Cops Just Make Stuff Up Sometimes

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 manual. These improvised techniques are not minor stylistic differences. They fundamentally change what the test is and what it purports to measure. When officers deviate from the manual, the test stops being standardized and becomes discretionary.

Early in any analysis of this issue, it matters to understand that these tests are part of the broader system of field sobriety tests that rely on strict adherence to training standards. When officers invent steps, the foundation erodes.

Gestures Replace Clear Instructions

Officers are trained to give specific verbal instructions. Those instructions are supposed to be complete and consistent.

Instead, officers often rely on gestures. They point, wave, or motion through parts of the test without clearly explaining what the subject is expected to do. Gestures are interpreted differently by different people. They are not standardized communication.

When performance later deviates from what the officer had in mind, the subject bears the blame for unclear instruction.

Added Balancing Requirements Appear Out of Nowhere

The manuals do not require subjects to balance in exaggerated or prolonged ways beyond the test’s parameters.

Yet officers frequently expect rigid posture, unnatural stillness, or extended balance that goes beyond the test design. Normal adjustments are treated as failures. Movements that were never prohibited become negative observations.

These added requirements are not grounded in training. They are inventions layered onto the test in the moment.

Sequencing Changes Alter the Test Itself

The order of instructions and movements matters. Sequencing is part of standardization.

Officers routinely change the order in which instructions are given, demonstrations occur, or actions are performed. Sometimes instructions are delivered after the test has begun. Other times demonstrations are partial or skipped entirely.

When sequencing changes, the test changes. That is not a technicality. It is a substantive deviation.

Non-Standard Counting Instructions Create Confusion

Counting is meant to be structured and predictable.

Instead, officers often alter pace, tone, or method without explanation. Subjects are criticized for counting too slowly, too quickly, or incorrectly, even though the officer never articulated a clear standard.

This problem closely mirrors the issues seen in clue counting, where undefined expectations are later treated as objective failures.

Why Improvisation Matters More Than Officers Admit

Standardized tests derive their legitimacy from uniform administration. Improvisation defeats that purpose.

When officers cannot articulate what comes from the manual and what comes from habit, the test’s reliability is undermined. The presence of unauthorized steps shows that the test being administered is not the test that was validated.

In Ohio OVI investigations, that distinction can be decisive.

The Takeaway

Field sobriety tests are not invalid because drivers perform poorly. They are vulnerable when officers do not follow their own manual.

Unauthorized gestures, added balancing demands, altered sequencing, and non-standard counting instructions reveal a deeper problem. The tests are often administered as remembered, not as written.

At Harmony Law, we examine whether officers followed training or substituted it with improvisation. When standardized procedures give way to made-up steps, that deviation matters.
