TL;DR: Montana general freight carriers face no state certificate, so programs build from the market standard of $1,000,000 liability plus cargo, physical damage, and workers compensation from the first employee. PSC-regulated garbage, regular-route, and household goods operations add MV-4 and MV-2 endorsement filings, and interstate work takes federal tiers.
What does Montana law actually require?
For general freight, the legal baseline is thin: liability at the registration minimums of 25/50/20, workers compensation from the first employee, and the MDT credentials, weight fees, IRP and IFTA where applicable, and permits for oversize loads. The deregulated environment means no Form E, no state liability floor for ordinary freight, and no certificate to maintain. The regulated remnant is specific: garbage haulers, regular-route carriers, and household goods and passenger operations under PSC jurisdiction evidence insurance through the MV-4 casualty endorsement, with the MV-2 cargo endorsement where cargo protection is required, and network carriers file under the Class E framework added in 2021.
What do the federal rules add?
Everything, for most working fleets. Montana's regional freight economy sends trucks into Idaho, Wyoming, the Dakotas, and Alberta constantly, and any interstate movement in vehicles over 10,001 pounds triggers the federal tiers: $750,000 for general freight, $1,000,000 for oil products, $5,000,000 for the highest-hazard cargo, evidenced by the insurer's BMC-91X filing or MCS-90 endorsement with the FMCSA. Livestock and ag exemptions ease some federal operating rules but not the insurance tiers, a distinction that trips up ranch-adjacent operations regularly.
What belongs in the liability and cargo program?
Primary liability at $1,000,000, because that is what shipper and broker contracts specify and what the federal filing certifies for interstate fleets. Motor truck cargo sized to the actual freight: grain, cattle, hay, timber, and machinery each carry distinct values and loss modes, livestock in particular needs mortality-aware terms, and reefer breakdown matters for the food freight moving through to the coasts. Umbrella layers respond to contracts above the primary, and non-trucking liability covers leased owner-operators between dispatches.
| Coverage | Requirement | Working standard |
|---|---|---|
| Auto liability | 25/50/20 registration floor | $1,000,000 CSL |
| Motor truck cargo | None for general freight | $100,000, livestock terms |
| Physical damage | Lender driven | Stated value, wildlife-aware |
| Workers compensation | First employee | State Fund or private |
| PSC classes | MV-4, MV-2 endorsements | PSC-set limits |
How does workers compensation work in Montana?
Coverage is mandatory from the first employee, and the Montana State Fund anchors a competitive market that private carriers also serve, so trucking accounts can shop rather than accept a single quote. Ranch and ag exemptions in the workers compensation statutes do not extend to trucking operations run as businesses, and owner-operator classification follows substance: a leased driver dispatched like an employee counts as one when a claim arrives. Montana's remote geography makes the medical side of workers compensation expensive when injuries happen far from care, which is one more argument for binding real coverage early.
What makes physical damage matter more here?
The loss modes are Montana-specific. Wildlife strikes, deer and elk on two-lane highways at dawn and dusk, produce steady comprehensive frequency. Mountain passes add winter accidents and chain-season wear, summer hail batters parked equipment east of the divide, and the distances mean towing, recovery, and downtime cost more than the same loss would in a dense state. Deductibles and downtime coverage deserve real thought, because the gap between a loss and a repaired truck can be measured in weeks when the nearest heavy shop is three hundred miles away.
How should a carrier sequence it?
Bind liability at the working standard and workers compensation before the first hire, stand up the MDT credentials, and add the federal filings the moment any lane crosses a border. PSC classes file their endorsements before operating. Then size cargo and physical damage to the freight and the geography, set umbrella capacity against the largest contract, and review annually as lanes and loads evolve. Montana's rules are light; its miles are not, and the program should be built for the miles.
Real questions Montana owner-operators and fleet managers ask
What insurance does Montana law require for general freight?
Only the registration minimums of 25/50/20 plus workers compensation from the first employee, since general freight was deregulated. The market standard of $1,000,000 liability is what actually moves freight.
What are the MV-4 and MV-2 endorsements?
PSC insurance filings for the remaining regulated classes: the MV-4 evidences casualty coverage and the MV-2 cargo coverage for garbage, regular-route, household goods, and similar PSC-licensed operations.
Do Montana livestock haulers get insurance exemptions?
No. Ag exemptions ease certain federal operating rules like hours of service, but the insurance tiers still apply to interstate work, and cargo policies need livestock-specific mortality terms regardless.
Can Montana truckers buy workers comp from the state?
Yes. The Montana State Fund is a competitive fund open to any employer, and private insurers also write trucking accounts, so comparing both markets is standard practice.
Why do Montana physical damage claims cost more?
Remoteness. Wildlife strikes, pass accidents, and hail happen far from heavy shops, so towing, recovery, and downtime stretch longer and cost more, which makes deductible and downtime decisions matter.
