Michigan Lets Farm, Logging Trucks Run Dyed Diesel On-Road
Governor Gretchen Whitmer declared a statewide energy emergency and signed Executive Order 2026-15, temporarily suspending Michigan's Motor Fuel Tax Act provisions that bar on-road use of dyed diesel by farm and wood harvester vehicles. The order lets vehicles carrying farm or wood harvester license plates run on dyed diesel on public roads without penalty.
The state said record-high diesel prices and supply disruptions tied to the Iran War are straining farmers and loggers during peak harvest season. Whitmer said the order aims to "keep work moving and reduce pressure on the people who keep our state's ag economy running," according to the press release.
The suspension took effect immediately upon signing and will end no later than Dec. 31, 2026. The order does not change federal fuel tax rules or dyed diesel restrictions outside Michigan; it applies only to vehicles operating under Michigan farm or wood harvester plates on Michigan public roads.
The release does not specify enforcement mechanics, how carriers should document eligibility, or whether any registration or notice is required to use the exemption.
What's next
- 2026-10-12: Executive Order 2026-15 takes effect immediately.
- 2026-12-31: Dyed diesel exemption for farm/wood harvester plates expires unless extended or rescinded.
