Michigan law does not use “aggravated OWI” as a separate offense label. Instead, MCL 257.625 lists several OWI-related offenses and penalty enhancements that may apply depending on the facts of the case. These may include a high BAC, a prior conviction, a minor passenger in the vehicle, or a crash that causes serious injury or death. A drug-related OWI may also be charged when a driver has any amount of certain controlled substances in their system under Michigan’s “any amount” law.
Michigan OWI/DUI attorney Paul J. Tafelski has been representing people accused of drunk driving offenses, from first-time stops to felony cases. At Michigan Defense Law, our team defends drivers throughout Oakland County against OWI charges and the aggravating circumstances that raise the stakes.

I was arrested for drunk driving and possession of a controlled substance (Vicodin). Paul worked hard on the case and kept the felony off my record and got the drunk driving case reduced so that I kept my driver’s license and my job. He really cared about helping me.
In Michigan, there is no separate charge called “Aggravated DUI/OWI”. However, many factors that can cause a normal OWI to become “aggravated” by circumstances surrounding the case. The controlling statute, MCL 257.625, sets out the offense and the specific facts that increase its severity.
Michigan drunk driving charges fall into tiers, and the tier depends on what the prosecutor can prove. OWVI, or Operating While Visibly Impaired, is the lowest tier and is based on observable impairment rather than a numerical BAC threshold. Standard OWI can be based on impairment evidence or a BAC of 0.08% or higher for drivers aged 21 or older. Michigan also has separate rules for drivers under 21 and for certain controlled substances.
Each tier requires the prosecution to prove different elements, and those differences often create room for the defense to change the outcome. The table below compares the three tiers at a glance.
| Charge Tier | Basis for Charge | Classification |
|---|---|---|
| OWVI (Operating While Visibly Impaired) | Visible impairment from alcohol, controlled substances, other intoxicating substances, or a combination; no set BAC threshold | Misdemeanor |
| Standard OWI | Impairment evidence, BAC of 0.08% or higher for drivers age 21 or older, or certain controlled-substance violations | Misdemeanor for first or second offense |
| High BAC OWI | BAC of 0.17% or higher | Misdemeanor for a first High BAC offense; felony may apply if other felony-triggering facts are present |
| Repeat OWI | Prior qualifying OWI-related convictions | Second offense within seven years is generally a misdemeanor; third qualifying offense may be a felony |
| OWI with Minor Passenger | OWI with a passenger under 16 | Enhanced penalties; felony may apply with qualifying prior convictions |
| OWI Causing Serious Impairment or Death | Operation of a vehicle while intoxicated causes serious impairment of a body function or death | Felony |
Key Takeaway: Michigan structures drunk driving offenses into distinct tiers, ranging from OWVI to felony charges, based on BAC levels, impairment evidence, and aggravating factors. Each tier requires the prosecution to prove specific legal elements; identifying the exact basis for the charge is critical when evaluating defense options.
Every OWI tier relies on specific legal thresholds and evidence. We can evaluate the prosecution’s case to determine whether the charges are properly categorized and explore available defense strategies. Call (248) 451-2200 to schedule a consultation.
Certain facts can increase OWI penalties or lead to related charges. The most important distinction is whether the fact is covered under MCL 257.625 or a separate offense. The following sections explain the main penalty-enhancing facts under Michigan OWI law.
Repeat offenses can lead to progressively harsher penalties under Michigan OWI law. In Michigan, a third OWI offense within a lifetime is treated as a felony, regardless of the specific circumstances of the individual cases.
When an individual is charged with OWI while a minor is in the vehicle, the penalties are more severe because of the increased responsibility to protect minors from harm. Having an occupant aged 16 or under in the vehicle can lead to felony charges, especially if the driver has a qualifying prior conviction. If the minor or another person is seriously injured, separate injury-related OWI provisions may apply.
Michigan law imposes increased penalties for BAC levels significantly above the legal limit of 0.08%. A BAC of 0.17% or higher can lead to Michigan’s High BAC OWI penalties, often called ‘Super Drunk’ penalties.
