That answer matters because many drivers believe refusal itself is illegal or guarantees an arrest. In practice, the decision to perform or refuse field sobriety tests often becomes a central issue in how an OVI case develops. Can You Refuse Field Sobriety Tests in Ohi

Field sobriety tests are defended on the ground that they are standardized. Officers invoke training. Prosecutors invoke the manual. The promise is that the test being described is the test that was validated. That promise often fails. In Ohio OVI investigations , officers routinely rely on techniques the manual never endorses. When asked to justify those techniques, the response is not science or training. It is silence. The absence of authority matters, especially when the

Field sobriety tests are repeatedly described as standardized. Officers testify that they are trained to follow a manual, taught to administer tests the same way every time, and expected to apply uniform criteria. That description often collapses under scrutiny. In Ohio OVI investigations , officers frequently add steps that do not appear anywhere in the NHTSA manua l. These improvised techniques are not minor stylistic differences.

In Ohio OVI investigations , the one-leg stand test frequently becomes an exercise in officer discretion rather than standardized evaluation. Small deviations in timing, instruction, and interpretation can dramatically affect how performance is judged. When those deviations are ignored, the test’s reliability is ove

Police officers routinely testify that field sobriety tests are standardized. That word carries weight. It suggests precision, consistency, and scientific reliability. But when officers are asked to explain their own training, that certainty often collapses. In Ohio OVI investigations , officers frequently cannot recall the instructions they were taught to give, the order they were taught to follow, or the purpose behind each step of a field sobriety test. What remains is fa

When people picture field sobriety tests during an OVI stop, they often imagine the One-Leg Stand (“OLS”) . It looks simple. It sounds simple. And officers routinely treat it as a reliable indicator of impairment. But the OLS test is one of the most misunderstood and misapplied tools used in Ohio OVI investigations. Despite its reputation as a straightforward balance test, the OLS is highly sensitive to physical limitations, medical conditions, anxiety, roadside environments
