Non-trucking & Bobtail Liability Insurance
Protection when the rig Is off the clock
Non-Trucking Liability (NTL), also known as Bobtail Liability, provides coverage for bodily injury and property damage when an insured truck is operated for personal or non-business purposes. For example, when dead-heading to a repair shop or driving home after the last delivery. It fills the gap where a motor carrier’s primary auto liability policy ends.
Coverage
Situation | How the policy responds |
|---|---|
Personal errands | Pays third-party claims if an accident occurs while the tractor is being driven off-dispatch (for fuel, food, or home). |
Dead-Head / No trailer | Covers liability while traveling bobtail to pick up the next load or returning to base without a trailer. |
Lease-required gap | Satisfies the lease clause that obligates an owner-operator to carry liability coverage whenever the carrier’s policy isn’t in force. |
Not covered: on-dispatch trips, freight hauling, or activities that generate business revenue. Those exposures remain under the motor carrier’s primary auto liability policy.
