Accepted Truckload Volume May Be the Cleaner Freight Demand Signal Shippers Need

Truckload demand is easy to discuss and surprisingly hard to measure.

A shipper may see tender volume rising and assume the market is strengthening. A broker may see rejections falling and assume capacity is loose. A procurement team may see spot rates climbing and assume demand is recovering. All three can be directionally right and still miss the real question: how much freight actually cleared the tender process and moved?

That is why the new accepted-volume lens matters. FreightWaves reported that SONAR launched its Accepted SONAR Truckload Volume Index, a dataset designed to isolate accepted truckload demand by stripping out rejection activity. The index is available at national, regional, and market levels, updates daily, and covers total accepted volume, van, and reefer with week-over-week, month-over-month, and year-over-year change metrics.

For shippers, the important word is not "index." It is "accepted."

Tendered freight is freight offered to a carrier. Accepted freight is freight the market actually absorbed through the routing guide. That difference becomes critical when carriers are selectively accepting tenders, primary carriers are protecting margins, brokers are repricing lanes, or a shipper's routing guide is technically active but operationally unreliable.

Tender Volume Can Overstate Operational Reality

Tender data has value. It shows what shippers are asking the market to cover. But tender volume can exaggerate demand when the same shipment bounces through multiple carriers, backup options, and brokerage channels before finding capacity. One load can create multiple signals if the routing guide is unstable.

That matters in soft markets as much as tight ones. In a loose market, rejection rates may fall because carriers are hungry for freight, not because demand is healthy. In a disrupted market, rejection rates may rise because capacity is avoiding specific lanes, appointment windows, equipment requirements, or service risk. The tender signal is real, but it is not always clean.

Accepted volume gets closer to executed demand. It asks: after the offers, rejects, backups, and reroutes, what freight actually made it into the moving network?

That makes it useful for procurement teams trying to separate true demand shifts from routing-guide noise. If tendered volume rises but accepted volume stays flat, the issue may be planning volatility, carrier compliance, or duplicate tendering. If accepted volume rises while spot rates remain elevated, the market may be absorbing real freight growth under tighter capacity. If accepted volume falls while tenders remain active, shippers should ask whether their routing guide is losing credibility.

The Current Market Shows Why One Signal Is Not Enough

The need for cleaner demand signals is obvious in recent truckload data.

Logistics Management reported that the May DAT Truckload Volume Index moved lower across all three major equipment types: van TVI was 233, down 9% from April and 8.3% year over year; reefer TVI was 172, down 10% sequentially and 15.7% annually; and flatbed TVI was 267, down 14% from April and 14.7% year over year. At the same time, spot rates moved higher. The national average spot van rate rose $0.22 from April to $2.89 per mile, reefer rose $0.24 to $3.35, and flatbed rose $0.19 to $3.65.

That combination is the headache: volumes down, rates up. DAT principal industry analyst Dean Croke told Logistics Management that lower volumes did not necessarily mean May was a weak freight market, because capacity supply had come down to meet demand and carriers in the spot market were being compensated for it. He also pointed to Roadcheck, immigration enforcement, and capacity migration toward contract freight for fuel surcharge certainty as factors affecting availability.

Cass data told a different but complementary story. Logistics Management reported that the May Cass Freight Index shipments reading was 1.041, down 1.2% year over year but up 3.0% sequentially, marking its fourth straight sequential increase. Expenditures rose 7.5% year over year and 5.3% sequentially. Cass noted that the year-over-year shipment gap was the smallest in 18 months and that a second-half volume recovery remained likely.

None of these signals is wrong. They are measuring different slices of the market. DAT reflects truckload load movement and rates. Cass reflects shipment activity and paid freight expenses across a large shipper base. Tender and rejection data reflects offers and carrier responses. Accepted truckload volume fills a gap between intention and execution.

The procurement mistake is treating any one metric as the freight market.

Accepted Volume Belongs in Procurement Reviews

Truckload procurement has become too dynamic for annual bid rituals alone. Mini-bids, lane repricing, routing-guide refreshes, and carrier scorecard reviews now happen throughout the year. Accepted volume can improve those decisions because it shows where freight is moving through committed networks rather than merely being offered to them.

For mini-bids, accepted volume helps identify whether a lane problem is demand-driven or compliance-driven. If accepted volume is rising in a region, procurement may need more committed capacity before spot exposure grows. If tender volume is noisy but accepted volume is stable, a full rebid may be overkill; the better move may be tightening routing-guide sequence, appointment discipline, or carrier communication.

For routing-guide refreshes, accepted volume can expose primary-carrier weakness. A carrier may look strong on awarded volume but weak on accepted volume if tenders are repeatedly falling to secondary options. That difference should affect award strategy. Procurement should reward carriers that accept and perform, not just carriers that bid aggressively.

For budget reforecasts, accepted volume gives finance a more realistic basis for freight spend. Rate pressure without accepted-volume growth may point to capacity contraction or service constraints. Accepted-volume growth with stable rates may point to genuine demand improvement. Accepted-volume decline with rising expenditures is a warning sign that cost inflation, accessorials, fuel, or lane imbalance is eating the budget.

Cleaner Data Still Needs Better Workflow

A better index does not automatically create better decisions. Shippers need a process for turning demand signals into execution controls.

Start by mapping each core lane across four views: tendered volume, accepted volume, rejection rate, and paid cost per mile. Then compare those views to service outcomes: on-time pickup, on-time delivery, fall-off frequency, detention, and claims. The goal is not to build a prettier dashboard. The goal is to identify where the operating model is lying to itself.

A lane with high tender volume, low accepted volume, and poor service needs routing-guide intervention. A lane with steady accepted volume and rising rates needs a pricing conversation. A region with rising accepted volume and shrinking carrier coverage needs capacity development before the next seasonal surge. A business unit with volatile tenders but stable shipments may need better order cutoff discipline, not a new carrier.

Accepted truckload volume is valuable because it moves the conversation closer to reality. It helps shippers see what the market actually carried, not just what planners hoped carriers would accept.
