What Is Power Only Trucking?
Power only trucking is an arrangement where a carrier provides only the tractor — the power unit — to haul a trailer owned by a broker, shipper, or third-party company. This guide covers exactly how power only works, who uses it, and when it makes sense for your business.

O TruckingWhat Is Power Only Trucking? Complete Guide for Carriers (2026)
Power Only Trucking Defined
Power only trucking is exactly what the name says — the carrier provides only the “power” (the tractor, cab, or truck) to move a trailer. The trailer itself belongs to someone else. The carrier never owns, leases, or takes long-term responsibility for the trailer. They hook up, haul it to the destination, unhook, and move on.
This is fundamentally different from standard trucking, where the carrier provides the complete combination: tractor and trailer. In standard trucking, the carrier owns or leases the trailer, maintains it, insures it, registers it, and keeps it between loads. In power only, all trailer-related responsibilities stay with the trailer owner.
The term “power only” has been around for decades, but the model has grown significantly in the last 5-10 years. E-commerce growth has driven major shippers (particularly Amazon, Walmart, and Target) to invest heavily in their own trailer fleets. They have the trailers — they just need someone with a truck to move them. This creates a steady and growing supply of power-only freight across the country.
Power only is also used for trailer repositioning — moving empty trailers from where they were delivered back to where they are needed. Large retailers and leasing companies constantly need to rebalance their trailer fleets across their distribution network, creating additional power-only volume that carriers can take advantage of.
Power Only Goes by Many Names
How Power Only Works: Step by Step
The power-only workflow follows a predictable pattern. Here is each step in detail:
Load Gets Posted as Power Only
A broker, shipper, or logistics company posts a load on a load board or contacts carriers directly. The listing specifies “power only” as the equipment type, meaning the carrier does not need to provide a trailer. The listing includes pickup and delivery locations, the trailer number, trailer type (dry van, reefer, flatbed), and the rate.
Carrier Negotiates and Accepts the Load
The carrier reviews the load, negotiates the rate if possible, and accepts. The broker sends a rate confirmation that includes the agreed rate, pickup/delivery details, the specific trailer number, and any special instructions. The carrier should verify the broker's credit score before accepting.
Hook to the Trailer and Pre-Trip Inspect
At the pickup location, the driver finds the designated trailer (identified by trailer number), hooks the tractor to it, and performs a thorough pre-trip inspection. This includes checking tires, brakes, lights, coupling devices, and overall trailer condition. If the trailer has issues, the driver should document them and notify the broker before departing. Refusing an unsafe trailer is the driver's legal right and responsibility.
Transport and Deliver
The carrier hauls the trailer to the delivery location following the same rules of the road as any other shipment — compliance with hours of service, ELD logging, and weight limits. At delivery, many power-only loads are drop-and-hook: the driver drops the trailer at the designated spot and either hooks to a new trailer or leaves without one.
Submit Paperwork and Get Paid
After delivery, the carrier submits the signed bill of lading, proof of delivery, and invoice to the broker. Payment follows the broker's standard terms — typically Net 30. Carriers who need faster payment can use factoring or QuickPay if available.
Who Uses Power Only?
Power only involves multiple parties on both the supply and demand side:
Large Shippers with Trailer Fleets
Companies like Amazon, Walmart, Target, and Costco own thousands of trailers but rely on carriers to provide tractors and drivers. Amazon Relay is one of the largest sources of power-only freight in the country, consistently posting loads where carriers hook to Amazon-owned trailers.
Trailer Leasing Companies
Companies like XTRA Lease, Stoughton, and Great Dane Leasing manage massive trailer fleets that need to be repositioned between locations. When a trailer is sitting in Dallas but needed in Atlanta, they post a power-only load to move it.
Freight Brokers
Many brokers arrange power-only shipments on behalf of their shipper clients. Large brokerages like Coyote, Echo, XPO, and C.H. Robinson handle significant power-only volume. Brokers often post power-only loads when a shipper's trailer needs to be moved and the shipper does not have in-house drivers available.
Owner-Operators and Small Carriers
On the carrier side, power only is popular with owner-operators who do not own a trailer, new carriers getting started with minimal capital, and carriers between trailers (sold one, waiting on a new one). Some carriers run power only exclusively; others mix it with standard freight.
Trailer Ownership Arrangements in Power Only
Understanding who owns the trailer matters because it affects liability, insurance requirements, and what happens if the trailer is damaged:
| Trailer Owner | How It Works | Carrier's Risk |
|---|---|---|
| Shipper-Owned | Shipper owns and maintains the trailer. Carrier hooks and hauls. | Liability for damage while in your custody. Need non-owned trailer insurance. |
| Broker-Controlled | Broker arranges access to a leased or pool trailer. Common with large brokerages. | Same liability for damage. Broker may have specific insurance requirements. |
| Leasing Company | Trailer leasing firm needs the trailer repositioned. Often empty moves. | Standard liability. Leasing company handles trailer maintenance and registration. |
| Third-Party Pool | Shared trailer pool (like TPIC) where trailers are available at multiple locations. | Must follow pool rules. Damage liability applies per pool agreement. |
Always Confirm Trailer Ownership Before Accepting
Power Only vs Standard Trucking
The fundamental difference is simple: in standard trucking you provide the full rig; in power only you provide only the truck. But this one difference creates a cascade of operational, financial, and strategic differences:
- Capital investment — Power only requires $0 for trailer purchase vs $25,000-$60,000 for standard
- Monthly overhead — Power only saves $800-$1,500/month in trailer-related costs
- Revenue — Power-only rates are typically 10-20% lower than standard trucking rates
- Load flexibility — Standard carriers can haul any compatible load; power-only carriers need specific power-only postings
- Backhaul options — Standard carriers can find return freight easily; power-only carriers leave the trailer and need another power-only load or deadhead
- Trailer condition — In standard trucking, you control trailer quality; in power only, you get whatever trailer the shipper or broker provides

