If you lease your truck to a motor carrier, there is a coverage gap most owner-operators do not see until a claim falls into it. Here is how it works and how to close it.
The dispatch line
When you lease on to a carrier, that carrier’s primary liability policy generally covers you only while you are under dispatch, hauling their load. The moment you are doing something else, deadheading for personal reasons, driving home, running an errand, that coverage generally does not apply. The carrier’s policy is built to cover their business, not your personal use of the truck.
Bobtail vs non-trucking liability
The two terms overlap but differ. Bobtail liability traditionally refers to operating the tractor without a trailer attached. Non-trucking liability is broader: it covers use of the truck that is not in the business of the carrier you lease to. In practice, non-trucking liability is the coverage most leased owner-operators actually need, and bobtail is sometimes used loosely to mean the same thing.
Your lease defines the line
The lease between you and the motor carrier defines when their coverage applies and when it stops, which is exactly the line your bobtail or non-trucking liability has to pick up. Reading the lease against the coverage is how you confirm there is no gap between dispatch and personal use.
What it does not do
Non-trucking liability covers your liability off dispatch; it does not cover the freight, the trailer, or your truck’s physical damage, those are separate coverages. And it is not the same as having your own authority and full primary liability, which is a different setup entirely.
The gap where these claims actually happen
The reason non-trucking liability and bobtail coverage exist is a specific gap, and the classic claim lands right in it. Picture a leased owner-operator who drops a load, unhooks the trailer, and drives the tractor home for the weekend. They are not under dispatch, so the motor carrier’s primary liability policy, which covers them while working for the carrier, may not respond. But they are still driving a commercial tractor, which their personal auto policy will not touch. That is the seam: off dispatch, off the carrier’s policy, and outside personal auto. Non-trucking liability covers use of the truck when it is not being used in the business, and bobtail specifically addresses driving the tractor without a trailer. Which one you need, and how it lines up with your lease and the carrier’s policy, is exactly the detail that gets missed until a weekend drive home becomes an uninsured claim.
Questions to ask your advisor
- Does the carrier’s policy cover me only under dispatch, and where does it stop?
- Do I carry bobtail or non-trucking liability for off-dispatch use?
- Does my coverage line up with what my lease actually says?
- What is left uncovered, the truck, the trailer, the freight, when I am off dispatch?
- Would my situation be better served by non-trucking liability, bobtail, or my own authority?
If you are leased on, confirm you carry bobtail or non-trucking liability and that it matches your lease. A quick review closes a gap that can be very expensive.
