The offense of driving under the influence of intoxicants (DUII) can be referred to by several names. Some states define the crime differently. Some states refer to the crime as DUI, for Driving Under the Influence. Some states use the name DUII, for Driving Under the Influence of Intoxicants. And some states call the offense DWI, for Driving While Intoxicated.
In practicality, these all are referring to the same crime. Technically, in Oregon, the crime is Driving Under the Influence of Intoxicants, shortened as DUII.
