is a written or computer-based test on the hazardous materials regulations, drawn from the hazmat section of your state's CDL manual. It covers the same ground as the ELDT theory course: identification and classification, shipping papers, placarding, loading rules, driving and parking rules, and emergency response.

Before you can take the test, the state will confirm that your hazmat theory completion is in the FMCSA registry. If it is not there yet, you will be turned away, so do not schedule the test for the same day you finish the course unless your provider has confirmed the record was submitted.

Passing scores and fees are set by each state. Once you pass, and once your TSA approval is on file, the state issues a new CDL showing the H endorsement, or an X if you also hold the tanker endorsement. Some states issue the updated license the same day; others mail it. Our state training pages collect the local steps and links: for example Texas and Pennsylvania, which run their own TSA enrollment, and California, Illinois and Georgia, which are not on that list.

Because the TSA approval, the registry record and the knowledge test all have to line up, it is worth calling your licensing office ahead of time to confirm what to bring. You will also retake the hazmat knowledge test each time you renew your CDL, as covered below.

Renewal

The hazmat endorsement does not last for the life of your CDL. Because the TSA threat assessment is valid for five years, the endorsement has to be renewed on that cycle, and in many states its expiration is aligned with your CDL renewal date.

Renewal requires a new TSA Security Threat Assessment: a fresh application, fingerprints and fee. TSA recommends starting the renewal well before the current approval expires, since processing time is similar to a first application. If the approval lapses, your state will remove the endorsement and you cannot legally haul placarded loads until it is restored.

Renewal does not require repeating ELDT. The federal training rule applies only to obtaining the H endorsement for the first time, so a driver renewing an endorsement they already hold has no new theory requirement, regardless of whether they first obtained it before or after February 7, 2022. The knowledge test is different: to keep H when you renew your CDL, federal rules require you to pass the hazmat knowledge test again, along with a current TSA assessment (49 CFR 383.71(d)(3) and 383.73(d)(4)), so plan on retesting at every CDL renewal.

If the endorsement lapses entirely, your state may treat you as a new applicant, which means a fresh TSA assessment and knowledge test before you can haul placarded loads again. Keep your TSA renewal on the calendar.

Taken in order, the path is straightforward: apply for the TSA assessment, complete hazmat theory online while it processes, pass the state knowledge test, and keep the five-year renewal on your calendar. The passenger and school bus endorsements follow a different path with behind-the-wheel training, and you can compare all endorsement courses on our course list.
