Trump Signs Executive Order Expanding Access to Red Dye Diesel
President Donald Trump signed an executive order on Monday, October 5, 2026, aimed at lowering skyrocketing diesel prices by temporarily allowing anyone to purchase tax-exempt "red dye" diesel for highway use. The order, announced at a rally in Nebraska, seeks to provide relief to truckers, farmers, and consumers facing diesel prices that have surged more than 30% in recent months due to the war in Iran.
"Tonight I'm going to sign a historic executive order to officially waive the off-road requirement and allow anyone to purchase tax-free red dye diesel for any reason," Trump told the crowd, after admitting he didn't "know what the hell" red dye diesel is. The White House fact sheet states the order directs the secretaries of transportation, agriculture, defense, and the Treasury to expand access to tax-exempt diesel and encourage states to suspend their diesel taxes. The administration claims the move will save typical truckers more than $100 per fill-up and help bring down the cost of goods, including groceries.
Red-dyed diesel is traditionally exempt from federal excise taxes because it is intended for off-road uses such as farm equipment and construction machinery. The fuel is dyed red to allow law enforcement to easily detect its illegal use on public roads. Federal tax on on-road diesel is 24.4 cents per gallon, and states levy additional taxes. With diesel prices at record highs—averaging $6.32 per gallon nationally on Tuesday, up from $3.76 before the Iran war—the administration is under intense pressure to act before the November 3 midterm elections.
What Is Red Dye Diesel and Why Is It Tax-Exempt?
The Basics of Dyed Diesel
Red-dyed diesel, often called "off-road diesel," is a type of fuel that is chemically identical to regular diesel but is marked with a red dye. This dye serves as a visual indicator that the fuel is not subject to federal and state motor fuels taxes. It is intended for use in off-road vehicles and machinery, including agricultural equipment, construction vehicles, and generators. Because it is untaxed, red-dyed diesel is significantly cheaper than on-road diesel.
The tax exemption exists because off-road vehicles do not use public highways, so they are not subject to the taxes that fund road maintenance and infrastructure. However, using red-dyed diesel on public roads is illegal in most states, and violators can face large fines, penalties, and even tax evasion charges. The dye is designed to be difficult to remove, and law enforcement can easily test fuel to determine if it is dyed.
The Executive Order's Provisions
Trump's executive order does not eliminate the federal tax on diesel, as only Congress has the authority to do so. Instead, it instructs Treasury Secretary Scott Bessent to "defer certain diesel fuel tax payment obligations and to provide penalty relief to the extent permitted by law." This means drivers who switch to red-dyed diesel could potentially owe back taxes later, according to experts. The order also does not resolve Environmental Protection Agency (EPA) or state restrictions on dyed diesel, and it does not waive state bans on its use on public roads.
The administration is encouraging states to suspend their own diesel taxes and waive restrictions on red-dyed diesel. Some states, like Texas, have already taken action. On September 28, Governor Greg Abbott issued a statewide disaster proclamation to allow expanded use of dyed diesel on Texas roads, citing record prices that put agriculture and freight industries at risk. The proclamation also raised allowable weight limits for fuel, agricultural, and timber loads and requested that the EPA waive federal ultra-low sulfur diesel requirements.
Industry Groups Warn of Risks and Uncertainty
Caution from Fuel Marketers
Following the executive order, the Energy Marketers of America (EMA) warned gas stations to "proceed with caution." The group noted that "whether relief is available, whom it covers, and on what conditions depend on Treasury determinations and guidance not yet issued." The EMA emphasized that "deferral is not forgiveness" and that the order does not resolve EPA or state restrictions on dyed diesel.
Other industry groups, including the Society of Independent Gasoline Marketers of America and the National Association of Truck Stop Owners, echoed these concerns. In a note to members, they said they do not expect most reputable diesel retailers to sell red-dyed diesel for highway use. "First, the tax is still owed, so there's limited upside," they wrote. "In addition, the logistical challenges outweigh any visible upside: Residual dye lingers in tanks and fuel systems." They warned that for most fuel sellers, "the liability and customer risk outweigh any temporary, uncertain benefit."
Skepticism on Savings
Experts are also skeptical that the order will deliver widespread savings. Patrick De Haan, a petroleum analyst at GasBuddy, told CBS News that "it might lead to savings for some, but there are a lot of details that will prevent this from having widespread relief." He questioned whether drivers who switch to dyed diesel will eventually receive a tax bill. "Whether anyone who makes the switch to dyed diesel suddenly gets a tax bill is the most unanswered question I have," De Haan said.
A group representing independent long-haul truckers suggested the move would provide minimal relief, stating that "allowing the wider use of red-dyed diesel will provide minimal relief. Market stability" remains a concern. The mixed signals from industry and experts suggest that the executive order may not achieve its intended effect of significantly lowering costs for consumers and businesses.
Political and Economic Stakes Ahead of Midterms
Pressure to Lower Fuel Costs
The executive order comes amid a highly charged political environment. Voters in both parties cite high gas prices and the rising cost of living as their top issues. The Trump administration has been under intense pressure from Republican candidates to address diesel prices, which have risen by more than 30% in recent months. The announcement was made in reliably Republican Nebraska, where GOP Senator Pete Ricketts faces an unexpectedly strong challenge from independent Dan Osborn, one of several Senate candidates who could flip seats long held by Republicans.
Trump framed the order as a way to help truckers and bring down the costs of other goods. "This will save typical truckers more than $100 every time they fill their tanks and drive down the costs of other goods, including groceries," he said. However, the order's temporary nature—it defers the federal excise tax for the remainder of 2026—and the lack of clarity on state enforcement could limit its impact.
State-Level Actions and Federal Tensions
Texas Governor Greg Abbott's preemptive action to waive dyed-diesel restrictions highlights the patchwork nature of fuel regulations. While Texas has moved to allow dyed diesel on its roads, other states may not follow suit, leading to a "convoluted patchwork" of enforcement, as CBS News noted. The White House said it is working with states to encourage them to waive their bans, but no uniform solution has emerged.
Additionally, the order does not address federal ultra-low sulfur diesel requirements, which could limit the availability of compliant fuel. Abbott has requested a temporary Clean Air Act waiver from the EPA to allow more fuel to reach Texas pumps. Without such waivers, the impact of the executive order could be uneven across the country.
Broader Implications for Fuel Policy and Consumers
A Temporary Fix with Long-Term Questions
The executive order is a stopgap measure that defers taxes rather than eliminating them. This raises questions about what happens after 2026, when the deferral ends. Drivers who take advantage of the order could face a significant tax bill down the road, and fuel retailers may be reluctant to participate due to the risk of liability. The order also sets a precedent for using executive action to address fuel prices, which could have implications for future energy policy.
Market and Environmental Concerns
The fuel industry's cautious response underscores the logistical and regulatory hurdles. Red-dyed diesel leaves residual dye in tanks and fuel systems, which can contaminate regular diesel and cause operational issues. Moreover, the EPA's restrictions on sulfur content are in place to reduce air pollution, and waiving them could have environmental consequences. The order's focus on short-term relief may overshadow these longer-term concerns.
As the midterm elections approach, the success of this order will likely be judged by whether it actually lowers prices at the pump. With industry groups warning of limited upside and experts skeptical of widespread savings, the administration's gamble may not pay off. For now, the true cost of red-dye diesel remains uncertain—both for drivers and for the environment.
