CDL Requirements in Montana (2026): Steps, Cost & Testing

Source review dated July 20, 2026 against Montana Motor Vehicle Division (MVD) — Department of Justice

Montana issues CDLs through the Motor Vehicle Division of the Department of Justice. You hold a regular Montana license, complete ELDT, pass the CDL written test for a Commercial Learner Permit, hold it 14 days, then take a three-part driving demonstration in a vehicle you supply — at a driver license station by appointment, or through Helena College. Fees are age-tiered and low (about $42 for an interstate CDL), and the CDL term maxes out at 4 years.

This guide combines federal rules with dated state research. Read the review notes before paying fees or booking a test.

State fees run about $41.72 for a 4-year interstate CDL (or $35.54 intrastate) for ages 21–71, with testing and admin included — no separate per-test charge. Montana's real cost advantage is training: the state Department of Transportation offers free ELDT, so what would be several thousand dollars of tuition elsewhere can cost little or nothing here. Hazmat still adds the separate TSA background-check fee.

Testing is by appointment at a driver license station, with a college testing option through Helena College. Montana also runs every CDL and CLP application through the federal Drug & Alcohol Clearinghouse, and qualifying veterans can skip testing entirely through the Military CDL Even Exchange.

Eligibility and documents in Montana

• Age: at least 18 for intrastate driving; 21 to drive interstate or haul hazmat.
• A valid Montana driver license (if you already hold one)
• Proof of authorized presence in the U.S.
• A valid medical examiner's certificate, if your self-certification category requires one
• For out-of-state CDL transfers: your valid out-of-state CDL, proof of identity, proof of Montana residency, and Social Security number
• REAL ID document set if you want a REAL ID-compliant CDL

How to get your CDL: step by step

1. 1

   Check eligibility, documents, and medical qualification

   Choose the CDL class and endorsements for your vehicle. Hold the required regular license and bring Montana identity, residency, and Social Security documents. Self-certify your operating category and complete a DOT physical before the permit if that category requires medical certification.

2. 2

   Pass the knowledge tests and obtain your CLP

   Take general knowledge and the vehicle/endorsement tests that apply. ELDT theory may be taken earlier, but federal rules do not require it before the CLP. A first-time hazmat applicant must complete hazmat theory before the hazmat knowledge test; hazmat is not issued on a CLP.

3. 3

   Complete required training and practice during the permit hold

   Hold the CLP for at least 14 days before the skills test. Use a qualified supervising driver for public-road practice. First-time Class A/B, B-to-A upgrades, and first-time P/S endorsements require applicable theory and behind-the-wheel ELDT from registered providers. The appropriate CLP is needed for public-road training. State training requirements may add to the federal baseline.

4. 4

   Pass the skills test in the right vehicle

   Confirm ELDT completion is recorded, arrange the test and a representative vehicle, then complete vehicle inspection, basic control, and road driving. The vehicle and transmission you test in can restrict your license.

5. 5

   Complete issuance and maintain your qualifications

   Pay the applicable Montana issuance fees and confirm the correct class, endorsements, restrictions, and expiration. Keep your medical status current when required and follow the agency’s renewal instructions.

Medical certification in Montana

At application, self-certify as Non-Excepted or Excepted and as Interstate or Intrastate. Non-excepted drivers must get a valid medical examiner's certificate from a provider on the National Registry, and the examiner uploads it electronically to the FMCSA registry (consistent with the federal National Registry II model — the June 23, 2025 electronic-transmission change). Montana's 'Manage Your CDL Online' service lets you view your medical and TSA background-check status and downgrade your CDL. An intrastate-only Montana Medical Card (MMC) alternative also exists.

If your card lapses: If a valid medical certificate is not on file with the FMCSA registry, an interstate CDL is downgraded and an intrastate license is marked 'Not Certified' (commercial privileges invalid until a valid certificate is submitted). Excepted drivers follow a defined exception checklist and need no medical card.

Every CDL holder must self-certify one operating category. The categories offered here:

• NI — Non-excepted Interstate (medical card required)
• EI — Excepted Interstate
• NA — Non-excepted Intrastate (medical card required)
• EA — Excepted Intrastate

What a CDL costs in Montana

These are separate transaction types, not charges that every applicant pays. Renewal, replacement, endorsement, and retest fees are alternatives or extras. Amounts are from the dated research; check current official fees before paying.

Montana's fees are among the lowest and are age-tiered ($41.72 interstate / $35.54 intrastate for ages 21–71, more with REAL ID). No separate written- or skills-test fee is published. Hazmat adds the separate TSA Security Threat Assessment fee (set by TSA, not Montana). A big cost advantage: Montana DOT offers free ELDT, so training can be little or no out-of-pocket cost.

See the full national breakdown on our CDL cost guide.

Skills testing in Montana

Testing access: State / approved third parties. Official testing instructions.

Montana allows approved third-party testers to administer the CDL skills test, with availability and fees set by the provider. Wait times depend on appointment availability at your station; Montana does not publish official queue figures.

Your 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.

Endorsements available in Montana

Montana offers the standard federal endorsements. Adding one usually means an extra knowledge test (and a skills test for passenger and school bus). Tap an endorsement for the full federal process and cost:

• HHazmat — 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.
• NTanker — Tank vehicles (aggregate 1,000+ gallons).
• XHazmat + Tank — Combined hazmat + tank (the standard federal combination; Montana's page describes hazmat and tank separately).
• PPassenger — Passenger (vehicles designed for 16+ including the driver); ELDT required for first-timers.
• SSchool Bus — School bus; also requires the Passenger (P) endorsement; ELDT required for first-timers.
• TDoubles/Triples — Doubles/triples.

CDL disqualifications

Disqualifying offenses are set by federal law (49 CFR 383.51) and apply in every state. Some also apply in a personal vehicle; vehicle-specific conditions matter. Montana applies the federal 49 CFR 383.51 disqualification framework. Two current Montana operational notes: beginning October 15, 2024, MVD runs every CDL and CLP application through the federal Drug & Alcohol Clearinghouse and denies (or downgrades) applicants under a driving prohibition until they complete return-to-duty; and as of early 2026 MVD temporarily halted non-domiciled CDL services pending FMCSA final-rule compliance (when resumed, limited to H-2A/H-2B/E-2 status, in person, with SAVE verification each transaction).

The offenses that trigger a disqualification, the length of each, and the federal exceptions are listed once in our CDL disqualifications guide instead of repeating the table here. Check the review notes for any Montana-specific additions we could not confirm.

Military skills-test waiver

Check the temporary July 30–October 29, 2026 federal eligibility extension and ask the state whether it participates.

Montana offers a 'Military CDL Even Exchange': a qualified service member can apply for a CDL without skills testing (and the knowledge tests may also be waived), certified by their commanding officer, typically before discharge. Eligibility requires being currently licensed and employed full-time within the last 12 months operating a military vehicle equivalent to a CMV. School bus, passenger, and hazmat endorsements cannot be transferred through the exchange.
