Well, these are the consequences we've got. He's not facing any jail time unless he violates the terms of his DWI probation, which last until September. 12 months jail is hanging over his head, though he'd have to do some really serious violating to get that.
He also must complete the ASAP (Alcohol Safety Action Program) requirements. He also has been given a restricted license, to drive to and from work, to and from medical appointments, and to and from ASAP meetings, and getting caught driving would be a problem, though probably not jailable the first time.
I believe Mr. Trad was most interested in not getting a DWI conviction in the first place, though, which is why he tried to shift the blame first to Ms. X, the young lady in the car, and then to his friend who wasn't even there. That didn't work, but he tried.
He also has the consequence of being the subject of all this attention, forever lasting on the Internet, and the focus of the unforgettable #beltwaysex hashtag. So there's that.
