Generally, no person may use dyed diesel fuel in a motor vehicle used on public roads. However, there are a few exceptions to this rule:
- Persons operating motor vehicles that have received fuel into their fuel tanks outside of this state in a jurisdiction that permits introduction of dyed diesel fuel into the fuel supply tank of highway vehicles;
- Uses of dyed fuel on the highway that are lawful under the Internal Revenue Code, compiled in 26 U.S.C., and regulations, including state and local government vehicles, and buses, unless otherwise prohibited; and
- Agricultural vehicles used solely for the purpose of transferring a person's harvested crops from the field to the person's storage facility for the harvested crops; provided, that the distance traveled on the public highways does not exceed five miles.
