Montana CDL Practice Test and Test Prep (2026)
Montana gives CDL tests through Montana Motor Vehicle Division (MVD) — Department of Justice. Here is what you will be tested on, which of our practice quizzes match each test, and what the skills test involves in Montana.

- Air Brakes (if your vehicle has them) — practice Air Brakes (40 questions)
- Any endorsement tests you need (P, S, H, N, T)
Permit minimum age: 18 (in-state driving) or 21 (interstate). Holding period before the skills test: 14 days. Permit validity: confirm with the agency.
Montana endorsement tests and practice
- Hazmat (H) practice
Montana notes for this endorsement
Requires the hazmat knowledge test plus a TSA fingerprint-based Security Threat Assessment. Montana is NOT a TSA self-managed state — you use TSA's HAZPRINT process (or the TSA Driver Service Center, 855-347-8371) and complete fingerprinting through IdentoGO. DOJ will not issue, renew, upgrade, or convert a hazmat CDL until TSA reports that you passed.
- Tanker (N) practice
Montana notes for this endorsement
Tank vehicles (aggregate 1,000+ gallons).
- Passenger (P) practice
Montana notes for this endorsement
Passenger (vehicles designed for 16+ including the driver); ELDT required for first-timers.

The Montana skills test
Components: Pre-trip vehicle inspection, Basic control skills, On-road driving test.
Test vehicle: You must provide a vehicle in good operating condition, currently registered and insured, that matches the class you are applying for and has seatbelts and passenger seating. You cannot take the skills test in a hazmat vehicle.
Where and how to book: Written and skills tests are given at driver license stations by appointment through online scheduling. Montana also offers CDL testing through Helena College (Missoula College/University of Montana runs a CDL program as well), so non-DMV testing options exist.
Waits and retests: Wait times depend on appointment availability at your station; Montana does not publish official queue figures.
Practice the inspection part with our pre-trip inspection guide. Research dated 2026-07-20; confirm testing details with Montana.
