Liability coverage for an owner-operator’s truck while it’s leased to a motor carrier but not working for it: personal trips, days off and the time the truck is yours again.

The carrier insures its time. This insures yours.
Federal leasing rules set what a lease between an owner-operator and an authorized carrier must say. The carrier gets exclusive possession, control and use of the truck for the length of the lease and takes complete responsibility for operating it, and the lease has to state the carrier’s legal obligation to keep public liability insurance. FMCSA guidance adds that a truck deadheading or bobtailing while in the service of a motor carrier is subject to the federal financial responsibility rules, so that time falls on the carrier to insure.
What’s left is the time the truck isn’t in the carrier’s service, and that’s what non-trucking liability is for. Bobtailing just means driving a tractor without a trailer, but the federal leasing rule uses “bobtail insurance” as its example of the other insurance a lease must assign, and the two names are often used for the same coverage. The real differences sit in the exclusions, so I read the wording, not the label. My comparison page on non-trucking liability vs. bobtail goes further into the gray areas.
- In the carrier’s serviceThe carrier’s liability, loaded or empty, under the federal rules.
- Your own useNon-trucking or bobtail coverage, if you carry it.
- Federal minimum$750,000 for for-hire general freight in trucks rated 10,001 pounds or more.
- Your leaseMust say who provides other insurance, such as bobtail, and any amount charged back.
What underwriters will ask
Having these ready means I can go to market on the first call. The quote form asks for the same things, and anything you don’t know yet can wait.
- Lease: a copy of your lease, especially the insurance and charge-back sections.
- Carrier: who you’re leased to and its USDOT number.
- Truck: year, make, VIN and where it’s parked at night.
- Driver: CDL, years of experience and motor vehicle record.
- Current coverage: any certificate or settlement statement showing what the carrier provides.
- Use: how often and how far the truck moves off dispatch.
The lease clauses that decide your insurance
Before I shop non-trucking liability, I read your lease against 49 CFR 376.12. It lists what the lease must say, so raise a missing clause with the carrier before you sign.
- Insurance, 376.12(j)(1). The lease must describe the carrier's legal duty to keep the insurance 49 U.S.C. 13906 requires to protect the public, name who provides any other insurance for operating the truck, "such as bobtail insurance," and state the amount charged back to you if the carrier passes that cost on.
- Coverage bought through the carrier, 376.12(j)(2). If you buy insurance through the carrier, it must give you a copy of each policy on request and a certificate showing the insurer, policy number, dates, types and amounts of coverage, cost, and deductibles.
- Damage deductions, 376.12(j)(3). The lease must say when cargo or property damage deductions can be taken, and the carrier owes you a written, itemized explanation before deducting.
- Charge-backs, 376.12(h). Every item the carrier may pay first and deduct from your settlement must be listed with how the amount is computed, and you get copies of the documents needed to check that each charge is valid.
- No forced purchases, 376.12(i). The lease must say you are not required to buy or rent products, equipment or services from the carrier as a condition of signing it.
- Pay terms, 376.12(d) and (g). Compensation must be on the face of the lease or in an attached addendum delivered before any trip. On percentage pay, you are entitled to the rated freight bill at or before settlement.
The (j)(2) certificate shows exactly what the carrier's charge-back buys, so I can line it up against a policy in your own name. Send it with the lease. If you are weighing your own authority instead, see leased versus own authority.
Bobtail, deadhead, unladen: the words underwriters use
IRMI's insurance glossary separates terms that drivers often run together:
- Bobtailing means driving with no trailer attached; deadheading means pulling an empty trailer with no cargo.
- Bobtail liability is IRMI's name for auto liability for an owner-operator after a load is delivered, when the truck is not being used in trucking, such as driving home. IRMI lists nontrucking liability as a synonym and says it is written as a business auto policy with the Truckers Insurance for Non-Trucking Use endorsement, form CA 23 09.
- Unladen liability applies when a truck runs with an empty trailer or no trailer, whether or not it is dispatched. IRMI notes the terms are often used interchangeably but calls unladen liability broader in scope.
That dispatch line is the one I check. Under IRMI's definitions, a missing or empty trailer does not settle the question by itself: bobtail and non-trucking coverage is described by whether the truck is being used in trucking, while unladen coverage is described by the empty run, dispatched or not. The policy's own wording controls. When you tell me how you drive off duty, describe where you're going and whether you're under a load assignment, not just whether a trailer is hooked up. The side-by-side is on non-trucking liability vs. bobtail.
Non-trucking liability, answered
What’s the difference between non-trucking liability and bobtail insurance?
Bobtailing means driving a tractor without a trailer, but in insurance the two names are often used for the same coverage: liability for the truck when it isn’t working for the carrier it’s leased to. Two policies sold under either name can be worded differently, so I compare the exclusions rather than the label.
Does non-trucking liability cover me when I’m deadheading for my carrier?
Generally not. FMCSA guidance says a truck deadheading or bobtailing while in the service of a motor carrier is subject to the federal financial responsibility rules, so that time is the carrier’s to insure. Non-trucking coverage is written for use outside the carrier’s business.
Do I need it if I have my own authority?
No. A carrier running under its own authority needs primary auto liability that covers trucking use, at least $750,000 for for-hire general freight in trucks rated 10,001 pounds or more. Non-trucking coverage can’t stand in for it.
Does non-trucking liability cover damage to my truck?
No. It covers injury or damage you cause to other people. Damage to your own tractor needs physical damage coverage.
My carrier deducts insurance from my settlements. Is that allowed?
The lease must say who provides insurance beyond the carrier’s public liability coverage, and if the carrier charges it back to you, the lease must state the amount. If you buy coverage from or through the carrier, the lease must require the carrier to give you a copy of the policy on request and a certificate showing the insurer, policy number, dates, coverage, your cost and the deductibles you could owe.
Do you offer non-trucking liability insurance outside California?
Yes. Clients across the country send the same quote form. Sam Alishahi is licensed in all 50 states and Washington, DC and places policies there directly. The shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
