What Is Bobtail Insurance? A Complete Guide for Truckers

Bobtail insurance covers your truck cab when driving without a trailer and without being under dispatch. Learn what it covers, what it costs, and whether you need it.

If you’re an owner-operator leased to a carrier, you’ve probably been asked to carry bobtail insurance. But what exactly does it cover — and why isn’t it included in your regular commercial auto policy? This guide explains everything you need to know.

What Is Bobtail Insurance?

Bobtail insurance covers your semi truck cab when you’re driving it without a trailer attached and you’re not under dispatch — meaning your carrier’s liability coverage does NOT apply at that moment.

The term “bobtailing” comes from the image of a truck driving around with its tail cut off — just the tractor, no trailer. Common bobtail situations include:

  • Driving home from a drop point after delivering a load
  • Heading to a fuel stop or truck wash between loads
  • Repositioning the cab to pick up a different trailer
  • Personal use between dispatch assignments

Bobtail vs. Non-Trucking Liability: What’s the Difference?

These two terms are often confused and sometimes used interchangeably, but there’s an important distinction:

Bobtail insurance covers the cab specifically when operating without a trailer, regardless of whether you’re under dispatch.

Non-trucking liability (NTL) covers the truck for personal use and other situations when you’re NOT under dispatch — whether you have a trailer attached or not.

In practice, most insurance carriers use “bobtail” and “non-trucking liability” to mean roughly the same product: liability coverage for when you’re operating outside of your motor carrier’s authority. Always read the policy definition carefully — some policies cover the cab only when bobtailing, others cover all non-dispatched use.

Why Your Carrier’s Policy Doesn’t Cover You When Bobtailing

When you’re leased to a carrier and operating under their DOT authority, the carrier’s primary liability insurance covers accidents you cause. However, that coverage is tied to active dispatch — it only applies when you’re hauling a load on their behalf.

The moment you drop a load and drive away without a new dispatch, the carrier’s coverage stops. If you get into an accident driving back to the truck stop, you could be personally liable for hundreds of thousands of dollars in damages.

This is exactly the gap that bobtail insurance fills.

What Does Bobtail Insurance Cover?

Bobtail insurance is a liability coverage — it pays for damages you cause to other people and property during covered operations. It typically includes:

  • Bodily injury liability — medical expenses, lost wages, and pain and suffering for people injured in an accident you cause
  • Property damage liability — repairs or replacement of other vehicles and structures you damage

What bobtail insurance generally does not cover:

  • Damage to your own truck (you need physical damage coverage for that)
  • Cargo in transit (motor truck cargo coverage handles that)
  • Injuries to yourself (occupational accident or health insurance)
  • Operations while under dispatch (the carrier’s policy covers this)

Who Needs Bobtail Insurance?

You need bobtail insurance if all three of the following apply to you:

  1. You own your truck (or are purchasing it under a lease-purchase agreement)
  2. You’re leased to a carrier under their DOT authority
  3. You operate your truck when not under dispatch — driving home, going to fuel, repositioning

If you’re an independent owner-operator with your own DOT authority, you don’t have a carrier’s policy to fill the gap — you need your own full primary liability policy instead. Bobtail is for leased operators specifically.

How Much Does Bobtail Insurance Cost?

Bobtail insurance is one of the most affordable commercial trucking coverages:

Coverage LevelTypical Annual Cost
$750,000 liability limit$350 – $600 / year
$1,000,000 liability limit$500 – $800 / year
$2,000,000 liability limit$700 – $1,200 / year

Monthly cost typically runs $30–$70 per month — a small price for significant protection. Rates depend on your driving record, years of CDL experience, location, and the carrier you’re leased to.

What Limit Should You Carry?

Most carriers require leased owner-operators to carry a minimum of $750,000 in bobtail liability as a condition of their lease agreement. This matches the FMCSA minimum for interstate carriers.

However, $1,000,000 is strongly recommended and is the standard for most experienced owner-operators. Given that a serious accident involving injuries can easily generate claims exceeding $750,000, the difference in premium ($150–$200/year) is well worth it.

Some carriers require $1,000,000 minimum in their lease contracts — check yours before purchasing.

Does Your Lease Agreement Require Bobtail Insurance?

Yes, in almost every case. Most motor carrier lease agreements explicitly require owner-operators to maintain bobtail or non-trucking liability insurance as a condition of operating under their authority.

If you can’t show proof of bobtail coverage, most carriers won’t allow you to park or operate their equipment on company property, and they may terminate the lease.

Read your lease carefully. The required limits and covered operations are typically specified in the insurance section of the contract.

Is Bobtail Insurance Required by FMCSA?

No — the FMCSA does not specifically mandate bobtail insurance. The FMCSA requires carriers to maintain minimum primary liability coverage, but bobtail coverage for leased operators is a private contractual requirement between you and your carrier, not a federal regulation.

That said, operating without bobtail insurance while bobtailing puts you at personal financial risk that is disproportionate to the small cost of coverage.

How to Get Bobtail Insurance

Bobtail insurance is available through most commercial truck insurance carriers. Because it’s a narrow coverage (not a full commercial auto policy), it’s usually purchased as an add-on to your physical damage policy rather than as a standalone.

Steps to purchase:

  1. Contact commercial truck insurance agents or carriers
  2. Provide your CDL information, years of experience, and driving record
  3. Provide the name of the motor carrier you’re leased to
  4. Specify the required limits from your lease agreement
  5. Request quotes from at least 2–3 carriers

Some carriers that offer bobtail/non-trucking liability to owner-operators include Progressive Commercial, Great West Casualty, Canal Insurance, and National Liability & Fire.

Common Questions About Bobtail Insurance

Does bobtail insurance cover a load I’m hauling on a spot market? No. If you pick up a load under your own authority (not your carrier’s), you need your own primary liability — not bobtail insurance.

What if I drive a personal vehicle, not the truck? Bobtail insurance only covers the commercial truck. Your personal vehicles are covered under your personal auto policy.

Can I use my truck for personal errands? This depends on your specific policy. Non-trucking liability policies often cover personal use; some bobtail policies do not. Read your policy’s “covered operations” definition carefully.
