Free Minnesota CDL HazMat Endorsement Practice Test 2025

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.
