Free Minnesota CDL HazMat Endorsement Practice Test 2025

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

Transporting cargo across Minnesota’s rolling plains, extensive lakes, and river valleys, especially along the Mississippi River, offers a unique mix of beauty and challenges. From navigating the snow and ice of its winter weather to the occasional spring flood, you’ll face a pretty dynamic environment. Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) prepares you to meet these challenges while transporting cargo that only a special kind of driver can haul. It opens the door to more job opportunities and may result in higher pay!

The Hazmat endorsement enables drivers to transport materials classified as hazardous by the U.S. government. In the North Star State, hazardous materials include ethanol, ammonia (used in agriculture), petroleum products, and industrial chemicals. Some prominent organizations in Minnesota, such as Cargill, Inc. (Wayzata) with its agricultural chemicals and biofuels, 3M (Maplewood), a huge worldwide organization with its industrial and specialty chemicals, and Flint Hills Resources (Rosemount), a major petroleum refinery, rely on skilled drivers with the Hazmat endorsement for these logistics needs.

The Hazmat endorsement process is designed to ensure that drivers with this credential are well-trained to safely transport these materials. As such, there are several steps in place. The process starts with a mandatory fingerprinting and background check conducted by the Transportation Security Administration (TSA). Results from TSA can take weeks, so you’ll want to study and practice in the meantime for the second step: the DVS knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials and requires a score of 80% to pass. Minnesota’s 30-question knowledge test, once passed, moves drivers closer to unlocking new opportunities (Minnesota CDL Handbook 2025).

Don’t worry if this process seems overwhelming. Our online Minnesota DVS Hazmat Endorsement practice tests are designed to avoid unnecessary information and are streamlined to resemble what you will face on the official DVS test. We also provide immediate feedback on each response so you learn efficiently without waiting until the end for corrections. Once you receive your TSA results and feel prepared from the practice, you’ll drive on Minnesota’s snowy highways or by one of its magnificent lakes to the DVS with the necessary documents, pay the fees, pass the test, and start the next level of your career.

A great program to prepare for the Hazmat written test.
I got 100% correct, the examiner said he couldn't recall ever seeing someone get 100% on this test. I spent about an hour a day for 5-6 days on the practice tests, videos, and reading the CDL manual for Hazmat. Key for me was doing both the practice tests and reading the manual at the same time - very helpful in understanding exactly what the questions were looking for. Great program.

This online course will more than adequately prepare you for any Hazmat test.
Been a professional driver for some time now and finally decided to add the Hazmat endorsement. I opted for the 7 day online course which was plenty of time for me. I was able to download the study book and took notes as I watched the video. It was nice to do at my own pace. Went though a series of multiple choice test questions after studying and after passing my final test, they automatically send out your certificate and I also was able to print out my certificate.

The course is excellent.
By the time I got through the 5 practice exams I knew I got this. I passed Hazmat and Tanker endorsement written the first time with 100%. I passed both written exams. So overall I am very pleased with driving-tests.org and will recommend them and use them again for future endorsements.

Cdla Hazmat Training.
I needed a refresher to renew my hazmat after letting it lapse 5 years ago. Not only did I get a refresh, driving-tests.org helped me ace my written test! The individual test prep, funny hints and ease of using this format is incredible! It's really simple, put in the work of studying and once you've completed all your curriculum, they send your info to FMCSA. Thank you for this platform!

This is the only thing you need!
I've used this program everytime I need to add or upgrade and passed every time. I only had 7 days when I found out I needed a ELDT certificate for Hazmat, and was going for Doubles Triples, Tanker, and Hazmat. I passed all three with only 2 wrong answers. I recommend this to anyone doing anything with your CDL or DL.

With only a couple of hours of studying..
With only a couple of hours of studying and practice testing I got my tanker, doubles triples, and Hazmat endorsements. I passed each test at DOT office in 5-6 min. Well worth the cost of premium membership because my endorsements will immediately make me more money.

I used the site for my hazmat ELDT….
I used the site for my hazmat ELDT Certificate. I kept taking the practice exams and marathon test until I was getting 96%. About 2 days I got my Hazmat Cert. Next day I passed my Hazmat test with 100%.

Helped me a LOT. Passed first time testing!
So far I really really like this website and what they offer. I hate test and studying, but this website helped me out in such a huge way. I have recently passed the cdl general, air brakes, and combination to obtain my permit. my score was 97% all because of using this service. It will help you so much to pass your test. I look forward to getting my Hazmat and tanker endorsement as well.
