What Commercial Auto Insurance Requirements Apply in Montana?

A Montana-registered vehicle operated by its owner or with permission must have continuing liability protection at least at $25,000/$50,000/$20,000, unless an authorized self-insurance or statutory exception applies. The required policy statute does not itself require protection for employee injuries at work or property in the insured’s care or transport.

What Is Commercial Auto Insurance?

Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. Read the national Commercial auto guide.

What Should You Watch for With Commercial Auto Insurance in Montana?

Match the Policy to the Registered Units
Montana’s required policy must describe the covered motor vehicles and insure the named insured and permissive users. Reconcile the schedule with the current fleet list and ask how newly acquired, replacement and borrowed units are handled. ²
Check the Employee Injury Boundary
The state minimum-policy statute says the policy need not cover employee bodily injury while the employee is working or operating, maintaining or repairing a vehicle. Ask which workers’ compensation or other policy applies to each employee exposure; do not read the liability floor as an employee benefit. ²
Do Not Treat the Auto Minimum as Cargo Cover
The same statute says a required motor-vehicle policy need not cover property owned, rented, held or transported by the insured. For goods you carry for others, ask for the separate cargo terms and limits in writing. The PSC also lists cargo filings separately from casualty filings for regulated carrier classes. ^2,³
Identify Your PSC Filing Class
Montana PSC lists separate MV-4, MV-2, TNC, Form E, Form H and Form K insurance filings. Ask the PSC or broker which filing applies to your authority class and get the insurer to file the matching form; the list alone does not make every form apply to every carrier. ³

Which Commercial Auto Providers Have Montana License Records?

These providers publish a national listing for Commercial auto; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Montana. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ²⁴

Surplus-Lines Tax and Stamping Office in Montana

Reported tax rate. 2.75% of total premium (0.75% for legal professional liability) + 2.50% fire tax on applicable fire premium + 0.175% SLIP+ transaction fee on total premium ^7,^8,^10,¹¹

Montana requires an eligible surplus-lines insurer and a statutory placement path when it is the insured’s home state. Before placement, the producing producer must advise you that the insurer is unauthorized in Montana and is not subject to the same supervision as an authorized insurer, and that if the surplus-lines insurer becomes insolvent, Montana’s property-and-casualty guaranty fund will not pay losses under the surplus-lines coverage. Confirm the applicable placement route and tax and fee bases with the producer.

Montana surplus-lines placement routes: When Montana is home state, §33-2-302 generally calls for an eligible insurer and evidence that the line or full amount is unavailable from authorized insurers (or, at renewal, has not become available). The evidence routes are a diligent search of at least three insurers actually writing that line in Montana (or the smaller actual market), the kind appearing on the current Approved Risk List, or natural-disaster multiperil coverage. The list names kinds and classes; it does not prove that a particular business or BOP qualifies. Section 302 separately waives search requirements for an authorized quote with a premium rate at least 10% above the eligible unauthorized quote, if commissioner-approved disclosure is provided; and for a qualifying exempt commercial purchaser (ECP), after disclosure that coverage may or may not be available from an authorized insurer that may provide greater protection with more regulatory oversight, followed by the purchaser’s later written request. Under §318, an ECP must employ or retain a qualified risk manager as defined in §319, have paid over $100,000 in nationwide commercial P&C premiums in the prior 12 months, and meet one additional §318(1)(c) criterion. Some financial thresholds adjust every five years. ^10,^11,^9,^13,^16,¹⁷
Check the fire-tax allocation on a commercial package: Section 33-2-311 generally requires the surplus-lines producer to collect and pay the tax when Montana is home state, subject to §33-2-323. For a single-state risk with Montana as home state, §33-2-323(4) requires submission to the Commissioner, who collects the tax. Ask the producer which filing and payment route applies. CSI’s July 2026 guide lists code 1005, Commercial Package (Property & Casualty), with a 50% presumptively reasonable allocation and a 1.25% effective fire-tax rate. Treat this as an example: verify the code and allocation used for the policy; do not assume every BOP is classified as code 1005. CSI’s current schedule sets annual tax due dates (quarterly tax payments are accepted) and separate quarterly SLIP+ transaction-fee deadlines. ^12,^15,^14,¹⁸

Commercial Auto Insurance in Montana: Frequently Asked Questions

What are Montana’s minimum motor-vehicle liability limits?

Montana’s policy statute lists $25,000 for one injured person, $50,000 for two or more, and $20,000 for property damage. Registered vehicles operated here generally need that level unless self-insurance or a statutory exemption applies. ^2,¹

Does Montana’s required auto policy have to cover employee injury or cargo?

Not necessarily. The statute says the required policy need not cover employee bodily injury while working or property owned, rented, held or transported by the insured. Ask which separate policy addresses each exposure. ²
