TL;DR: Montana requires no operating certificate for general intrastate freight after repealing its property-carrier classes. The PSC licenses regular-route carriers, garbage haulers, household goods, and network carriers with MV-4 and MV-2 insurance endorsements, while MDT Motor Carrier Services handles weight fees, IRP, IFTA, and oversize permits.
Is there operating authority for Montana freight carriers?
Not for general freight. Montana's motor carrier statute once divided for-hire trucking into certificate classes, but the property-carrier classes were repealed, and current law recognizes only Class A regular-route carriers operating between fixed termini under regular rates, Class D garbage haulers, and Class E transportation network carriers. A flatbed, grain, livestock, or van operation hauling between Montana points needs no certificate from the Public Service Commission, no state insurance filing, and no docket number. The deregulation shifted verification to the market, where brokers and shippers check federal filings and certificates instead.
What does the PSC still license?
The remnant classes, through applications the commission publishes: certificates of compliance for regular-route and passenger operations, convenience-and-necessity applications for household goods and garbage service, and the Class E framework for network carriers added in 2021. Insurance for these classes is evidenced by the MV-4 casualty insurance endorsement and, where cargo coverage applies, the MV-2 cargo endorsement, alongside the uniform motor carrier certificates. Annual reports keep the licenses current, and temporary authority options exist for applicants awaiting full grants.
What credentials does every Montana truck need?
The working paperwork runs through MDT Motor Carrier Services: gross vehicle weight fees, IRP registration and IFTA fuel accounts for fleets crossing borders, and the oversize and overweight permits Montana's ag and equipment freight uses constantly. Seasonal load restrictions follow the spring thaw on secondary roads, and the state's permitting rules cover the escort and travel-time conditions for the biggest moves. None of this is operating authority; all of it is mandatory infrastructure for running trucks.
| Operation | State requirement | Insurance evidence |
|---|---|---|
| General intrastate freight | None, deregulated | Market driven |
| Garbage service | Class D PCN | MV-4 endorsement |
| Regular-route and passenger | Class A certificate | MV-4, MV-2 as applicable |
| Network carriers | Class E certificate | Per PSC rules |
| Interstate freight | FMCSA registration | BMC-91X or MCS-90 |
What filings do interstate Montana carriers make?
The federal set: FMCSA registration with a USDOT number and operating authority, a BOC-3 process agent designation, and insurance evidence filed directly by the insurer at the federal tiers. Unified Carrier Registration applies annually. Montana's geography makes this the default path, since regional lanes cross into five states and a Canadian province, and a carrier whose business is nominally local often discovers its through freight makes it interstate in law. The federal filing lapses trigger revocation proceedings, so insurer changes need the replacement filing posted before the old one cancels.
Why does the missing authority layer still matter?
Because it moves the burden of proof. With no state record of insurance for general freight, a Montana carrier's own certificate history, federal filing status, and safety scores are what brokers audit before tendering loads, and what opposing counsel examines after a crash. The deregulated environment rewards carriers who maintain the discipline a regulator would have imposed: continuous coverage, documented limits, and clean filings wherever filings still exist.
What should carriers take away?
Sort your operation into the right lane first: general freight needs MDT credentials and market-standard insurance, the PSC classes need their certificates and endorsements, and anything crossing a border needs the federal registrations. Keep the MDT accounts current, calendar the UCR and IRP renewals, and treat insurance continuity as the asset the missing state filing no longer protects. Montana took the gatekeeper away; the carriers that prosper act as their own.
Real questions Montana owner-operators and fleet managers ask
Does a Montana general freight hauler need a PSC certificate?
No. The property-carrier certificate classes were repealed, so general intrastate freight operates without PSC authority or state insurance filings. Only regular-route, garbage, household goods, and network carriers still license through the commission.
What is a Class D carrier in Montana today?
A garbage hauler. Current law reserves Class D for vehicles transporting garbage, licensed through convenience-and-necessity applications with MV-4 casualty insurance endorsements filed in support.
What state paperwork does every Montana truck still need?
MDT Motor Carrier Services credentials: gross vehicle weight fees, IRP and IFTA for border-crossing fleets, and oversize or overweight permits for the big ag and equipment moves, plus UCR for interstate carriers.
How do brokers verify a Montana carrier without state filings?
Through the federal system and the carrier's own records: FMCSA filing status, safety scores, and certificates of insurance. Deregulation moved the audit from the state to the market.
When does a Montana carrier need federal authority?
The moment any load crosses a state or provincial line, including through freight. Regional geography makes federal registration the practical default for most working Montana fleets.
