Understanding what the field sobriety exercises are is one thing. Knowing how they function in your case is another. At the roadside they sit at a hinge point. You are asked to perform them, your performance is graded, that grade helps the officer decide to arrest, and the video and report then become evidence the State uses at trial. Under State v. Meador, 674 So. 2d 826 (Fla. 4th DCA 1996), the physical exercises enter as the officer’s lay observations, which shapes every step that follows.
This gate walks that chain. Whether you could refuse, how your performance feeds the probable cause for an arrest, how the bodycam compares to the written report, and what changes when drugs rather than alcohol are suspected. Each link is a place to push.
The roadside exercises are a hinge. They are voluntary, they feed the arrest decision, and they become evidence whose value depends on how they were given and recorded.
Where I press, link by link
The chain that runs from the request to the evidence at trial gives a defense several places to push, and I work each one. At the request stage the question is whether the officer even had the reasonable suspicion needed to ask, and whether the stop was lawful in the first place, which ties into the search and seizure issues that decide many DUI cases. At the performance stage the question is how the exercises were given, because the only validity the standardized battery ever claimed depends on the officer following the protocol he was trained to follow. At the arrest stage the question is whether your roadside performance, taken with everything else the officer saw, truly added up to probable cause, or whether the officer worked backward from a decision he had already made. And at the evidence stage the question is what the body camera shows next to what the report says, because the video is often the most honest witness in the case.
Two legal points run underneath all of it. First, the psychomotor exercises come into a Florida courtroom only as lay observations under State v. Meador, not as science, so the State should not dress them up with the words test, passed, failed, or points. Second, the exercises are voluntary, and you can decline them without the automatic license penalty that follows a refusal of the breath or blood test after a lawful arrest. As an NHTSA field sobriety instructor I know the protocol the officer was trained on, so I can show a jury the exact point where the roadside investigation in your case left the standard.
I started out as an Assistant Public Defender in Florida’s Thirteenth Judicial Circuit, in Tampa, and today I am one of six ACS-CHAL Forensic Lawyer-Scientists in Florida and an NHTSA-qualified field sobriety instructor. I was trained to administer this battery and to teach the officers who give it, so I can stand in front of a jury and show the exact point where the roadside exercises in your case left the standard.

The four questions this gate answers
Questions About Your Case
Do field sobriety exercises decide my case?
Rarely on their own. They are one piece of a chain that runs from the request, to your performance, to the arrest, to the evidence at trial. Each link can be challenged, and a weak roadside performance does not have to control the outcome.
Can I refuse field sobriety exercises in Florida?
Yes. They are voluntary, and there is no automatic license suspension for declining them, unlike the breath or blood test after a lawful arrest. Whether declining helps depends on the facts, and the law on using a refusal is contested.
How do the exercises lead to an arrest?
An officer needs only reasonable suspicion to ask you to perform them, and your performance, along with driving, odor, and statements, can supply the probable cause for an arrest. We attack each input to that decision.
Does the video matter more than the report?
Often, yes. The bodycam can contradict the written report on the surface, the instructions, the timing, and your actual performance, and those gaps are powerful at trial.
What if drugs are involved?
The field sobriety analysis still applies, and the drug-specific issues, the eye findings, the drug recognition evaluation, and the toxicology, are covered in the drugged driving section.

This page is general information, not legal advice, and it does not create an attorney-client relationship. Field sobriety exercises in Florida are governed by case law and by section 316.193, Florida Statutes. Procedures and rules change, and every case turns on its own facts. Past results do not guarantee a similar outcome.
