The Hazmat (Hazardous Materials) CDL permit test preparation tools are designed to help you study for the Hazmat written test you will take if you want to get a CDL with Hazmat Endorsement.


The Hazmat CDL permit knowledge test is required if you want to haul hazardous materials or waste in amounts that require placarding or any quantity of a material listed as a select agent or toxin in 42 CFR 73. This is an Endorsement to the CDL.  In order to obtain this Endorsement you are also required to pass a Transportation Security Administration (TSA) background check.

The tools below contain information needed to pass the CDL Hazmat test for driving a commercial vehicle that requires a Hazmat Endorsement for the driver.  You must take a test on this information to get a CDL with Hazmat Endorsement. These written tests are usually administered at your local DMV office.

In this course you will find two helpful tools.  Both are designed to help you learn the CDL concepts by using a “question and answer” format:

Course Content – This is another resource that is in quiz format.  Quizzes are broken into individual topics.  As you take the quizzes, you will see the correct answer.  Use the quizzes to learn important CDL concepts for the topic.

Practice Tests – Practice tests have audio available so you can listen to the questions.  You will be asked specific questions that may be on the CDL written test you will take to get your CDL permit or Endorsement. The tests give you the correct answer so that you can learn as you test.


The test questions are very similar to the questions you will see on the state CDL permit written test.

The following topics are included in Hazmat:

  • The Intent of the Regulations

  • Bulk Tank Loading, Unloading, and Marking

  • Driver Responsibilities

  • Driving and Parking Rules

  • Communications Rules

  • Emergencies

  • Loading and Unloading
