It is illegal to operate a riding lawnmower or farm tractor on a public highway while intoxicated.

The Law

Driving under the influence applies to far more than just cars and trucks in Wisconsin. Drunk driving laws specifically cover farm tractors, ATVs, and even riding lawnmowers if they are operated on public roads. Given the state's rural landscape, a few too many beers on a John Deere has led to more than a few legitimate arrests.
