I reside in Arizona and received a DUI. I was ordered to have an interlock device on my car for 1 year. The car is actually not in my name. A family member received 2 violations over .08 within 1.5 hrs. I question the accuracy of the device. This happened in June. I did not receive anything from the DMV informing me of a 6 month extension. Anyway it is now December and thought it was coming of in January and now not until July. I wasn’t aware that it must be contested within 15 days. Is there anything I can do?
