How the enhancement works
Section §346.65(2)(f) has two subparagraphs that operate differently depending on whether it’s a 1st offense or a subsequent one:
§346.65(2)(f)1: 1st offense with minor
For a 1st offense OWI with a passenger under 16, the statute imposes fines of $350-$1,100 and imprisonment of 5 days to 6 months. Those are 2nd-offense-level penalties. What would normally be a civil forfeiture becomes a criminal misdemeanor with mandatory jail.
§346.65(2)(f)2: 2nd and subsequent offenses with minor
For a 2nd or subsequent offense with a passenger under 16, the minimum and maximum fines and imprisonment are doubled, and the applicable license revocation period is also doubled. Doubling doesn’t automatically elevate the offense to the next tier, but it can push the maximum imprisonment above the 1-year misdemeanor threshold, which has felony implications for sentencing and record classification. §346.65(2)(f)2 also provides that any qualifying 3rd-or-higher offense with a minor passenger is treated as a felony with the place of imprisonment determined under §973.02.
| Your actual offense count | Penalty with minor passenger | Key consequence shift |
|---|---|---|
| 1st offense | $350-$1,100 fine; 5 days-6 months jail (§346.65(2)(f)1) | Civil forfeiture → criminal misdemeanor with mandatory jail |
| 2nd offense | Fines and imprisonment doubled (§346.65(2)(f)2) | Standard 5-day min jail doubled to 10 days; max doubled to 12 months |
| 3rd offense | Fines and imprisonment doubled (§346.65(2)(f)2) | 45-day min jail doubled to 90 days; max doubled to 2 years |
| 4th offense (felony) | Fines and imprisonment doubled (§346.65(2)(f)2) | Class H felony penalties doubled; exposure reaches higher felony ranges |
The consequences compound fast: A 1st OWI with a minor becomes a criminal misdemeanor. A 3rd with a minor has its 45-day jail minimum doubled to 90 days and its 1-year maximum doubled to 2 years. Those consequences rival a standard 4th-offense felony. The doubled license revocation alone can end many employment situations.
Do I need a lawyer if a child was in the car?
Yes. A minor passenger can turn the case from a standard first-offense OWI into a criminal misdemeanor with mandatory jail and a likely child-welfare track. The first questions are whether the child was under 16, whether the child was in the vehicle during the alleged operation, and whether the OWI itself can be challenged. Start with our first OWI lawyer-decision guide, then review this enhancement page closely.
CPS and family court consequences
An OWI arrest with a minor passenger often triggers a referral to Child Protective Services. This runs parallel to the criminal case and can result in:
- A CHIPS (Child in Need of Protection or Services) petition
- Temporary removal of the child from the home pending investigation
- Safety plans restricting unsupervised contact with the child
- In custody disputes, the arrest becomes evidence in family court proceedings
The criminal defense and the CPS response must be coordinated. Statements made to CPS workers can be used in the criminal case. We advise clients on both fronts simultaneously.
Defense strategies
Challenging the minor-passenger element
The state must prove that a person under 16 was in the vehicle at the time of the violation. Challenges include:
- Age verification: The state must prove the passenger was under 16, not just assert it. Birth certificates or testimony may be required.
- Timing: If the minor was not in the vehicle during the period of impaired driving (e.g., dropped off before the incident), the enhancement may not apply.
- “Motor vehicle” definition: Parked vehicles, vehicles on private property, and other edge cases can affect whether the enhancement element is met.
Standard OWI defenses apply
Every defense available at the underlying offense level remains available: suppression of the traffic stop, challenges to the breath or blood test, prior-offense audits, and “operating” element disputes. If the underlying OWI is dismissed, the minor-passenger enhancement falls with it.
Negotiating the enhancement away
In some jurisdictions, prosecutors may agree to dismiss the minor-passenger enhancement as part of a plea negotiation, particularly when the evidence on the enhancement element is weak. This drops the defendant back to the standard penalty tier, potentially the difference between a criminal misdemeanor and a civil forfeiture, or between doubled and standard jail exposure.
Protecting parental rights
For parents charged under §346.65(2)(f), the stakes extend far beyond the criminal case. We work with family law counsel when necessary to:
- Prevent temporary custody changes from becoming permanent
- Ensure CPS investigations are handled properly and do not generate self-incriminating evidence
- Document treatment compliance and sobriety for use in both criminal and family proceedings
- Coordinate criminal plea terms with family court requirements
Two fronts, one defense. An OWI with a minor triggers both criminal and family consequences. Call (262) 632-5000 for a free consultation that addresses both. We serve Racine, Kenosha, and Walworth counties.
