Montana's Dyed Diesel Pause for Farm and Log Haulers Ends Nov 23

What changed in Montana on October 9

On Friday, October 9, 2026, Montana Lt. Gov. Kristen Juras, acting as governor while Gov. Greg Gianforte was on a trade mission to India, signed an executive order that temporarily suspends enforcement of the state's dyed fuel rules for commercial motor vehicles hauling for agriculture and timber. NBC Montana and the Daily Montanan both reported the order, which cites recent global events that have squeezed the diesel supply chain. It runs 45 days and expires November 23, 2026.

For a Montana grain hauler or a log truck running out of the Flathead or the Bitterroot, that is a real break at the pump in the middle of harvest and fall logging. It is also a narrow break with a hard end date, and the details matter more than the headline. If you run in the state, our page on commercial truck insurance in Montana covers the routes, the weather, and the coverage that fits the work.

How Montana got here in four days

The sequence was quick and a little confusing. On Monday, October 5, President Trump signed a federal order widening the use of dyed diesel, which is exempt from federal fuel tax, to help with high fuel prices. Two days later, on October 7, the Montana Department of Transportation posted that the state statute banning dyed diesel on public roads remained in effect, according to the Daily Montanan. The federal order did not change state law.

The state order on October 9 is what actually opened the door in Montana, and only for a specific slice of trucks. If you heard about the federal order and filled up on red diesel on October 6 or 7, you were running outside the rules at the time.

Who is covered and who is not

The order covers commercial motor vehicles engaged in agriculture and timber related transport. It does not cover noncommercial vehicles like personal pickups and passenger cars, and the Daily Montanan noted that most dyed fuel violations the state finds are in pickups anyway. The order also does not change state fuel taxes. It suspends enforcement for qualifying trucks. It does not rewrite the tax code.

That leaves gray areas a small carrier should think through before relying on it.

• A truck that hauls cattle or grain on Monday and general freight on Wednesday is only doing qualifying work part of the week.
• Dyed diesel left in the tank does not know which load is on the trailer.
• Fuel taxes you report elsewhere, including on interstate miles, are a separate question from what Montana officers will enforce on Montana roads.

If your operation is mixed, talk to whoever prepares your fuel tax returns before you switch, and keep your load records tight so you can show what each trip was hauling.

The savings are real, and so is the pump problem

Dyed diesel usually runs about a dollar a gallon cheaper because it carries no state or federal fuel tax. Jim Schwehr, who owns Done Right Trucking, told NBC Montana he is paying roughly $33,000 more per week in fuel across his 27 trucks, yet he did not expect the order to change much for him because many Montana fuel stops that sell dyed fuel only have one pump for it. For a single truck owner-operator, that can mean a long wait or a detour that eats into the savings.

Enforcement does not go away for everyone else. Montana Motor Carrier Services officers find dyed fuel through probable cause stops, tips, and watching dyed fuel pumps, and fines climb with repeat offenses. The red dye also leaves a residue in the fuel system that shows it was used.

Plan for November 24 now

The question nobody has answered yet is what happens to dye traces in your tank once the order ends. The Daily Montanan reported that farm groups in other states have already raised it. The safe move is to stop fueling with dyed diesel well before November 23, run the tank down on clean taxed fuel, and keep the receipts that show when you switched back. A stop on November 30 with red residue and no paper trail is not a fight you want.

None of this touches your insurance policy directly, but it is a good moment to check that your coverage matches what you actually haul. Farm and log hauling in Montana means gravel roads, steep grades, early snow, and wildlife on two lane highways. Physical damage coverage protects the truck itself when a slide off or a deer strike happens, and motor truck cargo coverage protects the grain, cattle, or logs on the trailer, with limits and exclusions that need to fit the commodity.
