Free North Dakota CDL HazMat Endorsement Practice Test 2025

Interested in adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL)? It’s a smart idea for expanding your job opportunities and increasing your earning potential! In North Dakota, you’ve likely experienced the strong winds on the flat plains and prairies, the often-flooded crossings along the Missouri River Basin, the Badlands, and the rugged terrain near Theodore Roosevelt National Park. Perhaps you’re already familiar with the gravel and unpaved roads in rural areas (particularly in farming and oil-producing regions), as well as summer tornadoes and the state’s harsh winters with heavy snow and ice. Make no mistake, transporting cargo in North Dakota has its challenges and is not for the weary, but the rewards offered in this career and the additional opportunities available with the Hazmat endorsement make it worth the effort.

The Hazmat endorsement is required to legally transport materials classified hazardous by the U.S. government. In the Peace Garden State, these materials include anhydrous ammonia (fertilizer), petroleum products, crude oil and natural gas, pesticides and herbicides, and industrial chemicals. Some prominent organizations in North Dakotathat depend on Hazmat drivers include Hess Corporation and Marathon Oil in Williston and the Bakken Formation area, agricultural suppliers like CHS Inc., local cooperatives that distribute fertilizers and chemicals, and fuel distributors like Tesoro Logistics (now Marathon Petroleum). Wow! That’s far too much opportunity to ignore. You are on the right track in seeking this endorsement.

It starts with a mandatory fingerprinting and background check conducted by the Transportation Security Administration (TSA). The second step, which you can complete while you wait weeks for the results, is to study for the DOT knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials. With a score of 80% on North Dakota’s 30-question knowledge test, you will pass the test (North Dakota CDL Handbook 2025).

Our North Dakota DOT Hazmat Endorsement practice tests are designed to simplify this process for you. We know it can be a bit daunting, so we’ve designed our practice tests to avoid unnecessary information and resemble what you will face on the official DOT test. Receiving immediate feedback on each response, you’ll learn as you go. Once you receive your TSA results and feel prepared, you’ll visit the DOT with the necessary documents, pay the fees, and pass the test.
