When the Trailer's Gone and You're No Longer Under Dispatch.
Liability protection for the tractor running without a load
Bobtail insurance is liability coverage that responds when a tractor is operated without a trailer attached — or with an empty one — while the driver is not under dispatch and not hauling freight for the motor carrier. "Bobtailing" describes that configuration: a tractor running with no trailer, the way a bobtailed animal has a short tail.
The classic scenario is an owner-operator who drops a loaded trailer at the receiver, unhooks, and drives the naked tractor back to the yard or home. During that stretch the truck is not actively hauling, so the motor carrier's primary liability — which covers the truck while under dispatch with a load — may not respond. Bobtail fills that gap for third-party injury and property damage the driver causes to others.
What Bobtail Insurance Covers
Bobtail is defined by the vehicle's state — no trailer, off-load — rather than by whether the trip is personal:
Third-Party Bodily Injury — Covers injuries the driver causes to others while operating the tractor without a trailer and off dispatch.
Third-Party Property Damage — Covers damage the driver causes to others' vehicles or property while bobtailing.
Legal Defense Costs — Pays the cost of defending covered liability claims, subject to policy terms.
What It Does Not Cover
Bobtail is narrow, liability-only coverage, so it excludes:
Any period the truck is under dispatch and hauling a loaded trailer (the motor carrier's primary liability)
Cargo and freight (covered by motor truck cargo)
Physical damage to the insured's own tractor (covered by physical damage)
The driver's own injuries (covered by workers' compensation or occupational accident)
Revenue-generating business use, depending on the specific policy wording
Who Needs Bobtail Insurance
Bobtail coverage fits owner-operators whose tractor is insured by the carrier only while working, including:
Owner-operators leased to a motor carrier under the carrier's primary liability
Drivers who routinely drop trailers and move the tractor alone to fuel, reposition, or head home
Operators whose lease agreement requires bobtail as a condition of leasing on
Carriers running under their own authority who insure the tractor around the clock generally do not need a separate bobtail policy.
How Coverage Is Structured
Bobtail is designed to sit around the motor carrier's primary liability, not on top of the same exposure:
It is usually written as a policy or endorsement for the owner-operator, often bundled with non-trucking liability
Limits are commonly a combined single limit in the range of $500,000 to $1,000,000 (illustrative)
The core trigger is "under dispatch" plus no trailer — coverage is intended for movement that is not the active hauling the primary policy covers
Primary liability and bobtail are meant to be mutually exclusive by trigger rather than stacked
Real-World Claim Examples
A driver delivers a load, unhooks at the receiver, and rear-ends a car while driving the empty tractor to a truck stop
After dropping a trailer, an owner-operator sideswipes a parked vehicle driving the tractor home
The tractor, running without a trailer between assignments, is involved in an at-fault intersection collision
Why Proper Placement Matters
The single biggest error in this class is confusing bobtail with non-trucking liability, so placement turns on:
The difference between bobtail (no trailer) and non-trucking liability (personal use) — a trip can be one, both, or neither
The fact that running empty to reposition for freight is business use, which primary liability, not bobtail, generally covers
Garaging location, driver age and record, truck type, radius, and requested limits
Whether the carrier blends bobtail and non-trucking liability into a single endorsement, since the exact definitions control
Because "under dispatch," "trailer attached," and "business use" are defined differently by different carriers, the coverage should be matched to the owner-operator's actual lease and movement patterns.
Regulatory & Contract Context
Bobtail is not a federal filing. The FMCSA requires the motor carrier to maintain primary liability, and under 49 CFR 376.12(c)(1) the lease must give the carrier exclusive possession, control, and use of the equipment for the duration of the lease. That exclusive-possession clause is why the carrier's primary policy attaches while the equipment is in the carrier's service — and why a gap appears when it is not. The regulation does not by itself allocate insurance responsibility, so the lease's own insurance provisions and the owner-operator's bobtail policy fill that role, and lease agreements commonly require bobtail at specified limits.
Our Approach
At Cory Washington & Co., we place bobtail coverage to match how an owner-operator actually runs — reading the lease, understanding when the tractor moves without a load, and confirming how the carrier defines "under dispatch" so there is no gap between primary liability and the off-load exposure. We coordinate it with non-trucking liability, physical damage, and cargo so the whole program fits together. We also insure related transportation businesses, including trucking companies, non-trucking liability, and truck repair shops.
Our goal is coverage that responds the moment the trailer comes off — not a claim denied over a definition.
