Yep, how else can you warrant giving a ticket on private property like this. I would have thought that would alone have let him walk, I own 100 acres and if I decide to drive my car around my yard drunk does that mean I will get nailed with a felony?
A guy by me was intoxicated and accidentally backed his car, on his own driveway, over the leg of his grandson. His grandson had minor injuries, but the guy was charged with a felony DUI for an accident that occured on his own property.
Not a "felony", but yes, most states can ticket you for DUI, on your own property. In fact, they can ticket you, if you simply start the car, and do not even put it in gear.
