What is Bobtail Insurance? A Trucking Insurance Guide

Bobtail insurance is a commercial trucking liability policy that covers an owner-operator when they are driving their semi-truck without a trailer and are not under dispatch. It protects against liability claims that occur during those “between loads” miles — trips to the fuel station, the truck stop, or home — when the motor carrier’s primary liability policy does not apply.

What Is Bobtail Insurance?

When an owner-operator leases their truck to a motor carrier, the carrier’s primary liability policy covers them while hauling under dispatch. But the moment they drop the trailer and drive their tractor solo — or go home for the weekend — the carrier’s coverage typically stops applying. Bobtail insurance steps in to cover liability during those off-dispatch miles.

The name comes from the visual: a semi-truck driving without a trailer looks like a bobcat with a short, stubbed tail. The tractor alone is the “bobtail.”

According to Nazar Mamaev, trucking insurance specialist at Full Coverage LLC, “Bobtail coverage is required by virtually every carrier that leases owner-operators. Without it, you have a window of exposure every time you drop a trailer. It’s one of the cheapest coverages in trucking and one of the most essential.”

When Does Bobtail Insurance Apply?

Bobtail insurance triggers when ALL of the following are true:

• You are driving your tractor without a trailer attached
• You are NOT currently under dispatch (not on an active load or assignment)
• You are operating the truck for personal or transitional use (going home, to a fuel stop, to a service center)

If you are driving bobtail (no trailer) but ARE under dispatch — for example, driving to a shipper to pick up a trailer — the carrier’s primary liability usually covers you. Check your lease agreement to confirm.

Who Needs Bobtail Insurance?

Bobtail insurance is typically required for:

• Owner-operators leased to a carrier – Almost all carrier lease agreements require bobtail or non-trucking liability as a condition of the lease
• Lease-purchase drivers – Drivers in lease-to-own programs who drive the truck to and from home
• Dedicated contract drivers – Drivers who regularly drive bobtail between assignments

Owner-operators running under their own authority (independent MC number) typically carry primary liability that covers them at all times, so separate bobtail coverage is less critical — though some still carry it for the gap between policy periods.

Bobtail Insurance Cost and Coverage Details

Bobtail insurance is one of the most affordable trucking coverages available. Typical costs:

• Monthly premium: $35–$60/month for most owner-operators
• Annual premium: $400–$720/year
• Liability limits: Typically $1,000,000 combined single limit (CSL)
• Deductible: Usually $0–$1,000

Factors affecting bobtail premium include your driving record (MVR), years of CDL experience, garaging state, and whether you’ve had prior bobtail claims. Drivers with 3+ years clean record pay toward the lower end of the range.

Bobtail insurance typically covers bodily injury and property damage liability only. It does NOT cover physical damage to your own truck — you’d need a separate physical damage policy for that.

Bobtail vs. Non-Trucking Liability: Key Differences

These two coverages are often sold together or used interchangeably by some carriers, but there is a technical distinction:

• Bobtail insurance – Covers driving a tractor without a trailer, not under dispatch
• Non-trucking liability (NTL) – Covers personal use driving (with OR without a trailer), not under dispatch

If you tow a personal trailer or use your truck for personal errands, NTL is the more complete coverage. Most carriers that require “bobtail” actually want NTL and use the terms interchangeably. Confirm with your agent which specific trigger applies under the policy you’re being offered.
