FMCSA Insurance Requirements for Trucking Companies
FMCSA requires minimum public auto-liability limits — $750,000 for general-freight vehicles over 10,001 lbs, with hazmat and lower-weight tiers — plus insurer-filed BMC-91/91X proof and the MCS-90 endorsement. It does not require cargo, non-trucking liability, or physical damage; brokers demand those contractually.
If you are getting your own trucking authority, insurance is the gate you have to pass through — not the application paperwork, not the BOC-3, not the UCR. FMCSA will not activate your MC number until your insurer has filed proof of liability coverage with the agency. Understanding exactly what the federal rules require, and what they do not, saves new carriers from buying the wrong coverage and from getting their broker packets rejected.
This page maps the federal requirements in plain English: the minimum auto liability limits by vehicle class, the BMC-91 and BMC-91X filings, the MCS-90 endorsement, and — just as important — the coverages FMCSA does not require at all. Federal rules are the floor. Brokers and shippers build a second floor on top of it, and confusing the two is one of the most common and expensive mistakes new carriers make.
FMCSA Insurance Requirements at a Glance
FMCSA requires for-hire motor carriers to carry minimum public auto liability limits — $750,000 for general-freight property carriers operating vehicles over 10,001 lbs GVWR, with $1 million and $5 million tiers for hazmat and passenger operations. Your insurer must file proof with FMCSA (BMC-91/91X) and your policy must carry the MCS-90 endorsement. FMCSA does not require cargo insurance, non-trucking liability, or physical damage.
That is the entire federal picture in one paragraph, but the details matter: the limits change with vehicle weight and cargo class, the filings are made by your insurer rather than by you, and the MCS-90 endorsement is a specific attachment with real legal meaning. The rest of this page unpacks each piece so you can verify your own situation against the official sources — FMCSA Licensing & Insurance and the SAFER system — before you rely on any of it.
Auto Liability Minimums by Vehicle Class and Cargo Type
FMCSA sets its minimum public liability limits on a schedule that depends on what you haul and what you drive. The schedules are published by FMCSA and are the numbers your insurer's filing must satisfy. Always verify the current figures with FMCSA Licensing & Insurance before relying on them, because regulatory schedules can change and this page is a guide, not the regulation itself.
The practical implication: your insurance must be filed at or above the FMCSA minimum for your specific operation — hauling household goods, for example, triggers different minimums than general freight, and hazmat operations face the highest tiers. Your insurer handles the actual BMC-91/91X filing, but the responsibility to carry adequate limits is yours. When in doubt, verify the current schedule directly with FMCSA rather than relying on any summary, including this one.
What FMCSA Does NOT Require
This is the section most new carriers need most. FMCSA does not require motor truck cargo insurance — there is no federal cargo mandate for motor carriers, a fact so widely misunderstood that JackRick maintains a whole page explaining it. Your broker will still demand cargo coverage contractually before loading you, which is why cargo feels federally required in practice. It is market-required, not government-required.
FMCSA also does not require non-trucking liability, physical damage, general liability, occupational accident, or any of the other coverages in a real trucking insurance stack. Each of those exists because lenders, brokers, shippers, or plain business sense demands it. When you hear 'you need X insurance to run,' always ask whether the requirement comes from FMCSA, from a broker contract, from a lender, or from someone trying to sell you a policy. The answer changes what happens if you skip it.
Required Filings: BMC-91, BMC-91X, and MCS-90 Explained
The BMC-91 is the certificate of insurance your insurer files electronically with FMCSA proving your liability coverage meets federal minimums. The BMC-91X is its counterpart for certain self-insurance and multiple-policy situations. Without an active BMC-91 or 91X on file, your operating authority cannot be active — it is the filing that turns a pending MC number into a working one.
The MCS-90 endorsement is a federally prescribed attachment to the liability policy used for the FMCSA filing. In plain terms, it is the government's guarantee layered onto your policy: it ensures that minimum public-liability payment will be made for covered accidents regardless of certain policy exclusions or defenses the insurer might otherwise raise. It attaches to the specific policy your insurer uses for the federal filing, and it is required for regulated motor carriers. Because it is a standard federal form, its language is not negotiable — it says what it says on every policy that carries it.
Who Files What: Your Insurer Files With FMCSA, Not You
One of the most practical facts in this whole process: carriers do not file the BMC-91 themselves. Only the insurance company can make the electronic filing with FMCSA. Your job is to bind qualifying coverage with an insurer authorized to make the filing; the insurer's job is to transmit it. When filings are delayed, the delay is almost always on the insurance side — underwriting, policy issuance, or filing transmission — not at FMCSA.
