Out here, it's done all the time. Ag tractors coming out of fields, always leave a trail of mud turds on paved roads. I don't believe this state has any such law.I know a guy that got a ticket for that. Called littering a public roadway. Before trying the drive on a asphalt road check your state law on grass clipping etc.
Most states have a law similar to this.
No person shall place or throw, or permit anyone to place, throw, or shall permit to lie or remain upon the streets of the State, any earth, dirt, mud, sand or similar substance whatsoever, which has been deposited by the driving of any motor vehicle or truck upon the streets of the State.
My mud turds are always pretty large actually.Oh so it's you guys! I wondered how my car was getting covered in clay driving on the street
