If you were drunk on a horse, would that be DUI?
I think the argument that the horse is more in control of the situation than a drunk human. lol "But your honor, he knew his way home, all I had to do was sit there" LMAO
If you were drunk, how could you get on the horse?
For that matter, wouldn't the saloon owner be partially at fault for giving you back your reins?
Yep. Also there have been people arrested on bicycles and riding lawn mowers.
I was in a bar years ago, a guy drove a back hoe there, they got him for dui.
