Every mile your truck runs empty on the way home burns fuel and driver hours while earning nothing. Backhaul in trucking is the fix, a paid return load that covers the trip back. Roughly 35% of heavy-duty vehicles on U.S. roads run empty at any moment, a lot of return-trip revenue on the table.

What Is Backhaul in Trucking

Backhaul in trucking is the freight a carrier hauls on the return trip, from point B back toward point A, after delivering the outbound load. It keeps the truck from running home empty.

The outbound leg is the headhaul, usually your best-paying freight. The backhaul is whatever revenue you add on the way back. Internal backhaul is a private fleet moving its own freight both ways. External backhaul is a return load booked from a different shipper or broker, the common case for owner-operators.

Backhaul vs Headhaul vs Deadhead

These three terms describe every mile your truck runs. Getting them straight is the first step to pricing a roundtrip.

Deadheading burns fuel and driver time but earns nothing. Our guide to what deadhead miles cost carriers breaks down the gap a backhaul closes.

Why Backhaul in Trucking Matters for Revenue Per Mile

A backhaul spreads your fixed costs across more paid miles, lifting revenue per mile on the roundtrip. Companies can lower transportation costs by an estimated 9% to 15% by capturing return loads instead of running empty.

Say your all-in cost is $1.80 per mile, you run a 500-mile headhaul at $2.50, then face a 500-mile trip home.

The backhaul pays only $1.20 per mile on its own, under your cost floor, yet it lifts the roundtrip from $1.25 to $1.85 per mile. That is why a cheap return beats deadhead. Model it with your cost per mile and revenue per mile.

What Makes a Good Backhaul Load

Not every return load is worth taking. Judge it on more than rate.

• Rate per mile against deadhead-to-pickup. A high rate 120 miles out of route can net less than a lower rate at the dock.

• Broker payment history. A good rate from a slow-paying broker ties up cash you need for fuel.

• Delivery window fit. The load must fit your Hours of Service limits.

• Destination market strength. Do not haul into a weak-outbound market where your next load pays little.

That last point is the one most drivers miss. DAT's dry-van study found Billings, Montana was the least balanced backhaul market at 2.19 loads in for every one out, so deliver there and you are stuck. Los Angeles, the least balanced headhaul market at 1.42 outbound loads per inbound, is a place freight leaves easily.

How to Find and Price a Backhaul in Trucking

Backhaul planning starts before or during the outbound haul, not after you deliver, because the best return loads book first.

1. Book the outbound only after you know the destination has return freight.

2. Search return loads while still rolling on the headhaul, not at the dock.

3. Anchor your ask to the market rate, then set a walk-away at your cost per mile.

4. Take the load if the roundtrip RPM clears your cost, even when the rate looks low.

Backhaul rates run lower than headhaul because a backhaul market has more carrier capacity than shipper demand. Your only edge is your walk-away number. If the rate drops below what keeps the roundtrip above your cost floor, deadheading to a stronger headhaul market beats freight that loses money. Searching across DAT, Truckstop, and 123Loadboard at once surfaces more options.

Challenges of Backhauling

A roundtrip with a return load is two loads and two transactions. Three things trip carriers up.

• Hours of Service. The return load has to fit inside remaining drive time or it is not an option.

• Trailer compatibility. Reefer and food-grade freight carry contamination rules that block many return loads.

• Two transactions. Two rate cons, two invoices, two settlements, twice the paperwork by hand.

Where Datatruck Fits

A driver refreshing a load board by hand judges one return load at a time. Datatruck is a TMS for carriers that surfaces profitable return loads automatically, matching remaining Hours of Service, deadhead-to-pickup radius, destination market strength, and broker credit so the roundtrip math is done before you commit. Because it is AI-native, the AI Dispatcher searches every major loadboard and streams matches as they appear, so you book backhauls that clear your cost per mile.

FAQs

What is the difference between backhaul, headhaul, and deadhead?

Headhaul is the outbound higher-paying load, backhaul is the paid return home, and deadhead is running empty with no revenue. A backhaul turns a deadhead leg into paid miles.

Why do backhaul loads pay less than headhaul loads?

Backhaul rates run lower because backhaul markets have more carrier capacity than shipper demand, which hands shippers the pricing power. Carriers accept the lower rate rather than deadhead out empty and lose the return leg.

How do I know if a backhaul rate is worth taking?

A backhaul is worth taking whenever it lifts your roundtrip revenue per mile above your all-in cost per mile, even if the rate alone looks low. Factor in deadhead-to-pickup distance, broker payment history, and destination market strength.

How can I find a backhaul load before I finish my delivery?

Start searching return loads while still rolling on the outbound haul, since the best return freight books fastest. A TMS that matches loads to your Hours of Service and deadhead radius surfaces the profitable options automatically.
