DUI w/minors in the car is automatically automatically a aggravated DUI in Arizona, class 6 felony, the penalties are super harsh here to begin with, they don't screw around with endangering kids like that. I take it it's probably similar in Jersey.

Glad you're ok and hopefully the lady receives the proper punishment so she learns her lesson well and good.
