Michigan Super Drunk Driving | High BAC Laws, Penalties and Defense
Michigan's Super Drunk driving law imposes significantly harsher penalties on first-offense OWI defendants whose breath or blood test result is 0.17 grams percent or above. The consequences are substantially more severe than a standard first offense: up to 180 days in jail instead of 93, higher fines, and most consequentially a mandatory 45-day hard license suspension with no driving of any kind, followed by up to 320 days of restricted driving only in a vehicle equipped with an ignition interlock device. For most defendants, the license consequences are the most immediately disruptive element of the charge, and determining whether a charge reduction is possible to get the case out from under those mandatory sanctions is the first strategic objective of the defense.
Super Drunk cases are built almost entirely on breath test evidence. Unlike cases involving obvious impairment or accidents, the enhanced charge typically rests on a single number produced by a breath testing instrument. How that number was produced, and whether the testing process was scientifically reliable, often matters more than the number itself.
This fact cuts in both directions. A person with a prior OWI conviction within the past seven years who tests at 0.22 is charged with second-offense OWI, not super drunk driving, and second-offense OWI carries mandatory sentencing of either at least 5 days in jail or at least 30 days of community service, at the court's discretion, along with license revocation rather than suspension. Many people assume a higher BAC number always produces a worse legal outcome. In Michigan's tiered OWI system, which charge applies depends on the defendant's prior record, and that distinction determines the available defense strategies and sentencing options.
What are the Penalties for a High BAC Super Drunk Driving in Michigan?
Drivers convicted of super drunk high BAC face enhanced penalties. These include:
- Jail time - possible incarceration of up to 180 days in jail. This is nearly twice as long as a “traditional” or non-super drunk driving first offense, which is punishable by up to 93 days in jail.
- Fines and costs - fines are also higher. For a High BAC super drunk driving, the fine is $200.00-$700.00. Compared with a traditional first offense OWI in Michigan, which is punishable by a $100.00-$500.00 fine.
- Community service - you can also be ordered to complete up to 360 hours of community service.
- Driver license sanction - your driving privileges will be suspended by the State of Michigan for one full year. This year starts with “hard suspension” for the first 45 days. After that, a driver may engage in certain restricted driving activities for the following 320 days, but only if a Breath Alcohol Ignition Interlock Device (BAIID) is installed on all vehicles the offender might drive. If the person drives a car without a BAIID, then their vehicle may be immobilized if they are so convicted. Finally, a conviction will result in 6 points being added to the driving record. The ignition interlock requirements and the text of the governing statute are addressed on the firm’s dedicated BAIID page and in MCL 257.625k.
There are other penalties that can be ordered by the Judge. These include stricter conditions of bond and probation, a longer overall term of probation and more intensive alcohol treatment.
Why Super Drunk Cases Depend Heavily on Breath Testing
Most Super Drunk cases are built almost entirely on breath-test evidence. Unlike cases involving obvious impairment or crashes, the enhanced charge typically hinges on a single number produced by a breath-testing instrument.
Understanding breath testing in Michigan DUI cases requires more than looking at the printed ticket. Issues such as machine instability, improper administration, breathing technique, and environmental interference can materially affect reported BAC results, particularly at higher levels.
In many cases, the outcome turns on a close review of the Intoxilyzer 9000 breath test data, including the machine’s internal diagnostics and whether the testing process was scientifically reliable.
Why a High BAC Number Is Not Automatically Reliable
Many people assume that higher BAC results are more reliable. In reality, breath testing is sensitive to physiological and mechanical variables regardless of the reported number.
Scientific research has shown that breathing technique alone can produce materially different results in the same person. Longer or forced exhalations, often encouraged when a machine rejects samples, can inflate reported BAC levels.
For readers who want a deeper technical explanation of why breath-test numbers can vary, these issues are discussed in peer-reviewed legal and scientific literature.
Why a Higher BAC Can Make a Michigan Super Drunk Case More Defensible
Here is a fact that consistently surprises defendants after a super drunk arrest: the higher the reported BAC, the greater the scientific demands placed on the prosecution's case. A result of 0.09 is close enough to the legal limit that the officer's observations and the defendant's behavior carry most of the evidentiary weight. A result of 0.22 requires the prosecution to establish that the Intoxilyzer 9000 was properly calibrated, that the operator was currently certified, that the observation period was correctly conducted, and that the result is physiologically consistent with everything else the officer documented. When any one of those requirements is not met, the highest-seeming number in the case becomes its most vulnerable point.
Patrick Barone’s pre-medical biology training, combined with manufacturer-equivalent certification on Michigan’s evidentiary breath testing instruments and co-authorship of a February 2026 Michigan Bar Journal article on the Intoxilyzer 9000 transition, means the Barone Defense Firm reads breath test records not as legal documents to be challenged on procedural grounds but as a scientist who understands why the instrument produced the number it did and where the evidentiary gaps are. In jurisdictions where prosecutors maintain firm no-plea-bargain policies on high-BAC cases, the defense investigation is not a preliminary step before negotiation. It is the mechanism by which negotiation becomes possible.
Lead litigating attorney Ryan Ramsayer has done groundbreaking work identifying errors in COBRA data, the internal diagnostic records generated by the Intoxilyzer 9000, that have produced numerous case dismissals and no-alcohol plea reductions for the firm’s clients. He has presented this methodology at MIAOWI seminars, sharing the firm’s analytical approach with OWI defense attorneys across Michigan. No firm in the state has reviewed more of this data or developed more ways to challenge the result it reflects. Where the reported BAC is inconsistent with a defendant’s observable behavior at the time of the arrest, the alcohol tolerance argument prosecutors deploy to explain that inconsistency is refuted by published science.
