I am not on probation, but I do have an IID. I blew into it one morning and failed. I forgot that I used mouthwash! I waited 45 minutes and tried again and it passed. I am wondering if there are any legal consequences for having a failed test report. There was no "lock out", it simply requested a retest immediately, but I instead turned off the car and waited for the mouthwash to be completely out of my system. I am not on probation, but am required to have the IID in for a year. Can they charge me with another DUI for this??
