Power only dispatch services built on hooks, not dock doors

Power only is the purest version of what this desk is for. You bring the tractor, a shipper or broker brings the trailer, and the best power only weeks are the ones where you almost never sit at a dock. A preloaded trailer at 05:00, a drop at a distribution center, a reload already waiting in the next yard. Every hook that replaces a live load gives hours back to your 14-hour window. Our dispatchers build weeks around those hooks, and every load still reaches you as a rate confirmation for your yes or no.

BOARD 02A HYPOTHETICAL WEEK

A hypothetical power only week, day by day

Meet Driver A, a solo owner-operator with a day cab and no trailer. Driver A doesn't exist; this week is a hypothetical built to show how preloaded trailers change the clock, not a record of real results. Tap any day to open its log. Notice how short the amber on-duty blocks are when the work is a hook instead of a live load, and notice Wednesday, which is the day the plan breaks.

The plan breaks: the preloaded trailer wasn't ready and the yard held Driver A for 2 hours. Detention gets claimed, the afternoon leg is shortened, and Thursday's hook moves later so the 10-hour break stays whole.

Hypothetical week for illustration; not a real driver or real results. Limits per 49 CFR 395.3.

Wednesday is in there on purpose. Power only plans break, and they break in predictable ways: a trailer that isn't loaded when the yard said it would be, a yard jockey who's two trucks behind, a seal number that doesn't match the paperwork. A dispatcher can't prevent those. What a dispatcher can do is see them coming, claim the detention, and move the next hook before your 10-hour break gets squeezed.

BOARD 03HOW POWER ONLY WORKS

How power only actually works

  1. 1Yard or shippertrailer staged
  2. 2Inspect & hookseal, lights, paperwork
  3. 3Drive the loadinside your 11 and 14
  4. 4Drop & hook againreload already waiting

In power only, the trailer belongs to someone else: a shipper, a broker with a trailer pool, or another carrier. You provide the tractor and the driver. Loads usually run in one of three ways. Drop and hook, where you drop a loaded trailer at the receiver and hook an empty or a preloaded one. Pool programs, where a broker or shipper keeps trailers staged at yards and assigns you loads out of them. And one-off moves, where you pick up a loaded trailer, deliver it, and leave it.

Programs vary a lot. Some large brokers and shippers run structured power only programs with their own onboarding, insurance requirements, trailer inspection rules and app-based load assignment. Others are informal. Rates, requirements and rules change, so check each program's current terms before you count on it, and read the trailer interchange agreement before you sign it. We help you sort which programs fit your base and your hours, and we handle the setup paperwork.

Yard work deserves a note. Moving a trailer around inside a yard can be recorded on your ELD as a yard move, which counts as on duty not driving, but only when the movement really is within the yard or terminal. Yard moves aren't a way to hide driving on public roads, and we never plan as if they were. Yard moves on an ELD, explained

BOARD 04HOOKS VS DOCKS

Why hooks beat docks on the clock

The 14-hour window under 49 CFR 395.3(a)(2) runs from when you come on duty, and it doesn't stop while a dock crew unloads your trailer. A live unload that takes three hours costs three hours of window. A drop and hook usually takes a fraction of that: inspect, hook, check the lights and the seal, sign, roll. On a two-stop day that difference can be the gap between a reload today and a reload tomorrow.

That's the whole economic case for power only, and it's why our planning starts with the yards, not the rate. A slightly lower-paying load with a preloaded trailer waiting can beat a higher rate with a live unload, once you count the hours. We show you both sides of that math on the rate con conversation before you decide.

Power only rates also come with their own fine print. Some programs pay a flat amount per move, some pay per mile, some add a fee when the trailer isn't ready on time, and some don't. Before you see a power only load, we confirm how it pays, whether there's a trailer-not-ready or detention clause, and how the program handles a trailer you have to reject at the yard. Those details matter more in power only than anywhere else, because the trailer is the one thing you don't control.

BOARD 05WHAT THE DESK HANDLES

What a power only dispatcher handles

Finds the programs that fit your base

Trailer pools are local. A great program 300 miles from your house is a deadhead problem. We look for yards and drop lots inside your normal running area first.

Confirms the trailer before you roll

Is it loaded, sealed and released? Which door or row? We confirm with the yard or broker before you leave, because the most common power only failure is a trailer that isn't ready.

Plans hooks into your clock

Each hook, inspection and drop is a short on-duty block. We place them so your 30-minute break happens at a swap, not as an extra stop.

Claims yard delays

When a yard holds you, we document the times and claim detention under the program's terms, the same way we would at a dock.

Keeps the reloads coming

The best power only weeks chain hooks together. We book the next trailer while you're pulling the current one.

Protect yourself on someone else's trailer

When you hook a trailer you've never seen, you inherit its condition. A careful pre-trip on every hook is your first protection: tires, lights, brakes, mud flaps, the landing gear, the doors and the seal. Note any damage on the paperwork before you leave the yard, and take photos. If a trailer has a defect that makes it unsafe, it doesn't leave the yard with you.

Then read the trailer interchange agreement for each program. It spells out who pays for what if the trailer is damaged in your care, and what insurance you're expected to carry. We'll help you compare programs, but the agreement is a contract between you and the trailer owner, so read it yourself before you sign.

Your ELD will also show the moves other drivers made with a shared tractor or in a shared yard as unassigned driving events if your device picks them up. Review and annotate them when they appear; a fleet's unassigned events are a common audit question, and they're easier to explain the same day than six months later.

WHO IT FITS

Power only fits owner-operators and small fleets who want to drive more and wait less, who live near active drop yards or trailer pools, and who don't want the cost and upkeep of their own trailers. If your area has few power only programs, a dry van or reefer of your own may earn more, and we'll tell you that honestly on the setup call. Either way, every load still reaches you as a rate confirmation first, and the decision is yours.

BOARD 06BEFORE THE FIRST HOOK

What you need before your first power only load

Your own authority

Power only is usually booked on your MC. Some programs take new authorities; others want months of history.

Trailer interchange coverage

Brokers and programs commonly ask for insurance that covers damage to a trailer you don't own. Check the limit each program requires.

The right tractor setup

Fifth wheel in good shape, gladhands and light cord that work, and a tractor that matches the trailers in the program.

A clean pre-trip habit

You'll be inspecting trailers you've never seen. A careful pre-trip on every hook protects you from inheriting someone else's defect.

An ELD you know well

Yard moves, duty status changes at every hook, and unassigned events from other drivers' moves all show up. Knowing your device saves headaches.

Running your own trailer too? Dry van dispatch works the same way, with the same fee.

BOARD 07FEE & FAQ

What power only dispatch costs

The fee is the same for every truck we dispatch: 5% of gross for one tractor with authority older than 6 months, 7% while your MC is under 6 months, and 4% for fleets of 2 or more trucks while the fleet rate lasts. No setup fee, no minimums, month to month, and nothing on a week you don't haul. Full pricing

You provide the tractor and driver; the trailer comes from a shipper, broker or trailer pool. Your dispatcher finds power only loads and programs that fit your base and hours, negotiates the rate, sets up the paperwork and plans hooks so you spend less time at docks. Every load reaches you as a rate con to confirm.
