Different states call it different things, but they are all the same in Louisiana. DWI (driving while intoxicated) is the same as DUI (driving under the influence) and OUI (operating under the influence). In fact, in Louisiana all are based on under the influence and not intoxication theory, meaning it is no longer good to tell a police officer “I only had 2 beers”, or “a sleeping pill last night”. Both could be an admission used against you in court. Remember that you still have a 5th amendment right to remain silent and not incriminate yourself.
