This was my first " fail " and I am NOT on probation . The conditions of my discharge were to go to evaluation ( done ) , Drinking Driver's Program ( done ) and have the ID installed in my car ( done ) . Do I just get the ID serviced or will this be a much bigger problem ?I have no idea why I failed. I have not had a drop of alcohol since my arrest in Jan, 2012 (13 months sober!). My heart about exploded when it said I failed. I would like to add that this was not a rolling re-test, just the initial start-up sample, therefore the car was not turned on, so there was no operation of the motor vehcle.
