LA CDL HazMat Practice Test 2 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

New driving opportunities await you once you add a Hazardous Materials (HazMat) endorsement to your Louisiana commercial driver’s license (CDL). With this second free Louisiana OMV CDL HazMat endorsement practice test, you will take the next step in learning to safely transport such cargoes as gasoline, toxic chemicals, and industrial waste. You will find the instruction and support to build upon your existing skills and learn the rules and regulations for transporting materials deemed hazardous. The practice test is user-friendly and streamlines the learning process so you’ll receive the maximum benefits in a minimal amount of time. It’s like having your fill of Breaux Bridge crawfish before the season is over. The practice test introduces you to a better way of learning new skills.

With capabilities unmatched by other on-line resources, our Louisiana OMV CDL HazMat endorsement practice test can bring out your best performance. You must complete an entry-level driving course, undergo a Transportation Security Administration (TSA) background check, and pass an official knowledge test to obtain a HazMat endorsement. The official knowledge test requires you to correctly answer at least 80% of its 30 questions to pass. Using the practice test, you have access to a resource allowing you to develop a study plan that is fully capable of passing the official knowledge test on your first attempt. The practice test mimics the official knowledge test by providing 30 similarly worded questions to assess your current understanding. Based on your results, you can identify your challenges and focus on learning the information most crucial to your success.

Unlike traditional study guides, this Louisiana OMV CDL HazMat endorsement practice test creates a personalized learning experience. Study guides train you to memorize the answers to a series of questions, but the practice test goes further. Instead of memorizing the answers, the practice test equips you with the information that helps you make logical conclusions based on given driving scenarios. If you submit an incorrect answer, the practice test replies with a thorough explanation of the correct one. You can trust the information provided because it is taken directly from the most recent Louisiana OMV CDL manual (Louisiana CDL Handbook 2025) and is up to date as of December 2025. You’ll have full confidence in your ability to pass the official knowledge test and be ready to start the next adventure in your driving career.

Continuing your driver’s education is more convenient than ever with our series of practice tests. Whether you’re a beginner seeking a permit or a CDL driver wanting to learn how to operate air brakes, our practice test can prepare you for success in these pursuits and many more.

Strike up the jazz band, start a second line, and let’s celebrate a new way of learning excellent driving skills using the practice tests at https://driving-tests.org/louisiana/.

I am about to renew my license.
I have to do a Hazmat written and pass in order to keep my Hazmat endorsement. I have been studying for 3 days now and I took the Hazmat marathon and did not miss a single one I am ready for the test. It's an excellent program driving-tests.org has I really recommend it; I am pretty sure anyone can ace the test.

Skeptic turned Believer!
I failed the General Knowledge test the first time I took it using another companies study guide. Then I found driving-tests.org and I passed the General Knowledge, Air breaks, Combination, Tank, Doubles and Triples, and Hazmat all on the first try, inside one month!

It works! I was able to pass it on my first attempt.
99% of the questions on the test were in the study material so I was able to pass it quickly and easily. After completing the course, I concentrated on the Exam Simulator. I did it multiple times till I was at least averaging 98% each try. I would definitely recommend this course to anyone that needs there Hazmat endorsement.

Great website.
It's now required to take an ELDT course before a hazmat endorsement written test. So I found this website on Google. It gave me the course and practice test to prepare me for my hazmat exam date. I studied for 3 days (wed-Friday) took the test on Friday and passed. It's not easy but it's possible with this website. Thank you guys for making it easy and simple to study. Now it's time to make more money!
