Non-Trucking Liability Insurance (NTL & Bobtail Coverage)
If you lease your truck to a motor carrier, there are hours when you are behind the wheel but not under a load and not working for the carrier. Driving home after you drop a trailer, running to the store on your day off, deadheading to pick up your next job. In those hours your carrier’s liability policy usually does not apply, and that gap is exactly what non-trucking liability insurance is built to close.
We are in trucking, not the insurance industry, so here is what you need to know: non-trucking liability (NTL) is the coverage most truckers are talking about when they say “bobtail” insurance. Below is what it covers, what it costs, who needs it, and how it is different from trucking liability insurance, the primary liability on your commercial truck insurance.

The short answer Non-trucking liability (NTL) insurance covers your truck when you drive it off-dispatch for personal use, in the moments your motor carrier’s primary liability does not apply. For a single truck with a clean record it runs about $45 to $125 a month ($550 to $1,500 a year). It is the coverage truckers often call “bobtail” insurance, and we write it as non-trucking liability. |
What non-trucking liability insurance covers
Non-trucking liability pays for bodily injury and property damage you cause to other people when you are driving your truck but not for the motor carrier you lease to and you have an owner operator lease agreement. Think of it as the liability coverage for your off-the-clock miles. The policies we place for leased owner-operators generally cover these situations:
- Personal use. Driving to the store, to the bank, or to visit family on a day you are not dispatched.
- Off-dispatch driving. Any time the truck is moving and you are not under a load or working for the carrier whose authority you run under.
- The gap your carrier leaves. A motor carrier’s primary liability typically only responds while you are working for them. NTL answers the rest of the time.
It is just as important to know what NTL does not do. It is liability coverage only, so it does not pay to repair your own truck (that is physical damage coverage), it does not cover your freight (that is cargo coverage), and it does not respond while you are under dispatch (that is the primary commercial auto liability your carrier files). NTL fills one specific gap and is priced to match.
Non-trucking liability vs. bobtail insurance: what’s the difference?
Short answer: they describe overlapping situations, and the industry uses the two terms loosely. The technical difference is when the truck is moving and why.
- Non-trucking liability covers personal, non-business use of your truck, outside of dispatch.
- Bobtail is the older term for driving the tractor with no trailer attached, often deadheading between loads.
In practice, most modern policies for leased drivers are written as non-trucking liability, and that is the coverage we place. When a motor carrier or a fellow driver tells you to “get bobtail,” what they almost always mean is the non-trucking liability policy below. We do not sell a separate “bobtail” product; we write non-trucking liability that covers those off-dispatch miles.
| Term | When it applies |
|---|---|
| Non-trucking liability (we write this) | Personal, off-dispatch driving, not under a load |
| Bobtail (a related term) | Driving the tractor with no trailer, between loads |
How much does non-trucking liability insurance cost?
Non-trucking liability is one of the cheapest policies in trucking because it only covers a narrow slice of your driving. For a single truck with a clean record, NTL on its own runs about $45 to $125 a month ($550 to $1,500 a year). Leased owner-operators often pair it with physical damage so their own truck is protected too, and that combined policy runs higher because physical damage is priced on the value of the truck.
| Coverage | Typical cost |
|---|---|
| Non-trucking liability (NTL) only | $45 to $125/mo ($550 to $1,500/yr) |
| NTL + physical damage (leased owner-op) | $45 to $500/mo ($550 to $6,000/yr) |
| Physical damage portion | 3% to 12% of the truck’s value per year |
A simple way to picture the physical damage piece: a truck worth $50,000 generally costs about $1,500 (3%) to $6,000 (12%) a year to cover. Your final number depends on your driving record, your radius, your truck’s value, and the limit your carrier requires. Get an exact rate rather than guessing from a range.
Who needs non-trucking liability insurance?
NTL is built for drivers who run under someone else’s authority. If that is you, your lease almost certainly calls for it. The drivers we write it for most often are:
- Leased owner-operators. You own the truck but pull for a motor carrier under their authority, and their liability only covers you under dispatch. See our owner-operator insurance page for the full picture.
- Drivers whose lease requires it. Many carrier lease agreements list non-trucking liability as a condition of pulling for them.
- Anyone driving the truck off the clock. If you use the truck for personal trips, NTL is what protects you when the carrier’s policy will not.
If you run under your own authority, you usually do not need NTL, because your own primary liability covers you full time. In that case the better starting point is a full commercial truck policy, not a non-trucking add-on.
Non-trucking liability requirements and limits
Non-trucking liability is not a coverage you file with the FMCSA. It is a contractual requirement that comes from your motor carrier’s lease, not a federal filing like primary liability. Your carrier sets the limit you have to carry, and a $1,000,000 combined single limit is the most common requirement we see. Always read your lease and match the limit it asks for. Carrying less can put you out of compliance with the carrier, and carrying far more than the lease requires just raises your premium for no reason.
How to get cheaper non-trucking liability insurance
NTL is already inexpensive, but a few things keep it that way:
- Keep your MVR clean. Your personal and commercial driving history still drives the price, even on a part-time coverage.
- Match the limit to your lease. Buy the limit your carrier requires, not more.
- Bundle NTL with physical damage. Writing both on one policy is usually cheaper and simpler than two separate ones.
- Pay annually when you can. Paying in full avoids finance charges that get added when a premium is financed.
- Use a trucking specialist. An agent who only works in trucking can place NTL with carriers that actually want it, instead of treating it as an afterthought.
Frequently asked questions
Is bobtail insurance the same as non-trucking liability?
For most drivers, yes, in everyday use. Technically, bobtail refers to liability while you drive the tractor with no trailer, and non-trucking liability refers to liability during personal, off-dispatch use. The two situations overlap, and modern policies for leased drivers are written as non-trucking liability. When someone tells you to “get bobtail,” they are almost always describing the NTL policy we write.
What is non-trucking liability insurance?
It is liability coverage for the times you drive your truck but are not working for the motor carrier you lease to, such as personal errands or driving home off-dispatch. It pays for injuries or property damage you cause to others during those off-the-clock miles, when your carrier’s primary liability does not apply.
How much is non-trucking liability per month?
For a single truck with a clean record, NTL on its own usually runs about $45 to $125 a month ($550 to $1,500 a year). If you add physical damage so your own truck is covered, the combined policy can run up to about $500 a month, because physical damage is priced at 3% to 12% of the truck’s value.
Is non-trucking liability the same as physical damage coverage?
No. Non-trucking liability pays for damage you cause to other people off-dispatch. Physical damage pays to repair or replace your own truck. They are often sold together for leased owner-operators, but they cover two different things.
Do I need NTL if I’m leased to a carrier?
Usually yes. Most carrier lease agreements require non-trucking liability, because their primary liability only covers you while you are under dispatch. Check your lease for the exact limit they require, commonly $1,000,000.
Can I get short-term or temporary non-trucking liability?
Often yes. Short-term non-trucking liability is common for drivers heading to orientation or covering a brief gap between carriers. Tell us your situation and we will place the shortest term that keeps you compliant with the carrier.
