What is power only trucking?
Power only trucking is when a carrier supplies the tractor and driver, and the shipper, broker or another company supplies the trailer. You hook to a preloaded trailer, haul it, and drop it at the destination. It lets owner-operators haul freight without buying a trailer, but you need the right insurance for trailers you do not own.
Power only trucking is a simple idea: you bring the tractor and the driver, someone else brings the trailer. You hook to a loaded trailer, haul it to the receiver, drop it, and often pick up another trailer for the next run. For owner-operators who want to avoid buying and maintaining a trailer, it can be a smart way to get on the road.
How power only works
In a typical power only move:
- A shipper, broker or trailer owner has a loaded trailer waiting at a yard or dock.
- You book the load and get the trailer number, seal number and pickup details.
- You arrive, inspect the trailer, hook up and leave, often without waiting for a live load.
- You deliver and drop the trailer at the receiver or a designated yard.
- You may pick up an empty or loaded trailer to return or reposition.
Trailers can be dry vans, reefers, flatbeds or specialized units, depending on who owns them.
Who supplies the trailers
- Large carriers and leasing companies that have more trailers than trucks and need extra power.
- Brokers with trailer pools who offer power only loads to approved carriers.
- Shippers with their own trailers who keep trailers at their docks and hire outside tractors to move them.
- Rental and leasing trailers being repositioned from one location to another.
Each source has its own approval process, and some require a certain time in business, safety record or insurance limits.
Equipment you need
Power only does not mean no equipment. You still need a well-maintained tractor that can pull the trailers you plan to haul. Check:
- Fifth wheel in good shape and set at the right height
- Glad hands and air lines in working order
- Electrical connection (the 7-way plug) and working trailer lights
- Reefer fuel if you haul refrigerated trailers (find out who pays for it)
- Load locks or straps in case the trailer needs them
- A good flashlight and a checklist for trailer inspections at night
Insurance for power only
This is the area new power only carriers most often get wrong. Your standard policies cover your truck, your liability and the cargo. But if a trailer you do not own is damaged, you may be responsible for it.
Common coverage types to ask your agent about:
- Trailer interchange. Covers physical damage to a non-owned trailer when you have a written interchange agreement with the owner.
- Non-owned trailer physical damage. Covers damage to trailers you pull without a formal interchange agreement.
- Primary auto liability and cargo, at the limits the broker or trailer owner requires.
Which one you need depends on your contracts. Talk to your insurance agent and give them a copy of the agreements before you haul. For the basics, see trucking insurance explained.
Inspect every trailer before you leave
Since the trailer is not yours, document its condition every time:
- Walk around and photograph all sides, tires, doors and the seal
- Check tires, lights, brakes and the landing gear
- Confirm the seal number matches the paperwork
- Note any damage on the bill of lading or with the shipper before leaving
- Make sure the trailer registration and annual inspection are current
If you skip this, you may end up paying for damage that was there before you hooked up. Report problems before you roll, not after.
Rates and the money side
Power only rates are often somewhat lower than equivalent loads where you supply the trailer, because you are not providing the trailer. But your costs are lower too. Here is a hypothetical comparison for one month:
| Item (hypothetical) | With own trailer | Power only |
|---|---|---|
| Trailer payment | $800 | $0 |
| Trailer insurance and maintenance | $450 | $0 |
| Non-owned trailer coverage | $0 | $150 |
| Average rate per mile | $2.30 | $2.15 |
| Revenue on 9,000 miles | $20,700 | $19,350 |
| Revenue minus trailer-related costs | $19,450 | $19,200 |
In this example, the gap is small. The bigger advantages of power only are lower startup cash, no trailer repairs and quick drop-and-hook turns. Run your own figures in the cost per mile calculator.

- Prepare a complete carrier packet: authority, W-9, certificate of insurance and any interchange agreements.
- Apply with brokers and companies that offer power only freight, and ask about their requirements up front.
- Vet every broker before you haul. Our guide on how to vet a freight broker explains what to check.
- Track your profit per mile closely for the first few months.

Frequently asked questions
Do I need special insurance for power only?
Usually yes. Because you pull trailers you do not own, brokers and trailer owners often require trailer interchange or non-owned trailer physical damage coverage on top of your regular liability and cargo policies. Ask your insurance agent which fits your contracts.
Do power only loads pay less than dry van loads?
Often a bit less per mile, since you are not supplying the trailer. But you also avoid the trailer payment, insurance and maintenance, so compare profit per mile rather than the rate alone.
Can I start power only with a new MC number?
Yes, though some trailer pools and brokers require a minimum time in business or a safety record before they approve you. Expect a longer setup process than for standard loads.