If police allege unlawful drug possession during an OWI stop, that may lead to a separate controlled-substance charge. Michigan’s ‘any amount’ law (MSP Legal Update No. 96) prohibits driving with any measurable amount of a Schedule 1 controlled substance or cocaine in the body. Under that rule, a driver can face an OWI even without proof of visible impairment.
Key Takeaway: An OWI charge in Oakland County can carry higher penalties when the case involves prior OWI convictions, a passenger under 16, a BAC of 0.17% or higher, or controlled substances covered by Michigan’s “any amount” law. Some facts directly enhance the OWI charge under MCL 257.625, while others may lead to separate criminal charges.
Allegations involving high BAC levels, minor passengers, or Schedule 1 substances require careful legal analysis to ensure the prosecution’s charges are accurate and justified.

I wanted to say thank you for representing me this week. I could not be happier with the outcome. I truly realize how significant the impact of my situation is going to be the rest of my life. People make mistakes but people do change. You were a great supporter, open, candid and very honest. I felt like you really cared about the outcome of my case. I will gladly pass your name along to anyone I know who is seeking legal assistance for a DUI.
A BAC of 0.17% or higher can result in a “Super Drunk” charge under MCL 257.625, which carries penalties beyond a standard first-offense OWI. In addition to higher fines and a possible jail sentence of up to 180 days, the law may also require longer-term monitoring, treatment, or compliance measures.
For a High BAC conviction, a driver faces the following penalties and consequences:
Because the interlock and treatment mandates continue long after any jail term ends, a High BAC result can affect daily life for months. Challenging the reliability of the 0.17% reading is often central to defending these cases.
Key Takeaway: A BAC of 0.17% or higher triggers “Super Drunk” penalties in Michigan, including up to 180 days in jail, a mandatory alcohol treatment program, and ignition interlock use during restricted driving.
Challenging the validity and reliability of a high BAC reading can significantly alter the classification and penalties of your charge.

When an OWI causes serious impairment of a body function to another person, it is classified as a felony. The offense is punishable by up to five years in prison, a fine of $1,000 to $5,000, or both. This charge reflects Michigan’s strict stance on penalizing impaired driving that results in substantial harm to others.
If an OWI causes another person’s death, the charge can carry more severe felony penalties. In such cases, the felony charge carries a potential prison term of up to 15 years and fines range from $2,500 to $10,000.
In injury and death cases, the prosecution must prove that the driver’s conduct caused the harm. That causation link is often disputed through accident reconstruction and medical testimony, which can affect whether the felony charge holds.
A prior conviction can affect how a new OWI-related case is evaluated, even when the new charge is not filed as a felony. In Michigan, repeat offender penalties depend on the type and timing of prior convictions.
A second qualifying OWI-related conviction within seven years can result in second-offense penalties under MCL 257.625. These penalties may include a fine of $200 to $1,000, five days to one year in jail, 30 to 90 days of community service, or both jail and community service. License revocation and vehicle-related sanctions may also apply. Ignition interlock requirements may apply in specific restricted-license or probation contexts.
Michigan law treats some repeat OWI-related offenses more seriously. A third offense involving any combination of OWI and OWVI convictions may be charged as a felony OWI. This charge can carry mandatory jail time and a possible prison sentence of up to five years. Michigan also uses a lifetime lookback for certain repeat-offense enhancements. For example, an OWI charge after two or more prior convictions can be treated as a felony regardless of how much time has passed.
A prior OWVI conviction can also count as a prior conviction for enhancement purposes. Because of that, reducing a current charge to OWVI may lower the immediate charge or penalty exposure, but it does not remove the effect of prior convictions in future OWI-related cases.
Key Takeaway: A prior OWI or OWVI conviction can affect how a new Michigan drunk driving case is charged and penalized. A second qualifying offense within seven years can trigger enhanced penalties, while a third qualifying offense may be charged as a felony under Michigan’s lifetime lookback rules.
An experienced Michigan OWI/DWI attorney can audit the legal validity of prior convictions and challenge the state’s basis for enhancement. Contact us at (248) 451-2200 to schedule your confidential case strategy session.
A conviction for an OWI offense with enhanced penalties carries long-term consequences. Driving privileges are suspended or revoked depending on the BAC level and prior convictions. A standard first-offense OWI brings a 180-day license suspension, which includes a mandatory 30-day hard suspension followed by 150 days of restricted driving. A conviction also adds six points to the Michigan driver’s license.
