A Certificate of Insurance (COI) is a one-page document your insurance broker issues that summarizes your active coverage — carrier name, policy numbers, effective dates, and coverage limits. For auto transport operators, it is the single most-requested document on any load board, dealer lot, or auction gate. Without a current COI that meets a shipper’s minimums, you will not get the load — full stop.
This guide breaks down exactly what brokers and dealers require on a COI, the FMCSA minimums you must carry, and how to manage certificate requests so they never delay a dispatch.
What Is a Certificate of Insurance and Why Does It Matter for Auto Transport?
A COI is issued on the standard ACORD 25 form. It is not the policy itself — it does not grant coverage and cannot be altered to add coverage that does not exist in the underlying policy. What it does is give a third party (a broker, dealer, auction house, or load board) a fast way to confirm your insurance is in force without reading a 60-page policy document.
Auto transport operators face COI requests at nearly every touchpoint: when registering on Central Dispatch or Super Dispatch, when picking up a vehicle at a franchised dealership, when dropping off at an auction facility like Manheim or ADESA, and when contracting with a new freight broker. Most of these parties require you to name them as an Additional Insured on the certificate, which means their legal name must appear in Box 7 of the ACORD 25 form.
FMCSA Minimum Insurance Requirements for Auto Haulers
The Federal Motor Carrier Safety Administration sets the floor. Every interstate auto transport carrier must file proof of financial responsibility with FMCSA before operating. The current federal minimums for hauling non-hazardous freight in vehicles under 10,001 lbs GVW are set by 49 CFR Part 387. For car haulers specifically:
| Vehicle Type | Minimum Liability (Public) |
|---|---|
| For-hire motor carrier, non-hazardous cargo, vehicles >10,000 lbs GVW | $750,000 combined single limit (CSL) |
| For-hire motor carrier, non-hazardous cargo, vehicles ≤10,000 lbs GVW | $300,000 CSL |
Most full-size car carrier rigs (3-car, 5-car, 8-car) exceed 10,001 lbs GVW, so the $750,000 minimum applies. These figures are federal floors — many brokers, dealers, and load boards require higher limits in their contracts.
Separate from the liability filing (Form BMC-91 or BMC-91X), FMCSA also requires cargo insurance. The federal minimum for household goods is $5,000 per vehicle and $10,000 per occurrence, but auto transport cargo insurance requirements are set by shipper contracts rather than a single federal figure. In practice, expect most brokers to require between $100,000 and $500,000 in cargo coverage per load.
What Brokers and Dealers Actually Ask For
Federal minimums are the legal baseline. Commercial reality is higher. Here is what you will encounter on the ground:
Load Board and Broker Requirements
- Central Dispatch: Requires proof of $750,000 auto liability and $250,000 cargo at minimum to maintain a carrier listing. Some of the larger brokers posting on Central Dispatch add their own certificate requirements in the dispatch sheet.
- Super Dispatch: Carriers must upload a COI during registration. Super Dispatch verifies coverage limits match what was entered; mismatches flag the carrier account.
- Direct broker contracts: Many brokers require $1,000,000 CSL auto liability and $500,000 cargo. A few high-volume shippers (new-car logistics, OEM suppliers) require $2,000,000 or more. Read every broker agreement before signing — these figures appear in the insurance clause, usually Section 8 or 9.
Dealer and Auction Requirements
- Franchise dealerships (Ford, Toyota, GM, etc.) almost universally require $1,000,000 auto liability and name the dealership entity as Additional Insured on the COI. Some dealer groups require umbrella coverage of $1,000,000 on top of primary liability.
- Manheim / ADESA / other auction lanes: These facilities have carrier registration portals (Manheim uses Carrier411 integration). Your COI must be uploaded and current. They typically require $1,000,000 liability and will decline entry if your certificate has expired or shows limits below their floor.
- Independent dealers: Requirements vary widely — some accept the FMCSA minimum, others mirror franchise dealer standards. Always ask for the dealer’s certificate requirements before arriving to pick up.
