A Michigan OWI with a blood alcohol content (BAC) reading of .17% or higher is not a standard drunk driving charge. It falls under Michigan’s Super Drunk law – a separate, enhanced charge that carries nearly double the penalties of a standard first-offense OWI.
Most people don’t know this distinction exists until they see it on a court document. By then, the stakes are already higher. This article explains what the Super Drunk law is, what it means for freedom and driving privileges, and – critically – what defenses are available.
| IMPORTANT: A Super Drunk OWI charge in Michigan is not the same as a standard OWI. The penalties are dramatically harsher. This is not a routine traffic matter. Call an OWI attorney today: (616) 915-6576. |
What Is Michigan’s Super Drunk Law?
Michigan’s Super Drunk law, codified under MCL 257.625(1)(c), was enacted in 2010 to create a more severe tier of punishment for drivers with a BAC of .17% or above – more than twice the standard legal limit of .08%.
The legislature’s reasoning: drivers at .17% BAC or higher are statistically much more dangerous, more likely to cause accidents, and more likely to be repeat offenders. The law treats them significantly differently – even on a first offense.
This is a Michigan-specific statute. Not every state has a separate enhanced tier at this threshold. Out-of-state drivers relying on prior DUI experience in other jurisdictions may have a false sense of what they’re facing.
Super Drunk vs. Standard OWI: A Side-by-Side Comparison
| Penalty | Standard OWI (BAC .08–.16) | Super Drunk OWI (BAC .17+) |
| Jail time | Up to 93 days | Up to 180 days |
| Fines | $100–$500 + costs | $200–$700 + costs |
| License suspension | 30 days, then 150 restricted | 45 days, then full 320 days restricted ONLY with IID |
| Ignition interlock (IID) | Possible | Mandatory for entire restriction period |
| Community service | Up to 360 hours | Up to 360 hours |
| Driving record points | 6 points | 6 points |
The Ignition Interlock Requirement – What It Really Means
Perhaps the most disruptive consequence of a Super Drunk conviction is the mandatory ignition interlock device (IID) requirement. Under Michigan law, a driver convicted of Super Drunk OWI may only drive during the restriction period with an IID installed on the vehicle.
The IID is essentially a built-in breathalyzer. Before the car will start, the driver must provide a clean breath sample. The device also requires rolling retests while driving. A failed retest is treated as a violation and is reported to the court.
The costs add up fast:
- IID installation: $75–$150 upfront
- Monthly monitoring fee: $60–$100 per month
- Calibration visits every 30–60 days
- Any violation restarts or extends the monitoring period

Can a Super Drunk OWI Be Challenged or Reduced?
Yes – and this is where experienced legal representation matters most. Even when a BAC registers at .17% or above, there are legitimate, powerful defenses available.
- Challenging the Breathalyzer Result
The Intoxilyzer 9000 – Michigan’s current breath test device – must be properly calibrated, maintained, and operated by a certified technician. If any of these conditions weren’t met, the result may be suppressed. Calibration logs and maintenance records should be reviewed in every case.
Michigan recently transitioned from the DataMaster DMT to the Intoxilyzer 9000. Cases involving the older device during the transition window may have additional grounds for challenge.

- Challenging the Traffic Stop
Every OWI case begins with a traffic stop. If the officer lacked reasonable suspicion to pull the driver over, all evidence gathered after that stop – including the BAC result – may be suppressed. An unconstitutional stop can end a Super Drunk case before it reaches trial.
- Physiological Factors That Affect BAC Readings
Certain medical conditions, medications, and even diet can affect breath test accuracy. Conditions like GERD (acid reflux), diabetes, or high-protein diets can sometimes cause falsely elevated breathalyzer readings. Forensic experts are often brought in when physiological challenges are relevant to a case.
- Negotiating a Reduction
Even when the evidence is strong, a skilled Grand Rapids OWI attorney can sometimes negotiate a reduction from Super Drunk OWI to standard OWI – removing the mandatory IID requirement and reducing the maximum jail exposure from 180 to 93 days. The difference in real-world impact is enormous.

Does a Super Drunk OWI Show Up on a Criminal Record?
Yes. An OWI conviction in Michigan – including Super Drunk – is a criminal conviction that appears on the defendant’s criminal record. It also appears on the driving record and is visible to employers, insurance companies, and licensing boards.
The good news: Michigan law allows for OWI expungement under certain conditions. A first-offense OWI can be expunged after five years when no other OWI convictions exist. However, the conviction will always remain on the driving record even after expungement.
