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

Requirements verified 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.

Montana handles CDLs through the Motor Vehicle Division of the Department of Justice. The process follows the federal pattern — a regular Montana license first, ELDT training, the CDL written test for a Commercial Learner License, a 14-day hold, then a three-part driving demonstration. Two things set Montana apart: fees are age-tiered and unusually low, and the CDL term tops out at 4 years rather than the longer terms some states offer.

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. Get your Commercial Learner's Permit (CLP). Pass the required knowledge tests: General Knowledge (all applicants); Combination Vehicles (Class A); Air Brakes (if your vehicle has them); Any endorsement tests you need (P, S, H, N, T).
2. Complete ELDT training. For a first Class A/B CDL or a first hazmat, passenger, or school-bus endorsement, you must train with a provider on the FMCSA Training Provider Registry. Montana verifies ELDT completion through the FMCSA Training Provider Registry before administering the CDL skills or hazmat knowledge test. The state's page cites a Montana ELDT compliance date of November 13, 2023 (the underlying federal rule took effect February 7, 2022). The Montana Department of Transportation offers free ELDT (31 theory modules plus behind-the-wheel), which can make training low-cost or free. Drivers who held a valid CDL or the relevant endorsement before the ELDT requirement are grandfathered.
3. Hold your permit 14 days. Federal rules require at least 14 days before the skills test.
4. Pass the skills test. It has 3 parts: Pre-trip vehicle inspection, Basic control skills, On-road driving test. 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.
5. Get your CDL issued. Pay the license fee, submit your medical self-certification, and receive your license (valid 4 years). Montana's CDL term maxes out at 4 years (ages 21–71); it is shorter for under-21 intrastate holders (tied to reaching 21) and for ages 72–74. Fees are age-tiered — a 4-year interstate CDL is $41.72 ($67.47 with REAL ID). The skills-test retest rule: fail the pre-trip or basic control and you wait at least 24 hours; pass those but fail the road test and you wait at least a week.

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

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.

Skills testing in Montana Third-party testing allowed

Montana allows approved third-party testers to administer the CDL skills test, which can mean shorter waits than a state office. 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 — including offenses in your personal vehicle. 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).

Military skills-test waiver

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.
