DUI – Driving Under the Influence
OWI – Operating While Impaired
DWI – Driving While Intoxicated

The biggest difference between DUI and DWI is only in what the letters stand for. In some states, the drunk driving laws differentiate between a DUI and a DWI, where the DUI is a lesser charge. In these states, a DUI usually signifies a lesser degree of intoxication, which is determined by a person’s blood alcohol level at the time of arrest. Other terms beside these two are also employed, such as OUI and OWI, replacing the D for driving with an O for operating.

Other Answer(5) :


I think it depends on which state you live in as to how its classified.

DUI = Driving Under the Influence
OWI = Operating While Impaired
DWI = Driving While Impaired
OUIL = Operating Under the Influence of Intoxicating Liquor


There is none. It's not even a state by state thing, because one state could call it all or none (since there's other abbr. for DUI) at the same time.


DUI can mean driving while drunk, high, or impaired by any altering substance.


DUI – Drivind under the influence
DWI – Driving while intoxicated

i don't know what OWI means

i think the difference is basically in the phrasing they all pretty much mean the same thing


They are just different abbreviations for the same thing. But there are important differences in drunk driving laws. Some examples:
Does it cover "vehicles" or "motor vehicles" – vehicles is much more broad and can cover bicycles, Amish buggies (it happens), etc…
Does it have a specific intoxicant or level of intoxication (i.e. driving with a BAC above .08) or does it just say impaired/intoxicated? – the law may cover just alcohol, just illegal drugs, or anything that intoxicates a person – including validly prescribed drugs.
Does it have a consequence requirement – i.e. causing danger to self, to others? This is important because if you were pulled over for something not inherently dangerous (busted light) then the state still has to prove something other than just drunk/impaired (but sometimes the sheer level of intoxication is considered proof enough).
