You will need your mom and/or friend to write a statement to Smart Start and the DMV indicating they were the ones with a BAC who started the vehicle. Unfortunately, it is your responsibility if you had the IID registered in that car under your name.

This reply should NOT be considered a legal opinion of your case / inquiry. At this time I do not have sufficient factual/legal documentation to give a complete answer to your question and there may be more to the issues you raised then I have set out in my brief reply.
Along with the order of suspension, should have been a notice to request a hearing within a certain time frame. You need to request the hearing before that allowed time expires. The assistance of an attorney is probably critical, even though there are no provisions for appointed counsel in the case of DMV hearings.
