They did away with Driving Under the Influence (DUI) here in Arizona.
That is true, you can't get a DUI in Arizozna now.
Unfortunately they replaced DUI with the new all encompassing Operating Under the Influence (OUI) law which covers everything from horses, bicycles and boats to even a frgg'n skate board or unicycle and I wouldn't surprised if they managed to cite you for walking drunk 'operating' your cell phone.
That's OK with me, I get tons of new 'Transpiration Challenged' customers especially during the holidays when Sheriff Joe does his random OUI checkpoints and it does help ease traffic hehehe ;-}
