If you want access to higher-paying loads and specialized freight, getting a HazMat endorsement is one of the most practical upgrades you can make to your CDL.
It allows you to legally transport hazardous materials—and qualify for jobs that require additional certification and responsibility.
In this guide, you’ll learn how to get a HazMat endorsement, including the requirements, steps, costs, and what to expect along the way.
What is a HazMat Endorsement?
A HazMat endorsement (HME) is a type of CDL endorsement —an addition to your CDL—that allows you to legally transport hazardous materials, which pose risks to safety, health, or the environment.
To get it, you must meet federal and state requirements, including:
- Passing a TSA background check
- Completing required training
- Passing a knowledge test
In simple terms, without a hazmat endorsement, you cannot legally haul hazardous materials.
What Is a Hazardous Material?
The U.S. Department of Transportation (DOT) defines hazardous materials as substances that pose a risk to health, safety, property, or the environment when transported.
In simple terms, these are materials that can be dangerous if not handled properly during transit.
Common examples include:
- Flammable liquids (fuel, gasoline)
- Explosives and certain chemicals
- Gases and toxic substances
- Radioactive or corrosive materials
Because of these risks, hazardous materials are strictly regulated to protect people, infrastructure, and the environment.
What are the Different Types of HazMat Endorsements?
Unlike other CDL endorsements, HazMat itself is a single designation—known as the “H” endorsement. However, it’s often combined with other endorsements depending on the type of freight you plan to haul.
Here’s how it breaks down:
- HazMat Endorsement (H)
Allows you to transport regulated hazardous materials such as chemicals, gases, and flammable liquids. Requires a knowledge test and a TSA background check. - Tanker Endorsement (N)
Required for transporting liquids in bulk containers (typically over 1,000 gallons). Focuses on handling liquid movement and vehicle stability. - HazMat + Tanker (X Endorsement)
A combination of H and N is required for hauling hazardous liquids like fuel or certain chemicals. Common for fuel haulers and chemical transport drivers.
How to Apply for HazMat Endorsement
Getting a HazMat endorsement involves a few key steps—training, background checks, and testing. Follow them in order, and the process is straightforward.
Steps to Get a HazMat Endorsement
1. Meet the basic requirements: Make sure you have a valid CDL, meet age and residency requirements, and hold a current DOT medical certificate.
2. Complete Entry-Level Driver Training (ELDT): Finish the required hazmat theory training through an FMCSA-approved provider before taking the test.
3. Start your TSA background check: Pre-enroll by submitting your information online or through an enrollment service.
4. Visit a fingerprinting center: Provide fingerprints, verify your identity, and pay the background check fee at an authorized location.
5. Submit your HazMat application: Complete your state’s application process, either online or in person, depending on requirements.
6. Pass the HazMat knowledge test: Take the written exam at your local DMV. It covers safety, regulations, and handling procedures. Most states require a score of 80% or higher.
7. Wait for TSA clearance: Background check approval typically takes 2–6 weeks.
8. Complete final DMV processing: Submit required documents, confirm your test results, and pay any remaining fees.
9. Receive your updated CDL: Once approved, your CDL will be updated with the HazMat endorsement.
What is HazMat Certification?
HazMat certification refers to the training and preparation required to safely handle and transport hazardous materials.
It typically includes:
- Entry-Level Driver Training (ELDT) and test preparation
- Safety procedures and handling guidelines
- Labeling and emergency response practices
While the HazMat endorsement is the legal authorization on your CDL, certification reflects your training and readiness to handle hazardous materials.
HazMat Theory Requirement & ELDT Mandate
Under current FMCSA regulations, all drivers must complete Entry-Level Driver Training (ELDT) before applying for a HazMat endorsement.
Key requirements:
- Training must be completed through a provider listed on the FMCSA Training Provider Registry
- It must be finished before taking the DMV knowledge test
The training covers:
- Hazardous materials regulations
- Safety procedures
- Load handling and emergency response
