Montana DMV Test FAQ

In most states you can get a CDL at 18 for driving within your state (intrastate). You must be 21 to drive across state lines, carry passengers, or haul hazardous materials. Check your state's CDL manual for exact rules.

Yes. You first pass the knowledge tests to get a Commercial Learner's Permit (CLP), practice with a CDL holder in the vehicle, and in most states must hold the CLP at least 14 days before taking the skills test.

Everyone takes General Knowledge. Class A adds Combination Vehicles, and Air Brakes if your vehicle has them. Class B adds Air Brakes. Endorsements (HazMat, Tanker, Passenger, School Bus, Doubles/Triples) each add their own test - see the path picker at the top of this page.

Typically 50 questions, and most states require 80% to pass. Endorsement tests are shorter (usually 20-30 questions, same 80% bar). Your state's CDL manual lists the exact numbers.

Yes - a TSA security threat assessment (fingerprints and background check), and the endorsement must be renewed periodically. Start the TSA step early; it can take several weeks.

No. We are exam prep only: our practice tests get you ready for the state knowledge tests. Entry-Level Driver Training (ELDT) for first-time Class A/B applicants must be completed with an FMCSA-registered training provider.

Montana CDL Practice Test Guide: General Knowledge & Endorsements

Ready to test yourself? Pick a Montana CDL practice test above and start working through real questions before you ever sit down at the MVD.

Here is the part worth understanding first. The CDL General Knowledge test is 50 questions, and you need 80% to pass, meaning 40 of 50 correct. That is a federal FMCSA standard, so the number is the same in every state. This exam is also the written test for your Commercial Learner’s Permit, which means a Montana CDL permit practice test and a CDL general knowledge practice test are the same thing. Whether you are going for Class A, B, or C, you take this same written test. Your class gets decided later by the skills test and the vehicle you drive.

Montana puts its own stamp on what you actually need to be good at. This is a state of long empty highways, ranch and ag hauling, and heavy energy freight from the Bakken oil fields in the east and the coal country nearby. Out west the mountains change everything, so the Montana Commercial Driver License Manual sections on downgrade braking, gear selection, and managing your speed on a long descent deserve real attention. High wind along I-90 and I-15 and hard winters make traction, following distance, and stopping in snow more than theory. Tanker work moves fuel and water across those distances, and the ag and energy economy keeps Air Brakes and Combination Vehicles endorsements in steady demand.

The written test itself covers the fundamentals that keep you and everyone around you alive. Expect vehicle inspection, basic vehicle control, safe shifting, managing space and speed, spotting hazards early, and handling emergencies like a skid or a brake problem. Endorsements are separate knowledge tests, so if you plan to run Air Brakes, Combination Vehicles, HazMat, Tanker, Doubles/Triples, Passenger, or School Bus, study each one on its own.

Use the practice questions to find your weak spots, then go back to the manual and read those chapters slowly. Running through a sample CDL exam a few times builds the recall you need when the clock is real. When your scores hold steady above passing, schedule your CDL skills test with the Montana MVD and go earn that permit.
