What does OWI stand for? On a police report or a court record it means operating while intoxicated, the name some states use for driving, or controlling, a vehicle while impaired by alcohol or drugs. It covers the same kind of offense that other states call DUI or DWI.
Iowa, Michigan, Wisconsin and Indiana are among the states that use the OWI label. The word "operating" is chosen on purpose: it can reach more than just driving down the road, depending on the state's law.

What does OWI stand for on a court record?
Each letter stands for one part of the offense:
- O, operating: being in control of a motor vehicle. In some states this can include sitting behind the wheel with the engine running.
- W, while: at the same time as
- I, intoxicated: impaired by alcohol, drugs or both, or above the legal blood alcohol limit
Most states set the limit for drivers age 21 and over at a BAC of 0.08 percent, with lower limits for commercial drivers and drivers under 21. A person can also be charged when a lower reading or a drug clearly affects their driving.
OWI, DUI, DWI and OVI side by side
States pick their own names for impaired driving, so the letters vary across the map.
| Letters | Stands for | Where you might see it |
|---|---|---|
| OWI | Operating while intoxicated | Iowa, Michigan, Wisconsin, Indiana |
| DUI | Driving under the influence | Many states, and the most common term nationwide |
| DWI | Driving while intoxicated or impaired | Texas, New York and others |
| OVI | Operating a vehicle impaired | Ohio |
| OUI | Operating under the influence | Maine, Massachusetts and a few others |
Some states use two of these terms for different levels of the offense. The label on the paperwork tells you which law applies, but the penalties come from that state's rules, not from the letters themselves.
Where the letters appear
People usually look up OWI after seeing it on an official document.
On a court docket: "Count 1: OWI, first offense." This means the person is charged with operating while intoxicated, and the record shows no earlier conviction for it.
- Driver's license notices: a suspension letter may cite an OWI arrest or a refused breath test.
- Background checks: an OWI conviction can appear on criminal history reports.
- Insurance forms: applications may ask whether a driver has an OWI, DUI or similar record.
- News reports: local stories often use the state's own term.
An older meaning: Office of War Information
In history books, OWI means the Office of War Information, a US government agency created during World War II. It handled news releases, posters, radio programs and films about the war effort at home and abroad, and it closed soon after the war ended. If the text is about the 1940s, posters or wartime radio, this is the meaning. Find more agency names on the government acronyms page.
Pronouncing and spelling OWI
Say the three letters: "O W I." Write them in capitals without periods. Spoken, O sounds like "oh," so pick "an" over "a": "He was arrested for an OWI."
- "Her license was suspended after the OWI arrest."
- "The sheriff's office set up OWI checkpoints for the holiday weekend."
- "A second OWI usually carries tougher penalties than a first."
- "The defense attorney asked for the breath test records in the OWI case."
