What a Certificate of Insurance Does Not Prove

The form tells you not to lean on it

Certificates land in your inbox constantly. A broker sends one when you ask who covers what. Another carrier sends one before you interchange a trailer. Most people check the limits, see a number that looks big enough, and move on. The document itself says that is not enough.

The current ACORD 25 form, revised in December 2025, opens with a block of capital letters stating that the certificate is issued as a matter of information only and confers no rights upon the certificate holder, that it does not affirmatively or negatively amend, extend or alter the coverage afforded by the policies listed, and that it does not constitute a contract between the issuing insurer, the producer and the certificate holder. That is the insurance industry telling you in advance that this page is a summary, not a promise. Our guide to trucking certificates of insurance covers issuing your own. This is the other side of the desk.

The limit shown may already be spent

Under the coverage grid the form carries a footnote saying limits shown may have been reduced by paid claims, and that the limits shown are inclusive of amounts requested by the certificate holder and may not reflect policy limit amounts in excess of those requested. An aggregate that reads one million dollars is the number the policy started with, not the number left after two open files, and the page may be showing only what somebody asked to see.

Cargo is the other soft spot. The form has printed rows for general liability, auto liability, umbrella or excess, and workers compensation. It has no printed row for motor truck cargo coverage, so cargo gets typed into an open line or into the description box, which is exactly where numbers get stale and conditions get left off. There is no federal cargo minimum for general freight either. The only cargo floor in the rules covers household goods carriers at 49 CFR 387.303(c), five thousand dollars for loss on any one motor vehicle and ten thousand dollars for losses at any one time and place. Everything above that is whatever that carrier chose to buy.

Nobody promised to tell you when it cancels

The cancellation box on the modern form says that should any of the described policies be cancelled before the expiration date, notice will be delivered in accordance with the policy provisions. Policy provisions run between the insurer and its insured. You are neither.

Federal rules do set clocks, but none of them are yours. Under 49 CFR 387.7(b) cancellation may be effected by the insurer or the insured motor carrier giving 35 days notice in writing to the other. Under 49 CFR 387.313(d) the certificates and bonds sitting on file with FMCSA cannot be cancelled or withdrawn until 30 days after written notice, with that period running from the date the notice is filed. Those protect the agency and the parties to the policy. A certificate dated three weeks ago tells you only what was true three weeks ago.

The part you can verify yourself

Here is the piece most people never use. For an interstate motor carrier, financial responsibility is not a private matter. 49 CFR 387.7(d) requires the carrier to keep proof at its principal place of business, and the rule names the documents that count, an MCS-90 endorsement, an MCS-82 surety bond, or an FMCSA authorization to self insure with a satisfactory safety rating. Then 387.7(e) says that proof shall be considered public information and be produced for review upon reasonable request by a member of the public. You are allowed to ask, and a carrier that will not produce it has told you something.

The floors behind that proof come from 49 CFR 387.9. For hire carriers hauling nonhazardous property in a vehicle of 10,001 pounds GVWR or more carry 750,000 dollars. Oil listed in 49 CFR 172.101 and hazardous materials move it to one million, and certain bulk hazardous substances to five million. When a certificate and the federal record disagree, believe the federal record and go back to the agent named on the form for a straight answer about commercial auto liability limits.

Additional insured is an endorsement, not a checkbox

The form is blunt here too. If the certificate holder is an additional insured, the policies must have additional insured provisions or be endorsed. If subrogation is waived, certain policies may require an endorsement. And a statement on the certificate does not confer rights in place of that endorsement. So when a contract puts you on somebody else's policy, ask for the endorsement page, not a line typed into the description box. The same applies when you pull equipment that is not yours and trailer interchange coverage stands behind it. Hold your own certificate of insurance paperwork to the same standard.
