OVI stands for "Operating a Vehicle while Impaired" and is a term used in Ohio to describe drunk driving or driving under the influence of drugs. It is a broader category that includes alcohol intoxication and any impairment from illegal drugs, prescription drugs, or over-the-counter drugs. The term OVI replaced several other acronyms that were used in Ohio to describe impaired driving, including DUI (Driving Under the Influence), DWI (Driving While Intoxicated), and OMVI (Operating a Motor Vehicle Impaired) . While these terms may have subtle differences in other states, in Ohio, they all target the same types of behavior.
