Non-Trucking Liability and Bobtail Insurance: When You Need Them
Title tag: Bobtail Insurance vs. Non-Trucking Liability | Kaufman Insurance Group
Meta description: Learn when leased-on owner-operators need bobtail insurance or non-trucking liability, what carrier policies may cover, and how to review the gaps.
By Kaufman Insurance Group
If you’re leased onto a motor carrier, don’t assume their commercial auto policy follows you everywhere you go. A lot of owner-operators think it covers every mile, and that’s where the confusion starts.
In plain terms, the carrier’s primary liability generally applies when you’re under dispatch or doing something for that carrier’s business. Your own coverage may apply when you’re off dispatch, using the truck for personal reasons, or running the tractor without a trailer attached.
That’s where bobtail insurance and non-trucking liability come in. People mix those terms together all the time. Sometimes the policy setup does overlap. Sometimes it doesn’t, and the policy definitions and exclusions decide which coverage applies.
Start with the difference between bobtail and non-trucking liability
The easiest way to sort this out is to look at what actually triggers the coverage.
Bobtail insurance usually means liability coverage for a tractor when there’s no trailer attached. You might be going to the yard, heading to a shop, stopping for fuel, or driving home. Whether the policy applies can still depend on dispatch status and the way that policy defines bobtail use.
Non-trucking liability insurance, usually called NTL, is more about why you’re driving than whether a trailer is hooked up. It’s generally meant for personal, off-dispatch use while you’re leased to a motor carrier.
NTL may apply when you use the truck to:
- Drive home after a dispatch is done.
- Grab food or handle a personal errand.
- Go to a doctor or another personal appointment.
- Take the tractor to a mechanic for a repair that the carrier didn’t send you for.
You can be bobtailing on one of those trips, but that doesn’t mean the coverages are the same thing. Some policies package the protection together. Others split it up and define bobtail use one way and non-trucking use another way.
Before you rely on either term, review the policy wording to see how the coverage is defined and what exclusions apply.
When the carrier’s policy usually applies
If you’re leased on, the motor carrier’s primary liability policy is generally the one you look to when you’re operating in that carrier’s business.
Common examples are:
- Hauling a loaded trailer on a dispatched load.
- Deadheading to pick up a load because the carrier sent you there.
- Moving between the shipper, receiver, terminal, or yard under instructions.
- Taking the tractor and trailer in for a required inspection or a repair the carrier directed.
- Going to fuel when that stop is part of an active dispatch.
In those situations, you’re usually operating under the carrier’s authority and for the carrier’s business purpose. That policy is typically meant to respond to third-party bodily injury or property damage claims.
Your lease, your dispatch status, and the policy definitions all affect the outcome. A driver may think coverage still applies because he dropped a load not long ago, but the claim can still turn on whether he was under dispatch or doing something on his own at that point.
Ask the carrier where their liability starts and where they say it ends. Then line that up with the lease and with your own policy wording.
Federal leasing rules also require the lease to spell out the carrier’s insurance responsibility and who provides other coverage, including bobtail insurance. You can review the insurance provision in 49 CFR § 376.12.
When you may need NTL coverage
NTL is commonly required when an owner-operator is permanently leased to a motor carrier. The carrier may provide the primary liability while you’re dispatched, but personal use of the truck can be outside that setup.
Here’s the kind of example that comes up all the time. You deliver a load, nobody gives you another dispatch, and you head home in the tractor with no trailer attached. The trip is over and you’re on your own time, so that trip may not fall under the carrier’s policy. Your NTL or bobtail coverage may be the one expected to respond.
Other examples can include:
- Driving to get food while you’re off duty.
- Taking the truck to a personal appointment.
- Using the tractor during home time.
- Driving to a repair shop for a repair you decided to handle yourself.
- Moving the tractor to storage when the carrier didn’t send you there.
NTL usually covers third-party liability. In other words, it may help with injury or property damage claims from someone else after a covered accident.
It usually doesn’t cover damage to your own truck. For that, you may need physical damage coverage for collision, theft, fire, and other covered causes of loss. It also doesn’t replace motor truck cargo coverage, because cargo coverage deals with the freight, not the liability claim from the other side.
What bobtail insurance does and does not mean
Bobtailing describes the equipment. It means a tractor is operating without a trailer, and that alone does not answer the coverage question.
A tractor can be bobtailing:
- After a delivery while you’re going home.
- On the way to pick up a trailer.
- Between carrier locations.
- On a trip to get fuel or handle a repair.
- During personal home time.
Some bobtail policies apply when you’re operating without a trailer, whether you’re under dispatch or not. Other policies only apply to non-dispatched bobtail use. And sometimes the carrier’s own primary liability may still apply to a tractor-only movement if that trip is part of the carrier’s business.
