What is an MCS-90 endorsement?

MCS-90 is a public-liability endorsement attached to an applicable motor-carrier policy; it is distinct from the insurer/provider's BMC filing. It does not provide physical-damage or motor-truck-cargo insurance, and it is not an operating-authority grant. Whether the endorsement applies to a claim requires review of the regulation and facts. [1]

What are the minimum liability limits for interstate trucking?

Federal financial-responsibility minimums differ by operation, vehicle weight and commodity. The FMCSA chart lists $750,000 for a specified nonhazardous for-hire property category at 10,001 pounds GVWR or more; other categories and broker/shipper agreements may require different terms. Verify the precise category before relying on a number. [1]

What is the difference between BMC-91 and BMC-91X?

These are public-liability financial-responsibility forms filed electronically by an eligible insurer/provider for applicable authority. They are not the MCS-90 policy endorsement. A BMC-34 cargo filing applies to certain operations, including household-goods carriers—not automatically to all general freight. BOC-3 is a separate process-agent designation. [1]

What is a BOC-3 filing?

A BOC-3 designates a process agent in each state where the carrier operates — a party authorized to accept legal documents on the carrier's behalf. The FMCSA requires a BOC-3 on file before granting operating authority. It is typically filed through a blanket process-agent service rather than by the insurer. [1]

What is UCR and do I have to pay it?

The Unified Carrier Registration (UCR) is an annual federal registration and fee program for interstate carriers, brokers, freight forwarders, and leasing companies, with the fee tiered by fleet size. It is separate from your insurance filings, but lapsing on UCR can lead to enforcement just as a filing lapse can. We flag it so nothing falls through the cracks. [2]

Does Florida intrastate trucking need FMCSA filings?

FMCSA filings apply to interstate for-hire operations under federal authority. If you operate only within Florida, you generally follow Florida's financial-responsibility rules instead — Florida Statutes § 627.7415 sets combined liability minimums of $50,000 to $300,000 based on vehicle weight, and shipper contracts usually require more. We confirm whether you are interstate, intrastate, or both before assuming which rules apply. [3]

How does an authority lose its 'active' status?

A lapse or cancellation of required financial-responsibility evidence can affect motor-carrier authority. Monitor the actual FMCSA record, insurer/provider filings and notice dates. An agency can help coordinate with the authorized filer but cannot guarantee uninterrupted authority or reinstate it itself.

FMCSA Filings & Federal Financial Responsibility

The applicable authority, liability minimum, insurer/provider filing and process-agent designation are distinct. Which ones you need depends on the actual motor-carrier operation, vehicle and cargo; a pending filing is not active authority.

Quick answer

FMCSA financial-responsibility filings depend on the entity and operation. An eligible insurance provider submits BMC public-liability evidence for covered motor-carrier authority; MCS-90 is a separate policy endorsement where applicable. Some operations, including household-goods carriers, require a cargo filing. A BOC-3 designates process agents. Ellie is an insurance agency that can review the request and coordinate with the appropriate provider, not grant or guarantee operating authority.

The four pieces

Authority, limits, filings, and process agents are separate

Most carrier confusion comes from treating these as one rule. They are four independent pieces — you can have one and still be out of compliance on another.

1 · Operating authority

A USDOT number identifies the carrier; an MC docket number does not, by itself, mean the applicable operating authority has been granted.

2 · Liability minimums

Federal bodily-injury/property-damage requirements vary by vehicle weight, authority type and commodity. Check FMCSA's current chart for your operation.

3 · Insurance filings

An authorized provider submits the applicable BMC financial-responsibility filing; MCS-90, where required, is a separate policy endorsement. Cargo filings depend on operation.

4 · Process agents (BOC-3)

A BOC-3 names someone in each operating state who can accept legal service for you. The FMCSA requires it on file before authority is granted.

These pieces sit underneath every program in the trucking insurance lineup — from semi-truck primary liability to motor truck cargo.

The filings in plain English

What each FMCSA filing actually does

These federal forms have different purposes. An eligible insurance or financial-responsibility provider files applicable BMC evidence; the BOC-3 is a separate process-agent filing.

MCS-90 endorsement
Attached to applicable motor-carrier liability policies for federal public-liability financial responsibility; not first-party cargo or truck coverage and not an FMCSA filing itself.
BMC-91 / BMC-91X
Public-liability financial-responsibility evidence submitted to FMCSA by the authorized provider for the right motor-carrier entity and operation.
BMC-34
The cargo financial-responsibility filing, required for certain household-goods carriers and where otherwise mandated.
BOC-3 (process agents)
Designates a party in each operating state authorized to accept legal documents on your behalf. Required before authority is granted.
UCR registration
Annual interstate registration and fee, tiered by fleet size — separate from the insurance filings but enforced alongside them.
USDOT & MC/FF numbers
USDOT identifies the carrier for safety; the MC/FF number is the for-hire operating authority that must stay active.

Interstate vs. Florida intrastate

Which rules apply to your operation

The filings above are federal and apply to interstate for-hire carriers. Florida-only operations follow state financial-responsibility law instead — and many carriers do both.

Interstate for-hire

A motor carrier hauling regulated property for others across state lines may need federal authority, financial-responsibility evidence and process-agent designation; exceptions and category-specific rules apply.

Florida intrastate

A carrier operating solely in Florida may face state rather than federal authority requirements. Verify vehicle class, commodity, contracts and current Florida rules separately.

Mixed operations

If your business takes intrastate and interstate loads, verify each operation and contract before dispatch rather than relying on one assumed limit.

Where carriers lose authority

Common FMCSA compliance gaps

Letting a liability policy cancel — the insurer files the cancellation and the authority can be revoked
Assuming the MCS-90 is first-party coverage for your own truck or cargo (it is not)
Assuming the federal minimum automatically satisfies a particular broker or shipper contract
Hauling a regulated commodity at the general-freight minimum instead of the higher hazmat figure
Taking an interstate regulated load without checking the applicable authority and liability requirements
Missing the annual UCR registration and triggering enforcement
Relying on a pending MC docket or quote rather than verifying current authority and filing status
