DUI and DWI are crimes committed when a person operating a car, motorcycle, or other vehicle is under the influence of (1) alcohol, (2) illegal drugs, and/or (3) prescription medication. Laws vary from state to state as to the legal blood-alcohol level and the consequential punishment. In most instances, a first-time DUI/DWI offender will be charged with a misdemeanor (minor crime). If someone was injured in the accident, the charge may result in a felony (serious crime) offense. Punishments for DUI/DWI crimes can be severe (for example, losing your driving privileges); if you have been accused of a DUI or DWI offense, it's best to see an attorney who specializes in this field. An experienced DUI attorney can often get the charges dropped or reduced, or may be able to negotiate lesser penalties depending on your circumstances and your criminal history.
