Commercial Auto Insurance Certificate of Insurance (COI): The Complete NY Fleet Guide

Reviewed by Patrick, Licensed Commercial Insurance Broker, 20+ Years Experience

What Is a Certificate of Insurance for Commercial Auto?

A certificate of insurance (COI) is a standardized document that summarizes the key details of your commercial auto insurance in New York policy. It is not a policy itself and does not grant coverage to anyone. Instead, it serves as proof that your business carries active insurance with specific coverage types and limits. The standard form used across the insurance industry is the ACORD 25, maintained by the Association for Cooperative Operations Research and Development (ACORD.org).

When a general contractor, property owner, or government agency asks for your COI, they want to verify three things: that your policy is active, that your limits meet their contract requirements, and that they are protected if one of your vehicles causes damage on their project. The COI provides all of this information on a single page.

For New York fleet operators, the COI is especially important because the state has some of the highest insurance requirements in the country. NYC Department of Buildings projects, Nassau and Suffolk County contracts, and MTA work all require specific minimum limits and endorsements. A COI that does not match these requirements will be rejected, and your crew will not be allowed on site until the paperwork is corrected.

It is worth noting that a COI is a snapshot in time. It reflects your coverage on the date it was issued. If your policy changes, cancels, or lapses after the certificate was produced, the COI does not automatically update. This is why many contracts require that the certificate holder receive advance notice of cancellation, typically 30 days for non-payment and 10 days for all other reasons.

What Information Appears on a Commercial Auto COI?

The ACORD 25 form follows a rigid structure so that anyone reviewing it can find the information they need quickly. Every certificate issued by FHIA for your fleet insurance policy will contain the fields outlined below. Understanding each field helps you catch errors before they reach the requesting party and cause delays.

Each of these fields must be accurate. A single misspelling in the insured name, a transposed digit in the policy number, or a limit that falls $1 below the contract minimum can result in a rejected certificate and project delays. When you work with FHIA, our team reviews every certificate against your contract requirements before sending it out.

When Do NY Contractors Need a Commercial Auto COI?

In New York, virtually every commercial relationship involving vehicles on a work site or public roadway will require a certificate of insurance. The specific situations where you will need a COI depend on the type of work, the jurisdiction, and the contracting party. Below are the most common scenarios for NY contractors.

NYC Department of Buildings (DOB) Projects

Any contractor performing work that requires a NYC DOB permit must carry commercial auto insurance and provide a COI to the general contractor and often to the building owner. The NYC DOB does not directly collect COIs for auto insurance, but the general contractor's insurance requirements (which must satisfy DOB project standards) flow down to every subcontractor on the job. For construction projects in the five boroughs, you should expect to provide a COI showing at least $1 million combined single limit (CSL) for bodily injury and property damage, with the GC and property owner listed as additional insureds.

Nassau County and Suffolk County

Long Island projects carry their own requirements. Nassau County government contracts typically require $1 million CSL for commercial auto liability, along with the County of Nassau listed as an additional insured on a primary and non-contributory basis. Suffolk County follows similar standards. Private general contractors on Long Island often mirror these county requirements to protect themselves. If you are bidding on municipal work in either county, check the bid specifications carefully because limits and endorsement requirements can vary by project type and value.

General Contractor (GC) Requirements

General contractors are the most frequent requestors of commercial auto COIs. Before you can bring a vehicle onto any job site, the GC will want to see proof of coverage. This protects them from liability if one of your drivers causes an accident during the project. GC requirements are typically spelled out in the subcontractor agreement and may include specific limits, additional insured endorsements, primary and non-contributory language, and a waiver of subrogation. If your current commercial auto insurance cost does not support the required limits, FHIA can help you explore umbrella or excess liability options to bridge the gap.

Government Contracts: MTA and Port Authority

Working on Metropolitan Transportation Authority (MTA) or Port Authority of New York and New Jersey projects comes with elevated insurance requirements. MTA contracts regularly require $5 million or more in combined auto liability limits, which most contractors satisfy through a combination of a primary commercial auto policy and an umbrella or excess policy. The Port Authority has its own insurance manual that specifies requirements by contract tier. Both agencies require the agency itself to be named as an additional insured, and both require 30 days advance written notice of cancellation. FHIA has experience preparing COIs for these agencies and can ensure your certificate meets their exact specifications.

NYSDOT Highway Projects

Contractors working on New York State Department of Transportation (NYSDOT) highway and bridge projects must meet the department's insurance requirements, which are outlined in the contract's special provisions. These typically call for $1 million to $2 million in commercial auto liability depending on the project scope, with the State of New York listed as an additional insured. All carriers must be admitted in New York and hold an A.M. Best rating of A- VII or better.

What Coverage Limits Does Your COI Need to Show?

The limits displayed on your COI must meet or exceed the minimums required by your contract. Falling short by even a small amount will result in a rejected certificate. The table below summarizes common minimum requirements across different NY project types. Keep in mind that individual contracts may specify higher limits, so always read the insurance section of your agreement before requesting a certificate.

If your current policy limits fall below what a contract requires, you have two options. You can increase the limits on your primary commercial auto policy, or you can add an umbrella or excess liability policy that stacks on top of your primary limits. For example, if your primary policy provides $1 million CSL and a contract requires $5 million, a $4 million umbrella policy would satisfy the requirement. FHIA can quote both options and help you choose the most cost-effective path.

