In Ohio, driving under the influence is officially called "operating a vehicle under the influence" or "OVI." As in other states, Ohio's OVI laws apply not only to alcohol but also to operating under the influence of drugs. But whereas in some states drug DUIs require proof of actual driver impairment, Ohio also has "per se" DUI drug OVI laws. With per se laws, the driver can be convicted of an OVI solely for having a certain concentration of drugs in his or her system.
Specifically, Ohio law defines a DUI OVI as operating a vehicle while "under the influence" of a controlled substance or with a blood concentration of at least:
When a drug OVI is based on the concentration of any of these controlled substances, the driver can be convicted without proof of actual impairment—blood test results showing a prohibited controlled substance concentration is sufficient.
Drivers who were using a controlled substance that was prescribed by a physician might have a defense to an OVI charge. To establish the defense, the driver must have a valid prescription for the controlled substance and have taken the controlled substance in accordance with a health professional's directions.
In practice, this defense doesn't often apply because a prescription for a controlled substance normally contains a warning against driving while taking the substance.
The consequences of an Ohio drugged driving conviction depend on the circumstances. But generally, an OVI carries the following possible penalties, which depend on how many prior convictions the driver has that occurred within the past ten years:
These are the normal ranges of penalties for drug OVI convictions. However, certain factors increase or decrease the penalties that the driver faces.
