In Michigan, OWI refers to operating a motor vehicle under the influence of alcohol or drugs. This includes not only illegal substances but also prescription and over-the-counter medications if they impair your driving. It’s illegal to drive with a BAC of 0.08% or more. However, if any amount of alcohol or drugs impairs your driving ability, you can still be charged with OWI. Additionally, Michigan law states that a BAC of 0.17% or higher is considered “super drunk,” which carries more severe penalties.
