Your DUI record goes back for your entire lifetime. This would count as a 3rd DUI and as for the suspension portion of the case, you are not considered a first time offender and are facing either 1 or 3 years of a hard suspension, meaning no driving relief is available. A 3rd time DUI can be charged as a Class 4 felony. You need to hire an experienced DUI attorney in your local area.
