Deadhead miles rarely show up as their own line on a P&L, but they are often the biggest hidden drag on fleet profitability. Here's why empty miles keep climbing as fleets grow, what the best carriers do differently, and a practical framework to bring your own number down.

Your dispatcher just booked a good rate on a load headed to a small town three hours off the interstate. The customer is happy, the truck is loaded, and on paper the numbers look fine. Then the truck delivers, and there is nothing else moving anywhere near that town for the next two days. The driver runs back empty, burning fuel and hours of service on miles that generate zero revenue. Multiply that scenario across every truck in the fleet, every week, and you start to see where a meaningful share of your margin actually goes.

This is not a rare event. It is a structural feature of how a lot of carriers still plan freight: one load at a time, reactively, without a clear view of what the truck should be doing on the way back. The result shows up in the numbers you already track: cost per mile creeping up, revenue per truck stuck in place, and a nagging sense that the fleet is working harder without getting more profitable.

Why Empty Miles Are the Silent Profit Killer

The Real Cost Behind a Familiar Problem

Empty miles, often called deadhead miles, are the miles a truck runs without a paying load, usually after a delivery and before the next pickup, or while repositioning between lanes. Every fleet has some deadhead. The real issue is that most carriers don't have a reliable number for how much they're actually running, and don't have a repeatable process for bringing that number down.

According to the American Transportation Research Institute's 2026 Analysis of the Operational Costs of Trucking, the average cost to operate a truck in the US reached $2.336 per mile in 2025, the highest figure in the report's history and up 3.4 percent from the year before. Excluding fuel, that cost rose 4.2 percent to $1.854 per mile. That per-mile cost, covering fuel, maintenance, tires, insurance, and driver pay, keeps accruing whether or not the trailer is full. The same report noted that deadhead mileage stayed elevated through 2025, even as carriers cut truck counts and left more equipment unseated to control costs.

Industry benchmarking generally places dry van and reefer deadhead somewhere in the 15 to 20 percent range of total miles, though the real number varies a lot by lane, region, and freight type. For a truck running 100,000 miles a year, even a conservative 15 percent deadhead rate means 15,000 miles that produced nothing but expense. At current per-mile operating costs, that is a meaningful chunk of a truck's annual budget disappearing before a fleet owner ever sees it broken out as its own line.

Why This Rarely Shows Up as a Single Line Item

Empty miles rarely appear on a P&L as "deadhead cost." Instead, they get absorbed into fuel spend, maintenance schedules that come around faster than expected, and a cost-per-mile number that looks stubbornly high even when freight rates are decent. Fleet owners often sense something is off. "Our margins keep shrinking" is one of the most common things owners say, without being able to point to a specific cause. Empty miles are frequently a large part of the answer, hiding in plain sight inside numbers everyone is already watching.

Why Deadhead Keeps Climbing as Fleets Grow

Reactive Load Booking

At smaller fleets, one experienced dispatcher often knows the regular lanes and regular customers well enough to line up a return load out of habit. That knowledge doesn't scale. As a fleet adds trucks and lanes, load booking increasingly happens load by load, under time pressure, with the dispatcher solving today's problem rather than planning the truck's next 48 hours.

No Visibility Into Where Trucks Actually Are

Without a shared, real-time view of where every truck is and where it will be tomorrow, backhaul opportunities get missed simply because nobody had the full picture at the right moment. A load that would have been a good fit gets booked to a different truck, or missed entirely, because the information lived in one dispatcher's head or in a spreadsheet nobody else was watching.

Backhaul Treated as an Afterthought

Many carriers plan the outbound load carefully and treat the return leg as something to figure out once the truck is already close to delivery. By then, the best return options are often already gone. Backhaul planning that starts after delivery is planning too late.

What the Best Carriers Do Differently

They Plan the Return Leg Before the Truck Leaves

High-performing carriers treat every load as two decisions: the load itself, and what the truck does immediately after. They start looking for backhaul options as soon as the outbound load is booked, not after it delivers, which gives dispatchers far more options to choose from.

They Build Regional Density Instead of Chasing One-Off Long Hauls

A single high-paying long haul that ends in a freight desert can cost more in deadhead than it earns in rate. Carriers with the best deadhead numbers tend to concentrate on regional lanes and customer bases dense enough that a return load is usually available, even if the individual loads pay a bit less than a one-off long haul.

