ELDT hazmat training is a separate, specialized course you take after passing your general CDL knowledge test, not part of the standard ELDT curriculum

The Entry-Level Driver Training (ELDT) rule, which took effect in February 2022, requires all new commercial driver's license (CDL) holders to complete training through a Federal Motor Carrier Safety Administration (FMCSA)-registered provider before testing. However, ELDT itself does not cover hazmat endorsement training. If you want to haul hazardous materials, you must complete hazmat-specific instruction through a separate FMCSA-approved course, then pass the hazmat knowledge test at your state's Department of Motor Vehicles (DMV).

The distinction matters because ELDT covers general commercial driving skills — vehicle control, air brake systems, safe operating procedures — while hazmat training focuses on the regulations, placarding, documentation, and emergency procedures specific to transporting dangerous goods. You cannot combine them into one course, and you cannot skip ELDT just because you plan to haul hazmat.

Key Takeaways

  • ELDT is required for all new CDL holders but does not include hazmat instruction; hazmat training is a separate course you take afterward.
  • Hazmat training must be completed through an FMCSA-registered provider and covers federal regulations, shipping papers, placarding, and emergency response procedures.
  • After hazmat training, you must pass the hazmat knowledge test at your state DMV before the hazmat endorsement appears on your CDL.
  • Hazmat training providers vary in length and cost, so comparing FMCSA-registered schools in your area will show you the range of options available.
  • Your hazmat endorsement is valid for five years from the date your state issues it, then requires renewal through testing and a Transportation Security Administration (TSA) background check.

How hazmat training differs from general ELDT

ELDT covers the foundational skills every commercial driver needs: pre-trip inspections, backing, lane changes, braking, and the federal Motor Carrier Safety Regulations (FMCSRs) that explore to all commercial vehicles. A typical ELDT program runs 120 to 160 hours and includes both classroom and behind-the-wheel instruction. The course ends with the CDL knowledge test and, for most states, a skills test.

Hazmat training is narrower and deeper. It teaches the Department of Transportation (DOT) Hazardous Materials Regulations (49 CFR Parts 172–180), which govern how hazardous materials must be classified, labeled, packaged, and transported. You learn to read and complete shipping papers, understand placard requirements, recognize hazard classes, and respond to spills or accidents. Most hazmat courses run 8 to 16 hours and are classroom-only; they do not include driving instruction.

The two are sequential, not parallel. You complete ELDT first, pass your CDL test, then enroll in hazmat training. Some schools offer both programs and can schedule them back-to-back, but they are billed and tracked separately by the FMCSA.

What FMCSA-registered hazmat training covers

Hazmat training providers registered with the FMCSA must cover specific topics outlined in the agency's guidelines. These include hazard classification (how DOT assigns materials to classes like flammable liquids, oxidizers, or toxic substances), proper packaging and labeling, shipping paper preparation, vehicle placarding, loading and unloading procedures, and emergency response protocols.

You will learn the nine hazard classes and their subdivisions, how to identify materials by their shipping name and UN number, and what placards and labels must appear on your vehicle and packages. The course also covers your responsibilities as a driver — what you must do before accepting a hazmat load, how to handle a spill, and when to call emergency responders. Many courses include a section on the TSA security requirements for hazmat drivers, since a background check is part of the endorsement process.

The exact curriculum varies slightly between providers, but all FMCSA-registered courses must meet minimum content standards. Some providers offer online classroom instruction followed by an in-person exam; others conduct the entire course in person. A few offer accelerated formats that compress the material into a single day, while others spread it over multiple sessions.

The hazmat knowledge test and endorsement process

After you finish hazmat training, you take the hazmat knowledge test at your state DMV. The test is separate from your CDL written exam and typically contains 30 multiple-choice questions covering the material from your course. You must score at least 80 percent to pass. The test fee varies by state but usually ranges from $10 to $25.

Passing the hazmat test does not automatically add the endorsement to your CDL. Your state's DMV will issue you a new CDL with the hazmat endorsement (usually marked as "H" on your license) once you pass the test. However, before the endorsement becomes active, you must pass a TSA background check. The TSA reviews your criminal history, immigration status, and other factors to determine if you pose a security risk. This check can take several weeks.

