Equipment / Trailer arrangements
Power Only in trucking
Plain-English explanation
Power only means the carrier supplies the tractor and driver but hauls a trailer supplied by someone else. The trailer may belong to a shipper, broker, private fleet, leasing company, or another carrier arrangement.
Equipment terms are best read physically: what is on the tractor, what trailer is assigned, how the freight loads, and what the driver can inspect before rolling.
Why it matters in trucking
Power-only work changes trailer responsibility. The driver still needs to inspect the trailer, confirm trailer number and condition, check paperwork, and understand where the trailer must be dropped or returned.
The right equipment term helps prevent the wrong truck from being sent to pickup, especially for reefer, flatbed, liftgate, power-only, or drop-trailer work.
Example in real use
A carrier sends a tractor to a retail distribution center, hooks to a preloaded customer trailer, checks lights and tires, records the trailer number, and delivers it to the store network.
Common mistakes or confusion
- Assuming the supplied trailer is road-ready without a pre-trip inspection.
- Missing trailer return, interchange, seal, or damage-reporting instructions.
- Confusing power only with drop trailer; one describes who supplies power, the other describes a trailer-handling method.
