How to Get a Hazmat Endorsement (H) for Your CDL
If you want to increase your earning potential and expand your job opportunities as a commercial driver, adding a Hazmat endorsement (H endorsement) to your CDL is a smart move.
Drivers with a Hazmat endorsement are qualified to transport hazardous materials such as fuel, chemicals, and other regulated substances. Because these loads require additional responsibility and compliance, the process to earn the endorsement is more detailed than other CDL add-ons.
Here’s a step-by-step breakdown of how to get a Hazmat endorsement and what to expect along the way.
What Is a Hazmat Endorsement?
A Hazmat endorsement (H) allows CDL holders to transport materials classified as hazardous under federal law. These materials are regulated by the Federal Motor Carrier Safety Administration (FMCSA) and the U.S. Department of Transportation.
Common examples of hazardous materials include:
- Gasoline and diesel fuel
- Industrial chemicals
- Compressed gases
- Certain medical or radioactive materials
Because of the potential risk involved, drivers must complete additional training and pass both a written exam and a federal background check.
Step 1: Complete ELDT Hazmat Theory Training
As of February 7, 2022, drivers must complete Entry-Level Driver Training (ELDT) for Hazmat before taking the state knowledge test. This theory training must be completed through an FMCSA-registered provider.
C1 offers compliant ELDT Hazmat theory training, which you can review here: ELDT Hazmat Theory Training.
For drivers who prefer maximum flexibility, C1 also offers a fully online option: Online ELDT Hazardous Materials Endorsement Theory Training Course .
Online ELDT Hazmat training allows you to complete required coursework at your own pace while ensuring your completion is properly submitted to the FMCSA Training Provider Registry.
Step 2: Complete a TSA Background Check
Before your state can issue a Hazmat endorsement, you must pass a Transportation Security Administration (TSA) background check.
This includes:
- Fingerprinting
- Identity verification
- Criminal history review
- Citizenship or lawful permanent resident verification
The background check helps ensure drivers transporting hazardous materials meet federal security standards. You must receive TSA clearance before your endorsement can be finalized.
Step 3: Pass the Hazmat Knowledge Test
After completing ELDT theory training and beginning the TSA clearance process, you’ll take the Hazmat written test at your state’s licensing agency.
The exam covers:
- Hazard classifications
- Placarding requirements
- Loading and segregation rules
- Emergency response procedures
- Federal regulations
Once you pass the test and your background check clears, the Hazmat endorsement will be added to your CDL.
State-Specific Hazmat Requirements
While the federal ELDT requirement applies nationwide, the exact process can vary slightly by state.

Why Add a Hazmat Endorsement?
Many drivers choose to add a Hazmat endorsement because it:
- Increases job opportunities
- Can lead to higher pay
- Makes you more competitive with employers
- Opens doors to tanker and fuel hauling positions
Carriers often prioritize drivers who hold multiple endorsements, especially when transporting regulated freight.
