For those who don't know, DUI and DWI is NOT the same. DWI is a more serious offense. DUI is driving under influence, which means after having a couple of beers. DWI is Driving WHILE INTOXICATED, that is after having 4-5 shots of hard liquor. DWI is a criminal case in many states. So if your friend got caught for DWI, then he better get a good lawyer.