How to Read a COI and Spot Common Problems
When your insurance broker sends you a COI, review these fields before forwarding it to any shipper:
- Effective and expiration dates: The policy period in Box 5 must cover your current operation date. A COI issued on an expired policy is worthless and will be flagged immediately.
- Coverage limits: Confirm the liability limit in Box 5 (Commercial Auto) matches or exceeds what the broker or dealer requires. Do not assume — read the number.
- Named insured: Your legal business name (the DBA or LLC on your operating authority) must appear exactly as it is registered with FMCSA. A mismatch between the COI name and your MC number registration is a red flag auditors catch immediately.
- Additional insured language: If the shipper requires it, Box 7 (Description of Operations) must contain the shipper’s legal name and the words “is named as Additional Insured.” A certificate that merely shows your coverage but omits the additional insured endorsement will be rejected.
- Cargo coverage: Cargo insurance often appears in Box 5 under “Inland Marine” or a separate cargo line. Make sure the limit shown matches your contract requirement. Some brokers want a separate cargo certificate entirely.
The most common reason a COI gets rejected is a limit shortfall — the certificate shows $750,000 but the dealer requires $1,000,000. The fix is simple: call your broker and ask them to reissue with higher limits if your policy supports it, or increase your coverage if it does not. Do not try to alter the certificate yourself — that is insurance fraud.
Managing COI Requests Without Slowing Down Dispatch
A single operator running three or four trucks can receive a dozen COI requests per month — new broker registrations, dealer pickups, load board renewals, and annual contract renewals. Handling these manually by email and phone call is a significant time sink and creates gaps when a dispatcher is on the road.
Build a COI Distribution System
- Ask your insurance broker to set you up on a certificate management portal (most major commercial carriers — Progressive, Great West, Canal, Cover Whale — offer this). You can issue COIs directly for named additional insureds without calling your broker each time.
- Keep a master COI template with your standard limits ready for common shippers. Save broker-specific COIs as PDFs named by company:
COI_ManheimAtlanta_2026.pdf. - Set a 30-day expiration reminder on your policy renewal date. Most brokers and load boards will suspend your carrier listing if your COI lapses, even for a weekend. A lapse on Central Dispatch during a busy season can cost you $5,000–$10,000 in lost loads.
- Track which shippers require Additional Insured status. This is not automatic — you must request an endorsement from your insurer for each one. Some insurers charge a small fee ($25–$75 per endorsement) and require a few days to process.
Typical COI Turnaround Times
Standard COI reissue from an insurance broker: same business day, often within the hour if you use a portal. Adding a new Additional Insured endorsement: 1–3 business days depending on the insurer. Increasing policy limits: 1–5 business days, requires underwriting approval and may trigger a premium adjustment. Plan accordingly — do not agree to a load that requires a COI modification the day before pickup.
State-Level Requirements and Intrastate Operations
If you run loads within a single state (intrastate), FMCSA authority may not apply — but every state has its own DOT equivalent with its own minimums. California, for example, requires intrastate carriers to file with the California Public Utilities Commission (CPUC) and carry at least $750,000 in liability. Texas, Florida, and Illinois have their own intrastate carrier registration programs with varying insurance floors.
The safest approach for operators who run both intrastate and interstate loads is to carry limits that satisfy the most demanding requirement across all your operating states, and to file both your FMCSA BMC-91 and any required state filings. Confirm with your insurance broker that your policy includes the state endorsements needed for every state in your operating area. A policy that covers FMCSA filings but lacks a California MCP filing will get your California intrastate loads rejected.
Putting It All Together
A COI is not paperwork for its own sake — it is the proof that lets you move vehicles, get paid, and protect your business when something goes wrong on the road. Keeping your certificates current, understanding what each shipper requires, and building a system to issue them quickly is as much a part of running a professional auto transport operation as maintaining your rigs or managing your drivers.
Operators who treat COI management as an afterthought end up with delayed pickups, suspended load board listings, and last-minute calls to their broker at 6 AM. Operators who build it into their dispatch workflow — alongside driver assignments, load tracking, and invoicing — run tighter, more profitable operations.
