Pass your Montana CDL permit exam with 80%+ on the first try
To obtain a CDL in Montana, you must pass three written permit tests — General Knowledge, Combination Vehicles, and Air Brakes — at the Montana Department of Motor Vehicles. Similar to a regular driver's license permit exam, these are timed, multiple-choice tests based on the official Montana CDL handbook.
All of our practice material is built from the official Montana CDL handbook and federal resources, and curated by professionals with over 10 years of experience in the commercial transportation industry. Studying with practice tests that mirror the real exam format is one of the most effective ways to pass on your first try.
On this page you'll find free practice tests for all three sections. For the full question bank and additional study features, download the CDL Help app.
What Are You Preparing For?

Most drivers choose Class A CDL. It's required for any combination vehicle over 26,001 lbs — tractor-trailers, semis, and 18-wheelers. If you're not sure, this is the safest pick.
Class A CDL
Combination vehicles over 26,001 lbs GVWR. Required for tractor-trailers, tanker trucks, flatbeds, and most long-haul jobs.
Class B CDL
Single vehicles over 26,001 lbs GVWR. Common for straight trucks, large buses, dump trucks, and box trucks.
Endorsements
HazMat, Tanker, Doubles & Triples, and Passenger are add-ons for specific job requirements. If you're unsure, you don't need them — they can be added later.

Your Path to a Commercial Driver's License
To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
Official Montana CDL Handbook
The official Montana CDL Manual covers every topic tested on the state's CDL knowledge exam — but it reads like a dense reference manual, not a structured study guide. A more effective way to prepare is with our General Knowledge practice tests. Our free Montana CDL permit practice test mirrors the format and content of the official exam and is fully up to date as of February 2026. Each practice test features 20 questions covering essential topics such as vehicle inspection, safe driving techniques, air brakes, cargo securement, driving emergencies, hazardous conditions, and Montana-specific commercial driving regulations. Unlike the official test, every practice question comes with a helpful hint and a detailed explanation of the correct answer — so you actually learn from every question you answer.
- Complete CDL regulations and Montana-specific requirements
- Safe driving techniques, vehicle inspection, and cargo handling
- All endorsement categories and testing requirements
Non-Domiciled CDL Information
Important information about non-domiciled commercial driver's licenses in Montana.
Federal regulations on non-domiciled CDLs are changing rapidly. The information below reflects the latest known state actions.
Montana has not published specific state-level details regarding the suspension or status of its non-domiciled CDL program beyond compliance with federal requirements. Under the FMCSA final rule published on February 13, 2026, eligibility for non-domiciled CLPs and CDLs for foreign-domiciled individuals is now limited to those holding specific, verifiable employment-based nonimmigrant statuses — such as H-2A, H-2B, and E-2 visa holders. Individuals under humanitarian or deferred status categories — including asylum seekers, refugees, and DACA recipients — are no longer eligible. State Driver's Licensing Agencies must verify applicant status through the SAVE database and ensure that no CLP or CDL is issued with a validity period extending beyond the applicant's authorized period of stay. Montana is expected to comply with these federal requirements. Affected drivers should contact the Montana DMV or equivalent licensing agency for the most current information.[FMCSA Final Rule]
English Language Proficiency (ELP)
Federal ELP enforcement applies to all CDL holders nationwide.
Federal ELP enforcement applies to all CDL holders nationwide. Here is how it is enforced in Montana.
Montana does not currently administer a separate state-level English Language Proficiency (ELP) test for CDL applicants. However, all Montana CDL holders are subject to federal ELP enforcement, which took effect on June 25, 2025. Under this enforcement, roadside inspectors conduct a two-step assessment: first, a conversational interview in English — no interpreters or translation tools are permitted — to evaluate whether the driver can communicate sufficiently in English; second, the driver must demonstrate the ability to read and interpret standard U.S. traffic signs. Drivers who fail either step of the assessment are placed out of service under CVSA guidelines. Montana CDL applicants should be prepared to demonstrate English proficiency during any roadside inspection or compliance review.