If you fail the hazmat test, you can retake it. Most states allow you to retake it the same day or within a few days, though some require a waiting period. You do not need to repeat the training course to retake the test, but you may want to review the material before your second attempt.

Finding and comparing FMCSA-registered hazmat training providers

The FMCSA maintains a public registry of approved training providers on its website. You can search by state and city to find schools near you. The registry shows each provider's name, location, and whether they offer in-person, online, or hybrid instruction. It does not list prices or course schedules, so you will need to contact providers directly.

When comparing providers, ask about course length, format (online, in-person, or hybrid), and whether they offer flexible scheduling. Some schools offer evening or weekend classes to accommodate working drivers. Ask whether the course includes a practice test or study materials, and whether you can retake the course free if you fail the knowledge test. Prices typically range from $100 to $300, depending on the provider and format, but this varies by region.

Some trucking companies partner with specific training providers and may cover the cost of hazmat training for employees. If you are already employed, ask your company whether they have a preferred provider or will reimburse you for the course. If you are training on your own, budget for the course fee plus the DMV test fee and any materials.

Hazmat endorsement renewal and validity

Your hazmat endorsement is valid for five years from the date your state issues it. To renew, you must pass the hazmat knowledge test again and pass a new TSA background check. You do not have to retake the full training course to renew, though some drivers choose to take a refresher course to review changes in regulations.

The TSA background check is part of the renewal process and can take several weeks. If you have a criminal conviction, immigration issue, or other flag in your background, the TSA may deny your renewal. If that happens, you can appeal the decision, but the process is lengthy. It is important to understand that the hazmat endorsement is not may provide to renew; the TSA can revoke it at any time if new information comes to light.

Some states require hazmat drivers to renew their entire CDL (not just the hazmat endorsement) at the same time. Check your state's DMV website to confirm the renewal rules in your state, as they vary.

Why hazmat training is separate from ELDT

The FMCSA created ELDT to standardize training for all new commercial drivers and may support they meet a baseline of safety and knowledge. Hazmat training was kept separate because not all commercial drivers need it — many never haul hazardous materials — and the hazmat regulations are specialized enough to warrant their own course.

By keeping hazmat training separate, the FMCSA allows drivers to pursue it on their own timeline. You can get your CDL first, work as a general commercial driver, and add the hazmat endorsement later if a job opportunity requires it. This flexibility is useful for drivers who are not sure whether they will need the endorsement or who want to gain experience before specializing.

The TSA background check requirement for hazmat endorsement is also a security measure that applies only to drivers who will handle dangerous goods. It adds time and cost to the process, but it is a separate regulatory requirement from ELDT.

Frequently Asked Questions

Can I take hazmat training before I get my CDL?

No. You must have a valid CDL before you can hold a hazmat endorsement. However, you can enroll in hazmat training while you are waiting for your CDL test results or while you are studying for your CDL exam. Many providers allow you to complete the course early and take the hazmat test as soon as your CDL is issued.

Do I need hazmat training if I only haul certain materials?

Yes. If you haul any hazardous materials that require a hazmat endorsement under DOT regulations, you must have the endorsement. There is no partial or limited hazmat endorsement. Once you have the endorsement, you are authorized to haul any hazmat material for which you have proper training and your company approves.

What happens if I fail the hazmat knowledge test?

You can retake the test, usually within a few days. You do not need to repeat the training course, but reviewing the material before your second attempt is a good idea. Some providers offer practice tests or study guides to help you prepare for a retake.

How long does the TSA background check take?

The TSA typically completes background checks within two to four weeks, but it can take longer if additional investigation is needed. During this time, you have a CDL with the hazmat endorsement, but it is not yet active. Once the TSA clears you, your state DMV will notify you and the endorsement becomes fully active.

Can I get a hazmat endorsement if I have a criminal record?

It depends on the type and age of the conviction. The TSA has specific disqualifying offenses related to security and transportation. A conviction does not automatically disqualify you, but you should contact the TSA or a training provider to discuss your situation before enrolling in hazmat training and paying for the course.
