How To Pass the California HazMat Test With Flying Colors

Passing a HazMat test is a good idea for commercial drivers who wish to gain more job opportunities. Not only would a Hazardous Materials Endorsement (HME) qualify you for more jobs, but you would also earn more money.

This article will break down the California HazMat testing process and provide tips on preparing for the test so that you can hit the road as soon as possible.

What Is a HazMat Test?

A HazMat test is a written knowledge test. It includes 30 questions, typically multiple-choice. It doesn’t entail a skills test like CDL tests.

To pass a HazMat test, you have to score 80%—i.e., have 24 correct answers.

You’ll find everything that could be on the test in the California commercial driver handbook, section 9: Hazardous Materials.

Here are the topics the test covers:

  • Emergencies
  • Driver responsibilities
  • Communication rules
  • Loading and unloading
  • Driving and parking rules
  • The intent of the PHMSA regulations
  • Bulk tank loading, unloading, and marking

Who Can Apply for a HazMat Endorsement?

To apply for a HazMat endorsement, you have to either own a CDL license or be in the process of applying for one so that the endorsement can be added to your license. If you don’t have a CDL, check out our guide on the California CDL test.

Aside from this, there are certain factors that could disqualify you and some requirements that are mandatory.

You can check your eligibility for a HazMat endorsement in the table below:



  • 21 years old
  • U.S. citizen
  • Lawful permanent resident
  • Refugee admitted under U.S. Code, Title 8 §1157 with a valid employment authorization document
  • Asylee under U.S. Code, Title 8 §1158 with a valid employment authorization document

Do I Need To Practice for the CA DMV HazMat Test?

Being a HazMat CDL driver is not a regular job. It comes with a lot of responsibilities and potential dangers. This is why you should take the HazMat test seriously and prepare for it accordingly.

If you study and practice enough, you’ll ace the test, which would help you become a great Hazmat CDL driver. When you practice for the test, you’ll also know all the regulations and procedures off the bat, and this will prepare you for any upcoming situations and issues.

Don’t let the test intimidate you. With the right study plan and plenty of time, you’ll pass it with flying colors—and we’re here to assist you!

How Do I Apply for a HazMat Endorsement?

Applying for a HazMat endorsement and obtaining it is a complicated process that includes a lot of steps and procedures. Not to worry—we’ll guide you through the whole affair.

TSA background check

Since hauling hazardous materials is a serious matter, not everyone can be a HazMat CDL driver. Each HazMat applicant must go through a background check or a security threat assessment with the Transportation Security Administration (TSA).

You need to pre-enroll for the security check either online or by calling the Universal Enrollment Services (UES) call center at 1-855-347-8371.

Once you complete the pre-enrollment, you should visit a UES center and submit your:

  1. Fingerprints
  2. Identity documents
  3. Citizenship/immigration documents

You should also pay the applicable fees with a money order, credit card, company check, or certified/cashier’s check. The TSA fee is $86.50, but if you own a TWIC card, you may qualify for a reduced fee of $67.

Scheduling a HazMat Test
