Backhaul
Backhaul is the return leg of a truck trip after the primary load has been delivered. A driver who hauls freight from Dallas to Atlanta needs to get back to Dallas, and running that return trip empty means the carrier absorbs fuel, driver time, and equipment cost with zero revenue. Backhaul freight fills that return trip, turning a cost center into a revenue opportunity for the carrier and a discount opportunity for the shipper.
Why it matters
Empty miles are the single largest source of waste in trucking. Industry data shows that roughly 35 percent of truck miles in the US are driven empty, costing carriers an estimated $50 billion annually. For shippers, backhaul freight is often priced 15 to 30 percent below headhaul rates because carriers prefer discounted revenue to zero revenue. Understanding backhaul dynamics helps freight teams negotiate better rates on lanes where carriers need return volume.
When to use it
Look for backhaul opportunities when your shipping lanes run in the opposite direction of dominant freight flows. For example, freight moving from the Southeast back to the Midwest often benefits from backhaul pricing because the headhaul flow runs Midwest to Southeast. If your carrier quotes seem high on a lane, ask whether the return direction has stronger demand, and consider adjusting pickup timing to align with carrier repositioning needs.
How Warp thinks about it
Warp reduces empty backhaul miles structurally through network density. With 20,000+ carrier partners and consistent freight volume across 50+ markets, Warp matches return trips with available freight automatically. Carriers on the Warp network get consistent volume in both directions, which means they can offer lower rates without sacrificing utilization. The density effect compounds as the network grows.
