Is bobtail insurance the same as non-trucking liability?

Not exactly, although the terms are often used interchangeably. Bobtail refers to driving the tractor without a trailer; non-trucking liability refers to personal, non-business use off dispatch. Some policies cover both situations and others do not, so the policy wording decides.

Do I need bobtail or non-trucking liability if I have my own authority?

Generally no. Carriers running under their own authority carry primary commercial trucking liability, which covers the truck whether it is under load or not. NTL and bobtail coverage are designed for owner-operators leased onto another motor carrier.

Does non-trucking liability cover me while I drive to pick up a load?

Usually not. If you are under dispatch, the motor carrier's primary liability generally responds. If you are driving for a business purpose but not under dispatch, a pure non-trucking policy typically excludes it, which is the gap some bobtail forms are written to fill.

Does bobtail or non-trucking liability cover damage to my own truck?

No. Both are liability coverages that pay for injury and damage you cause to others. Damage to your own tractor is covered by physical damage insurance.

Who requires non-trucking liability insurance?

Many motor carriers require their leased owner-operators to carry non-trucking liability as a condition of the lease, because the carrier's own policy may not respond when the truck is used for personal purposes. Check your lease agreement for the exact requirement and limit.

Bobtail vs. Non-Trucking Liability Insurance: What's the Difference?

Bobtail insurance and non-trucking liability (NTL) both protect leased owner-operators when the motor carrier's liability policy is not responding, but they are triggered by different things. Bobtail is about driving the tractor without a trailer; non-trucking liability is about using the truck for personal, non-business purposes. Your lease agreement and the policy wording decide which one you need.

Why the two get confused

Drivers, carriers, and even insurers use "bobtail" and "non-trucking liability" interchangeably, and policies are not all written the same way. That is why two owner-operators can both say they "have bobtail" and be covered for very different situations. The safest way to think about it is by the trigger: what you are doing with the truck at the moment of the accident.

What is non-trucking liability insurance?

Non-trucking liability covers bodily injury and property damage you cause to other people while you are using your truck for personal, non-business purposes, off dispatch. Think driving home after you have been released from a load, or running a personal errand in the tractor.

It exists because the motor carrier's primary liability policy is built to cover the truck while it is working for the carrier. Once you are off dispatch and using the truck for yourself, that policy may not respond, and NTL fills the window.

What is bobtail insurance?

"Bobtailing" means driving a tractor without a trailer attached. Bobtail coverage is liability coverage written around that situation. Depending on the policy form, it may also respond when you are driving without a trailer for a business purpose while not under dispatch, which a pure non-trucking policy usually excludes.

Bobtail coverage typically does not respond while you are pulling a trailer, loaded or empty. Read the exact wording, because this is where policies differ most.

Bobtail vs. non-trucking liability at a glance

General comparison. Exact coverage depends on the policy form and your lease agreement.
	Non-trucking liability (NTL)	Bobtail
What triggers it	Personal, non-business use while off dispatch	Driving the tractor without a trailer
Typical buyer	Owner-operators leased onto a motor carrier	Owner-operators leased onto a motor carrier
Business use not under dispatch	Usually excluded	Depends on the policy wording
While hauling for the motor carrier	No, the carrier's primary liability applies	No, the carrier's primary liability applies
Pulling a trailer, loaded or empty	Only if the use is personal and off dispatch	Usually not covered
Damage to your own truck	No, that is physical damage coverage	No, that is physical damage coverage

Which one do you need?

Leased onto a motor carrier: start with your lease agreement. It usually spells out which coverage the carrier requires, and many carriers specify non-trucking liability.
Running under your own authority: you generally need neither. Your primary commercial trucking liability should cover the truck whether you are under load or not.
Not sure where the carrier's coverage stops: ask the carrier, in writing, exactly when its policy responds and when it does not. Your coverage should start where theirs ends.

Common mistakes we see

Assuming NTL covers you while you are dispatched and running empty to a pickup. Under dispatch, the motor carrier's primary liability is generally the policy that responds.
Keeping an NTL policy after getting your own authority, which leaves the truck without the primary liability the FMCSA requires.
Forgetting that neither coverage pays to repair your own tractor. That takes physical damage coverage.
