Clur, I got my DUI in 1990 or so - I was charged with Driving Under the Influence, as well as driving with a BAC over a certain limit, (there’s your two charges) as well as improper lane usage and some other stuff. So yeah, it’s two separate charges.
Sounds like a bad night for the alleged offender… My husband was once involved in a case where the guy had multiple strike offenses in a single, wild night of crime and violence. Didn’t turn out well for the guy, as I recall… I think he racked up all three strikes in the end, but I’m not 100% sure, so I’ll check.
