U.S. Diesel Prices Hit Record Highs as Multiple States Roll Out Tax Relief Measures
nashnova research
U.S. diesel prices touched a record $6.53 per gallon before settling at $6.44, driven by supply disruptions and geopolitical conflict; the federal government and over a dozen states are now racing to cut fuel taxes and loosen regulations ahead of the midterm elections.
How high have diesel prices gone?
AAA data shows the national diesel average hit $6.44 per gallon on Sept. 28, after touching an all-time peak of $6.53 a week earlier.
That is roughly $2.77 more than a year ago. This means → filling a standard truck tank now costs nearly double what it did last year.
Texas averaged about $5.90 per gallon on the same day, up roughly $2.70 year-on-year — truckers and farmers are bearing the brunt.
Why is supply so tight?
Three supply lines are squeezing at once: U.S. military action against Iran + Ukrainian strikes on Russian refining facilities + a sustained drawdown of global inventories.
In plain terms = the places that produce oil are at war, the facilities that refine it are being hit, and stockpiles keep shrinking — all three colliding at once.
The EIA warned on Sept. 9 that global distillate output — the category that includes diesel — will stay below last year's levels for the coming months, keeping U.S. diesel stocks low and prices elevated.
What is the federal government considering?
The Trump administration is weighing looser restrictions on red-dyed diesel — a type of diesel normally reserved for off-road farm use and exempt from most federal fuel taxes.
This means → if enacted, some buyers could legally run cheaper "farm diesel" on highways, effectively sidestepping the federal fuel tax.
Trump himself voiced support for banning diesel exports outright — keeping supply domestic to push down prices at home.
What emergency measures are states taking?
Texas: Governor Greg Abbott declared a statewide disaster, expanding highway use of red-dyed diesel, raising weight limits for fuel and farm transport, suspending low-emission diesel rules, and asking the EPA for temporary waivers on ultra-low-sulfur diesel requirements.
Alabama + Oklahoma: both suspended red-dyed diesel restrictions for 120 days, letting farm-grade diesel onto public roads.
Nebraska + Louisiana: allowed road-registered vehicles to use tax-exempt dyed diesel; Nebraska also offered refunds on diesel tax paid for hauling seasonal crops and livestock.
Is gasoline getting relief too?
Georgia suspended state gas and diesel taxes for 30 days; Indiana paused gasoline sales tax; Kentucky cut its gas tax by 10 cents and froze any 2027 increases.
California + Michigan: both switched early to cheaper winter-blend gasoline, bypassing stricter summer-formula requirements.
Massachusetts: the governor plans legislation to suspend the 24-cent-per-gallon gas and diesel tax for two months, requiring retailers to pass the cut through to pump prices.
Will any of this actually work?
The EIA expects prices to begin easing in early next year — but only if Middle East output recovers and alternative shipping routes around the Strait of Hormuz come online.
In plain terms = state tax cuts are painkillers; the real cure is a global supply recovery, and that depends on how the wars play out and whether producers ramp back up.
This reflects a political reality: with midterms approaching and Trump's economic approval under pressure, both federal and state officials are racing to use short-term tools to hold fuel prices down.
