Chemical Testing & Refusal

What Happens With Chemical Testing in an Ohio OVI Case?

Chemical testing can become one of the most important parts of an Ohio OVI case. After an OVI arrest, an officer may request a breath, blood, urine, or oral-fluid test to determine the concentration of alcohol or certain drugs in a person’s system. The decision to submit to or refuse testing can also have immediate consequences for a driver’s license.

This page explains the different types of chemical tests used in Ohio OVI cases, what can happen after a refusal, and how the collection, handling, and reliability of chemical-test evidence may become important to the defense.
