What Is Power Only Trucking Loads Rates and How It Works
A tractor sitting idle earns nothing, but pairing it with someone else's trailer can keep it moving and paid. Power only trucking lets a carrier haul loads without owning the trailer, which lowers the cost of entry and keeps equipment productive. This guide covers what power only trucking is, how the loads and rates work, and how carriers keep tractors earning.
Key takeaways

What is power only trucking?
Power only trucking is when a carrier supplies just the tractor, the power unit, to move a trailer owned by someone else. The shipper, broker, or a trailer pool provides the loaded or empty trailer, and your truck and driver do the pulling.
It is common in drop-and-hook operations, retail distribution, and trailer-pool networks where trailers stage at facilities waiting for a tractor. You bring the horsepower, they bring the box.
How power only loads work
A power only load follows a simple pattern, but the details around trailer condition and interchange matter. Knowing the flow keeps you from surprises at pickup.
You accept a power only load through a broker, load board, or dedicated program
You drive to where the trailer is staged, often a distribution center or yard
You hook to the pre-loaded trailer and complete an interchange agreement
You haul it to the destination and drop it, then repeat
The interchange agreement matters because it governs liability for the trailer while it is in your possession. Confirm the condition at hookup so a pre-existing issue does not land on you.
Power only rates and what drives them
Power only rates are quoted per mile or as a flat rate for the move, and they sit in a different cost structure than pulling your own trailer. You save on trailer ownership but the rate reflects that.
Factor | Effect on the rate |
Deadhead to the trailer | Empty miles cut into profit fast |
Lane and freight demand | Tight capacity lifts the rate |
Drop-and-hook vs live | Drop-and-hook saves detention time |
Dedicated program vs spot | Dedicated offers steadier, lower rates |
The rate can look strong on paper and lose money once you count the miles to reach the trailer. That is why deadhead miles are the number to watch on every power only load.
The equipment and setup you need
Power only lowers the barrier to entry because you skip the trailer, but you still need the right tractor and paperwork. The requirements are lighter, not zero.
A tractor with a standard fifth wheel that fits common trailer kingpins
Operating authority, insurance, and often trailer interchange coverage
ELD and compliance in place, same as any for-hire operation
A way to track each trailer you pull and where you dropped it
Because you are pulling equipment you do not own, clean records of hookups and drops protect you. That ties into the same discipline behind a full trucking compliance checklist.
Who power only trucking suits
Power only fits carriers who want to keep tractors productive without the capital tied up in trailers. It is a common path for growing fleets and for owner-operators managing cash.
It also helps carriers flex capacity, taking on trailer-pool work during busy stretches without buying more equipment. That flexibility is part of how carriers think about when to add the next truck versus adding utilization to what they already run.
How Datatruck keeps power only tractors profitable
Datatruck is a TMS for carriers that tracks each power only load with its deadhead, trailer, and rate attached, so you see the true profit per move, not just the quoted rate. Booking across DAT, Truckstop, and 123Loadboard feeds straight into your live cost per mile.
With trailer interchanges and drops logged in one place, nothing about the equipment you pulled gets lost. See how it keeps your tractors earning with a Datatruck demo.
FAQs
What is power only trucking?
Power only trucking is when a carrier uses its tractor to pull a trailer owned by the shipper, broker, or a trailer pool rather than its own. The carrier supplies the power unit and driver, and someone else provides the trailer.
How much do power only loads pay?
Power only loads are paid per mile or as a flat rate for the move, and pay varies with lane demand, deadhead to the trailer, and whether the work is spot or dedicated. Because you save on trailer ownership, the rate reflects that, so deadhead miles decide whether a load is profitable.
What equipment do you need for power only trucking?
You need a tractor with a standard fifth wheel, operating authority, insurance including trailer interchange coverage, and ELD compliance. You do not need to own a trailer, since the shipper, broker, or trailer pool provides it.
Is power only trucking profitable?
Power only trucking can be profitable because it lowers equipment cost and keeps tractors moving, but profit depends on controlling deadhead miles to reach the trailer. Tracking true cost per mile on each load is what separates the good loads from the money losers.
