Field Sobriety Tests

What Are Field Sobriety Tests?

Field sobriety tests are roadside exercises officers commonly use during an OVI investigation to look for signs they associate with impairment. How the tests were explained, demonstrated, administered, and scored—as well as the conditions under which they were performed—can become important issues in an OVI case.

This page explains the standardized field sobriety tests used in Ohio OVI investigations, what officers are looking for, and how the circumstances surrounding the testing may affect the evidence.

Why Some Ohio OVI Cases Quietly Get Better for the Defense Over Time
