Following a recent trend in many other states, Michigan takes a hard line on driving under the influence of alcohol, illegal drugs, or Schedule 1 controlled substances - which can include some prescription medications. If you are over the legal limit of alcohol (0.08%) or if you have any amount of cocaine or a Schedule 1 controlled substance in your system, you may face a variety of penalties. This includes mandatory suspension of your driving privileges for at least 6 months - even for a first offense.
Driving While Under the Influence of an Illegal Drug, Schedule I Controlled Substance, or Prescription Medication in Michigan
In Michigan, a person will be convicted of a DUI if he/she operates a motor vehicle upon a highway or other place open to the general public while under the influence an illegal drug, schedule I controlled substance or a prescribed medication that prohibits driving upon ingestion. See Mich. Comp. Laws Ann. § 257.625.
