14 days-Day DMV Hearing Deadline

In Michigan, you have 14 days days from your arrest to request an administrative DMV hearing. Miss this deadline and your license suspension goes into effect automatically — even if the criminal case is later dismissed.

First Offense Penalties in Michigan

Jail TimeUp to 93 days (up to 180 days if BAC 0.17+)
Fines$100 – $500 ($200 – $700 if BAC 0.17+)
License Suspension30-day suspension + 150-day restriction
Ignition InterlockRequired for 1 year if BAC 0.17+

Implied Consent & Test Refusal

Like all 50 states, Michigan has an implied consent law — by driving on Michigan roads, you've already agreed to submit to a chemical test (breath, blood, or urine) if an officer has probable cause to believe you're impaired.

Refusal Penalty

1-year license suspension + 6 points on driving record

Michigan-Specific Detail

Michigan's 'Super Drunk Law' (BAC 0.17+) nearly doubles the penalties for first-offense DUI. Michigan also uses a lifetime lookback for prior offenses.
