Chemical Testing & Refusal

What Happens With Chemical Testing in an Ohio OVI Case?

Chemical testing can become a major part of an Ohio OVI investigation. Depending on the circumstances, an officer may request a breath, blood, or urine test to determine the concentration of alcohol or certain drugs in a person’s system. A refusal can also create separate driver’s license consequences and become an important part of the OVI case.

This page explains the different types of chemical tests used in Ohio OVI cases, what happens when someone refuses testing, and how chemical-test evidence may be evaluated and challenged.