Additional Insured vs Certificate Holder: What's the Difference?

These two terms appear on every commercial auto COI, and confusing them is one of the most common mistakes contractors make. They serve very different purposes, and understanding the distinction will save you time and frustration.

Certificate Holder

The certificate holder is simply the entity that receives the COI document. Being listed as a certificate holder does not grant any coverage rights. It is an informational designation only. The certificate holder's name and address appear at the bottom of the ACORD 25 form. If your policy cancels or changes, the certificate holder may receive a notice (depending on the policy terms), but they cannot file a claim under your policy solely because they are listed as a certificate holder.

Additional Insured

An additional insured is a third party that has been added to your commercial auto policy through an endorsement. This gives them actual coverage under your policy for claims that arise from your operations. For example, if your driver causes an accident while working on a GC's project and the injured party sues both your company and the GC, the GC's defense costs and any settlement could be covered under your policy because they are an additional insured. This is real, substantive coverage, not just a piece of paper.

Primary and Non-Contributory

Many contracts in New York require that your coverage apply on a "primary and non-contributory" basis. This means your policy pays first in the event of a claim, and the additional insured's own insurance does not have to contribute. Without this language, both policies might share the loss, which is not what the GC or property owner wants. FHIA ensures this endorsement is in place when your contract calls for it.

Waiver of Subrogation

A waiver of subrogation prevents your insurance carrier from pursuing the additional insured to recover money it paid on a claim. Normally, after paying a claim, your carrier has the right to "subrogate" (seek reimbursement from the party that caused the loss). A waiver removes that right for the named additional insured. General contractors and government agencies in New York frequently require this endorsement. It must be added to your policy before the COI is issued, and FHIA handles this as part of the certificate request process.

For businesses that use hired and non-owned auto coverage, additional insured and waiver of subrogation endorsements work the same way and are equally important for contract compliance.

How to Request a COI from FHIA

Getting your certificate of insurance from FHIA is straightforward. We have streamlined the process so most certificates are ready within the same business day. Follow these four steps:

1. Gather your contract requirements. Before contacting FHIA, pull out the insurance section of your contract or subcontractor agreement. Note the required limits, whether additional insured status is needed, the exact legal name and address of the certificate holder, and any special endorsements (primary and non-contributory, waiver of subrogation). Having this information ready eliminates back-and-forth and speeds up the process.
2. Submit your request. You can email your request to our commercial lines team, call us at (631) 659-0189, or submit it through our online request form. Include a copy of the contract's insurance requirements if possible. The more detail you provide upfront, the faster we can issue an accurate certificate.
3. FHIA reviews and processes. Our team reviews your request against your current policy to confirm that your coverage, limits, and endorsements match the contract requirements. If anything is missing or needs to be adjusted, we contact you immediately with options. We then generate the ACORD 25 certificate through your carrier's system to ensure it is an official, verifiable document.
4. Certificate delivered. We send the completed COI directly to you and, if you authorize it, to the certificate holder. Most standard certificates are delivered within a few hours. Complex requests involving endorsement additions or limit changes may take 24 to 48 hours because the carrier must process the policy change first.

If you need COIs on a regular basis for multiple projects, ask us about setting up a standing certificate request process. Many FHIA clients who manage larger fleets use this approach to reduce administrative time.

Common COI Problems That Delay NY Projects

Rejected certificates are more common than most contractors expect, and every rejection means a delay. Here are the issues we see most frequently and how FHIA helps you avoid them.

Expired Coverage Dates

This is the single most common reason a COI gets rejected. If the expiration date on your certificate has passed, the document is worthless. This happens when contractors reuse an old certificate instead of requesting a current one, or when a policy renews but a new certificate is not issued. FHIA proactively tracks your policy renewal dates and can issue updated certificates before your existing ones expire.

Wrong Entity Names

The insured name on your COI must match the entity name on your contract exactly. If your contract is with "ABC Contracting LLC" but your policy lists "ABC Contracting Inc.," the certificate will be rejected. Similarly, the certificate holder's name must match exactly. Even small discrepancies like a missing comma or an abbreviated word can cause problems with strict compliance reviewers. Double-check both names before submitting your request.

Limits Below Contract Minimums

If your contract requires $2 million CSL and your policy provides $1 million, the COI will show the lower amount and be rejected. You cannot inflate the limits on a certificate. The numbers must reflect the actual policy limits. If you discover a gap, contact FHIA immediately so we can explore increasing your primary limits or adding an umbrella policy. Review our commercial auto insurance cost guide to understand how limit increases affect your premium.

Missing Endorsements

Contracts often require specific endorsements: additional insured, primary and non-contributory, waiver of subrogation. These endorsements must be attached to your policy before they can appear on the COI. If you request a certificate with endorsements that are not on your policy, the certificate cannot include them. FHIA reviews every request against your active endorsements and adds any missing ones before issuing the certificate, subject to carrier approval and any additional premium.

Carrier Not Admitted in New York

New York State requires that insurance carriers be "admitted," meaning they are licensed and regulated by the New York State Department of Financial Services (DFS.ny.gov). Many government contracts and large GCs specifically require coverage from admitted carriers. If your policy is written through a surplus lines (non-admitted) carrier, certain certificate holders will reject it. FHIA shops your coverage across 50+ admitted carriers including Travelers, Nationwide, Progressive Commercial, and Employers to ensure your COI will be accepted wherever you need it.
