One-Leg Stand
One-Leg Stand Test in Ohio OVI Cases
The one-leg stand test is one of the simplest-looking field sobriety tests. It is also one of the easiest to misinterpret.
Standing on one foot while counting out loud does not measure intoxication. It measures balance, coordination, and the ability to perform under pressure. Those are not the same thing.
The test assumes a level of physical stability and situational calm that rarely exists during a roadside stop.
What the One-Leg Stand Test Is Supposed to Measure
The one-leg stand is intended to divide attention between a mental task and a physical task. The theory is that alcohol or drugs may make it harder to do both at the same time.
That is the framework.
To apply it, the test requires clear instructions, proper demonstration, an appropriate surface, and consistent timing. When those elements are missing or rushed, the conclusions drawn from the test become unreliable very quickly.
This is not a flexible test.
Why This Test Is Especially Sensitive to Conditions
The one-leg stand leaves very little margin for error. Even small issues can affect performance.
Balance problems, past injuries, age, fatigue, footwear, uneven pavement, weather, or simple nervousness can all influence how someone performs. None of those factors require alcohol or drugs.
Many sober people would struggle to perform this test exactly as instructed under roadside conditions. That reality is often ignored when the results are later described.
How Officers Are Trained to Score the Test
Officers are trained to look for specific “clues” during the one-leg stand. Those clues are supposed to be observed under controlled conditions and counted consistently.
In practice, the test often becomes subjective.
Swaying, raising arms, hopping, or putting a foot down are frequently treated as signs of impairment without meaningful context. What matters later is whether the test was administered correctly and whether the observations actually support the conclusions being made.
Relationship to Other Field Sobriety Tests
The one-leg stand is commonly administered alongside the walk-and-turn. Both are balance-based, divided-attention exercises, and both are affected by the same non-alcohol-related factors.
Issues that appear during the one-leg stand often overlap with issues seen on the walk-and-turn. That overlap matters when these tests are used together to justify an arrest or support further testing.

How the One-Leg Stand Is Evaluated Later
Like other field sobriety tests, the one-leg stand is not judged in isolation.
Video footage, officer reports, and testimony are compared against what the officer claims to have observed. Small details that seemed insignificant during the stop can take on greater importance later.
The focus is not whether the test was given, but whether it was given properly and whether the conclusions drawn are supported by the evidence.
Why This Test Matters in an OVI Case
The one-leg stand is often used to support probable cause for arrest or to justify requesting a chemical test. When it is administered improperly or relied on too heavily, it can skew how an entire case is viewed.
A careful review looks at what was done, how it was done, and whether the test actually supports the claims being made.
That review frequently changes how a case moves forward.
Talking Through What Happened
During an OVI investigation, many people are told they “failed” the one-leg stand without understanding what the test is designed to measure or how it is supposed to be administered.
A conversation allows us to walk through what happened, explain how the test works in practice, and talk honestly about how it may be viewed in your case.
Clear explanations make it easier to understand where you stand and what actually matters next.