Multiple Breath Attempts and Inflated Results
In some Super Drunk cases, individuals are required to blow repeatedly before a result is recorded. Multiple rejected samples are not meaningless. They can indicate that the machine struggled to obtain a stable reading.
Repeated forced attempts may also encourage breathing patterns known to elevate reported BAC results, particularly when officers instruct subjects to “keep blowing.”
Frequently Asked Questions About Super Drunk Driving in Michigan
If My BAC Was Over .17, Does That Automatically Mean I Will Be Convicted of Super Drunk Driving?
No. A BAC reading is evidence, not a conclusion. Super Drunk charges depend heavily on breath-test results, and those results are only as reliable as the testing process used to produce them. Issues with machine stability, administration, or breathing technique can affect reported numbers, even at higher BAC levels.
Are High BAC Breath Test Results More Reliable Than Lower Ones?
Not necessarily. Breath testing is sensitive to physiological and mechanical variables regardless of the reported number. Scientific research shows that breathing technique alone can materially affect results, and repeated or forced breath attempts may inflate reported BAC levels.
Can Breath Testing Problems Still Matter in Super Drunk Cases?
Yes. Because Super Drunk charges typically hinge on a single breath-test number, identifying problems with how that number was generated can be especially important. Machine diagnostics, internal data, and operator compliance all matter.
What if I Was Required to Blow Multiple Times Before the Machine Accepted a Result?
Multiple rejected samples are not meaningless. They may indicate that the breath-testing instrument struggled to obtain a stable reading. Repeated attempts can also encourage breathing patterns known to elevate reported results.
Does Super Drunk Driving Always Require an Ignition Interlock?
In most cases, yes. Michigan’s Super Drunk law includes mandatory alcohol monitoring requirements, including ignition interlock use. The exact consequences depend on the specific facts of the case and how it is resolved.
Why Is Early Review Important in Super Drunk Cases?
Breath-testing data and diagnostic records may be overwritten or purged. Early review allows for preservation and analysis of evidence that may not be apparent from the breath-test ticket alone.
Can a Super Drunk Charge Be Reduced to a Standard First-Offense OWI?
In some cases yes, and achieving that reduction is often the primary strategic objective because it removes the mandatory 45-day hard suspension and 320-day BAIID requirement. Whether a reduction is available depends on the jurisdiction, the prosecutor’s office policy, and the strength of the defense case. Some counties maintain firm no-plea-bargain policies on high-BAC cases. In those jurisdictions, a reduction requires identifying a specific legal or scientific vulnerability in the evidence that gives the prosecutor a reason to reconsider.
Is a Super Drunk Conviction Eligible for Expungement in Michigan?
A super drunk OWI conviction is treated as a first-offense OWI conviction for purposes of Michigan’s Clean Slate legislation and is potentially eligible for expungement after the applicable waiting period, provided the eligibility requirements are met, including no subsequent OWI convictions of any kind. Eligibility and the petition process should be discussed with an attorney.
How to Avoid the Enhanced Penalties of Super Drunk Driving
Other than avoiding the conviction, there is no way to avoid many of the more serious penalties. For example, you cannot avoid the one-year license sanction. This is because the Secretary of State imposes this suspension as soon as they learn from the Court that the conviction has occurred. After that there is no available “due process” meaning there is no opportunity to be heard as to why the one-year suspension should not be imposed.
The only way to avoid the enhanced penalties therefore is to engage an OWI defense attorney who knows the importance of zealously defending clients accused of this serious crime. Armed with a proper defense, some or all the enhanced penalties can be avoided.
Will My Super Drunk 0.17 BAC Case be Reduced?
As it relates to plea negotiations, some prosecuting attorneys have policies that will not allow a super drunk case to be reduced, meaning there is no plea bargaining. In these cases, if no motions are available or successful, the client must either plead guilty as charged or stand trial.
The decision of whether to go to trial is one that only a client can make after a thorough evaluation and examination of the case by their attorney. Our article entitled Should I Take my Drunk Driving Case to Trial or Just Plead Guilty will help you make this decision.
In some cases, if there is no plea bargain offered then a trial will make sense either because the client cannot endure the harsh penalties, or when a defense exists. For example, a High BAC OWI is based 100% on the breath or blood test.
If there is any reason to believe that the breath test is flawed, that it is inaccurate or unreliable, then a trial may make sense. There are many possible defenses to a High BAC OWI, and these should be discussed with your attorney.
Will I Go to Jail if I’m Convicted of High BAC Super Drunk Driving?
The answer to this question can only be determined after a person’s case and prior record have been evaluated. The court/judge before which the case is pending will also make a big difference. Winning motions, winning at trial, or engaging in meaningful plea negotiations can also be a factor in whether a person goes to jail, and for how long.

Additional Consequences of a Super Drunk Conviction in Michigan
Judges don't look very favorably upon drivers who are convicted of a super drunk offense in Michigan. For this reason, the penalties you're likely to receive may be more severe than if you're able to plead down to a normal DUI/OWI offense. The additional consequences of a super drunk conviction include:
- A longer probationary period
- Mandatory jail time of up to 6 months
- Needing to keep a BAIID on your vehicle for at least one year
- Court-ordered alcohol treatment programs for up to 1 year
Next Steps in a Michigan Super Drunk Case
Because Michigan’s “Super Drunk” law applies at a BAC of 0.17 or higher and carries enhanced penalties, early evaluation of the chemical test evidence is critical.
In many cases, the reported BAC is treated as conclusive. But high-BAC cases often depend entirely on breath-test reliability, testing conditions, and how the result was obtained.
At Barone Defense Firm, we review the underlying breath-test data, not just the printed number, to determine whether the evidence supports the charge.
