Named Insured vs Additional Insured in Trucking (2026)
Sooner or later every owner-operator gets the same broker email: "Send a COI listing us as certificate holder and additional insured, primary and noncontributory." That one sentence hides three different legal statuses — and mixing them up is expensive. Here is how they work in 2026.
Named insured vs additional insured vs certificate holder — who gets what?
The named insured is the business listed in the policy declarations — normally the motor carrier whose USDOT/MC number the trucks run under. It has full rights: pays the premium, can amend or cancel coverage, and is covered for its own negligence. An additional insured is an outside party — broker, shipper, warehouse owner — granted coverage by endorsement, generally only for liability arising out of the named insured's operations. A certificate holder merely receives an ACORD 25 certificate — the form itself says it "confers no rights upon the certificate holder."
| Status | Coverage for own liability | Premium duty | Can change policy | Cost to add |
|---|---|---|---|---|
| Named insured | Full, including own negligence | Pays 100% | Yes | — |
| Additional insured | Only liability from named insured's operations | $0 | No | $0 to a modest fee |
| Certificate holder | None — information only | $0 | No | Usually free |
Which endorsements do brokers and shippers actually demand?
On general liability the standard ISO forms are CG 20 10 (scheduled, ongoing operations), CG 20 26 (Designated Person or Organization — scheduled, works even without a contract requirement), CG 20 33 (blanket status for any party a written contract requires, ongoing operations only) and CG 20 38 (blanket, extends to upstream parties of a written construction agreement). On commercial auto the key tool is CA 20 48, Designated Insured: it covers the designated party's vicarious liability from use of your covered autos — not the broker's own trucks or its own negligence.
For scale: FMCSA liability minimums under 49 CFR 387.9 are $750,000 for general freight, $1,000,000 for oil and $5,000,000 for certain hazmat. Broker-carrier agreements typically demand $1,000,000 auto liability and $100,000 cargo on top — plus additional-insured wording.
| Form | Line | Blanket or scheduled | Written contract required? |
|---|---|---|---|
| CG 20 10 | GL | Scheduled | No |
| CG 20 26 | GL | Scheduled | No |
| CG 20 33 | GL | Blanket | Yes, before the loss |
| CG 20 38 | GL | Blanket, upstream parties | Yes |
| CA 20 48 (10 13) | Auto | Scheduled | No — vicarious liability only |
Blanket or scheduled additional insured — what should you buy?
- Blanket (CG 20 33 / CG 20 38): automatically covers whoever your written contracts require — no waiting for each new endorsement. It responds only if a signed contract existed before the loss.
- Scheduled (CG 20 10 / CG 20 26 / CA 20 48): each party is typed onto the form. Slower, but you always know who sits on your policy.
What does "primary and noncontributory" mean — and what are the hidden risks?
Primary-and-noncontributory wording (on GL, ISO endorsement CG 20 01, edition 04/13) means your policy pays first and your insurer will not seek contribution from the additional insured's own insurance when a written contract requires it. Adding parties is cheap — certificates are usually free, blanket forms are priced into premium — but the real bill arrives at claim time:
- Limit dilution: the broker's defense and indemnity draw from the same $1,000,000 limit that protects you.
- Defense obligations: depending on the form, your insurer may owe the additional insured a defense even when its own conduct contributed to the loss.
- Loss runs: payments made for additional insureds land on your loss history and raise renewal premium.
- Waiver of subrogation demands strip your insurer's right to recover from an at-fault party.
Rule: grant the status only under a signed written contract, and keep every contract on file.
Owner-operator leased to a carrier: who is named on whose policy?
Under federal leasing rules the logic flips. 49 CFR 376.12(c)(1) requires the lease to give the authorized carrier "exclusive possession, control, and use" of the equipment. Section 376.12(j) makes the lease state that the carrier maintains public liability insurance under 49 U.S.C. 13906, say who buys everything else (such as bobtail), disclose the exact insurance chargeback deducted from settlements, and provide a certificate and policy copies on request. The carrier's policy names the carrier; the owner-operator personally buys non-trucking/bobtail liability, physical damage and occupational accident coverage.
Illustrative case (composite). Arseniy, an owner-operator from Sacramento leased to a regional carrier, assumed "the company insurance covers everything." A deer strike on a weekend deadhead run proved otherwise: the carrier's liability policy owed third parties, not his tractor, and he had never bought physical damage — a $38,000 repair out of pocket. His lease listed a monthly insurance chargeback, yet he never used his 376.12(j) right to demand copies of the actual policies.
Why this hits Russian-speaking owner-operators especially hard
In Russian-speaking trucking hubs — Sacramento, Brooklyn, Edison NJ, Cleveland, Miami — leases and broker packets circulate in English while the deal is discussed in Russian, and "named insured," "additional insured" and "certificate holder" all collapse into one phrase: "strakhovka est." Before signing, demand three things: the endorsement itself, not just the COI; the lease insurance clause with chargeback amounts per 376.12(j); and written confirmation whether your wording is blanket or scheduled.

FAQ
Who is the named insured on a trucking policy?+
The business in the policy declarations — usually the motor carrier holding the USDOT/MC number. It pays the premium, controls the policy, and is covered for its own negligence.
What does additional insured status give a broker or shipper?+
Coverage under your policy for liability arising from your operations, via endorsements like CG 20 33 (GL) or CA 20 48 (auto). No premium duty and no right to change your policy.
Is a certificate holder covered by the policy?+
No. The ACORD 25 form states it is issued for information only and confers no rights on the holder. Coverage is created only by an endorsement to the policy itself.
Blanket vs scheduled additional insured — which is better?+
Blanket (CG 20 33/CG 20 38) auto-covers parties your written contracts require; scheduled (CG 20 10/CG 20 26) names each one. Blanket suits carriers juggling many brokers.
How much does it cost to add an additional insured?+
Direct cost is small — often free or a modest per-endorsement fee, with blanket forms priced into premium. The hidden cost: shared limits, extra defense duties, worse loss runs.
What does primary and noncontributory mean?+
Your policy pays first and your insurer won't seek contribution from the additional insured's own coverage. On GL, ISO endorsement CG 20 01 (04/13) adds it when a contract requires.
Who insures a leased owner-operator under 49 CFR 376?+
The carrier must hold public liability coverage (49 CFR 376.12(j)) and takes exclusive possession under 376.12(c)(1). The O/O buys bobtail, physical damage, occupational accident.
What are the FMCSA minimum liability limits in 2026?+
Under 49 CFR 387.9: $750,000 for general freight, $1,000,000 for oil, $5,000,000 for certain hazmat. Broker contracts usually demand $1,000,000 auto liability anyway.
