What is the difference between a DUI and OWI?

Driving Under the Influence (or DUI) is the commonly understood term for drunk driving. However, under Michigan law, it is called “Operating While Intoxicated” or OWI. The terms are used interchangeably, and it is important to understand the legal limit (.08 BAC) and the consequences of going over the limit in the context of being charged with an OWI.
