LA CDL HazMat Practice Test 3 2025

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

Louisiana presents a lot of wonderful job opportunities for commercial drivers. Adding the Hazardous Materials (Hazmat) endorsement to your CDL immediately boosts your marketability and job opportunity pool, just what you need for higher earning potential!

The endorsement allows you to transport materials that the U.S. government has classified as hazardous. Because of the heightened responsibility, the process for endorsement includes several safeguards to protect you, the public, and the environment. After you’ve met the Entry-Level Driver Training (ELDT) requirements, you must submit fingerprints and a background investigation to the Transportation Security Administration (TSA). Results may take several weeks, so you’ll want to be strategic here. Apply for the TSA check and then use the wait time to study for the final requirement: passing the Louisiana OMV HazMat Knowledge Test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations. To pass, you must earn a minimum score of 80% on Louisiana’s 30 questions exam (Louisiana CDL Handbook 2025).

Hazardous cargo in the Pelican State frequently includes crude oil and petroleum products (gasoline, diesel), industrial chemicals such as benzene and chlorine, compressed gases like natural gas, fertilizers like anhydrous ammonia and ammonium nitrate, and hazardous waste from Louisiana’s petrochemical industry. Major employers relying on HazMat drivers include ExxonMobil (Baton Rouge), Dow Chemical (Plaquemine), Entergy (New Orleans), Sasol (Westlake), and Shell Oil (Norco). Without the HazMat endorsement, you won’t be able to legally transport these cargoes, and this pool of jobs will be closed to you.

Feeling overwhelmed by the amount of study material? Don’t worry! Our team of experts has simplified the process for you. Our practice tests are designed to mirror the official exam without the extra fluff that is not necessary for the test. You’ll also get immediate feedback after each answer, which has been scientifically shown to accelerate the learning process. This test is just one of the HazMat practice tests in our Louisiana-specific series, Once you’ve aced this one, check out another here: https://driving-tests.org/louisiana/la-cdl-hazmat-practice-test/.

Once you’ve completed all ELDT requirements, your TSA results are in (and you passed!), and you feel prepared to take the exam, take the required documents and fees to your local Louisiana OMV office. With our practice tests and your preparation, you’ll pass with flying colors and step immediately into higher-paying job opportunities.

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!
BS
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!
