Free Montana CDL HazMat Endorsement Practice Test 2025

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

The vistas of Montana include the steep grades and winter snow of its mountainous regions (notably the Rockies) and the agricultural areas of the eastern plains with their expansive flatlands. Because the U.S. government has deemed certain materials hazardous, there are distinct advantages for drivers who obtain the right to transport these materials. Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is a fantastic way to expand your job opportunities and increase your earning potential!

In the Treasure State, hazardous materials transported include agricultural chemicals, oil and gas products, propane, mining explosives, and hazardous waste. Some prominent organizations in Montana, such as ConocoPhillips in Billings (a major player in the oil and gas industry), ExxonMobil Refinery also in Billings (transporter of refined petroleum products), Western States Equipment Company in Missoula (provides heavy equipment, including materials related to mining and construction), Phillips 66 in Laurel (specializes in refined petroleum and chemical transport), and Montana Rail Link in Missoula (a critical transporter of industrial goods, including hazardous materials for the agriculture and energy sectors) rely on Hazmat drivers. They are just a few of the many companies in the Big Sky Country requiring this endorsement.

“So, how exactly do I get this endorsement?” We’re glad you asked! Montana’s industry needs drivers like you. The process starts with a mandatory fingerprinting and background check conducted by the Transportation Security Administration (TSA). Do this right away as the results from TSA can take weeks, which you can use to study and practice for the second step: the MVD knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials. With a score of 80% on Montana’s 30-question knowledge test, you will pass the test (Montana CDL Handbook 2025).

If it all sounds overwhelming, don’t worry! Our online Montana MVD Hazmat Endorsement practice test are designed to avoid unnecessary information and resemble what you will face on the official MVD test. You will receive immediate feedback on each response, so you’ll learn quickly without waiting until the end for corrections. Once you receive your TSA results and feel prepared, you’ll visit the MVD with the necessary documents, pay the fees, and pass the test.

Took the DMV test and made a 100.
Studied all of the practice tests for 3 days, probably 6 hours in all. Took the DMV test and made a 100. What I didn't expect was that my overall understanding of transporting Hazmat is much better now after studying these tests than it has ever been.

Hazmat Certification.
This was the best and easiest way to get My Hazmat Endorsement. I struggled online finding a course i could take online and not pay so much money. I found driving-tests recommended on Reddit and was the best thing I've ever done. I got my Endorsement now and am talking with a company that requires it but is a way better opportunity for me and my family overall. I couldn't have done it without driving-tests and their easy, simple to understand and straightforward teaching course. I am definitely recommending this course to anybody thinking of getting their Hazmat Endorsement!

Second time's a charm!
I tried a couple other websites for some mock tests before taking the test for my hazmat endorsement. I thought I had it whipped. I failed. The DPS examiner handed me a CDL manual and told me to go home and study. I read the chapter for hazmat, but still didn't feel confident with my knowledge. After finding driving-tests.org, and going through the paces, I finally had the confidence I needed to succeed. This time I passed with flying colors! 100%. I couldn't have done it without you all!

Best Test Preparation.
It was great going in to take the actual HazMat DMV Exam feeling confident. Driving-Tests does an incredible job of getting you over prepared, this makes your test experience fail safe. In turn studying for the ELDT through their HazMat Course helps you bring a good amount of education with you to the job. Driving-Tests has an incredibly user friendly layout.

This is by far the best for ELDT.
I completed the course for Hazmat and tanker training in a week. They reported the results quickly, and taking the test at the DMV was a breeze. Questions on the tests were almost exactly in the same wording as the ELDT training. Great investment!

Driving-tests.org is the best of the best. Use it Today.
Driving Tests is a great website that I didn't know existed until a few weeks ago. I am in the process of getting my Hazmat and Tanker on my current CDL and a close relative is studying to get his CDL. He was considering going to school but I told him not to bother. He only needs to pass the written tests for the GK, the Air Brake, and the pre-trip. He's been driving underweight trucks for nearly 20 years but needs his "B" CDL to make himself a better asset for the company he works for. The driving part of the licensing process he already has down. This website has impressed me and makes it easy to study for my own tests and I'm 100% sure it will help him too. Thank you for making life much easier for me, and soon for him too. You guys rock!

93 of my 100 DMV CDL questions were exactly as they are written on this site.
I broke my exams into two segments, the General Knowledge, Air Brakes and Combination, and then I will study and go back for Tankers and Hazmat in a week or so. Despite an insanely loud exam room, and someone next to me reading every question on his tests out loud, I missed one question on 3 exams. And just like on this site, if you succeed, the exam ends immediately. Out of about 100 exam questions, maybe 7 were not on this site. The other 93 were written the same way you will see them here. But those 7 were not too hard. I only studied for 3 days and did not have time to study on the day of my exam. Seeing familiar questions and answers made taking the actual DMV exam very calming. To me this site was an inexpensive insurance policy to make sure I succeeded and could get my career going.
