Record Diesel Prices Put Pressure on U.S. Trucking Companies

The national average price of diesel reached approximately $6.53 per gallon in September, setting a new record and surpassing the previous national high of about $5.81 recorded in 2022. Although the national average has eased somewhat from the September peak, fuel remains dramatically more expensive than it was a year ago.

In Ohio, the situation is particularly difficult for trucking companies. Diesel prices hovered around $6.65 per gallon on October 2, compared with approximately $3.66 per gallon at the same time last year, according to reporting by The Columbus Dispatch. That represents an increase of almost $3 per gallon in roughly one year.

Fuel Costs Are Creating a Cash-Flow Problem

The biggest challenge for many carriers is not simply the higher price of diesel. It is the timing of when companies have to pay for fuel compared with when they receive compensation from customers.

Trucking companies must purchase diesel immediately at the pump to keep trucks rolling and deliver freight. However, the additional fuel costs are often recovered through fuel-surcharge programs that are tied to specific fuel-price indexes and customer contracts. Those surcharges do not provide immediate reimbursement.

Fuel Surcharges Do Not Always Move as Quickly as Diesel Prices

Fuel surcharge systems are designed to help carriers and shippers share the impact of changing fuel prices, but the formulas and timing vary significantly between contracts. Some agreements use weekly fuel-price indexes. Others may have different adjustment schedules, regional benchmarks, baseline prices or mileage assumptions.

C.H. Robinson noted in its October freight-market update that the immediate concern for freight transportation is not only the price of diesel but also the timing between rising fuel costs and adjustments to shipper fuel surcharges.

Smaller Carriers and Owner-Operators Face Greater Pressure

The impact is particularly acute for smaller trucking companies and independent owner-operators.

Large enterprise carriers often possess revolving credit lines, negotiated fuel card discount networks, bulk terminal fueling, and diversified customer portfolios. Smaller operators typically operate on tighter cash reserves with limited borrowing capacity.

For an owner-operator, fuel is the single largest recurring cost for every loaded and empty mile. A truck consuming 200–300 gallons of diesel weekly experiences a severe jump in cash outlays even if total miles remain identical, wiping out take-home pay even when top-line gross revenue looks steady.

Entering a Fuel Shock After Years of Weak Freight

The timing of this diesel spike comes after several grueling years for commercial trucking following the post-pandemic freight boom. During that expansion, carriers added substantial capacity. When consumer demand normalized, overcapacity drove freight spot rates down to breakeven levels.

Now, while capacity is tightening, freight demand itself remains uneven across key freight corridors.

ATA Chief Economist Bob Costello emphasized that recent improvements in the freight market have been driven more by reduced carrier capacity (fleet attrition) than by genuine surges in underlying freight volume.

Higher Diesel Prices Can Push Freight Rates Higher

As fuel costs escalate, carriers must respond by negotiating higher base contract rates, tightening surcharge terms, or declining low-margin lanes.

However, contractual freight commitments negotiated months or years earlier limit a carrier's ability to immediately pass higher expenses onto shippers. Because fuel surcharges do not capture 100% of out-of-route, deadhead, or reefer auxiliary fuel consumption, carrier operating margins remain under intense pressure.

Regional Disparities in Fuel Pricing

National averages mask severe regional variances. West Coast pump prices trade at a substantial premium over Gulf Coast and Midwest markets due to regional refining constraints and environmental fuel specifications.

A carrier running regional routes in the Midwest faces a vastly different cost curve than a cross-country fleet routing through California, Washington, or Oregon, making fuel stop optimization and corporate card discounts paramount to survival.

Ohio Fleets Feel the Squeeze: Continental Express Example

Ohio illustrates how quickly fuel inflation disrupts fleet balance sheets. According to The Columbus Dispatch, Sidney-based Continental Express reported fuel costs roughly 75% higher than a year earlier. Company executives noted they cannot instantly hike rates on long-term shipper contracts, forcing the carrier to finance massive fuel outlays up front.

Ripple Effects on Retail and Consumer Goods

Because nearly all consumer staples, food, industrial components, and building supplies move by truck, sustained diesel increases inevitably work their way through wholesale distributors to supermarket shelves and consumer goods, exerting fresh inflationary headwinds on the wider economy.

For professional truck drivers, higher diesel prices alter daily operations and freight lane selections, even when company drivers do not pay for fuel out of pocket.

Motor carriers operating under tightened margins become increasingly selective about lane profitability, dispatch schedules, and equipment utilization. Fleets place renewed emphasis on progressive shifting, speed limiters, idle reduction policies, and minimizing uncompensated deadhead miles.

The impact of fuel inflation differs markedly across freight divisions:

For drivers compensated on a cents-per-mile basis, carriers with well-structured fuel surcharges and stable long-term contracts provide superior earnings protection compared to spot-market operators vulnerable to cash-flow crunches.

What Trucking Companies Are Watching Now

As the fourth quarter gets underway, motor carriers are balancing four interconnected metrics:

C.H. Robinson advised enterprise shippers that 2027 transportation budgets should anticipate elevated fuel expenses relative to historical norms, warning that refinery bottlenecks and global supply constraints will keep diesel volatile regardless of benchmark crude swings.

Conclusion: Operating in a High-Cost Environment

The U.S. trucking sector enters late 2026 under a demanding dual dynamic: fuel costs have escalated faster than conventional working-capital reserves can comfortably absorb, while freight demand has not yet rebounded into a full-scale boom.

Carriers with disciplined fuel hedging, robust shipper relationships, and efficient equipment will endure this test of balance sheets, while fleets unable to bridge the surcharge payment gap face mounting operational headwinds.
