Power Only Insurance Requirements
Running power only means hauling trailers you do not own — which creates unique insurance requirements. You need all the standard carrier coverages plus non-owned trailer insurance to protect yourself from liability for damage to someone else's trailer. This guide covers every policy you need, what it costs, and how to avoid costly coverage gaps.

O TruckingPower Only Insurance Requirements: What Coverage Do You Need? (2026)
Key Takeaways
- Non-owned trailer coverage is the policy that makes power only insurance unique — it covers damage to a shipper's or broker's trailer while it is in your custody.
- Primary liability ($750K FMCSA minimum, $1M for most brokers) and cargo insurance (usually $100K) are required regardless of trailer ownership.
- Because you do not own a trailer, you skip trailer physical damage coverage but add non-owned trailer coverage instead — a roughly $50-$100/month net savings versus standard trucking.
- Many brokers now require non-owned trailer or trailer interchange coverage on your Certificate of Insurance before they will book you.
- Expect total monthly insurance of about $820 to $1,810; always request live quotes from multiple trucking-specific insurers since rates vary widely.
Power Only Insurance Overview
Power-only carriers need the same baseline insurance that every motor carrier needs (liability and cargo), plus one additional policy that is specific to hauling equipment you do not own: non-owned trailer coverage. Some brokers also require trailer interchange insurance, which is a related but slightly different policy.
Here is the complete coverage stack for a power-only carrier:
| Coverage Type | Required? | Typical Limits | Monthly Cost |
|---|---|---|---|
| Primary Liability | Yes (FMCSA) | $750K-$1M | $600-$1,200 |
| Cargo Insurance | Yes (Brokers) | $100K | $40-$100 |
| Non-Owned Trailer | Highly Rec'd | $30K-$100K | $50-$150 |
| Physical Damage (Tractor) | If Financed | ACV of truck | $100-$300 |
| Bobtail / NTL | Recommended | $750K-$1M | $30-$60 |
Primary Liability Insurance
Primary liability is required by FMCSA for all motor carriers operating interstate. It covers bodily injury and property damage to others if you cause an accident. The FMCSA minimum is $750,000, but most brokers require $1,000,000 before they will book you.
Primary liability is the same whether you run power only or standard trucking. The trailer type or ownership does not change this requirement. Expect to pay $600-$1,200 per month depending on your driving record, experience, and location.
Cargo Insurance
Cargo insurance covers damage to the freight you are hauling. Even though you do not own the trailer, you are responsible for the cargo while it is in your care, custody, and control. If the freight is damaged during transit — whether from an accident, theft, or negligence — your cargo policy pays the claim.
Most brokers require $100,000 in cargo coverage as a minimum. Some high-value freight (electronics, pharmaceuticals) may require higher limits. Cargo insurance typically costs $40-$100 per month and is the same cost whether you run power only or standard trucking.
Non-Owned Trailer Coverage (The Key Policy)
This is the policy that makes power-only insurance unique. Non-owned trailer coverage (also called trailer interchange insurance or borrowed trailer coverage) protects you from financial liability if a trailer you are hauling — but do not own — is damaged while in your possession.
Without this coverage, if you back into a pole and dent a shipper's trailer, or if the trailer catches fire, or if it is damaged in an accident, you are personally liable for the repair or replacement cost. Trailers cost $25,000-$60,000 new. Even a moderate repair can run $5,000-$15,000.
Typical limits — $30,000 to $100,000 per trailer. Most brokers require at least $30,000; some require $50,000 or $100,000 for newer or specialized trailers.
Cost — $50-$150 per month depending on your coverage limits, deductible, driving record, and insurance provider. Some policies charge per trailer; others are blanket coverage for any non-owned trailer you haul.
Deductible — Typically $1,000-$2,500. Lower deductibles mean higher premiums. Choose a deductible you can afford to pay out of pocket if a claim occurs.
What it covers — Physical damage to the non-owned trailer from collision, fire, theft, vandalism, and weather events while in your custody. Does NOT cover mechanical breakdown, wear and tear, or pre-existing damage.
Non-Owned Trailer Insurance Is NOT Optional
Physical Damage Insurance (Your Tractor)
Physical damage coverage protects your own tractor from collision, comprehensive, fire, theft, and vandalism. This is the same policy whether you run power only or standard trucking — it covers your truck, not the trailer. If you have a loan or lease on your tractor, the lender will require physical damage coverage. If you own the truck outright, it is optional but strongly recommended for any truck worth over $20,000. Cost: $100-$300/month depending on truck value and your record. See our owner-operator insurance guide for details.
Total Insurance Costs for Power Only
Monthly Insurance Budget: Power Only Carrier
Power Only vs Standard Trucking Insurance Costs
The insurance cost difference between power only and standard trucking is modest but real:
Power only saves on trailer physical damage — Standard carriers need physical damage insurance on their trailer ($100-$200/mo). Power-only carriers do not, since they do not own a trailer.
Power only adds non-owned trailer coverage — This costs $50-$150/mo — generally less than trailer physical damage insurance on your own trailer.
Net difference — Power-only carriers typically save $50-$100/month on total insurance costs compared to standard trucking carriers. Not a huge difference, but it adds up over a year.

