In the simplest terms, the offense known as operating a vehicle while impaired (OVI) occurs whenever someone is operating a vehicle under the influence of alcohol, a drug of abuse, or a combination of both, or at or over the limit. OVI used to be called “DUI” or “DWI”. It is a serious criminal offense.

There are several ways that someone can commit an OVI:

1. If a person operates a vehicle in Ohio and at the time of operation is under the influence of alcohol, a drug of abuse, or a combination of them
2. If a person operates a vehicle in Ohio and at the time of operation the person has a concentration of alcohol, certain controlled substances, or metabolites of certain controlled substances, in the person’s blood, breath or urine which is at or over the “legal limit”
3. If a person operates a vehicle in Ohio while under the influence of alcohol, a drug of abuse, or a combination of them and refuses to submit to a chemical test after being arrested and asked to submit to a test, and has a prior OVI in the past 20 years
4. If a person is under 21 years old, operates a vehicle in Ohio, and at the time of operation has a concentration of alcohol in the their blood, breath, or urine which is at or over the “under 21 legal limit”
