Non-Trucking Liability (NTL).
Bobtail coverage protecting an owner-operator leased on with a carrier when driving the truck for personal/non-business use.
What it is
Non-trucking liability (NTL) — commonly called "bobtail" insurance — is coverage specifically for owner-operators leased on with a motor carrier under a permanent lease. It covers the truck when not under dispatch: personal use, between loads, or traveling to and from home. The name "bobtail" originally referred to running the tractor without a trailer, but NTL is the underwriting label.
The motor carrier's primary liability covers the truck only when it is under dispatch — meaning a load is assigned and the run is active. Without NTL, an at-fault accident on a non-dispatch trip could be entirely uninsured, leaving the owner-operator personally liable for BI and PD damages. Cost is typically $300–$700 per year for owner-operators, and most carriers require NTL as a contractual condition of leasing on. The coverage is narrow but addresses a real gap that catches first-time lease-on operators off-guard. The distinction between "under dispatch" and "not under dispatch" is contractual and audited by the carrier after any claim.
Why it matters for trucking finance
NTL is one of the most misunderstood coverages — many lease-on owner-operators assume the carrier's primary covers them at all times. It does not. The gap between dispatch and non-dispatch periods creates personal liability exposure that an at-fault accident can convert into a life-altering claim, especially because the truck is the operator's largest asset and personal liability follows them home.
Lenders evaluating lease-on owner-operators sometimes verify NTL is in place as a sign of operational discipline. For independent owner-operators with their own MC#, NTL is unnecessary — primary liability covers all use regardless of dispatch status.