When Does Power Only Make Sense?
Power only is not for everyone, but it is the right choice in several common situations:
You are a new owner-operator with limited capital — If you just bought a truck and cannot afford a trailer right away, power only lets you start earning immediately while you save up for a trailer.
You want to test the owner-operator business model — Power only is a lower-risk way to try running your own authority without the full investment of tractor plus trailer.
Your trailer is in the shop — If your trailer needs extended repairs, power only keeps you earning while it is out of service rather than sitting idle.
You want equipment flexibility — Power only lets you haul dry van one day, reefer the next, and flatbed after that — all without owning multiple trailers.
You run lanes with high power-only volume — If you operate in corridors with Amazon fulfillment centers, Walmart DCs, or major distribution hubs, power-only loads may be abundant and consistent.
Common Power Only Mistakes to Avoid
Skipping the pre-trip inspection — Just because you do not own the trailer does not mean you can skip inspecting it. DOT holds the driver responsible. Check tires, brakes, lights, and coupling every time.
Not carrying non-owned trailer insurance — If you damage a trailer you do not own without proper insurance, you are personally liable for repair or replacement costs that can reach $50,000+.
Not planning the next load before delivery — After you drop the trailer, you have no trailer for a return load. Start searching for your next power-only pickup before you deliver. Do not wait until you are sitting with no trailer and no load.
Accepting loads without verifying the broker — Power-only loads are still subject to broker payment risk. Check the broker's credit score before accepting every load — the same as any other freight.
Comparing gross rates instead of net profit — A standard load at $2.80/mile is not necessarily better than a power-only load at $2.30/mile. Compare profit after all expenses, including trailer costs.

How Our Team Dispatches Power Only Carriers
At O Trucking LLC, we work with both power-only and full-service carriers:
Dedicated power-only load sourcing
We search DAT, Truckstop, Amazon Relay, and our broker network to find power-only loads on your preferred lanes. We know which brokers consistently post power-only volume and which lanes offer the best rates for power-only carriers.
Next-load planning to minimize deadhead
The biggest challenge in power only is avoiding unpaid deadhead miles after dropping a trailer. We start searching for your next load before you deliver the current one, so you have a pickup waiting near your drop location.
Full broker vetting on every load
Every power-only load goes through our standard broker verification process — checking authority, credit score, days to pay, and complaint history. We do not let our carriers haul for unvetted brokers, regardless of how the load is structured.
