Operating Costs and Fuel Volatility Hit Fleet Bottom Lines

If you have taken a look at carrier balance sheets lately, you know that managing a fleet this fall is less about chasing spot volume and more about surviving the expense side of the ledger. According to reporting from Trucking Dive, the American Transportation Research Institute identified diesel price volatility as the single top concern for trucking industry leaders in 2026. While broader macroeconomic anxiety has started to settle down, raw operating costs like fuel and driver retention have taken center stage.

That expense inflation is hitting even the largest dedicated operations in the country. Trucking Dive reported that J.B. Hunt saw a 22 percent year over year drop in its dedicated segment operating income for the third quarter. The carrier pointed directly to elevated driver expenses, higher medical claims, and rising insurance premiums as the primary drags on profitability. When dedicated contract margins compress by more than a fifth, it tells you everything you need to know about the cost floor carriers are trying to build under their rates.

To manage these fuel shocks, fleets are trying a bit of everything. Trucking Dive reported that grocery distributor UNFI is relying heavily on fuel hedging strategies alongside routing software to trim unnecessary deadhead miles while diesel hovers at elevated levels. Other fleets are looking at alternative power to cut fuel bills entirely. Trucking Dive highlighted Sagepoint Logistics, whose parent company produces its own renewable natural gas. The carrier is doubling the size of its RNG fleet, leveraging fuel that can run up to $1.50 per gallon cheaper than standard diesel. Out in California, Ability Tri-Modal Transportation Services is taking old diesel tractors and retrofitting them into electric units equipped with swappable batteries that can be exchanged in minutes.

Meanwhile, fuel security has become its own headache on the ground. Land Line reported that law enforcement in Southern California recently charged a theft crew accused of using siphons and lookouts to steal diesel straight from parked trucks, an ongoing operation authorities had been tracking since August.

Reefer Rejections Rise as Regional Networks Expand

On the freight movement front, temperature-controlled capacity has tightened up noticeably over the last few weeks. FreightWaves reported that national refrigerated truckload rejections have soared, with 1 in 5 reefer loads currently being turned down by carriers. A combination of fall harvest demands and rising diesel overhead is pushing reefer operators to demand higher spot premiums or stick strictly to their profitable dedicated lanes.

That tightness is not limited to temperature-controlled freight. A market sitrep cited by FreightWaves showed that overall tender rejections across the market are running at 2.5 times the levels seen last year, while contract rates have moved up 18 percent. The report notes that the dynamic between buyers and sellers of transportation is shifting quickly, forcing shippers to move beyond standard operational courtesy and focus on becoming true strategic partners to secure consistent trailer capacity.

Carriers are also adjusting their physical footprints and technology stacks to stay flexible. FreightWaves reported that regional Less-Than-Truckload carrier A. Duie Pyle is expanding its network across the Northeast and Midwest by adding a new service center in the Cincinnati area and opening an integrated warehouse facility in Camp Hill, Pennsylvania. On the hardware side, FreightWaves reported that PACCAR plans to launch PACCAR Connect in early 2027. The factory platform will integrate Kenworth and Peterbilt trucks directly into Platform Science's Virtual Vehicle app marketplace, giving fleet operators direct cab connectivity without needing third-party aftermarket hardware installations.

Geopolitical Shifts, Cargo Theft, and Trade Barriers

Macroeconomic headwinds and trade friction continue to complicate long-range planning for domestic and international supply chains alike. FreightWaves SONAR reported that the Federal Reserve raised its target federal funds rate by 25 basis points to a range of 3.75 percent to 4.00 percent on September 16. Fed Chair Kevin Warsh noted that inflation remains too high, making capital equipment financing and facility expansions more expensive for fleet operators looking to replace aging tractors.

International lanes are seeing their own share of disruption. FreightWaves SONAR reported that while Trans-Pacific ocean container rates reached yearly highs following a temporary trade truce between the United States and China, geopolitical risk remains high. Recent Houthi attacks on Saudi Arabian infrastructure have raised fresh concerns about Red Sea shipping lanes just as ocean carriers prepare for 2027 contract discussions.

Closer to home, cross-border trade with Canada took a sharp turn. FreightWaves SONAR reported that on September 29, the United States escalated an ongoing trade dispute past simple tariffs by imposing a straight prohibition on imports of Canadian dairy, alcohol, and large-displacement motorcycles. That outright ban follows earlier tariff increases enacted on September 8, leaving regional haulers on northern border lanes scrambling to adjust to sudden cargo bans.

High-value freight security also remains a critical operational risk. FreightWaves reported that detectives in California are investigating the theft of nearly $1 million worth of Pokémon and sports trading cards from a FedEx truck. The driver discovered a missing cargo-door lock outside a grading facility, serving as a blunt reminder that targeted cargo theft remains a major hazard for high-value shipments.

Regulatory Fairness and Cross-Border Driving Realities

Administrative updates and safety enforcement are also altering daily fleet operations across the country. Land Line reported that all 50 states have now fully implemented the updated DataQ process. The system is designed to give motor carriers and drivers a fairer, more consistent administrative avenue to challenge questionable safety violations on their records.

State legislatures are also toughening up on driver behavior. Land Line reported a surge in new state laws and pending bills aimed at aggressive driving, illegal passing, and excessive speeding, meaning fleet managers will need to keep a tight leash on safety scores to avoid escalating insurance premiums.

Finally, border logistics continue to reshape regional routing. Land Line reported that evolving shipper strategies for cross-border Mexican freight are creating new hauling opportunities for domestic owner-operators based well north of the southern border, as supply chains move away from traditional border-zone drayage patterns toward longer domestic legs.

What this means for your freight rates

With fuel volatility topping carrier cost concerns and contract rates already up 18 percent over last year, small fleets simply cannot afford to haul cheap freight while diesel and insurance bills keep climbing. When one out of every five reefer loads gets rejected, carriers are sending a clear signal that they will prioritize network margin over sheer volume. Shippers who assume they can hold contract rates flat entering late 2026 are going to find themselves relying on an expensive spot market when fall produce and holiday retail surges hit regional lanes.

To make sure you are not overpaying for trailer space or getting caught flat-footed by sudden rejection spikes, you need to track lane-level cost reality as it happens.
