In Wisconsin, drinking and driving is known as "operating a vehicle while intoxicated" or OWI. OWI laws prohibit operating any vehicle (car, snowmobile, boat, etc) while drunk, which is usually determined by blood alcohol level.
The BAC limit in Wisconsin at which no other evidence is required to show the driver was intoxicated for an OWI conviction is .08%. That's the "per se" BAC limit. This is called a Prohibited Alcohol Concentration (PAC) in Wisconsin. If you get an OWI, you will most likely get a second citation for a PAC.
You can still get an OWI with a BAC under .08 BAC, if the prosecutor can show how poorly you did in the field sobriety tests, such as standing on one leg or following an object with your eyes. Also, for anyone under 21, the legal drinking age in Wisconsin, there's a "zero tolerance law." The BAC limit for an underage driver is 0.02%. Drinking and driving at all while underage can get you an OWI-like charge (Absolute Sobriety ticket) even if you feel sober.
Wisconsin takes drinking and driving seriously. The OWI laws have criminal penalties that vary base on the number of prior offenses, BAC, and whether children were in the car. Each OWI offense has an OWI fee of $435. Approximately half of this surcharge goes to cover community programs to provide alcoholism and drug abuse services.
The following chart shows the general criminal penalties for OWIs in Wisconsin.
 | 1st OWI | 2nd OWI | 3rd OWI | 4th OWI | 5th-6th OWI | 7-9th OWI | 10th+ OWI |
Fine | $150-300 | $350-1,100 | $600-2,000 | $600-2,000 | $600-10,000 | Up to $25,000 | Up to $25,000 |
Jail | None | 5 days to 6 months | 45 days to 1 year | 60 days to 1 year | 6 months to 6 years | 3-10 years in prison | 4 to 12.5 years in prison |
License Revocation | 6-9 months | 12-18 months | 2-3 years | 2-3 years | 2-3 years | 2-3 years | 2-3 years |
IID | No | 12-18 months | 1-3 years | 1-3 years | 1-3 years | 1-3 years | 1-3 years |
Notes | If BAC over .15 IID required | Prior OWI within 10 years | Â | No OWI in past 5 years | Class G Felony | Class F Felony |
Most OWI offenses involve at least the short-term use of an Ignition Interlock Device (IID). This vehicle attachment requires you to blow into it to start your vehicle to prove you haven't been drinking before driving. Absolute sobriety is required to start the car in most cases. IIDs are not cheap to install and monitor.
Also, higher BAC concentrations increase the minimum and maximum fines. For a BAC of 0.17 to 0.199, the fines are doubled, for 0.20 to 0.249 the fines are tripled, and for 0.25 BAC or above the fines are quadrupled.
Wisconsin has a "Safe Streets" option for some OWI offenders to go to treatment for a reduced jail sentence. For a second time offender this cuts jail time to 5-7 days and for a third time offender, it's reduced to 14 days to 1 year. Four time OWI offenders can participate in Safe Streets as well for 29 days to 1 year in jail, if not in past five years.
If you have a child under 16 in your car when you drink and drive, the penalties are increased.
The fine for a first-time offender is $350-1,100 with minimum jail of 5 days, and with a license revocation from 12 to 18 months. For a second offense, the fine is $700-2,200 and jail for 10 days to 12 months. The license revocation can be for 2-3 years. For a third offense when a child is in the car, it's a $1,200-4,000 fine, jail for 90 days to 2 years, a revocation and IID for 4-6 years (once out of jail). For a fourth offense, it's the same, with 120 days in jail minimum with no OWIs in the past 5 years or 1-year minimum jail sentence for at least one prior OWI in the past 5 years.
Penalties continue to increase for subsequent OWIs.
If your license is revoked for an OWI, you can still get to work using an "occupational license." This is a restricted license that can be used no more than 12 hours a day and 60 hours per week to go to places such as work or church. For your first OWI, there is no waiting to period to get the occupational license. However, for a second or subsequent OWI or PAC conviction, you can't apply until 45 days into your revocation period.
Professional drivers are held to a higher standard. If you operate a commercial vehicle, the BAC limit is 0.04. You also canât drink within four hours before commercial driving.
Wisconsin has an "implied consent" law. This means, if you're driving, you agree to take a drug or alcohol test if thereâs reason to think you're driving under the influence. Refusing to take a test is a one-year license revocation and one year IID. If it's your second offense within 10 years, it's a two-year license revocation and 1-2 year IID use. If a third offense, it's a three-year license revocation and 1-3 years of having an IID.
Additional factors increase your license revocation for refusing a chemical test. If you have a child in the law, the max revocation and IID is two years for a first offense, four years for a second offense, and six years for a third offense. Also, for a first test refusal, you can't get the occupational license for 30 days, for a second refusal 90 days, and for a third refusal 120 days.
If you're facing a DUI charge in Wisconsin, you should quickly contact an experienced Wisconsin DUI attorney or your public defender. Working with an experienced lawyer should help you get back to driving as soon as possible.
