An Ag CMV is exempt from registration under s. 341.05(17) Wis. Stats.
An Ag CMV Self-Certification form (MV2580) is available on the WisDOT website at AgVehicles.DOT.wi.gov. MV2580 is not a required form but provides a reference for operators and law enforcement.
A registered vehicle may also operate under the AgCMV definition without needing to remove its registration plates.
If my Ag CMV isn’t registered, can I use dyed fuel?
