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.
