Quick Answer
Ohio does not mandate IID for all OVI offenses. IID is at the court's discretion for most cases. However, judges commonly order IID for high-BAC offenses (0.17%+) and repeat offenders. Ohio gives judges broad authority to order IID for any OVI conviction.
IID Duration by Offense

|---|---|
| 1st Offense | Typically 6-12 months if court-ordered |
| 2nd Offense | 1 year (commonly ordered) |
| 3rd Offense | 1-3 years (commonly ordered) |
| 4th+ Offense | Court-determined (often 2+ years) |
BAC threshold: No mandatory threshold — court discretion. Commonly ordered for BAC 0.17%+ and repeat offenders.

Ohio-Specific Notes
Ohio uses the term OVI (Operating a Vehicle Impaired). Unlike most states listed here, Ohio does not have a blanket IID mandate. Instead, judges have discretion to order IID for any OVI case. In practice, most courts order IID for repeat offenders and high-BAC cases, but it is not guaranteed.
