The business is starting, changing hands or changing what it does, and the policy has to describe it

Change of ownership insurance

A buyer taking over a business's vehicles cannot rely on the seller's auto policy without the insurer's written consent, under ISO's IL 00 17 common policy conditions. Condition F of IL 00 17 11 98 says the policy's rights and duties "may not be transferred without our written consent," and the seller's own form governs where it differs. FMCSA's FAQ of May 23, 2023 says USDOT numbers are not transferable while MC numbers are. For a purchase of the company itself, FMCSA's FAQ of May 20, 2023 keeps the USDOT number of a company that continues as the same legal person, and Utah Code 31A-21-105(4) treats a representation left uncorrected after circumstances change as misrepresentation.

Does the insurance transfer when you take over a business with vehicles?

Rights under a seller's auto policy move to a buyer only with the insurer's written consent, under condition F of ISO's IL 00 17 11 98 conditions. Condition F says "Your rights and duties under this policy may not be transferred without our written consent except in the case of death of an individual named insured," and ISO's CA 00 01 11 20 Business Auto Coverage Form says "you" and "your" "refer to the Named Insured shown in the Declarations." A different company buying the seller's vehicles is not the named insured on the seller's policy. A carrier's policy may carry a later edition or its own conditions, so the seller's declarations and forms list decide.

What changes depends on what the buyer buys: the vehicles and the operation, or the company that holds the policy, the USDOT number and any authority.

What happens to the seller's policy and vehicles at the change of ownership?

In an asset sale the seller's policy still names the seller, and IL 00 17 condition A lets the seller cancel by written notice. ISO's IL 00 17 11 98 says "The first Named Insured shown in the Declarations may cancel this policy by mailing or delivering to us advance written notice of cancellation."

For the vehicles, Utah Code 41-1a-703(1), effective January 1, 2025, requires the buyer, "before operating or permitting the operation of a transferred vehicle on a highway," to present the endorsed title and registration and apply for a new title and registration, except where Utah Code 41-1a-223, 41-1a-520 or 41-1a-704 permits otherwise.

Where the seller held a federal filing, 49 CFR 387.313T(d) bars cancelling or withdrawing it until 30 days after FMCSA receives written notice on the prescribed form, the BMC-35, and 387.313T(e) ends a retiring insurer's liability on the effective date of a replacement certificate that FMCSA accepts.

Can you change ownership of a DOT number or transfer an MC number?

A USDOT number cannot be transferred to a buyer, while FMCSA's FAQs say an MC number can move to the buyer of an entire operation. FMCSA's FAQ on transfers, last updated May 23, 2023, answers "No, USDOT Numbers are not transferable" and adds "Operating authorities (MC numbers) are transferable." Its FAQ on legal name and form of business, last updated May 20, 2023, says USDOT numbers "are assigned to only one person and remain assigned to that person forever" and "Each separate and distinct person must have separate registration."

FMCSA records an authority transfer rather than approving it. Its ownership-change FAQ, last updated May 22, 2023, says "New entities must apply for their own operating authority," that in a corporate purchase of an entire operation the seller "may instead choose to transfer its existing operating authority to the new entity," and that FMCSA discontinued the Part 365 Subpart D review and approval process in 2013. eCFR still prints Subpart D and marks the unsuffixed 49 CFR 365.405 transfer-reporting rule suspended indefinitely since November 17, 2023. FMCSA records the transfer when both seller and buyer notify it, and a seller that stops all transportation operations "should also submit an MCS-150 out of business notification."

A transferred authority is inactive until the buyer's own insurance is filed. The same FAQ says "Transferees will receive a letter in the mail instructing the recipient company to submit" proof of insurance and a BOC-3, and the authority shows as Inactive until both are met; 49 CFR 387.313T(c) requires the filing "in the full and correct name" of the person holding the authority. That FAQ predates FMCSA's May 2026 move to Motus, whose company-account job aid lists legal name changes among pending applications and, as of October 12, 2026, names no transfer step.

What policy does the new owner need from the closing date?

Utah Code 31A-22-304 sets the floor for the buyer's policy, and 49 CFR 387.9 adds a federal floor for a for-hire interstate buyer. Utah Code 31A-22-304(2) sets $30,000 per person, $65,000 per accident and $25,000 for property damage, or a $90,000 single limit, on any policy issued or renewed on or after January 1, 2025. FMCSA's 49 CFR 387.9 sets $750,000 for a for-hire carrier of non-hazardous property in interstate commerce with a vehicle of 10,001 lb GVWR or more; 49 CFR 390.5T defines a for-hire carrier as "a person engaged in the transportation of goods or passengers for compensation."

For a buyer that already holds a business auto policy, ISO's CA 00 01 11 20 covers autos acquired mid-term for the rest of the policy period under symbols 1 to 6 or 19, and under symbol 7 only if the insurer already covers all owned autos for that coverage or the auto replaces one, and the insured asks for coverage "within 30 days after you acquire it."

A buyer of the company itself answers to the representations on the company's application. Utah Code 31A-21-105(4) says "Failure to correct within a reasonable time any representation that becomes incorrect because of changes in circumstances is misrepresentation, not nondisclosure," and 31A-21-303(2)(a) lets an insurer cancel mid-term for "substantial change in the risk assumed" unless it should reasonably have foreseen the change. Neither IL 00 17 11 98 nor CA 00 01 11 20 addresses a change in who owns the Named Insured, so the company asks its insurer in writing whether the new ownership needs a notice or an endorsement.

What do you send to insure a business you are buying?

A business purchase starts with one list: who is buying, what the seller carried, the vehicles, the drivers, the registration numbers and the closing date. Text the list below to Redoubt; the first reply is a conversation about the policy the buyer needs at closing, what can be bound now, what needs the carrier and what to send back.

  • The closing date, and the buyer's legal name, entity type and FEIN
  • The seller's declarations page, and its loss runs if the insurer asks for them
  • Each vehicle and trailer: year, make, model, body type, value and VIN, and who will hold the title after closing
  • USDOT number, and MC or docket number, if any, with the power unit and driver counts on FMCSA's record, and whether the company keeps its USDOT number or the buyer registers its own
  • Every driver: name, date of birth, licence number and class
  • What the business does, what the vehicles carry, and how far they go

Frequently asked questions

What happens to the insurance and authority when an individual owner dies?

ISO's IL 00 17 11 98 condition F passes an individual named insured's rights and duties at death "to your legal representative but only while acting within the scope of duties as your legal representative." For authority, 49 CFR 365.413T(a)(3) covers "A transfer of operating rights from a deceased or incapacitated spouse to the other spouse" by letter or Form MCSA-5889. Neither text addresses another relative taking over.

Is there a change of ownership endorsement?

ISO's IL 00 17 11 98 names none. Its condition B lets the first Named Insured change the policy's terms "with our consent" by an "endorsement issued by us," and its condition F bars transferring the policy's rights and duties without the insurer's written consent.

Talk to Redoubt

Buying a business with vehicles starts with the closing date and the vehicle list

Text Redoubt the closing date, the buyer's legal name, entity and FEIN, the seller's declarations page and, if the insurer asks, its loss runs, the year, make, model, body type and value of each vehicle and trailer, every driver's name, date of birth and licence number, the USDOT and MC numbers if any, a paragraph on what the business does, and the date cover has to start, and the first reply is a conversation about the policy the buyer needs at closing.

This is general insurance information, not legal advice or a coverage determination. The policy forms, the endorsements the carrier issues, and the requirement in writing from whoever is asking control.