Common Power Only Insurance Mistakes
- Skipping non-owned trailer coverage to save $50-$150/month — one damaged trailer can cost you $15,000-$50,000+ out of pocket.
- Assuming cargo coverage protects the trailer. Cargo insurance covers the freight; trailer damage is a separate non-owned trailer or trailer interchange policy.
- Not matching your limits to the broker's requirement. Carrying $30,000 when a broker requires $100,000 non-owned trailer coverage will fail their Certificate of Insurance (COI) check.
- Letting coverage lapse. An insurance gap can suspend your FMCSA authority and cost you loads — track renewal dates closely.
- Buying from an insurer unfamiliar with power only. Confirm the policy specifically includes non-owned trailer coverage rather than assuming a standard trucking policy covers it.
How Our Team Verifies Insurance Compliance
At O Trucking LLC, we verify insurance on every carrier we dispatch:
Insurance verification before booking
Before we dispatch any power-only carrier, we verify that their Certificate of Insurance (COI) includes primary liability, cargo, and non-owned trailer coverage at the limits required by the broker. If your coverage has gaps, we identify them before they cause problems on a load.
Broker insurance requirement matching
Different brokers have different insurance requirements. Some require $50,000 non-owned trailer; others require $100,000. We match you with loads where your coverage meets the broker's requirements, avoiding booking rejections and compliance issues.
Renewal tracking
Insurance lapses are a common problem that can shut down your authority. We track your policy renewal dates and remind you before they expire, so you never have a gap in coverage that could cost you loads or trigger FMCSA enforcement.

Frequently Asked Questions
Do power only carriers need their own trailer insurance?
No. Because power only carriers do not own the trailers they pull, they do not need trailer physical damage insurance on an owned unit. Instead, they need non-owned trailer coverage (often called trailer interchange) to protect against liability for damage to a trailer that belongs to a shipper, broker, or trailer pool while it is in their custody.
Is non-owned trailer coverage the same as trailer interchange insurance?
They overlap but are not identical. Trailer interchange insurance applies when you pull a trailer under a written interchange agreement. Non-owned trailer coverage is broader and can apply whether or not a formal interchange agreement exists. Many trucking insurers bundle both concepts into one endorsement, so ask your agent exactly which trigger your policy uses and confirm it matches how your broker assigns trailers.
How much does power only insurance cost per month?
Total monthly insurance for a power only owner-operator generally runs from a few hundred dollars up to roughly $1,800 once you add primary liability, cargo, non-owned trailer coverage, and bobtail. The single largest line item is primary liability, which is driven by your driving record, experience, equipment value, and operating area. Always request live quotes from at least two or three trucking-specific insurers, since rates vary widely.
Will brokers reject a power only carrier without non-owned trailer coverage?
Increasingly, yes. Many brokers and shippers now list non-owned trailer or trailer interchange coverage as a condition on their carrier packet, and their Certificate of Insurance (COI) check will flag a missing endorsement. Even when it is not strictly required, carrying it protects you from a five-figure repair bill if the trailer is damaged in your custody.
