What non-trucking liability covers
When an owner-operator leases a truck to a motor carrier, the carrier's auto liability policy covers the truck while it is operating in the carrier's business, which usually means while it is under dispatch. Non-trucking liability (NTL) covers your liability for injury and property damage the rest of the time, when you are using the truck for purposes that are not the carrier's business.
Typical NTL situations are driving the truck home at the end of a run after you have been released, a personal errand in the tractor on a day off, or driving to a family event. In each case the carrier's policy is unlikely to respond, and without NTL you are personally exposed.
Non-trucking liability vs bobtail insurance
The terms get used interchangeably, but they are not the same thing:
- Non-trucking liability is defined by purpose. It applies when the truck is not being used in the business of the motor carrier, with or without a trailer.
- Bobtail coverage, in its original sense, is defined by equipment. It applies when the tractor is driving without a trailer, and some bobtail forms apply even when that trip is business-related, such as deadheading to pick up a load.
Many insurers now sell NTL and call it bobtail, and many leases say "bobtail" when they mean NTL. Ask which one the policy actually is, and compare its wording to what your lease requires.
Who needs it, and what the lease requires
If you are leased on, you almost certainly need NTL. Most lease agreements require it, name the limit (commonly $1,000,000 combined single limit, sometimes less), and require you to name the motor carrier as an additional insured or certificate holder. The carrier will ask for a certificate before your first load.
If you run under your own authority, you do not need NTL. Your own primary auto liability policy covers you at all times. See our guide to FMCSA insurance requirements for what that policy has to include.
What non-trucking liability costs
NTL is inexpensive because the exposure is limited to non-business use. As an illustrative range, it often costs from a few hundred dollars to around a thousand dollars a year per truck at a $1,000,000 limit. Your driving record, garaging location and how the truck is used outside of dispatch move it within that range. Some motor carriers offer NTL through their own program and deduct it from your settlements; compare that price to buying it yourself.
The gray areas behind denied claims
Most NTL disputes are about whether a trip was "in the business of the motor carrier." If it was, the carrier's policy should respond and NTL will not. If it was not, the reverse. The hard cases sit in between:
- Driving to the shop or truck wash. Maintenance trips are often argued to be business use. Many NTL forms exclude them.
- Driving home after a delivery. If the carrier has not released you, the trip may still count as dispatch.
- Heading to pick up a load. Generally business use under the carrier's policy, not NTL.
- Hauling for another company. Using the truck for anyone else's business is typically excluded under both policies, and a lease may forbid it.
Keep clear records: dispatch logs, release times, and ELD data. They decide which policy pays.
Before you sign a lease: what to check
- The required NTL limit and whether the motor carrier must be named as additional insured or only as certificate holder.
- Who pays for what. Some leases charge you for the carrier's liability coverage or for cargo deductibles through settlement deductions. Know the numbers before you start.
- When dispatch ends. The lease or the carrier's policy should define when you are released. That moment decides which policy covers the drive home.
- Physical damage requirements, including the minimum value and any loss-payee requirement for a lender.
- Occupational accident: whether the carrier requires it, the minimum benefits, and whether it can be bought through the carrier's program.
- Trip leasing and other work. Whether you may haul for anyone else, which most leases forbid while you are under the carrier's authority.
What NTL does not cover
- Your truck. NTL is liability only. You need physical damage coverage for the tractor and any trailer you own.
- Your own injuries. Owner-operators often carry occupational accident insurance, which many motor carriers require in place of workers' compensation.
- Cargo. Freight is covered by the motor carrier's motor truck cargo policy while you are under its dispatch.
IMD writes NTL, physical damage and occupational accident for leased owner-operators, and can read your lease to confirm what it requires. See the trucking insurance page or call (332) 333-2353.
Frequently asked questions
What is non-trucking liability insurance?
Liability coverage for a leased owner-operator's truck when it is not being used in the motor carrier's business, such as personal use after being released from dispatch. The carrier's own policy covers the truck while it is under dispatch.
Is non-trucking liability the same as bobtail insurance?
Not exactly. NTL applies based on purpose, when the truck is not in the carrier's business. Bobtail originally applied based on equipment, when the tractor runs without a trailer. Many insurers sell NTL under the bobtail name, so check the wording.
How much does non-trucking liability cost?
Often from a few hundred dollars to around a thousand dollars a year per truck at a $1,000,000 limit, depending on driving record, garaging and how the truck is used.
Do I need NTL if I have my own authority?
No. A carrier running under its own authority carries primary auto liability that covers the truck at all times. NTL is for owner-operators leased to another carrier.
