Free Montana CDL Permit Practice Test: General Knowledge 2025

The great state of Montana derives much of its income from agriculture, such as the production of beef, wheat, and barley. Other key economic sectors include timber production and mining, especially the production of coal, oil, copper, and precious metals. All these sectors employ truck drivers to bring their products to market or distribution hubs. One of the state’s fastest-growing economic sectors is tourism, creating opportunities for bus drivers to transport visitors to Glacier National Park, Yellowstone National Park, and other tourist attractions and points of interest.

Major commercial routes include Interstate 15, an important route for tourism and trade with Canada, which runs from the Canadian border of Montana to southern California; Interstate 90, a major transcontinental route, which runs from Washington State to Massachusetts; Interstate 94, which runs from Montana to Michigan, where it has a direct connection to Ontario, Canada; U.S. Route 2, an important route for agricultural transport, which runs from Washington State through northern Montana and then on to Michigan; and U.S. Route 93, supporting regional trucking, which runs from the Canadian border of Montana through Idaho and Nevada and terminates in Arizona.

However, you have many steps to take and requirements to meet before you may drive on these or other roads as a licensed commercial driver.

You’re probably here because your immediate goal is to pass the official knowledge test for a Commercial Learner’s Permit (CLP), a vital credential along the way to obtaining a Commercial Driver’s License (CDL). And because you could use more help to pass the knowledge test than you’ve gotten by reading the official Montana Commercial Driver License Manual (Montana CDL Handbook 2025) a few times.

This free Montana CDL permit practice test is based on the official state manual, just like the official knowledge test. It’s up to date as of October, 2025. There are 50 multiple-choice questions on such topics as basic vehicle maneuvers, cargo management, emergency preparedness, and pre-trip inspections. Our automated assistant stands ready to assist you during the practice test with a hint and an explanation of the correct answer. Read the explanation carefully if you missed the question so you won’t make the same mistake next time. This practice test does not have a time limit. Take your time, not only to improve your chances of passing the test but also to learn as much as you can from the experience. For example, if you stumble over a question, you may want to pause the test and look up the information in the official manual before you proceed further.
