Bobtail Insurance: Liability Coverage When You’re Running Without a Trailer.

Most owner operators assume they’re covered the moment they drop a trailer. They aren’t. Your primary liability coverage from a motor carrier typically applies while you’re under dispatch and hauling a load.

What Is Bobtail Insurance?

Bobtail insurance is liability-only coverage for your truck when it’s being driven without a trailer attached. “Bobtailing” simply means running the tractor on its own, no cargo, no trailer.

It applies in situations like:

  • Driving away after dropping off a load at the destination
  • Heading to pick up your next assigned load with no trailer attached
  • Deadheading between jobs under your carrier’s dispatch

Bobtail insurance covers third-party bodily injury and property damage if you cause an accident while running bobtail. It does not cover damage to your own truck. It does not cover cargo, because there isn’t any cargo to cover when you’re bobtailing.

Scope of coverage

What Bobtail Insurance Does and Doesn’t Cover

Bobtail insurance is a narrow, liability-only product. Here is what sits inside the policy and what falls outside it.

01

Bodily injury to a third party you cause while bobtailing

Not covered

Damage to your own tractor (requires physical damage coverage)

02

Property damage to another vehicle or property

Not covered

Cargo or freight (not applicable while bobtailing)

03

Legal defense costs if you’re sued following an at-fault accident

Not covered

Personal use of the truck unrelated to dispatch (requires non-trucking liability)

04

Settlement costs within your policy limits

Not covered

Mechanical breakdown or wear and tear

Bobtail insurance is liability-only by design. If you want your own truck protected during a bobtail run, you need physical damage coverage layered on top.

Bobtail Insurance vs. Non-Trucking Liability: They Are Not the Same

This is the single most common point of confusion in the owner operator insurance world, and getting it wrong leads to denied claims.

The distinction comes down to one question: are you under dispatch or not?

Bobtail insurance is typically written to apply when you’re driving the tractor without a trailer while still operating under your carrier’s authority and dispatch. You finished a delivery, dropped the trailer, and you’re driving to your next pickup. You’re still working. There’s just no trailer attached.

Non-trucking liability (NTL) is typically written to apply when you’re using the truck for personal reasons, completely off dispatch. A grocery run, a trip home, anything unrelated to the carrier’s business. Whether a trailer is attached or not is irrelevant to NTL. What matters is that you’re off the clock.

Those are the common setups, not universal rules. The trigger that decides a claim is the wording in your own policy and lease, and some carriers and endorsements draw the line differently, so confirm yours rather than relying on the general shape.

Side by side

Bobtail vs. Non-Trucking Liability at a Glance

Same truck, two different operating states. The trigger is dispatch status, not whether a trailer happens to be attached.

Bobtail Insurance

No trailer, under dispatch

What it pays for

Third-party bodily injury and property damage while you drive the tractor with no trailer attached and you are still operating under your carrier’s authority and dispatch. Trailer status is always no trailer. Working status is on the job, between loads.

Common example

Driving to pick up the next load.

Non-Trucking Liability

Personal use, off dispatch

What it pays for

Third-party liability while you use the truck for personal reasons, completely off dispatch. Trailer status is irrelevant. Working status is not working.

Common example

Driving to the grocery store on a day off.

Some lease agreements require both. Read your lease carefully. Assuming one covers a situation that actually falls under the other is one of the most common reasons trucking liability claims get denied.

Bobtail Liability Limits: What Owner Operators Typically Carry

Most bobtail policies are written with the same liability limit as your primary auto coverage, commonly $1,000,000. Some motor carriers specify a minimum bobtail limit in the lease agreement, so check your contract before assuming a lower limit is acceptable.

Carrying a limit below what your lease requires can put you in breach of contract, even if the coverage itself is otherwise valid.

What Bobtail Insurance Costs in 2026

Bobtail insurance is one of the more affordable coverages in the owner operator stack, because it’s liability-only and the exposure window is relatively narrow. Typical 2026 market range: $20 to $60 per month for standalone bobtail/NTL liability coverage at the $1,000,000 limit.

01

Clean MVR, established authority

Estimated monthly cost

$20 to $35

02

Average driving record

Estimated monthly cost

$35 to $50

03

Recent violations or new authority

Estimated monthly cost

$50 to $80+

These are indicative 2026 market ranges, not quotes. Your actual premium depends on the rate drivers below.

Rate drivers

What Affects Your Bobtail Rate

Five inputs move the number more than anything else on a standalone bobtail submission.

Driving record

Your MVR and any prior at-fault accidents. This is the single largest swing factor between the low and high end of the market range.

Liability limit selected

Most policies mirror the primary auto limit at $1,000,000. A higher limit raises the premium; a lower one may breach your lease.

How often you run bobtail

Underwriters look at bobtail miles relative to loaded miles. The more of your week is spent without a trailer, the wider the exposure window.

Garaging location and operating state

Where the tractor sits overnight and which states you run through both feed the rate. Urban garaging and litigation-heavy states cost more.

Bundled or standalone

Whether bobtail is purchased on its own or written alongside physical damage and non-trucking liability. Bundling usually lowers the combined premium.

Bundling bobtail with physical damage and other coverages often reduces the combined premium compared to purchasing each separately.

Do You Actually Need Bobtail Insurance?

If you’re leased to a motor carrier and regularly drive without a trailer between loads, the answer is almost always yes. Most carriers require it as a condition of the lease.

If you operate under your own authority, your primary liability policy may already extend to bobtail situations, depending on how the policy is written. Confirm this directly with your broker rather than assuming it’s included.

According to the Insurance Information Institute, liability coverage exists specifically to protect a business from financial loss when it’s responsible for property damage or bodily injury to a third party. A bobtail accident is exactly that kind of exposure, even without a load attached.

How Bobtail Fits Into Your Full Coverage Stack

Bobtail insurance is one layer of a larger stack most owner operators need. On its own, it covers a narrow but real gap. It does not replace primary liability, cargo coverage, or physical damage.

The FMCSA requires minimum liability filings for for-hire carriers operating under their own authority, separate from any bobtail or NTL coverage you carry. If you’re building your full coverage picture, our guide to owner operator insurance breaks down how all the pieces fit together.
