If you operate a trucking company, you've issued hundreds of certificates of insurance. Shippers ask for them. Brokers require them. Customers won't load you without one. But most fleet owners treat certificates as paperwork to be processed rather than documents to be understood. That's a mistake — because what your certificate says (and doesn't say) can create real problems. What a Certificate of Insurance Is A certificate of insurance (COI) is a one-page summary of your insurance coverage. It shows: - Who is insured (the named insured) - What policies are in force - The limits of each policy - The effective and expiration dates - Any additional insureds or certificate holders What it is NOT: A certificate is not a contract. It does not modify, extend, or alter your actual policy. It's a snapshot — proof that coverage exists as of the date issued. The Key Sections Producer. This is your insurance agent or broker — the company that placed your coverage. At Trux, this is where our name appears. Insured. Your company name and address exactly as it appears on your policy. If your legal name is "Smith Trucking LLC" but you operate as "Smith Transport," make sure both names are on your policy or the certificate may not satisfy the requesting party. Insurers. The actual insurance companies providing coverage. Each is assigned a letter (A, B, C) that corresponds to the coverage lines below. Coverages. This is the meat of the certificate. Each line shows: - Type of coverage (auto liability, general liability, cargo, etc.) - Policy number - Effective and expiration dates - Limits Description of Operations. Free-form text that can include specific job descriptions, contract numbers, or additional information requested by the certificate holder. Certificate Holder. The party requesting the certificate — typically a shipper, broker, or customer. Common Mistakes 1. Wrong named insured. If your certificate shows "John Smith" but your MC authority is under "Smith Trucking LLC," the certificate doesn't match your authority and may be rejected. 2. Expired certificates. Certificates have expiration dates. If you issued one six months ago and your policy has since renewed with different terms, the old certificate is meaningless. Many brokers now use automated systems that flag expired certificates. 3. Assuming "additional insured" means what you think. Being listed as an additional insured on someone else's policy gives you specific rights under that policy. Being listed as a "certificate holder" does not. These are different things with different legal implications. 4. Believing the certificate guarantees coverage. A certificate says coverage exists. It doesn't say coverage will apply to a specific claim. Your actual policy terms, conditions, and exclusions control what's covered. 5. Not matching contract requirements. If your shipper contract requires $1,000,000 in auto liability and your certificate shows $750,000, you're in breach of contract — regardless of whether a claim occurs. What "Additional Insured" Actually Means When a shipper or broker asks to be named as an "additional insured" on your policy, they're asking for coverage under your policy for claims arising from your operations on their behalf. This is common and usually reasonable. But understand what you're granting: - They can file claims directly against your policy - They receive defense coverage under your policy - Your policy limits are shared between you and all additional insureds Most auto liability policies allow additional insureds by endorsement. Cargo policies typically don't. If a broker asks to be additional insured on your cargo policy, that's unusual and worth discussing with your agent. Certificate Management For fleets with multiple customers, certificate management becomes a significant administrative task. Tips: - Keep a master list of all certificate holders and their requirements - Set calendar reminders 30 days before expiration to issue renewals - Use your agent's certificate system (we issue certificates same-day at Trux) - Review each request against your actual coverage before issuing The Trux Approach We issue certificates for our clients within hours of request — often within minutes for standard requests. We also review incoming certificate requests to ensure they match your actual coverage and flag any that would require policy changes. If a shipper is asking for something your policy doesn't provide, we'll tell you before you sign the contract — not after a claim is denied.
