New Delhi: United States President Donald Trump signed an executive order temporarily allowing expanded access to tax-exempt red-dyed diesel on public roads. The decision is aimed at easing fuel costs in the US.
“For many years, farm vehicles, construction equipment and other off-road vehicles have used what’s known as red-dyed diesel. You know what that is? I don’t know what the hell it is, but whatever it is, it is supposed to be very good,” Trump said at a campaign rally in Grand Island, Nebraska, on 5 October. He announced the order at the same rally.
He added that the order would “officially waive the off-road requirement and allow anyone to purchase tax-free red-dye diesel for any reason”.
Trump claimed that the typical trucker would save more than $100 per fill-up and that the measure would also lower costs for farmers, thereby reducing the cost of other goods and groceries.
The executive order, detailed in a White House fact sheet, defers payment of the federal excise tax on dyed diesel used on-road for the remainder of 2026, without interest or penalties.
It also directs US federal agencies, including the Treasury, Agriculture, Transportation, and Defense departments, to expand access to the fuel and encourages states to suspend their own diesel taxes.
What is red diesel?
Red-dyed diesel—also called red diesel or dyed diesel—is chemically nearly identical to regular highway diesel. The only difference is a red dye added as a marker so authorities can detect illegal highway use.
Under earlier rules, the fuel was restricted to off-road applications such as farm equipment, construction machinery, and generators. It is exempt from the federal highway excise tax of 24.4 cents per gallon, as well as many state taxes.
Previously, using the fuel on public roads carried the risk of fines and back taxes. Trump’s order suspends federal enforcement of that restriction until the end of the year.
Soaring diesel prices
US diesel prices hit a record high of $6.529 per gallon in late September, according to data cited in multiple reports. The rise was linked to supply disruptions tied to the US-Israel War on Iran, refining interruptions, and Ukrainian attacks on Russian energy infrastructure.
While average prices have eased slightly since the peak, they remain sharply elevated compared with levels before the Iran War began in February.
Trump has repeatedly blamed the price spike primarily on Ukrainian strikes on Russian refineries rather than disruptions in the Strait of Hormuz, and has urged European allies to release emergency diesel stocks.
On Friday, the G7 and partners reportedly committed to releasing up to 100 million barrels of diesel and crude from reserves over the next four months.

Would red diesel impact price?
Supporters of the order argue it will deliver immediate tax relief to truckers, farmers, and other diesel users who can access the fuel. Analysts, however, have cautioned that the practical effect may be limited.
Patrick De Haan, head of petroleum analysis at GasBuddy, wrote on social media that while the order “sounds big”, most drivers will not benefit because “states still enforce their own rules, it’s not truly tax-free, and it doesn’t add a single gallon of supply.”
Red diesel is primarily sold at specialised farm, co-op, and construction fuel depots rather than ordinary gas stations, and increased demand could raise prices for the agricultural users who have long relied on it.
“One doesn’t have to pay federal and state excise taxes on dyed diesel, but it really doesn’t shift the amount of overall diesel manufactured for domestic purposes,” Tom Kloza, chief energy adviser at Gulf Oil, told Reuters.
Other analysts interviewed by the news agency echoed the limited impact.
Gregg Ibendahl, an agricultural economics professor at Kansas State University, said the measure “would help less than it sounds like”. Preben Sørli of Rystad Energy noted that it “would not change the underlying wholesale diesel price” and would mainly reduce federal tax revenues rather than alter supply or market fundamentals.
