The police officer never gave me a miranda warning following my drunk driving arrest in ...

In a DUI case, you're not entitled to a Miranda Warning in the same sense that you might be in other cases. The courts have typically ruled that your interest against self-incrimination is outweighed by the public's interest in having people that are potentially dangerous on the roadways. What does that mean? It means that although you're not entitled to that Miranda Warning, if you are detained and if you are asked specific questions that elicit an incriminating response, you may be able to get those statements thrown out. If you're asked, "How many drinks have you had," and you say, "I've had two beers." That statement may not be admissible in court absent a Miranda Warning. That's something to talk to your lawyer about to see whether there's any admissions in those types of contexts that might be able to be excluded in court. As it relates to the overall case, there's no obligation to be Mirandized for a DUI investigation.
