Every mile a truck travels costs money, but not every mile earns revenue. Deadhead miles, when a truck travels without freight, are one of the biggest challenges in trucking. They increase fuel costs, driver expenses, and equipment wear while reducing profitability.
This guide explains what deadhead miles are, why they matter, and how freight route optimization helps carriers reduce empty runs and improve trucking efficiency.
Key Takeaways
- Deadhead miles are miles driven without carrying a paying load.
- ATRI’s latest data shows empty miles averaged 16.7% of truck miles.
- 20,000 empty miles can cost carriers about $37,000 each year.
- Freight route optimization helps reduce costly empty truck runs.
- Fewer deadhead miles mean lower costs and more reliable deliveries.
What Are Deadhead Miles?
Deadhead miles, also called empty miles, refer to the distance a commercial truck travels without transporting freight.
This typically happens after a delivery when a truck must travel to another pickup location without a load or return to its operating area empty.
For example:
- A driver delivers a load in Fresno, and the next available pickup is 90 miles away in Stockton. Those 90 miles are deadhead.
- A truck completes a delivery and returns to its home terminal in Bakersfield without a return load.
- A truck repositions to a busier freight market because its delivery destination has little outbound volume.
Although the truck is moving, it isn’t generating revenue during that portion of the trip.
Deadhead vs. Bobtail: Not the Same Thing
The two terms get mixed up constantly, and the difference matters for both cost and safety:
- Deadhead: the tractor is pulling a trailer, but the trailer is empty.
- Bobtail: the tractor is driving with no trailer attached at all.
What Empty Miles Actually Cost
Here’s the number that should get every fleet manager’s attention: according to ATRI’s Analysis of the Operational Costs of Trucking: 2025 Update, empty miles rose to an average of 16.7% of total miles in 2024. Some industry estimates run higher, up to 35% for owner-operators and specialized equipment, translating to tens of billions of unproductive miles across the US every year.
Why does this hit so hard? Because a deadhead mile isn’t a neutral mile. Every operating cost still applies:
| Cost that keeps running | Applies on empty miles? |
| Fuel | Yes |
| Driver wages and hours of service | Yes |
| Maintenance and tire wear | Yes |
| Insurance and depreciation | Yes |
| Revenue earned | No |
At an all-in operating cost near $1.85 per mile, a single truck running 20,000 empty miles per year absorbs roughly $37,000 in pure expense with nothing to show for it. Multiply that across a fleet and deadhead quietly becomes the largest controllable drag on profitability most carriers never measure.
Well-run truckload carriers typically target a deadhead rate between 15% and 22%. Fleets running above 28% have the most room for fast improvement, and fleets with disciplined route optimization can get into single digits on established lanes.
How to Calculate Your Deadhead Percentage
The formula is simple:
Deadhead % = (Empty Miles ÷ Total Miles) × 100
What Causes Deadhead Miles?
While some empty miles are unavoidable, several operational factors can increase them.
- Limited Backhaul Opportunities: A carrier may find a paying load for the outbound trip but struggle to secure freight for the return journey.
- Poor Route Planning: Without careful scheduling, trucks may travel long distances between deliveries and pickup locations.
- Regional Freight Imbalances: Some markets generate significantly more outbound freight than inbound freight, creating unavoidable empty repositioning.
- Last-Minute Shipment Changes: Cancellations, delays, or customer schedule changes can leave trucks without an immediate replacement load.
- Seasonal Demand Fluctuations: Peak harvest seasons, holiday shipping, or changing consumer demand can temporarily create capacity imbalances in certain regions.
How Smart Freight Route Optimization Reduces Empty Runs
Cutting deadhead isn’t about one tool, it’s a planning discipline supported by technology. These are the strategies that separate efficient carriers from the rest:
1. Plan the Backhaul Before the Outbound
The single biggest shift: search for the return load the moment an outbound load is confirmed, not after the driver calls in empty. By then, every other carrier in that market is chasing the same freight. Round-trip thinking turns one-way hauls into profitable loops.
2. Triangulate Routes
Instead of A-to-B-and-back, efficient carriers build A → B → C → A patterns, chaining loads so the truck is earning on every leg. On repeatable lanes, this becomes a standing route rather than a weekly scramble.
3. Build Consistent Two-Way Lanes
Carriers who run the same corridors repeatedly learn which destination markets produce weak return freight, and build direct relationships with shippers near those delivery points. Direct shipper relationships consistently beat spot-market load boards on both rate and reliability.
4. Use Load Matching and Real-Time Visibility
Modern freight route optimization combines load matching, GPS tracking, predictive analytics, and AI-powered routing to reduce empty miles. These tools help dispatchers find nearby loads faster, plan efficient routes, and keep trucks moving with paying freight. As a result, many fleets have reduced deadhead miles from 16-20% to around 8-12% by adopting smarter, data-driven planning.
We’ve covered these tools in more depth in our guide on how technology is helping trucking companies work smarter.
5. Track Deadhead Like You Track Revenue
The fleets that protect margin best treat deadhead percentage with the same weight as revenue per mile, reviewed by truck, by driver, and by lane, every month. What gets measured gets managed.
How Roadies Inc Keeps Trucks Loaded, and Why It Matters to You
At Roadies Inc, minimizing empty miles is built into every dispatch out of Bakersfield. Our Central Valley location, on the corridor linking Southern California’s ports to Northern California, gives us natural two-way freight flow that many carriers have to fight for.
Real-time asset tracking through our logistics systems lets dispatch line up the next load before delivery is complete, our freight brokerage network opens return freight beyond any single load board, and cross-docking in Bakersfield consolidates shipments to cut the repositioning that creates empty runs in the first place.
A Quick Note on Deadhead and Safety
One detail that rarely makes it into cost discussions: an empty trailer can weigh roughly half of what a loaded one does, which changes how a truck handles in wind, rain, and ice. High-profile empty trailers are especially vulnerable to crosswinds. Professional carriers train drivers specifically for empty-trailer handling, another reason experienced operations matter on every mile, loaded or not.
Frequently Asked Questions
What are deadhead miles in trucking?
Deadhead miles are the distance a truck travels without carrying freight, typically between a delivery and the next pickup location.
Why are deadhead miles a problem?
Empty miles increase fuel costs, driver expenses, maintenance costs, and equipment wear while generating no revenue.
How do carriers reduce deadhead miles?
Carriers reduce empty runs through freight route optimization, backhaul planning, freight brokerage networks, transportation management systems, and real-time dispatching.
What is freight route optimization?
Freight route optimization is the process of planning routes, schedules, and load assignments to improve efficiency, reduce transportation costs, and maximize fleet utilization.
How does freight route optimization benefit shippers?
It can improve capacity availability, support on-time deliveries, enhance shipment visibility, and contribute to more efficient transportation operations.
