It matters not at all whether or not your DUI arrest results in a conviction or not. The court side of a DUI has nothing at all do with the actions a BON will take once you are arrested for DUI, or any other crime. Once you are arrested, you have a permanent RAP sheet, that will never be cleared, regardless if you win an expungement. If you have a license, you must report your arrest to your BON. The chances are very good that your license will be revoked, or that you will be unable to pay for the various programs most BONs require after a DUI arrest (regardless if convicted or not). If you are still in school, in an increasing number of states now, a DUI arrest will prevent your BON from granting you a license. In the majority of DUI arrests, a lawyer has no bearing on your outcome, other to advise you to plea to the lesser charge levied against you (most DUI arrests incur multiple charges, in fact, to increase the likelihood of your taking a plea, as if the prosecutor has granted you some sort of a favor?). Also, if you are a student- a DUI may prevent you from attending clinicals, based on your hospital rules. DUI is the number one criminal offense now in the US, 1.5 million per year. And every year the sentences are being increasingly harsh and permanent, by the courts, by the MVDs, and by the BONs, etc.
