They don't need to advise you of your Miranda rights unless they wish to interrogate you while you are in custody. Miranda is only an issue if there are questions about an alleged confession or other incriminating statements made by an alleged suspect while in "custody." There may, however, be other issues with your alleged circumstances. The there may be issues with the initial traffic stop, testing procedures, or other questions about the police officer's conduct. It depends on the alleged circumstances. Generally speaking, confessions are less of an issue with Operating-While-Intoxicated or Operating-While-Impaired charges because the prosecutor relies more on the testing information. I'd recommend you privately consult with an attorney and exercise your right to counsel.
