Quick answer: Deadhead miles are the miles a truck drives empty — with no paying load on board — usually to get from where the last load delivered to where the next one picks up. They're sometimes called empty miles or bobtail miles (though bobtailing specifically means running with no trailer at all). Some deadhead is unavoidable, but every empty mile burns fuel and wears the truck without earning a dollar, so keeping the percentage low is one of the clearest levers a carrier has on profitability.
Key takeaways
- Deadhead = empty, non-revenue miles, most often between a delivery and the next pickup.
- Empty miles cost real money — fuel, maintenance, and wear — while your fixed costs keep accruing the whole time.
- You can't hit zero, but tracking the deadhead percentage per truck and dispatching around it can move the number meaningfully.
Why deadhead miles happen
A truck can't always deliver a load and pick up the next one at the same dock. When a load drops in a low-freight area, or the next good-paying load is 90 miles away, the truck has to run empty to reach it. That's deadhead. Common causes:
- Delivering into a region with little outbound freight
- Repositioning to a better freight market or a home base
- A pickup that's simply not near the last drop
- Cancelled or fallen-through loads that leave a truck stranded
Some of this is the nature of the job. The goal isn't to eliminate deadhead — it's to stop treating it as invisible.
What deadhead actually costs
The mistake carriers make is thinking an empty mile is "free" because there's no load to worry about. It isn't. On a deadhead mile you still pay for:
- Fuel — the same burn rate as a loaded mile, minus a little for weight
- Maintenance and tire wear — accruing per mile regardless of cargo
- Driver time — and mileage pay, if the driver is paid for empty miles
And here's the part that hurts most: your fixed costs don't pause. The truck payment, insurance, and permits are being spent whether the truck is loaded or empty. So every deadhead mile spreads those fixed costs over fewer paid miles, which quietly raises your real cost per mile on the loads that do pay. A fleet running 25% deadhead has a very different cost structure than one running 8%, even with identical trucks.
How to measure deadhead percentage
You can't manage what you don't measure. Deadhead percentage is simply:
Deadhead % = empty miles ÷ total miles
If a truck runs 10,000 total miles in a month and 1,500 of them are empty, that's 15% deadhead. Track it per truck and per lane, not as a single fleet average — the average hides the trucks and regions doing the damage. A truck stuck repeatedly repositioning out of a weak market will show up immediately once you're watching the number.
Practical ways to cut deadhead miles
You won't reach zero, but these moves reliably lower the number:
- Plan the next load before the current one delivers. The biggest source of deadhead is reactive dispatch — finding the next load only after the truck is already empty. Line up outbound freight while the truck is still rolling.
- Know your weak drop regions. If certain delivery areas consistently strand trucks, factor the repositioning cost into whether you accept loads headed there in the first place.
- Use backhauls and lane pairing. Build round trips where the return leg is loaded, even at a lower rate, rather than running back empty.
- Price deadhead into the rate. If a load requires a long empty repositioning move, that cost is real — account for it when you decide whether the rate works.
- Watch the trend, not just the week. A truck creeping from 10% to 18% deadhead over a quarter is telling you something about its lanes or its utilization.
Where dispatch and the numbers meet
Cutting deadhead is really two jobs working together: dispatching so trucks stay loaded, and measuring so you can see where they aren't. When both live in one system, the loop closes — you assign the next load without fifteen browser tabs, and the empty vs. loaded miles are captured automatically instead of tallied by hand.
That's the idea behind Yolda's dispatch software: every load, truck, and driver status in one place so the next load is planned before the current one delivers. And because those loaded and empty miles flow straight into per-truck reporting and driver settlements, deadhead stops being a vague feeling and becomes a number you can actually manage.
The bottom line
Deadhead miles are the empty miles between the money — unavoidable in part, but far more controllable than most carriers assume. Measure the percentage per truck, plan loads ahead instead of reacting to an empty truck, and price long repositioning moves into your decisions. Trim a few points off your deadhead and it drops almost entirely to the bottom line, because you're earning more paid miles from the same fixed costs you were already paying.
