In Michigan, you are considered “super drunk” if you drive with a blood alcohol content of 0.17 or higher, which is more than double the standard 0.08 legal limit.1State of Michigan. Impaired Driving Law Hitting that number puts you into a separate, harsher penalty category that applies even on a first offense, with no prior drunk driving record required.
What the Super Drunk Law Actually Says
The official name is Operating With a High BAC. It lives in MCL 257.625(1)(c), which defines the offense as operating a vehicle with an alcohol content of 0.17 grams or more per 100 milliliters of blood, per 210 liters of breath, or per 67 milliliters of urine.2Michigan Legislature. MCL 257-625 It is not an enhancement bolted onto a standard OWI. It is a distinct charge inside the same statute, with its own penalty structure.
Your driving history does not change whether the charge applies. If a chemical test puts you at 0.17 or above, you are facing the high BAC offense rather than a standard 0.08 OWI, even if it is the first time you have ever been stopped.
Penalties for a First Offense
A first-time high BAC conviction carries penalties that resemble what many states reserve for repeat offenders:
- Up to 180 days in jail, compared with 93 days for a standard first-offense OWI.1State of Michigan. Impaired Driving Law
- Fines of $200 to $700, before court costs or other fees.2Michigan Legislature. MCL 257-625
- Up to 360 hours of community service.1State of Michigan. Impaired Driving Law
- Mandatory completion of a court-ordered alcohol treatment program.
The statutory fine is only part of what you pay. Add court costs, probation supervision fees, and treatment program fees, and the real out-of-pocket number climbs well above the headline figure.
A conviction also adds 6 points to your Michigan driving record, which stays on your record for two years.
License Suspension and the Ignition Interlock
A high BAC conviction triggers a one-year license suspension that runs in two phases.1State of Michigan. Impaired Driving Law The first 45 days are a hard suspension. You cannot drive at all during that window, and there are no exceptions for work, medical appointments, or family needs.
For the remaining 320 days you can apply for a restricted license, but only if you install a Breath Alcohol Ignition Interlock Device, commonly called a BAIID, on your vehicle. The BAIID requires a clean breath sample before the engine starts and prompts random retests while you drive. You pay for installation, the monthly lease, and all calibration and maintenance. Installation typically runs several hundred dollars, with monthly costs in the $50 to $150 range. The device stays on for the full restricted period, and tampering with it or failing a retest creates new legal problems on top of what you are already dealing with.1State of Michigan.

What a Conviction Does to the Next Seven Years
Michigan uses a seven-year lookback window for drunk driving offenses.2Michigan Legislature. MCL 257-625 Any alcohol-related driving arrest within seven years of your high BAC conviction is prosecuted as a second offense, and the gap between first and second penalties is large:
- 5 days to 1 year in jail, with a mandatory minimum this time.
- Fines of $200 to $1,000.
- 30 to 90 days of community service.
- License revocation of at least one year, with no restricted driving during the revocation.
- Mandatory vehicle immobilization of 90 to 180 days.3Michigan Legislature. MCL 257-904d
A third drunk driving offense at any point in your life, with no time limit, is a felony punishable by up to five years in prison. The first high BAC conviction is where that clock starts running.
If You Hold a CDL
A super drunk conviction is especially damaging if you hold a commercial driver license, and it does not matter whether you were driving a personal vehicle at the time. Under 49 CFR 383.51, a first alcohol-related conviction disqualifies you from operating a commercial vehicle for one year.4eCFR. 49 CFR 383.51 Disqualification of Drivers A second conviction is a lifetime CDL disqualification.
Michigan does not grant restricted commercial driving privileges during a disqualification. If you drive for a living, that single consequence often outweighs the jail time and fines combined. Drivers who petition for reinstatement after a lifetime ban must wait at least 10 years, and reinstatement is not guaranteed.
Insurance and the Real Price Tag
Michigan requires an SR-22 certificate of financial responsibility for at least three years after an alcohol-related driving conviction. The SR-22 is not a separate policy. It is a form your insurer files with the state confirming you carry at least the minimum required coverage, and it flags you as a high-risk driver.
After a high BAC conviction, auto premiums commonly climb 60% or more, and some drivers see their rates double or triple. Your current insurer may decline to renew, pushing you toward high-risk insurers that charge substantially more. Elevated rates typically outlast the SR-22 period by several years.
When you total the fines, court costs, BAIID expenses, higher premiums, treatment program costs, and lost wages from jail time or license restrictions, a first-time high BAC conviction routinely runs $10,000 or more over the first few years. Defense counsel is on top of that, usually $2,000 to $15,000 for an aggravated DUI case depending on whether the case goes to trial.
Travel to Canada
A high BAC conviction can block entry into Canada. Canadian immigration law treats impaired driving as a serious criminal offense, and a single DUI can make you inadmissible at the border.5U.S. Customs and Border Protection. Entering Canada and the United States With DUI Offenses Whether you are allowed in depends on the specific offense, how long ago it happened, and your conduct since.
You may still be able to enter by showing you have been rehabilitated, by applying for and receiving formal rehabilitation approval, or by obtaining a temporary resident permit. None of those routes is automatic. Each one involves paperwork, fees, and waiting periods, and people who cross the border regularly for work or family are often caught off guard by the restriction.
Can the Charge Be Reduced?
Plea bargaining in Michigan high BAC cases is possible and happens more often than people expect. Prosecutors sometimes agree to reduce the charge to a standard OWI or to Operating While Visibly Impaired, known as OWVI, which carries lighter penalties. A reduction to OWVI avoids the mandatory BAIID requirement and the elevated fine range, and it puts fewer points on your driving record.
Whether a reduction is on the table depends on the BAC reading itself, the circumstances of the stop, whether anyone was injured, and the strength of the prosecution’s evidence. If your BAC was well above 0.17 or if the stop involved an accident, the odds of a favorable plea shrink. Plea practice also varies widely by county and prosecutor, which is where experienced Michigan DUI counsel can make a measurable difference in the outcome.
