OVI is specific to Ohio. Ohio’s DUI statute is in O.R.C. 4511.19 titled, “operating vehicle under the influence of alcohol or drugs—OVI.” In 2001 the Ohio legislature changed the definition of driving in the DUI statute to operating and modified the penalties.  DUI stands for “driving under the influence” and can include drugs as well as alcohol.  DWI, “driving while impaired,” is specific to driving while drunk from too much alcohol consumption.
