A DWI or DUI can be a significant charge that has a lasting impact on your life. Even if you are not convicted in the end, the impact of the charges could result in changes in your social circle, result in termination from your job or other unforeseen consequences.
A DWI or DUI are essentially the same thing. In both cases, a conviction proves that you were too intoxicated to drive. Driving under the influence or driving while intoxicated are both against the law, with a per se limit of .08%.
