Backhaul Freight Explained: Cutting Empty Miles and Cost

There is a number in trucking that should keep every logistics manager up at night: a large share of trailer miles are run completely empty. The industry calls it deadhead, and it is exactly what it sounds like, a truck rolling down the interstate hauling nothing but air, burning diesel to reposition for its next paying load.

That empty trailer is not just the carrier's problem. It is a standing invitation. Every deadhead mile is capacity already paid for, already fueled, already moving in a direction, and it is going to waste. If your surplus Gaylords happen to sit along that route, you have a chance to turn someone's empty return trip into your cheapest freight of the year.

That is backhaul, and it is one of the most underused levers in bulk logistics. It cuts your cost, cuts road carbon, and keeps reusable boxes moving into a second life instead of into a dumpster. Let us break down how it works and then run the actual numbers on a 500-mile lane.

Deadhead vs. Backhaul: Know the Difference

Start with the vocabulary, because the two terms get muddled. Deadhead is the failure state, a truck running empty with no revenue on board. Backhaul is the fix, loading freight onto that otherwise-empty return leg so the trailer earns on the way back instead of just repositioning.

A typical freight movement has a headhaul, the primary loaded trip a shipper pays full rate for, and then a return. If nothing fills the return, it deadheads. Backhaul freight slots into that return at a steep discount because the carrier has already committed the trip. You are not paying to move a truck, you are paying to fill space that was moving anyway.

• Headhaul: the primary loaded trip, priced at full market rate.
• Deadhead: the empty return, pure cost and carbon with no offsetting revenue.
• Backhaul: freight loaded onto that return leg at a discounted rate.

Why the Box Business Is Built for This

Bulk box logistics is almost perfectly shaped for backhaul, and here is why. Trucks are constantly delivering pallets, product, and new packaging into warehouses across the country. Those same trucks then need to get back to their origin region. Meanwhile, those same warehouses are sitting on stacks of surplus Gaylords they want gone.

Match the two and the loop closes itself. A truck that delivered a load to your dock can leave carrying your folded-flat surplus bins on its return, rather than deadheading home. Because Gaylords fold flat, a single trailer swallows an enormous count of them, so the density is excellent and the effective per-unit freight cost drops through the floor.

The greenest, cheapest mile a truck ever drives is the empty one you fill. Backhaul does not add a trip to the road, it deletes the waste from a trip already happening.

A Worked 500-Mile Example

Numbers make it real, so let us build a realistic lane. Say a carrier delivers goods to a distribution center 500 miles from its home base near our Woods Cross, Utah hub. Normally that truck deadheads the 500 miles home. You have a trailer's worth of surplus double-wall Gaylords the DC wants cleared.

A dedicated one-way haul for that freight might be priced around full market rate, call it roughly 2.50 dollars per mile, or about 1,250 dollars to move an empty-return trailer's worth of boxes as its own trip. As a backhaul on the already-committed return leg, the carrier only needs to beat the cost of running empty, so the rate might fall to somewhere near 1.20 to 1.50 dollars per mile, roughly 600 to 750 dollars for the same 500 miles.

• Dedicated one-way move: about 1,250 dollars for the 500-mile lane.
• Same load as backhaul: roughly 600 to 750 dollars, because the trip already exists.
• Net freight savings: on the order of 40 to 55 percent on that lane.
• Carbon: the diesel for those 500 miles burns whether the trailer is full or empty, so filling it drives the emissions per box toward zero.

The carbon math is the part people underrate. That truck was going to drive 500 miles regardless. The fuel is burned either way. By loading your boxes onto the empty return, the marginal emissions of moving them are close to nothing, and you have avoided commissioning a separate truck that would have added its own 500 miles of diesel to the atmosphere.

When Backhaul Actually Works

Backhaul is powerful but it is not magic, and it does not fit every situation. It thrives on flexibility and predictable lanes, and it struggles when your timing is rigid or your freight is time-critical. Knowing the conditions keeps you from chasing a discount that will not materialize.

The sweet spot is non-urgent, foldable, high-density freight, exactly what surplus Gaylords are, moving along a lane where empty trucks already run. If you can stage your surplus and wait a few days for the right truck, you unlock the best rates. If you need it gone tomorrow at a fixed hour, you are back to paying for a dedicated move.

• Works well: flexible pickup windows, predictable lanes, foldable high-density loads.
• Works well: recurring surplus you can stage and batch for the right truck.
• Struggles: tight appointment times, urgent one-off pickups, oddball routes with no return traffic.

Setting Your Warehouse Up to Capture It

Capturing backhaul value takes a little front-end discipline, but the payoff compounds. The core move is to make your surplus truck-ready before the truck arrives, so a driver can load and roll without eating expensive dock time. Loose, un-flattened, damp boxes kill the economics fast.

Keep surplus bins folded flat, banded, and staged near an accessible dock. Track your recurring inbound lanes so you know which carriers routinely deadhead home past your building. Then coordinate pickups against that traffic. We buy, sell, recycle, and haul used and new Gaylords across the US, and matching pickups to existing freight lanes is exactly how we keep the boxes and the cost both moving in your favor.

The Bottom Line on Empty Miles

Empty trailer miles are a waste that somebody is already paying for, in dollars and in carbon. Backhaul freight lets you split that waste in your favor, buying cheap capacity that was going to move anyway while keeping reusable boxes cycling into their next job. On a 500-mile lane the savings can run 40 to 55 percent, and the marginal emissions of your load approach zero.

The warehouses that win at this are not the ones with the most trucks, they are the ones paying attention to where empty trucks already go. Stage your surplus, learn your lanes, and fill the deadhead. Since 2014 we have built our hauling around exactly that principle, because the cheapest, cleanest freight on earth is the empty mile you managed to fill.
