Trump Executive Order Lets Truckers Use Tax-Exempt Dyed Diesel on Highways Through Year-End

President Trump signed an executive order on the evening of Oct. 5, 2026, that temporarily allows truckers and other highway drivers to use red-dyed, off-road diesel on public roads and defers the federal excise tax that normally applies to on-highway fuel through Dec. 31, 2026, according to the White House's text of the order and a companion fact sheet. CNBC reported that Trump displayed the signed order to the crowd during a campaign rally at the Pinnacle Bank Expo Center in Grand Island, Nebraska.

What the Order Changes

Dyed diesel is fuel sold for off-road uses such as farm equipment, construction machinery and heating, and it is normally exempt from the 24.4-cent-per-gallon federal excise tax that applies to diesel sold for highway use, CNBC reported. Using that dyed fuel in a vehicle on public roads is ordinarily illegal and can trigger fines for tax evasion, CNBC said. The new order directs the Treasury secretary to defer payment of the taxes imposed by 26 U.S.C. 4041(a)(1)(A) or 26 U.S.C. 4041(b)(1)(B) that are incurred during the period running from Oct. 5 through Dec. 31, 2026, according to the order's text. The deferral is to be granted, to the extent authorized by law, "without any penalties, interest, additional amount, or addition to the tax."

The White House fact sheet frames the practical effect as enforcement discretion, stating that "the Administration, and State Governors, can exercise their enforcement discretion to halt inspections and waive the tax liability that users would face for on-road use of dyed diesel." The administration says the move could save truckers more than $100 per fill-up, a figure cited in both the fact sheet and CNBC's reporting.

Deferred, Not Forgiven

Importantly, the order defers the tax liability rather than eliminating it outright. The text separately directs the Treasury secretary to "explore avenues, including legislation, to eliminate the obligation to pay the amounts deferred," which means forgiveness of the underlying liability is not automatic and would require further action.

The relief is also conditional on a legal determination. Within five days of the order, the Treasury secretary, in consultation with the Secretary of War, must determine whether relief is authorized under 26 U.S.C. 7508A, including whether a "qualifying event" has occurred and which taxpayers are affected. Treasury must then issue implementing guidance spelling out the legal basis for relief, which taxpayers and locations are covered, and the date by which any postponed taxes must ultimately be paid.

On the enforcement side, the order instructs the IRS to announce it will not impose penalties under 26 U.S.C. 6715(a)(1) or 6715(a)(2) when dyed diesel is sold for highway use or used on the highway between Oct. 5 and Dec. 31, 2026, and to address relief from penalties tied to missed semimonthly tax deposits. Treasury is also told to assess how the IRS should allocate inspection and fuel-sampling resources during the relief period and to make that determination public. Separately, the order specifies that the Federal Motor Carrier Safety Administration will "continue all compliance enforcement measures, including audits, inspections, and monitoring programs, as provided for by law," meaning the order touches tax enforcement, not motor-carrier safety oversight.

State Taxes Remain a Separate Question

The federal order does not waive state fuel taxes. The White House fact sheet notes that on-road diesel "is subject to state and federal excise taxes," and the order tasks the White House Office of Intergovernmental Affairs with engaging states and encouraging them to "adopt policies that correspond to" the federal deferral, rather than mandating that they do so. CNBC reported that several states had already relaxed restrictions on tax-exempt diesel this year to help drivers cope with surging fuel prices; CNBC did not detail the terms of those state-level changes, and the federal order leaves state enforcement decisions to the states.

Supply Coordination for High-Demand Areas

The order also directs the Secretary of Agriculture to coordinate with agricultural cooperatives, rural fuel distributors, farm supply organizations and other agricultural stakeholders "to ensure adequate distribution of dyed diesel for their use in high-demand areas," and to encourage similar state-level action, according to the order's text and the fact sheet. This suggests the administration anticipates localized supply pressure on dyed-fuel distribution networks as demand patterns shift, though the order does not detail current dyed-diesel storage or dispensing capacity.

Why Now: Diesel Prices at Record Levels

The order follows a run-up in diesel costs. CNBC reported that the U.S. national average price of diesel topped $6 a gallon in September for the first time ever, which the outlet attributed to fuel supply disruptions tied to the conflicts in Ukraine and Iran. CNBC also cited Bob McNally, president of Rapidan Energy, saying Americans are spending about $700 million more per day on gasoline and diesel combined than they did a year earlier.

The White House fact sheet attributes tight global diesel supply to the Russia-Ukraine war and a shortage of refining capacity worldwide, specifically naming what it calls "Democrat-led States that chose to shut down their refineries in the name of 'Green Energy' policies." That causal framing reflects the administration's own characterization rather than independently verified industry data on refinery closures. The fact sheet also notes that the Department of Transportation had earlier waived hours-of-service rules for drivers hauling gasoline and diesel shipments, allowing them to drive additional hours, as part of the broader push to ease fuel costs.

What the Order Does Not Guarantee

The order explicitly states that it "is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States," and its implementation is subject to applicable law and the availability of appropriations. Combined with the conditional 7508A determination and the open question of whether Treasury will ultimately seek legislation to forgive rather than merely defer the tax, truckers and fuel distributors are working with a relief measure whose final financial outcome is not yet settled.

Bottom Line

The executive order gives truckers and fuel users a temporary, enforcement-based path to use untaxed dyed diesel on highways through the end of 2026, with the White House estimating savings of more than $100 per fill-up. But the underlying federal tax liability is deferred rather than canceled, implementation hinges on a Treasury legal determination due within days of signing, and state excise taxes are untouched by the federal action. The measure arrives against a backdrop of diesel prices that CNBC reported crossed $6 a gallon nationally for the first time in September, a level the administration is citing as justification for the relief.
