Adding a Hazardous Materials (HazMat) endorsement to your Connecticut commercial driver’s license (CDL) qualifies you to transport additional cargo and experience increased earnings. Our free Connecticut DMV HazMat Study Guide is different from the traditional types that you may have previously used. Instead of memorizing the answers to a set of questions, you take a series of on-line practice tests to assess your knowledge and receive comprehensive instruction to better understand your most troublesome topics. It is crucial to possess a firm understanding of the rules and regulations for transporting hazardous materials to avoid the costly and severe penalties for non-compliance. Hazardous materials are subject to stringent packaging, labeling, and storage requirements. Gasoline, pesticides, and explosives are some of the materials subject to these requirements. Just as the Elm City is populated with trees that nourish the environment, you need to develop the skills to protect it.

Practice questions were identical to the actual HazMat test in Connecticut.
All of the material made it easy to study. I spent a few hours across 2 days going over the material and felt completely confident in passing. I passed with 25 questions (1 incorrect, overthinking it). This was also way easier and price was better than attending the trucking school where I obtained my CDL.
A
Excellent course.
I used this course to get my hazmat. It was easy to use. I appreciated the audio and visual format of the course. There were so many practice questions which was super helpful to pass the test. I took my test and passed with 100% in less than 5 minutes!
JS
I have been driving truck for almost 34 years.
I have been driving truck for almost 34 years and held a hazmat endorsement for quite a few of those years. DMV could not find any records of my hazmat endorsement, so in order to get my hazmat, I was required to take the ELDT training. I reluctantly put the money out for the training, passed and got my certificate. All said and done, I'm glad I did, because not only did it help me to remember some of my previous training, but I learned there was a lot I didn't know. I would recommend it to every driver.
SAD
I was able to do my ELDT online.
I was able to do my ELDT online and it was submitted immediately! I went to DMV and was in the system. Couldn't believe how quick it was! Passed my Hazmat endorsement test 1st time out. The information contained in the coursework made it a breeze to pass!

About the Connecticut CDL

Our second Connecticut DMV CDL HazMat endorsement practice test provides additional training to enhance your ability to safely transport hazardous materials. To earn a HazMat endorsement, you are required to complete a hazardous materials theory training program, submit to a Transportation Security Administration (TSA) background check, and pass an official knowledge test. You must answer at least 80% of the 30 questions on the official knowledge test to pass. The practice test includes 30 questions, mimicking those on the official knowledge test, to help you achieve this score.

This Connecticut DMV CDL HazMat endorsement practice test kickstarts the learning process with reliable information to overcome your learning obstacles. The practice test is based on the most recent Connecticut DMV CDL manual (Connecticut CDL Handbook 2025) and is up to date as of December 2025. If you submit an incorrect answer, you will receive a thorough explanation of the correct one to expand your knowledge. This interactive capability sets the practice test apart from traditional study methods as an encouraging and supportive resource. You’ll learn reliable information, be able to apply it to various driving scenarios, and increase your chances of passing the official knowledge test on your first try.

Using our practice tests, you will rapidly expand your skills. Each test, such as our CDL air brake practice test and our CDL pre-trip inspection practice test, uses the same format and offers an exceptional learning experience to support your success.

Drivers at Lime Rock Park race toward the finish line, and you can accelerate your acquisition of solid driving skills using the practice tests at https://driving-tests.org/connecticut/.
