Free Louisiana CDL HazMat Endorsement Practice Test 2025

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

Louisiana is rich in diversity, whether driving through the Mississippi River areas and its wetlands, the coastal lowlands, or the congested urban cities like Baton Rouge and New Orleans. These diverse areas create countless opportunities for commercial drivers. Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) not only increases your marketability but also positions you for brighter recruitment prospects and higher earning potential! Let’s explore this endorsement, the state-specific opportunities it allows, and the tools we’ve created to help you obtain it.

The Hazmat endorsement permits drivers to transport materials that the U.S. government has judged hazardous. This responsibility is taken very seriously, and many additional requirements come into play. The several steps included in the endorsement process serve to ensure your safety and protect the people and environment. First, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check. Results from TSA can take weeks to arrive. You’ll want to use that time to study and practice for the second hurdle: the OMV knowledge test. The knowledge test addresses federal regulations, substance handling, material packaging, quantity limits, and transport configurations for hazardous materials. You’ll need a score of 80% on Louisiana’s knowledge test, which is made up of 30 questions (Louisiana CDL Handbook 2025).

Regarding additional opportunities, hazardous materials often transported in the Pelican State include crude oil and petroleum products (gasoline and diesel fuel), industrial chemicals (benzene and chlorine), natural gas and other compressed gasses, chemical fertilizers (anhydrous ammonia and ammonium nitrate), and hazardous waste and byproducts from the petrochemical industry. There are many high-level organizations in Louisiana that require the endorsement, including ExxonMobil (Baton Rouge), Dow Chemical (Plaquemine), Entergy Corporation (New Orleans), Sasol (Westlake), and Shell Oil (Norco).

Sounds overwhelming? Let’s fix that! Our online Louisiana OMV Hazmat Endorsement practice tests are strategically designed to avoid information not relevant to the test and mimic what you will face on the official OMV test. We also provide immediate feedback on each response, which studies have shown speeds the learning process. Once you receive your TSA results and feel ready, you’ll visit the OMV with the necessary documents, pay the fees, and pass the test with flying colors. What are you waiting for?

I love this website.
It helped me pass my state CDL exam - airbreaks, doubles and triples and tankers. I’m using it now to study for my hazmat. My daughter uses it to study for her regular drivers license for Louisiana. I would recommend it to anyone needing practice test for all DMV needs!

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
Great practice test system.
I studied for 1.5 days. I than went to the dmv and passed my general knowledge and hazmat first try! I would suggest this for anybody. Completing the primary practice test and using the practice test 5 times was enough to get me the answers needed!
R
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.
DAN
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!
