MI CDL HazMat Practice Test 3 2025

The U.S. government has deemed certain cargo as hazardous, requiring a special endorsement to legally transport these goods. The Hazardous Materials (HazMat) endorsement allows you to legally transport specialized and often higher-paying loads. As such, adding this endorsement to your Commercial Driver’s License (CDL) in Michigan is one of the fastest ways to expand your job opportunities and increase your earning potential.

In the Great Lakes State, hazardous materials like petroleum products, industrial and automotive chemicals, agricultural products, and even explosives used in construction and mining require HazMat-endorsed drivers. Major Michigan employers, such as Ford Motor Company (Dearborn), General Motors (Detroit), Stellantis (Auburn Hills), Marathon Petroleum (Detroit), Dow Chemical (Midland), and BASF (Wyandotte), rely on drivers with Hazmat endorsements for their cargo transport needs. These industries and organizations are just some of the opportunities completely closed off to drivers without the endorsement.

Because of the heightened safety needs, a minimum age of 21 is required, and earning the endorsement includes three major milestones. First, you must complete all Entry-Level Driver Training (ELDT) requirements. Second, you’ll need to complete a mandatory fingerprinting and background check with the Transportation Security Administration (TSA). We purposely placed this requirement ahead of the final testing requirement because TSA results may take weeks to arrive. Use that time to prepare for the third and final milestone: the SOS HazMat Knowledge Test.

The HazMat Knowledge Test requires a minimum score of 80% to pass. The test covers federal regulations, hazardous material handling, packaging, quantity limits, and transport configurations (Michigan CDL Handbook 2025). With three major milestones and a substantial list of tested material, you might feel a bit intimidated. Don’t be! Our experts have created online practice tests that focus only on the material you’ll actually encounter on the exam. Additionally, each response you provide is met with immediate feedback, providing the reasons one response is correct and others are not. That real-time feedback enables you to learn as you go instead of being inundated with an end-of-exam evaluation. And, if that wasn’t enough, in addition to this practice test, we have an entire series of Michigan-specific HazMat practice tests.
