The short answer
When you're leased on to a motor carrier, you run under their authority and their primary liability (and often cargo) policy; you usually need your own non-trucking liability, physical damage and occupational accident. When you run under your own authority, you need the full stack: primary liability, cargo, physical damage, general liability and federal filings. The cost, the paperwork and the risk shift onto you.
"Should I get my own authority?" is one of the biggest decisions an owner-operator makes, and insurance is a big part of it. The coverage you need, who pays for it and what happens after a claim all change when you move from a lease to your own MC number. This guide compares leased-on vs. own-authority insurance side by side, so you can see what you'd be taking on and budget for it honestly.
What "leased on" actually means
When you lease your truck to a motor carrier, you haul under that carrier's USDOT number and operating authority. Federal leasing rules (49 CFR Part 376) require a written lease that spells out, among other things, who is responsible for insurance and what can be charged back to you. The carrier is responsible for the operation of your truck while it's under dispatch, which is why its primary liability policy covers you on their loads.
What "own authority" means
With your own authority, you're the motor carrier. You hold an MC number, you contract directly with brokers and shippers, and you must have insurance filed with FMCSA before your authority becomes active. Every coverage requirement falls on you. See our new authority insurance guide for the full checklist.
Side-by-side: coverage you need in each case
| Coverage | Leased on | Own authority |
|---|---|---|
| Primary auto liability | Usually provided by the carrier | Required; you buy it and file it with FMCSA |
| Motor truck cargo | Usually the carrier's (check your lease) | Required by most brokers and shippers |
| Physical damage | You, especially if the truck is financed | You |
| Non-trucking liability / bobtail | You, usually required by the carrier | Not needed; your primary liability covers non-business use when written that way |
| Occupational accident | Often required by the carrier for independent contractors | Optional but strongly worth considering |
| General liability | Rarely | Often required by shippers and some brokers |
| Trailer interchange | Depends on the carrier | Needed if you pull others' trailers under interchange agreements |
| Federal filings (BMC-91X, BOC-3) | Not your responsibility | Required |
Non-trucking liability vs. bobtail: the coverage leased drivers get wrong
When you're leased on, the carrier's liability usually covers you while you're under dispatch. When you're not under dispatch, like driving home for the weekend or taking the truck to a personal errand, you need your own liability coverage. That's what non-trucking liability covers. "Bobtail" is often used interchangeably, but technically bobtail insurance can cover driving without a trailer even while under dispatch, depending on the policy. The difference matters in a claim. Our non-trucking liability and bobtail page explains how insurers draw that line.
Tip: Ask your carrier for a written description of when its liability policy applies and when it stops. Then make sure your non-trucking policy picks up exactly where theirs ends.
Chargebacks: what leased drivers actually pay
Even when the carrier provides primary liability and cargo, the cost often shows up on your settlement as an insurance chargeback, and your lease may make you responsible for a deductible after a claim. That's legal if the lease discloses it. Read the insurance section of your lease carefully:
- What insurance does the carrier provide, and what's the weekly or per-load charge?
- What deductible are you responsible for after a liability or cargo claim?
- Can the charge change during the lease, and how much notice do you get?
- Are you required to buy specific coverage from a specific provider?
The real cost difference
Owner-operators are often surprised by how much insurance costs under their own authority, especially in year one. A new authority has no loss history, and the full stack of coverages and filings adds up. We won't quote numbers that can't be verified for your situation, but the general pattern is consistent:
- Leased on: lower insurance outlay, because the carrier's fleet policy covers the expensive liability piece; you pay for physical damage, non-trucking and occupational accident, plus any chargebacks.
- Own authority: higher outlay, because you carry primary liability and cargo yourself, plus general liability and filings, at new-venture pricing until you build history.
Our truck insurance cost guide breaks down what drives each line.
What changes after a claim
Under a lease, a liability claim goes on the carrier's loss runs, though you may pay a deductible and the carrier may decide not to keep you on. Under your own authority, the claim goes on your loss runs and affects your renewal pricing for years. That's a big difference in who carries the long-term risk.
When getting your own authority makes sense
- You have steady broker or shipper relationships and confidence in your lanes
- You've budgeted for a down payment on the first policy and some months of premium
- You're ready to handle FMCSA filings, UCR, IFTA, and compliance yourself
- You have a plan for cash flow while brokers pay in 30 to 60 days, such as freight factoring
When staying leased on may be smarter
- You're early in your career and still building a clean record
- You'd rather focus on driving than on compliance and sales
- The lease terms are fair and the settlements are transparent
- You don't yet have the cash cushion to absorb a first-year policy and slow-paying brokers
A transition checklist if you're moving to your own authority
- Apply for your MC number and confirm your USDOT details (MC vs. DOT number)
- Line up a process agent for your BOC-3
- Get quotes for primary liability, cargo, physical damage and general liability at least a few weeks ahead
- Have your insurer file the BMC-91X once you bind coverage
- Cancel non-trucking liability only when your new primary liability starts, so there's no gap
- Register for UCR and set up IFTA if you'll cross state lines
- Set up factoring or a cash buffer for the first 60 days of receivables
Questions truckers ask
What insurance do I need if I'm leased on to a carrier?
Usually physical damage on your truck, non-trucking liability for when you're not under dispatch, and often occupational accident. The carrier typically provides primary liability and often cargo, but check your lease.
Is bobtail the same as non-trucking liability?
They're often used interchangeably, but they can differ. Non-trucking liability covers you when you're not under dispatch; bobtail may cover driving without a trailer even while dispatched. Check the policy wording.
Is insurance more expensive with my own authority?
Generally yes, especially in the first year, because you carry primary liability and cargo yourself with no loss history.
Who pays if I have an accident while leased on?
The carrier's liability policy usually responds while you're under dispatch, but your lease may require you to pay a deductible. Your physical damage policy covers your own truck.
Do I still need non-trucking liability with my own authority?
Usually not. Your primary liability policy can cover both business and personal use when it's written that way. Confirm with your agent.
