What Is Power Only Trucking? How to Get Power Only Loads

Power only trucking means you bring the tractor and someone else provides the trailer. No trailer payment, no trailer repairs, and a lot of drop and hook freight. It's a smart way to start or to cut costs, but it depends on trailer pools near you and on carrying the right insurance. Here's how it works and how to get your first loads.

What power only trucking is

In power only, the carrier supplies the power unit (the tractor) and a driver. The trailer belongs to a broker's trailer pool, a shipper or another carrier. You hook to a trailer that's already loaded or waiting, haul it to its destination, and drop it.

It grew as shippers and large brokers built trailer pools to move freight without waiting on a carrier that owns the right trailer. For an owner-operator, it means you can haul van and sometimes reefer freight without buying the trailer.

How power only loads work

1. The broker or shipper has a trailer at a shipper location, a drop yard or a distribution center.
2. You book the load through the broker's power only program or a load board.
3. You hook and inspect. Check the trailer and the seal, sign the paperwork and go.
4. You drop at the receiver. Often you pick up an empty or another loaded trailer for your next move.

Because most of it is drop and hook, you usually spend less time waiting at docks than on live loads. When a pickup does turn into a long wait, detention still applies if it's on the rate confirmation. Here's how to collect detention.

Pros and cons

The insurance you'll need

On top of auto liability and cargo, power only programs almost always require coverage for the trailer you're pulling:

• Trailer interchange. Covers damage to a trailer you pull under a written interchange agreement, the usual arrangement in broker trailer pools.
• Non-owned trailer coverage. Covers trailers you don't own when there's no interchange agreement.

Programs set their own limits, so ask each broker what they require before you buy. Get the limits on your certificate of insurance in writing, and make sure the cargo policy covers the freight types you'll pull. Our new authority insurance guide covers the rest.

How to get approved for power only programs

Large brokers that run trailer pools usually have their own onboarding for power only carriers. Expect them to check:

• Active authority, and sometimes a minimum time in business
• Liability, cargo and trailer interchange limits on your certificate
• Your safety record and inspection history
• Your tractor's details, ELD and tracking capability
• A signed program agreement covering trailer use and damage

Read the program agreement closely. It spells out who pays for trailer damage, tire and light repairs, and what happens if a trailer is late back to the pool.

Questions to ask a power only program

• What trailer interchange or non-owned trailer limits do you require?
• Who pays for tires, lights and minor repairs on your trailers?
• How do I report damage I find at pickup, and how fast do you respond?
• Are there fees if a trailer is returned late or to the wrong yard?
• How are detention and layover handled on drop and hook loads that turn into live loads?
• How often do you have loads out of the pools near my home base?

Inspecting a trailer you don't own

Every pool trailer is new to you, and federal rules (49 CFR 396.13) make you responsible for being satisfied it's in safe operating condition before you drive. Before you leave the yard:

1. Walk around it: tires, lights, mud flaps, landing gear, doors and roof.
2. Check the brakes and air lines once hooked.
3. Confirm the seal number matches the paperwork.
4. Photograph any existing damage, with a timestamp.
5. Report problems to the broker before you leave, and get a swap or written acknowledgment.

That five-minute check is what keeps old damage from being charged to you, and what keeps you from being placed out of service for a defect that was there before you hooked.

Keep a simple log of every trailer you pull: the trailer number, the pool or program, pickup and drop times, and photos. If a damage claim or late-return fee shows up weeks later, the log is how you prove what you were handed and when you returned it.

What power only pays

There's no reliable national benchmark for power only rates. Rates often run a little under van rates on the same lane, since you're not providing the trailer, but it depends on the program, the lane and how urgently the trailer needs to move. Compare every offer to what your truck costs to run per mile, not to someone else's.

The economics can still beat owning a trailer. With no trailer payment, insurance or maintenance, your cost per mile is lower, so a slightly lower rate can leave you with similar or better net pay.

How to get your first power only loads

• Find the pools near you. Distribution centers, retail and manufacturing hubs are where trailer pools concentrate, such as the warehouse belts around Atlanta and Dallas-Fort Worth.
• Get set up with the programs that run them, before you need a load.
• Filter load boards for power only.
• Plan the reload. After you drop, there's often a trailer to take back or reposition. That's your best backhaul.

Our power only dispatch service handles program setup with brokers, maps the pools near your home base and lines up your next trailer before you drop, for a flat 6% of the gross. Pulling van trailers most of the time? Our reefer vs dry van comparison shows how those markets differ.