This is why insurance shopping is usually the longest pole in the authority-application tent. You can file Form OP-1 and designate BOC-3 process agents in days, but binding a policy and getting the BMC-91 accepted takes as long as underwriting takes. Start insurance conversations the same week you start the authority application, not after. JackRick tracks insurance documents as part of its dispatch service precisely because lapsed or missing filings are the most common reason authorities get revoked.
New Authority: Insurance Before Active Authority
The sequence for a new MC number runs in a fixed order. FMCSA issues a pending MC number when you apply and pay the fee. Then your insurer files the BMC-91/91X, your BOC-3 process-agent designation is filed, and only after FMCSA accepts the filings does your authority go active. Until that moment, you cannot legally haul regulated interstate freight for hire.
New carriers should bind coverage during the application window so filings land promptly. That means having the truck identified — insurers price on the actual VIN, value, and garaging — and having your operation described accurately. Misstating the operation to get a cheaper quote creates a policy that can be voided when a claim hits, which is worse than paying the honest premium. The new-authority insurance cost page explains why first-year premiums run higher and how to shop them properly.
Broker Requirements vs. FMCSA Minimums — and the Compliance Checklist
Here is the two-column reality every carrier lives with. Column one is FMCSA: $750,000 liability for general freight over 10,001 lbs, BMC-91/91X filings, the MCS-90 endorsement, and nothing else. Column two is the broker and shipper market: typically $1,000,000 auto liability, motor truck cargo at contract-specified limits, additional insured endorsements, and waivers of subrogation — verified through carrier packets before you ever see a load. Satisfying column one keeps your authority alive. Satisfying column two keeps your truck loaded. You need both.
Staying compliant after activation is a maintenance job, not a one-time event. Keep this checklist: confirm your BMC-91/91X filing is active and matches your current policy; keep the MCS-90 endorsement on the filing policy; renew UCR annually; keep BOC-3 designations current; file the MCS-150 biennial update; and calendar every policy expiration so a lapse never reaches FMCSA. A single lapsed filing can trigger revocation proceedings, and reinstatement means re-filing, fees, and downtime you cannot bill for. Verify every current requirement with FMCSA Licensing & Insurance — this page explains the framework, but the official source is the authority.
Key takeaways
- FMCSA's federal floor is auto liability minimums plus filings — $750K for general freight over 10,001 lbs, with hazmat and light-vehicle tiers.
- Only your insurer can file the BMC-91/91X with FMCSA; the MCS-90 endorsement attaches to the filing policy.
- FMCSA does not require cargo insurance — brokers and shippers do, contractually, which is why it feels mandatory.
- New authority activates only after insurance filings and BOC-3 are accepted; shop insurance during the application window.
- Lapsed filings are the top cause of authority revocation — track expirations like revenue depends on it, because it does.
Questions carriers ask
What is the minimum auto liability FMCSA requires?
Per FMCSA's published schedule of limits: $750,000 for general-freight property carriers operating vehicles over 10,001 lbs GVWR; $300,000 for vehicles 10,001 lbs and under carrying non-hazmat; $1 million and $5 million tiers for hazmat depending on class and quantity. Always verify current limits with FMCSA Licensing & Insurance before relying on any figure.
Does FMCSA require cargo insurance?
No. FMCSA does not mandate cargo insurance for motor carriers — this is one of the most widely misunderstood points in trucking insurance. Most brokers and shippers, however, require it contractually before loading you, which is why it feels mandatory in practice. Market-required is not the same as federally required.
What is a BMC-91 filing?
It is the certificate of insurance your insurer files electronically with FMCSA to prove your liability coverage meets federal minimums. Carriers cannot file it themselves — only the insurer can. No active BMC-91 or 91X on file means your authority cannot be active.
What is the MCS-90 endorsement?
A federally prescribed endorsement on the liability policy used for FMCSA filings. It guarantees that minimum public-liability payment will be made for covered accidents regardless of certain policy exclusions or defenses. It attaches to the filing policy and its language is standard on every policy that carries it.
Do I need insurance before my MC authority is active?
Yes. FMCSA issues a pending MC number first; authority becomes active only after insurance filings and BOC-3 are accepted. Most carriers bind coverage during the application window so filings land promptly — insurance shopping is usually the longest part of the process.
What happens if my insurance filing lapses?
FMCSA can revoke your authority. Reinstatement means re-filing, fees, and downtime you cannot bill for. Lapsed BMC-91/91X filings are the single most common cause of revocations, which is why tracking insurance documents matters as much as buying the policy in the first place.