They Track Actual Miles, Not Just Billed Miles

It's common for the miles a driver actually runs to differ from the miles that were planned or invoiced, sometimes because of detours, sometimes because of how a route was estimated in the first place. Carriers that only look at billed mileage are working from an incomplete picture of what deadhead is really costing them.

A Practical Framework for Cutting Empty Miles

Step 1: Measure Your Real Deadhead Percentage

You can't manage what you don't measure. Pull actual GPS-tracked mileage, not planned mileage, for every truck over a full month, and calculate empty miles as a percentage of total miles. Do this by lane, not just fleet-wide. A fleet-wide average can hide lanes running at 5 percent deadhead and others running at 40 percent.

Step 2: Set a Target by Lane, Not Fleet-Wide

Once you know your real numbers, set realistic targets per lane or per region rather than one blanket company target. A dense regional lane might realistically get to single digits. A long, thin lane into a low-freight area might never get below 25 percent, and that's useful information for pricing decisions, not just an operational failure to fix.

Step 3: Make Backhaul Part of the Dispatch Workflow

Backhaul search should be a required step at the moment a load is booked, not an optional task a dispatcher gets to if there's time. Building it into the standard workflow, with visibility into upcoming truck availability across the whole fleet, is what turns backhaul planning from an occasional win into a consistent habit.

Where Technology Actually Helps

Route Optimization That Flags Empty Legs Before They Happen

Modern planning tools can surface upcoming empty legs as soon as a load is assigned, showing dispatchers nearby freight or suggesting a route adjustment before the truck is already running empty. That shifts backhaul planning from something a dispatcher has to remember to something the system actively prompts.

Real Mileage Tracking That Catches the Gap Between Planned and Actual

Comparing GPS-tracked actual mileage against planned or invoiced mileage exposes the gap between what a route was supposed to cost and what it really cost, lane by lane. That gap is often where a fleet owner finds the clearest, most actionable case for changing how a specific lane or customer is priced or planned.

How Dashdoc Fits Naturally

Dashdoc's planning board and route optimization tools give dispatchers a live view of every truck's location and upcoming availability, so backhaul opportunities can be flagged and matched to open capacity before a truck ever runs empty, rather than after the fact. Real mileage tracking compares actual GPS mileage to planned mileage on every load, surfacing the lanes and customers where the gap between what was priced and what was actually driven is eating into margin. Combined with profitability reporting that breaks performance down by lane and by customer, fleet owners get the visibility to see, in one place, exactly where empty miles are concentrated and which changes would move the needle most.

None of this replaces a dispatcher's judgment. It gives that judgment better information to work with, so backhaul planning stops depending on memory and starts running as a standard part of how every load gets planned.

Frequently Asked Questions

What is a good deadhead percentage for a trucking company?

There's no single right number, since it depends heavily on lane density and freight type. Dense regional lanes can realistically run in the single digits, while long or thin lanes into low-freight areas may run considerably higher. The more useful benchmark is your own number by lane, tracked consistently, so you can see whether it's improving or drifting the wrong way.

How do I calculate my fleet's empty miles?

Divide total miles run without a paying load by total miles run, using actual GPS-tracked mileage rather than planned or invoiced mileage. Calculate it by lane and by truck, not just as one fleet-wide average, since a single blended number can hide big differences between your best and worst lanes.

Can route optimization software really reduce empty miles?

It helps most when it surfaces backhaul opportunities at the moment a load is booked, while there's still time to act, rather than after the truck is already running empty. The software itself doesn't eliminate deadhead. It gives dispatchers better visibility to make the backhaul call earlier and more consistently.

Is it worth taking a lower-paying backhaul just to avoid running empty?

Often yes, once you account for the real cost of the empty miles you'd otherwise run. A backhaul at a modest rate usually beats deadheading for free, but the right comparison is the backhaul rate against your actual cost per empty mile, not against the rate you'd want in an ideal world.

How does Dashdoc help carriers reduce empty miles?

Dashdoc combines a live planning board, route optimization, and real mileage tracking so dispatchers can see backhaul opportunities as soon as a load is booked and compare actual mileage to planned mileage lane by lane. That combination turns backhaul planning into a standard step in the dispatch workflow instead of something that depends on one person remembering to check.