I’ve seen NTL claims denied because the driver was on the way to pick up another load, even though the trailer wasn’t attached yet. From the driver’s point of view, he was just in the tractor. From the policy’s point of view, he was already back in the business of trucking.
Check whether the policy uses terms like:
- “Under dispatch”
- “In the business of trucking”
- “In furtherance of the motor carrier’s business”
- “Non-trucking use”
- “Personal use”
- “Bobtailing”
The definitions and exclusions are what decide which policy is supposed to respond.
A practical coverage guide for common trips
Use this table as a starting point. Then compare it to your lease and the actual policy wording.
| Driving situation | Coverage that may typically apply |
|---|---|
| Hauling a loaded trailer on an assigned load | Carrier’s primary liability |
| Deadheading to a pickup at the carrier’s direction | Carrier’s primary liability |
| Moving between terminals under carrier instructions | Carrier’s primary liability |
| Driving home after dispatch ends | NTL or bobtail, depending on policy wording |
| Driving to get a personal meal during home time | NTL |
| Taking the tractor to a personal appointment | NTL |
| Driving to a carrier-required repair facility | Carrier’s policy may apply |
| Driving to a personal mechanic with no carrier direction | NTL or bobtail, depending on policy |
| Tractor-only travel during an active dispatch | Carrier’s policy may apply |
Look at the whole trip. Ask who sent you, whether you were under dispatch, whether the trip was helping the carrier’s business, and whether the policy excludes that kind of use.
Review your lease before choosing coverage
Your lease should say who provides primary liability and who is responsible for the other insurance around it. Federal rules require that insurance responsibility to be addressed, including coverage such as bobtail insurance.
Before you buy or renew coverage, review:
- The carrier’s insurance obligation. Pin down when the carrier’s primary liability applies.
- Your insurance responsibility. Look for NTL, bobtail, physical damage, cargo, and any other required coverage.
- Charge-backs. Check whether the carrier is charging you for insurance and what that actually includes.
- Dispatch language. Find the definition of “under dispatch” or similar wording.
- Policy exclusions. Look for exclusions tied to personal use, off-dispatch driving, or another trucking operation.
Keep copies of the lease, certificates, policy documents, and any written instructions from the carrier. When a claim happens, people start reconstructing the trip after the fact, and those documents help show what you were doing and who you were doing it for.
What affects bobtail insurance cost?
There isn’t one bobtail insurance cost for every owner-operator. Pricing depends on the coverage being offered and details like:
- Your driving history and claims record.
- The truck type, age, and value.
- Where the truck is garaged and operated.
- Your experience and how long you’ve been with the carrier.
- The liability limit required.
- Whether the policy includes broader non-trucking use.
- Your deductible and payment plan.
- The carrier and the state where coverage is available.
The cheapest premium on the page may leave out wording your lease expects you to carry, so compare the limits, exclusions, and the kinds of trips that are actually covered, not just the price.

Do I need bobtail insurance?
You may need bobtail insurance, NTL, or both. That depends on your lease and on how the policy defines the covered use.
Start with these questions:
- Do you operate a tractor without a trailer?
- Do you drive while you’re off dispatch?
- Does the carrier’s primary liability exclude personal or non-trucking use?
If the answer to any of those is yes, review the policy before you assume you’re covered. An agent can compare the lease requirements with the available policy language and tell you where the gap may be.

Frequently asked questions
Do I need bobtail insurance if my carrier provides primary liability?
Maybe. The carrier’s primary liability generally applies while you’re under dispatch or working in the carrier’s business. Personal, off-dispatch driving may fall outside that. Review the lease and the carrier’s requirements before you decide.
Is bobtail insurance the same as non-trucking liability?
No, not always. Bobtail describes a tractor without a trailer. NTL refers to off-dispatch, non-business use. One policy may address both situations, or it may not. The definitions and exclusions control that answer.
Does NTL cover driving to get fuel?
It depends on why you’re going for fuel and what the policy says. If you’re fueling during an active dispatch, that may be treated as part of the carrier’s operation. If you’re on personal home time, it may be treated differently. Ask about that specific scenario before there’s a claim.
Does NTL cover damage to my truck?
Usually no. NTL is generally third-party liability coverage. Physical damage coverage is what usually addresses damage to your own tractor.
Can NTL cover me with a trailer attached?
Sometimes, depending on the policy and the reason for the trip. Some policies may allow coverage if the use is personal and off dispatch. Others restrict coverage based on the trailer, the load status, or the purpose of the trip. Get that clarified in writing.
Review the gap before you drive
The right coverage depends on your lease, dispatch status, equipment, and the policy wording. Coverage names by themselves do not show when a policy applies.
