Bobtail liability insurance covers a commercial truck when it is being operated without its normal trailer load, usually outside normal hauling operations.
Underwriting and scope
This is a specialized auto liability form. Underwriters look at vehicle age, mileage, operation pattern, and use restrictions because risk is different when a vehicle is running light.
Claims treatment
Claims follow standard liability principles for bodily injury and property damage, but the policy schedule and endorsement language define which exposures are covered and which are excluded.
Operational significance
For fleets, this coverage protects owner-operators during maintenance moves, deadheading, or return to base, especially when the trailer is not attached.
