New Authority Insurance: Cost, Requirements & Filing
New authority insurance is not optional and not something a carrier files itself: FMCSA requires proof of financial responsibility before operating authority can activate, and the insurer submits that proof directly on Form BMC-91 or BMC-91X. This guide covers what coverage is actually required, what it costs in the first year, what's optional, and how the filing works end to end.
Why FMCSA Requires Insurance Before Activation
Operating authority under 49 U.S.C. § 13901 ↗ cannot become active without proof of financial responsibility on file, set by 49 CFR Part 387 ↗. The rule exists so a carrier involved in a crash can actually pay a judgment instead of leaving the injured party to absorb the cost. The insurer files that proof electronically with FMCSA; a new authority cannot submit it directly, and cannot activate without it regardless of how complete every other filing is.

Required vs. Optional Insurance Coverage
FMCSA mandates one coverage type directly. Everything else gets required by a shipper, broker, lender, or lease-on carrier instead of by federal rule.
| Coverage | FMCSA Requirement | What It Covers |
|---|---|---|
| Primary Liability | Required | Covers bodily injury and property damage to others in a crash. This is what FMCSA verifies through the BMC-91/91X filing. |
| Cargo Insurance | Not required by FMCSA | Protects the freight itself. Shippers and brokers almost always require it before offering loads, typically $100,000. |
| Physical Damage | Not required by FMCSA | Covers collision and comprehensive damage to the truck. A lender or lessor financing the truck will require it. |
| Bobtail Insurance | Not required by FMCSA | Covers the tractor when driven without a trailer, off dispatch. Some carriers a driver leases onto require it. |
| Non-Trucking Liability | Not required by FMCSA | Covers the truck during personal use, off duty and not under dispatch. Common for owner-operators leased to a carrier. |
FMCSA Minimum Coverage by Cargo Type
These are combined single limits under 49 CFR Part 387: the total per-incident payout across bodily injury and property damage combined, not a per-person or per-vehicle cap.
| Cargo / Operation | Minimum Combined Single Limit | Filing Form |
|---|---|---|
| General freight, non-hazmat | $750,000 | BMC-91 or BMC-91X |
| Household goods (for-hire) | $750,000 | BMC-91 or BMC-91X |
| Oil (bulk) | $1,000,000 | BMC-91 or BMC-91X |
| Hazardous materials (placarded) | $5,000,000 | BMC-91 or BMC-91X |
| Passenger carriers, 16+ passengers | $5,000,000 | BMC-91 or BMC-91X |
These figures are minimums, not recommendations. A single serious crash can exceed $750,000 in claims easily, so many carriers buy $1,000,000 in coverage even when the federal floor is lower. See Truck Insurance Requirements for the full breakdown by vehicle class and operation type.
What New Authority Insurance Costs
Expect a new-authority premium well above what an established carrier pays for the same coverage. The gap narrows after the first year or two of clean operating history.
Zero months of authority is the single biggest cost driver. Rates typically drop after 12 to 24 months of clean claims.
Hazmat, tanker, and auto-hauler operations carry higher premiums than dry van because of claim severity, not frequency.
MVR violations, especially within the last 3 years, raise per-truck premium noticeably more for a new authority than for an established one.
Long-haul interstate coverage generally costs more per truck than regional or local hauling under the same limits.
Single-truck operations pay a higher per-truck rate than small fleets, since insurers spread fixed underwriting cost across fewer units.

BMC-91 & BMC-91X Filing Explained
Neither form is filed by the carrier. Both are filed electronically by the insurer directly with FMCSA.
Filed by insurers licensed as admitted carriers in the state where the policy is written. This is the more common filing for standard-market trucking insurance.
Filed by surplus lines insurers, which are unlicensed in the state where the policy is issued but authorized to write coverage there. New authorities with a rougher risk profile often end up here.
A carrier does not choose which form applies; the insurer's license status determines it. What matters to the carrier is confirming the insurer actually submitted the filing and that it shows as active in FMCSA's system before assuming the authority is ready to operate. A signed policy declaration page from the agent is not the same thing as a confirmed FMCSA filing.
Insurance Filing Timeline
Insurance can be arranged in parallel with the MC application, not after it. Waiting until the MC number is granted to start shopping for coverage adds weeks to activation.
Filed through the FMCSA Unified Registration System (URS).
Submitted in the same URS filing for for-hire interstate carriers.
Insurers can quote once the USDOT number exists, even before the MC number is granted.
Submitted electronically, referencing the pending or active MC number.
Required by statute before operating authority can activate, regardless of how early insurance was filed.
Requires an active insurance filing, a completed BOC-3, and a cleared protest period, all three together.

Common Insurance Mistakes New Authorities Make
Most of these show up in the first 90 days, before a carrier has a feel for how the filing actually works.
Get quotes as soon as the USDOT number exists. Binding coverage can happen in parallel with the MC application instead of after it.
A policy document from the agent is not the same as a confirmed BMC-91/91X filing with FMCSA. Confirm the filing shows active before assuming the authority can operate.
Overlap the old and new policy by a few days. FMCSA revokes authority the moment a filing lapses, with no grace period.
FMCSA does not require it, but almost no broker will dispatch a load without proof of cargo coverage on file.
A claim can be denied if the actual operation does not match what was declared on the application. Quote the real operation.
Most new-authority policies require 20% to 25% down before the policy binds, on top of the monthly premium.
