What is HazMat?

Hazardous materials, often abbreviated as “hazmat,” are products that pose a risk to health, safety, or property during transportation. Some examples are explosives, flammable liquids, and radioactive materials. Strict federal and state regulations govern whether or how various hazardous materials can be transported by road. Most (but not all) types and quantities of hazardous materials can be transported only in a motor vehicle with placards (diamond-shaped signs) attached to identify the materials and their risks.

What is a HazMat endorsement?

An endorsement is an additional qualification that can be added to your Commercial Driver’s License (CDL) to allow you to drive certain types of vehicles or carry passengers or certain types of cargo. A Hazardous Materials (HazMat) endorsement qualifies you to transport hazardous materials in a placarded motor vehicle.

How to get it

You don't need any in-class training to get your HazMat. You can do it online in a few days. However, the TSA background check may take up to a month. To save time, you should start the TSA background check process immediately and let that go forward as a parallel track while preparing for the knowledge test). Here are the steps you must take to get a HazMat endorsement:

How to get a HazMat endorsement
  1. 1

    First, make sure you have a valid CDL

    A HazMat endorsement can only be added to an existing commercial driver’s license. Here's how to get a CDL if you don't yet have one.

  2. 2

    Complete a mandatory ELDT course

    The ELDT course must be from a provider approved by the Federal Motor Carrier Safety Administration (FMCSA). This requirement went into effect on February 7, 2022. Once you’ve completed the course successfully, your provider will issue your ELDT certificate and submit it to the federal Training Provider Registry (TPR). State testing centers can retrieve your certificate from the TPR and verify it.

  3. 3

    Pass the official written knowledge test

    The HazMat knowledge exam is typically administered by your state’s DMV or an authorized third-party testing facility. The written test will cover the material in the ELDT course and other HazMat-related topics. The good news? You won’t have to take any skills tests.

  4. 4

    Submit to a Security Threat Assessment

    The Security Threat Assessment is mandatory and is conducted by the Transportation Security Administration (TSA). You will be fingerprinted and undergo a background check. This process can take 60 days or longer. We recommend starting the process as early as possible so it can go forward while you are taking the ELDT HazMat course.
