Insurance Before Authority: What You Need and When

Insurance is the most consequential step in the authority activation process — and the one where new carriers most often stall.

The confusion usually comes from a sequencing question: do I buy insurance before or after applying for MC authority? The answer matters, because you can’t start hauling until insurance is confirmed on file with the FMCSA.

How Insurance and Authority Activation Connect

Here’s the relationship in plain terms:

1. You apply for MC authority (Operating Authority).
2. A 21-day protest period begins.
3. During that 21 days, you must get insurance in place and have your insurer file the required forms with the FMCSA.
4. You must also file your BOC-3 during this period.
5. After 21 days pass — if all filings are confirmed — authority becomes active.

If your insurance is not on file when the protest period ends, your authority will not activate. You’ll need to wait until filings are confirmed.

Operating without active authority is a federal violation. Operating without insurance is both a federal violation and a personal financial catastrophe waiting to happen.

Minimum Insurance Requirements

FMCSA sets minimum liability coverage levels. These vary based on what you haul and how you operate. As of the most recent regulatory guidance:

Operation Type	Minimum Liability
Non-hazmat property carriers	$750,000
Hazmat carriers (certain materials)	$1,000,000–$5,000,000
Passenger carriers (various sizes)	$1,500,000–$5,000,000

These are federal minimums, not recommendations. Many shippers, brokers, and load boards require $1,000,000 in liability coverage regardless of your operation type. Budget for this in your trucking startup cost estimate.

Always verify current minimums directly with the FMCSA, as these figures are subject to regulatory change.

Coverage Types to Understand

Primary Liability — Required by FMCSA. Covers bodily injury and property damage to third parties in accidents you cause while hauling.

Cargo Insurance — Covers the freight you’re hauling if it’s damaged, lost, or stolen. Not all brokers or shippers require it, but most do. Common minimums are $100,000.

Physical Damage — Covers damage to your own truck and trailer. Usually required by lenders if you have a vehicle loan.

Bobtail / Non-Trucking Liability — Covers liability when you’re operating the truck without a trailer or when not under dispatch. Relevant for owner-operators.

General Liability — Business liability coverage beyond your trucking operations. Some shippers require it.

The MCS-90 Endorsement

The MCS-90 is a federal endorsement that your insurer attaches to your primary liability policy. It’s not a separate policy — it’s a requirement added to the one you already have.

What it does: it makes your insurer responsible for minimum federal liability amounts to the public even if a policy exclusion would otherwise apply. It protects the public, not you.

Your insurer files the MCS-90 electronically with the FMCSA as part of your insurance filing. You do not file it yourself.

The BMC-91X Filing

The BMC-91 and BMC-91X are the forms your insurance company files with FMCSA to certify that you carry the required public liability coverage as a motor carrier. They are carrier insurance filing forms — not broker forms. The BMC-91X is the standard form for property carriers.

Your insurer files the BMC-91X alongside (or as part of) the MCS-90 endorsement process. You do not submit either form yourself — your insurer handles the FMCSA electronic filing.

A note on broker insurance requirements: Freight brokers and freight forwarders operate under a separate bonding requirement — they must file a BMC-84 surety bond ($75,000 minimum) or a BMC-85 trust fund agreement with FMCSA. These are distinct from motor carrier insurance filings and are not relevant to new carrier authorities covered by this guide.

Pre-Authority Insurance Checklist

• Contact at least 2–3 insurers specializing in commercial trucking
• Get quotes based on: vehicle type, weight, commodity, radius, and driver record
• Confirm the insurer can file forms directly with the FMCSA
• Confirm coverage meets or exceeds FMCSA minimums for your operation
• Confirm coverage meets broker minimums (typically $1M liability, $100K cargo)
• Review policy exclusions carefully — some exclusions matter in trucking
• Confirm the down payment amount and monthly payment structure
• Understand what happens to your policy if you miss a payment
• Ask whether your insurer uses an insurance filing service or files directly

After You Have Insurance

• Request your Certificate of Insurance (COI)
• Verify your MCS-90 filing appears in FMCSA LMIA: li-public.fmcsa.dot.gov
• Keep a physical copy of your COI in the truck
• Update brokers with your current COI when it renews

Why New Carriers Pay More

Insurance companies view new authorities as higher risk. You have no safety history, no carrier profile, and no track record. Expect to pay more in the first 1–2 years than an established carrier with a clean record.

Factors that affect your initial insurance cost:

• CDL experience and driving record
• Type of freight (hazmat adds cost)
• Radius of operations
• Age and value of equipment
• State of operation

Building a clean safety record in your first 12–18 months will help when it’s time to renegotiate rates. The insurance down payment guide explains how that first policy can affect launch cash flow.

Common Mistakes

Not confirming the FMCSA filing. Your agent may tell you insurance is filed, but the FMCSA system is the authoritative record. Check LMIA yourself.

Buying cheap, uncompliant coverage. Some insurers offer trucking policies that don’t include the MCS-90 endorsement or don’t meet FMCSA minimums. If your insurer can’t file directly with the FMCSA, you’ll need to find a new one.

Not understanding what coverage activates when. Some policies don’t cover you while bobtailing. Others have radius restrictions. Read the exclusions before signing.

Canceling insurance before switching carriers. If your insurance lapses — even briefly — the FMCSA is notified immediately. A lapse can affect your authority status.

Frequently Asked Questions

Do I need insurance before applying for MC authority?

You do not need insurance in place before applying. However, insurance must be filed with the FMCSA and confirmed before your authority activates. The 21-day protest period provides time to arrange insurance.

What is an MCS-90 endorsement?

The MCS-90 is a mandatory endorsement added to your liability policy. It guarantees minimum insurance coverage to the public even if the insurer would otherwise deny a claim (e.g., due to a policy violation). Your insurer files it directly with the FMCSA.

How long does it take for insurance to show in FMCSA?

Once your insurer submits the filing, it typically appears in the FMCSA LMIA system within 1–2 business days. Confirm it's visible before dispatching.
