Deadhead Miles
What deadhead miles cost in fuel, HOS, and profitability, and why empty moves still need a real trip plan.
By Dale Connors, Founding Editor · Content reviewed quarterly against FMCSA guidance and official state resources. Definition
Deadhead miles are miles driven in a commercial truck without a revenue-producing load — typically when a driver repositions an empty trailer from a delivery point to a new pickup location. The term refers to the empty tractor-trailer combination moving without cargo.
Deadhead is an unavoidable part of trucking operations for most drivers and carriers. The goal is to minimize it relative to loaded miles, because every deadhead mile consumes fuel, HOS, tires, and maintenance without generating revenue. The ratio of loaded miles to total miles (loaded + deadhead) is a key efficiency metric for owner-operators and carriers.
In a trip planning conversation
Deadhead miles require the same planning attention as loaded miles. The driver still needs fuel and a fuel plan, still consumes HOS, and still needs to identify overnight parking. An owner-operator who accepts a load because the loaded rate looks good but has not counted the deadhead to the pickup location may find the load is not profitable when total cost is calculated.
Dispatchers should include deadhead miles in the HOS calculation when positioning a driver for a new load. A driver who has 9 hours of available driving time and is 8 hours of driving from the pickup location needs an overnight stop in the deadhead segment — the HOS clock does not pause because the truck is running empty.
What deadhead does to the effective rate
| Scenario | Loaded miles | Deadhead miles | Load revenue | Effective $/mile |
|---|---|---|---|---|
| Clean load, no repositioning | 500 | 0 | $1,250 | $2.50 |
| Short deadhead — nearby pickup | 500 | 75 | $1,250 | $2.17 |
| Moderate deadhead — one market over | 500 | 150 | $1,250 | $1.92 |
| Long deadhead — repositioning to next region | 500 | 300 | $1,250 | $1.56 |
Why it matters in load evaluation
For owner-operators, deadhead affects profitability directly. The cost-per-mile calculation for any load should include the deadhead to pickup, not just the loaded portion. A load that looks like $2.50/mile on a rate confirmation may be $1.56/mile after the repositioning miles are counted.
Weather and route planning for deadhead should get the same attention as loaded segments. An empty trailer in high wind is actually more vulnerable than a loaded one — lighter trailers are more susceptible to lateral forces. Deadhead miles still consume HOS, fuel, and tires.
What to check before relying on this
Include deadhead miles in total cost analysis before accepting a load. Plan fuel, HOS, and parking for the deadhead segment the same as for the loaded segment. Account for weather risk on deadhead segments — empty trailers have different handling characteristics than loaded ones.

What is a deadhead in trucking?
Deadhead refers to driving a commercial truck without a paying load — usually when repositioning an empty trailer from a delivery destination to the next pickup location. Deadhead miles do not generate revenue but still consume fuel, driver hours, equipment wear, and operating costs. For owner-operators, the number of deadhead miles directly affects profitability per total mile driven.
How does deadhead affect an owner-operator's per-mile rate?
Deadhead miles reduce the effective revenue per mile for a load. If a load pays $2.00/mile for 500 loaded miles, that is $1,000. If reaching the pickup required 200 miles of unpaid deadhead, the actual revenue over 700 total miles is $1,000 ÷ 700 miles = $1.43/mile effective rate. Owner-operators should calculate rate per total mile — loaded plus deadhead — rather than rate per loaded mile only, to accurately evaluate load profitability.
