By way of introduction, Michigan statutory law calls drunk driving “operating while intoxicated” (OWI). Drinking and driving is not against the law. To violate Michigan’s OWI law a person must be driving under the influence of drugs or alcohol. If you operate a vehicle after drinking enough alcohol to become intoxicated, then you’ve committed the offense of drunk driving. In other words, DUI and OWI are essentially the same thing.
Michigan law provides that for every person convicted of drunk driving must be subjected to substance use evaluation prior to sentencing. More specifically, Michigan Compiled Laws sec. 257.625b indicates that such individuals must undergo a screening and assessment to determine if the person would benefit from “rehabilitative services,” which may include such things as alcohol or drug education or treatment programs.
