New authority truck insurance: what must be in place before your MC number goes active

New authority truck insurance is the primary liability policy, with its FMCSA filing, that a first-time carrier needs before FMCSA will grant operating authority. Once your application is published in the FMCSA Register, your insurer has 20 days to file proof of coverage. Cargo and physical damage are usually added because brokers and lenders ask for them.

The short version

  • FMCSA grants authority only once the minimum liability is on file, filed by your insurer on Form BMC-91 or BMC-91X.
  • For general freight in a truck rated 10,001 lb or more, the minimum is $750,000.
  • A process agent designation (Form BOC-3) and, after approval, UCR registration are separate steps. Neither one is insurance.
  • A new carrier has no loss history or safety record yet, and underwriters price that in. Prepare a complete, consistent file.

Who needs a new authority, and why insurance decides when it starts

You need operating authority (an MC number) in addition to a USDOT number if you haul regulated property for compensation across state lines. FMCSA says private carriers hauling their own cargo, and for-hire carriers that exclusively haul exempt commodities, do not need it.

The insurance link is direct. FMCSA's insurance filing requirements say the agency "will not grant operating authority registration until the registrant has in effect the minimum levels of financial responsibility on file with FMCSA." So the date your authority can become active depends partly on when your insurer files.

If you are deciding between your own authority and leasing onto a carrier first, our owner-operator truck insurance guide compares both setups line by line.

The steps, in order

  1. Get your USDOT number. An interstate carrier must file the Motor Carrier Identification Report (Form MCS-150) before it begins operations. FMCSA is moving registration to a new system called Motus; use the system FMCSA points you to on the day you apply.
  2. Apply for operating authority. The application is published in the FMCSA Register. That publication date starts the clock.
  3. Have your insurer file within 20 days. If the required insurance forms are not filed within 20 days of publication, FMCSA serves a decision saying the application will be dismissed unless you comply within 60 days.
  4. Designate a process agent. FMCSA says Form BOC-3 must name an agent for each state in or through which you operate, and that only a process agent can file it on behalf of a carrier. A post office box is not accepted as an agent's address.
  5. Check the MCS-90. Your liability policy must carry the MCS-90 endorsement. Ask for a copy and keep it at your principal place of business, as 49 CFR 387.7 requires.
  6. Register with UCR. Carriers with a federal MC number register with the Unified Carrier Registration Plan. It is a fee, not insurance. The UCR fee brackets put an operation with 0 to 2 vehicles at $46 for 2026 and $55 for 2027 (2027 fees took effect October 1, 2026).
Watch out

The name and address on your insurance filing must match your authority application exactly. FMCSA says any deviation "results in the delay of granting of the authority". Abbreviations, a missing "LLC" or an old address are enough to cause one.

Which limit applies to your first policy?

The federal minimum depends on the truck's weight rating and what you haul. These are the amounts that apply to for-hire property carriers with operating authority:

Your operationMinimum liabilityFiling form
Nonhazardous property, every vehicle under 10,001 lb GVWR$300,000BMC-91 or BMC-91X
Nonhazardous property, 10,001 lb GVWR or more$750,000BMC-91 or BMC-91X
Oil and other hazardous materials not in the $5M tier$1,000,000BMC-91 or BMC-91X
Bulk hazardous substances, explosives, poison gas, highway-route-controlled radioactive materials (see the full 387.9 list)$5,000,000BMC-91 or BMC-91X
Household goods, 10,001 lb or more$750,000 plus cargoBMC-91/91X and BMC-34 or BMC-83

A surety bond (Form BMC-82) is also accepted in place of the insurance filing. The detailed hazmat tiers and the state rules for intrastate work are on our motor carrier insurance requirements page.

The minimum is only what FMCSA requires. Many broker-carrier agreements ask for more, so read the agreements you plan to sign before you pick a limit. Cargo coverage, which motor truck cargo insurance explains, is set the same way: by the contract, not by FMCSA, unless you move household goods.

Why the first year is priced differently

We have not found any official figure for how much more a new authority pays, and we do not repeat the percentages circulating on agency sites. What can be said is why underwriters treat a new carrier differently:

  • No loss history under your name. HUB International, a broker, says underwriters review CSA data together with loss history, years in operation and fleet size to build a risk profile. A new carrier has zero years in operation by definition.
  • Little safety data. FMCSA's Safety Measurement System uses roadside inspections and crash reports from the last two years. A new USDOT number has little or nothing in it yet, good or bad.
  • Your own record still counts. Insurers list driving history among their rating factors, so your experience as a driver matters even when the company is new.

The general price factors (radius, cargo, state, truck age) are covered in semi truck insurance cost. If you have been turned down because of your record, see high risk truck insurance.

How to prepare your file before asking for quotes

A new carrier gets compared on paper. A complete and consistent file makes quotes comparable and avoids the name mismatch that delays authority. Have these ready:

  • Exact legal name, business address and entity type, as on your FMCSA application.
  • USDOT number and MC docket number, or the date you applied.
  • Truck details: year, make, VIN, weight rating, value; trailer details if you own one.
  • Lender name and address if the truck is financed.
  • Driver details: license, years of commercial driving, and your record.
  • What you will haul, where, and your expected radius.
  • The limits and certificate wording asked for by the brokers or shippers you plan to work with.

Our truck insurance quote checklist covers how to compare offers on the same limits, deductibles and exclusions. The coverage planner on our home page lists the lines your operation needs before you start.

Keeping the authority active after year one

The filing is not a one-time step. FMCSA requires carriers to keep proof of insurance and their process agent designation on file to avoid revocation proceedings. Two notice periods matter if you change insurers or a policy ends:

  • The policy itself can be cancelled by either side with 35 days' written notice (49 CFR 387.7).
  • The FMCSA filing cannot be withdrawn until 30 days after written notice reaches FMCSA (Form BMC-35, 49 CFR 387.313T).

When you switch insurers, the new insurer files its own proof. Progressive, for its part, says it usually issues filings within 48 hours; that is one insurer's statement, not an FMCSA timeline. Make sure the new filing is accepted before the old one ends.

FAQ

Can I buy the insurance before I apply for my MC number?

You can shop and get quotes first, and it helps: FMCSA's 20-day filing window starts when your application is published in the FMCSA Register, not when you find an insurer. The insurer then files the proof once your docket number exists. Keep the legal name and address identical on the application and the quote.

What happens if I miss the 20-day filing deadline?

FMCSA serves a decision telling you the application will be dismissed unless the required filings are made within 60 days. If they still are not on file, the application can be dismissed.

Do I need cargo insurance to get my authority approved?

For general freight, no: the federal filing is for liability. Household goods carriers are the exception and must also file cargo coverage (BMC-34 or BMC-83). Brokers and shippers, however, often set cargo requirements in their own agreements.

Is UCR registration part of my insurance?

No. The Unified Carrier Registration is a separate annual registration and fee for carriers with a federal MC number. It does not insure anything and is not filed by your insurer.
