So you do have to go to the DMV to get your license changed when you get the box removed? Mine has “20. BAC .04 Until 08-06-16/Ignition Interlock Until 08-06-14.” Since I still have a 2 year BAC limit afterwards, and the dates are clearly printed, I shouldn’t have to get my license changed until 2016. Well, it seems like common sense but it is the DMV so who knows, lol. I’m only curious right now because I work construction and I have a job starting soon in SC so I’ll have to be taking time off of work to drive back to NC to make my appointments. It’ll be good to be prepared with as much information as possible to tell my bosses for when that day finally comes and I will no longer have my car be ravaged by this machine.