For repeat offenses or revocations, restoring driving privileges may require an administrative hearing. For first-offense suspensions, the process may differ depending on the conviction and restriction period. Beyond the license, an OWI conviction can create a criminal record. Some first-offense OWI convictions may be eligible to be set aside, but repeat offenses and traffic offenses causing injury or death may be treated differently.
Key Takeaway: OWI convictions involving enhanced penalties can carry both criminal penalties and long-term consequences, including license suspension or revocation, six license points, and criminal record and repeat offender consequences.
Defending against aggravated OWI charges involves a strategy tailored to the specifics of each case. Effective defenses focus on the legality of the traffic stop, the accuracy of BAC results, and the causation behind any injury claim.
The validity of the initial traffic stop and subsequent arrest are common focal points in OWI defense. Your attorney can argue that the traffic stop lacked reasonable suspicion or that the arrest lacked probable cause. If evidence was obtained unlawfully, a court may suppress that evidence. Suppression can weaken the prosecution’s case and may affect negotiations or trial strategy.
Defense strategies can also include questioning the calibration and maintenance records of the evidential breath-testing instrument used, or the certification and conduct of the officer who administered the test. Other defenses may involve medical or dietary factors that could falsely elevate a reading, or timing issues suggesting the BAC rose between driving and testing.
In cases where an aggravated OWI charge is based on causing serious injury, a defense could focus on disputing the direct causation between the defendant’s actions and the injury. This might involve a detailed accident reconstruction or medical testimony showing that other factors contributed to or primarily caused the injuries.
Key Takeaway: Defending against aggravated OWI charges requires examining every stage of the prosecution’s case, from challenging the legal basis for the initial traffic stop to auditing breathalyzer accuracy and disputing the causes of the injury. Successfully challenging these elements can lead to evidence suppression, charge reductions, or case dismissals.
Successfully contesting an aggravated OWI requires a thorough review of police protocol, medical facts, and forensic testing methods. To learn how these defense strategies apply to your situation, call (248) 451-2200 to speak with a Michigan OWI/DWI attorney today.
A reduction from OWI to OWVI may be possible depending on the evidence, the prosecutor’s position, local court practices, and the facts of the case. The differences between OWI and OWVI can show why a reduction may matter, since OWVI is based on visible impairment rather than a BAC-based standard.
Pretrial motions may also affect the outcome of the case. For example, a defense attorney may challenge whether the traffic stop was lawful, the BAC evidence is reliable, or discovery issues affect the prosecution’s ability to prove the charge. If these challenges are successful, they may lead to the exclusion of evidence, a negotiated resolution, or, in some cases, dismissal.

No. Michigan law under MCL 257.625 does not create a separate crime called aggravated OWI. Instead, factors such as a high BAC, a prior conviction, a minor passenger, or an injury crash increase the severity of a standard OWI.
A BAC of 0.17% or higher can lead to a High BAC or “Super Drunk” charge. This tier carries up to 180 days in jail, a longer license suspension, a mandatory alcohol treatment program, and ignition interlock requirements.
An OWI becomes a felony when it is a third qualifying offense, when it causes serious impairment or death, or when an OWI with an occupant under 16 occurs with a qualifying prior conviction. Firearm allegations may create separate charges, but they should not be described as making the OWI itself a felony unless a specific statute supports that claim.
A second offense within seven years can bring a fine of $200 to $1,000, jail of five days to one year, 30 to 90 days of community service, and possible license revocation. Ignition interlock may apply in specific restricted-license or probation contexts.
Yes. Michigan’s “any amount” law prohibits driving with any measurable amount of a Schedule 1 substance or cocaine. A driver can face an OWI under this rule even without proof of visible impairment.
A reduction from OWI to OWVI may be possible depending on the facts of the case, the available evidence, the person’s prior record, and the prosecutor’s position. For a first-time offender, an OWVI conviction generally carries less severe licensing consequences than an OWI conviction.
An attorney can challenge the legality of the traffic stop, question the calibration and administration of the BAC test, and dispute causation in injury cases. Procedural errors may support suppression motions, negotiations for reduced charges, or, in some cases, dismissal.
