Getting a CDL with a HazMat endorsement isn't just about passing the hazmat knowledge test at the DMV. Since the Federal Motor Carrier Safety Administration's Entry-Level Driver Training (ELDT) rule took effect, there's a specific training requirement for new drivers seeking the HazMat endorsement — and it works differently from the Class A or Class B ELDT you might already be familiar with. This guide breaks down exactly how hazmat ELDT works, what's required, where to get it, and what comes next.
Hazmat ELDT is the entry-level driver training specifically required for obtaining — or upgrading to include — a HazMat (H) endorsement on a CDL. The FMCSA's ELDT rule, which went into effect on February 7, 2022, established that new CDL drivers (and existing CDL holders adding certain endorsements for the first time) must complete training from an FMCSA-registered Training Provider Registry (TPR) provider before they can take the state knowledge test.
The hazmat endorsement ELDT requirement applies to you if:
If you already held a HazMat endorsement before the ELDT rule took effect and you're simply renewing, you don't need ELDT for the renewal.
The FMCSA's hazmat ELDT curriculum has a specific set of required topics, established in 49 CFR Part 380. The training must cover:
The FMCSA specifies the topics that must be covered, but doesn't mandate a minimum hour requirement the way some states do for general CDL training. Training providers design their curriculum to cover all required topics — some offer this in a few hours, others through a multi-day program.
This is where candidates often get confused. Standard CDL ELDT (for Class A or Class B licenses) has two components: a theory portion and a behind-the-wheel (BTW) skills portion. The BTW portion is what makes Class A ELDT substantial — it requires on-road driving hours with an instructor.
Hazmat ELDT is theory only. There's no behind-the-wheel requirement. You complete classroom or online instruction on hazmat regulations, communications, handling, and emergency response, demonstrate understanding through an assessment, and you're done. It's a knowledge and compliance curriculum, not a driving training program.
This makes hazmat ELDT significantly more accessible and faster to complete than the Class A ELDT requirement, which mandates both theory and on-road hours and typically takes days or weeks at a licensed training facility.
Not all hazmat training qualifies for ELDT compliance. You must complete your hazmat ELDT from a provider registered in the FMCSA's Training Provider Registry (TPR). The TPR is the official federal database of training providers whose programs meet FMCSA's curriculum standards for ELDT.
When you complete training with a TPR-registered provider, the provider reports your completion directly to the TPR. When you go to your state DMV to take the hazmat knowledge test, the DMV is supposed to verify TPR completion before allowing you to test. A provider that isn't in the TPR can't report your completion, and your state may refuse to let you take the test — wasting your training time and money.
Before paying for any hazmat ELDT course, verify the provider is on the TPR. The FMCSA TPR is publicly searchable at tpr.fmcsa.dot.gov.
Yes — and this is one of the biggest advantages of hazmat ELDT compared to Class A ELDT. Because hazmat ELDT is theory-only, online completion is fully permitted. There are TPR-registered providers who offer hazmat ELDT entirely online, including the required theory instruction and knowledge assessment.
This matters practically: you can complete hazmat ELDT from home, on your schedule, without traveling to a training facility. For drivers who already hold a Class A CDL and are adding the HazMat endorsement, this is typically the fastest and most cost-effective path.
Costs for online hazmat ELDT from TPR-registered providers generally run $40–$150. Compare a few providers' TPR registration, curriculum structure, and pricing before selecting.
One requirement for the HazMat endorsement that sits outside of ELDT: the TSA threat assessment. Because the federal government considers access to hazardous materials a security concern, all CDL holders who obtain the HazMat endorsement must pass a TSA security threat assessment.
The process involves:
The TSA assessment typically takes 30–90 days, which means you often submit the fingerprints before or alongside your ELDT and knowledge test process. Plan your timeline with the TSA review period in mind — you can't get the endorsement until TSA clears you, regardless of how quickly you complete ELDT and pass the knowledge test.
After completing hazmat ELDT and receiving TSA clearance, you take the hazmat endorsement knowledge test at your state DMV. The test is drawn from the FMCSA's Hazardous Materials Handbook content, which mirrors what your ELDT curriculum covers:
Most states have 30–40 questions for the hazmat knowledge test with a passing score of 80% (varies by state). The content maps closely to your ELDT curriculum — studying your ELDT materials before the test is the most direct preparation.
The HazMat endorsement must be renewed on a regular cycle (typically every 5 years for the TSA background check component, though CDL renewal cycles vary by state). Renewal of an existing HazMat endorsement does not require completing ELDT again — the requirement is for first-time acquisition. However, the TSA security threat assessment must be renewed, which involves another fingerprint background check.
Hazmat isn't the only endorsement with an ELDT requirement. Other first-time endorsements requiring ELDT include:
Like hazmat, Passenger and School Bus ELDT are only required when obtaining the endorsement for the first time. Renewal does not require repeating ELDT.
