Indiana calls its impaired driving offense "Operating While Intoxicated" (OWI) — not DUI as most states use. The distinction reflects Indiana's broader statutory language: "operating" a vehicle (which can include non-moving scenarios in certain factual contexts) "while intoxicated" by alcohol or controlled substances under I.C. § 9-30-5-1 and § 9-30-5-2. Indiana's OWI law has two per se thresholds: .08% BAC for standard drivers; .04% for commercial vehicle operators; .02% for operators under 21. Indiana also has a Schedule I or II controlled substance per se provision — any amount of a Schedule I substance (including marijuana) or Schedule II substance (cocaine, methamphetamine) in the blood while operating creates a per se OWI regardless of observable impairment.
Indiana's OWI law operates in a state without the dry-county complexity of Tennessee — Indiana has uniform alcohol retail access across the state (counties cannot restrict alcohol sales through local option, unlike Tennessee's significant dry-county infrastructure). This creates a statewide entertainment drinking culture — Indianapolis's Fountain Square, Mass Ave, and Broad Ripple entertainment districts; South Bend's downtown bars near Notre Dame; Bloomington's college-town bar scene near Indiana University — without the wet/dry geographic discontinuities of Tennessee. Indiana Pacers games, Indianapolis Colts games at Lucas Oil Stadium, Indiana Fever games, and the Indianapolis Motor Speedway's multiple major events (Indianapolis 500, Brickyard 400) generate concentrated OWI arrest patterns during event seasons.
