I got a Dui, Dwi and a Dui per se in Md back in 2010. My punishment was a PBJ "Probation before Judgement". I got probation for a year, Alcohol education and court fines. I just recently got another DUI in Virginia (Sept 2012) with a BAC of .19.
The definition, charges, and penalties for driving under the influence (DUI) vary by state and depend on a number of factors.
After you are arrested for DUI, getting the charges against you dropped or reduced will require you to develop a defense.
