Understanding OWI in Wisconsin: What You Need to Know

Operating While Intoxicated (OWI) in Wisconsin is a serious offense that can have lasting legal and financial consequences. Whether you are facing your first OWI charge or have prior offenses, understanding the law, potential penalties, and your legal rights is crucial. At Scott-Johnson & Smith LLP, we are committed to helping you navigate the complexities of OWI cases and protecting your rights.
What is OWI in Wisconsin?
In Wisconsin, OWI refers to operating a motor vehicle while under the influence of alcohol or drugs to a degree that renders you incapable of safely driving. This includes:
A Blood Alcohol Concentration (BAC) of 0.08% or higher for most drivers.
A BAC of 0.04% for commercial drivers.
A BAC of 0.02% for drivers under the age of 21 (Wisconsin’s Zero Tolerance Law).
Driving while impaired by controlled substances, prescription medications, or other intoxicants.
Penalties for OWI in Wisconsin
The penalties for an OWI conviction depend on the number of prior offenses and other aggravating factors. Here is a general overview:
First Offense (Non-Injury OWI)
Fine: $150 – $300 (plus surcharges)
License Suspension: 6 to 9 months
Ignition Interlock Device (IID) or Sobriety Program: Required if BAC is 0.15% or higher
No jail time, unless there are aggravating factors
Second Offense
Fine: $350 – $1,100 (plus surcharges)
License Suspension: 12 to 18 months
Jail Time: 5 days to 6 months
IID Requirement: Mandatory
Third Offense
Fine: $600 – $2,000 (plus surcharges)
License Suspension: 2 to 3 years
Jail Time: 45 days to 1 year
IID Requirement: Mandatory
For subsequent offenses, penalties become increasingly severe, including longer jail sentences, higher fines, and extended license revocations. If an OWI results in injury or death, the charges can escalate to felony status, leading to significant prison time and long-term consequences.
Defenses Against OWI Charges
A strong legal defense can make a significant difference in the outcome of an OWI case. Common defenses include:
Challenging the traffic stop – Was there a valid reason for law enforcement to stop your vehicle?
Questioning field sobriety tests – Were the tests conducted properly, and are they reliable?
Disputing BAC results – Were there errors in the breathalyzer or blood test procedures?
Medical conditions or external factors – Could medical conditions, diet, or other factors have influenced BAC readings?
What to Do If You Are Arrested for OWI
Remain Calm and Polite – Cooperate with law enforcement but remember your rights.
Exercise Your Right to Remain Silent – You are not obligated to answer incriminating questions without an attorney present.
Document Everything – Write down details of the arrest, including the officer’s conduct and testing procedures.
Contact an Attorney – Contact an experienced OWI defense lawyer immediately.
