Yes. You can legally refuse every field sobriety test in New York, and there are no automatic administrative penalties for doing so.
That is a fact that surprises most people, because in the moment — standing on the side of the road with flashing lights behind you — everything about the encounter feels mandatory. But field sobriety tests are voluntary. Understanding your rights at a DWI stop is one of the most important things you can do before you ever need them.
The Critical Distinction: FSTs vs. Chemical Tests
| Field Sobriety Tests (FSTs) | Chemical Test (Breathalyzer at Station) | |
|---|---|---|
| When | Roadside, before arrest | Police station, after arrest |
| Voluntary? | Yes — completely voluntary | Subject to Implied Consent law |
| Penalty for Refusing | None — no automatic license action | 1-year license revocation + $500 fine |
| Used For | Establishing probable cause for arrest | Providing BAC evidence for prosecution |
| Evidence Value | Subjective — officer interpretation + video | Objective — numerical BAC reading |
The FSTs — the walk-and-turn, one-leg stand, and eye test — happen at the roadside before arrest. They are investigative tools the officer uses to build probable cause. Refusing them does not trigger Implied Consent penalties that kick in when you refuse the official chemical test at the station after arrest.
What Happens If You Refuse
The officer will likely arrest you anyway. The officer can still use other observations to establish probable cause. In many cases, the officer has already decided to arrest before the FSTs even begin.
Your refusal cannot be used against you the same way a chemical test refusal can. Implied Consent specifically applies to chemical tests after arrest. The prosecution cannot argue consciousness of guilt based on FST refusal.
You avoid creating the prosecution’s best evidence. That video of every stumble, wobble, and moment of hesitation becomes the prosecution’s star exhibit at trial. Even stone-cold sober people fail these tests regularly. For a deeper look at the specific tests and their documented accuracy issues, see our post on standard field sobriety tests in New York.
Why Sober People Fail
NHTSA research shows that even under controlled laboratory conditions, the most accurate test (HGN) has roughly 77% accuracy. Walk-and-turn is around 68%. One-leg stand is about 65%.
Environmental factors. Uneven pavement, gravel, highway traffic, flashing lights, wind, rain, darkness.
Physical conditions. Age, weight, knee or back injuries, inner ear problems, neurological conditions, fatigue, prescription medications, and footwear.
Psychological pressure. Nervousness alone can cause the hesitation and unsteadiness that officers count as failed indicators. The tests cannot distinguish between impairment and panic.
The PBT Is Also Voluntary
The portable breath test — the small handheld device at the roadside — is also voluntary. Refusing it does not trigger Implied Consent penalties. The test that carries mandatory penalties is the official chemical test at the station after formal arrest.
How to Refuse Politely
Keep it simple: “Officer, I respectfully decline to perform the field sobriety tests.”
You do not need to explain why. A calm, clear, polite refusal is enough. You also have the right to remain silent beyond providing license, registration, and insurance. You may also have a limited right to speak with an attorney before deciding on the chemical test at the station.
What You Must Provide
License, registration, and insurance when asked. Exit the vehicle if instructed (Pennsylvania v. Mimms). Submit to a chemical test after arrest — or accept the Implied Consent penalties (automatic 1-year license revocation + $500 civil penalty).
When Refusing Makes the Most Sense
If you have been drinking, performing the tests gives the prosecution video evidence. If you have not been drinking, the tests still carry risk because sober performance can be interpreted as impaired.
Your DWI defense attorney will have more to work with if there is no FST video for the prosecution to play in front of a jury. And whether the results are admissible in court depends on several factors that vary case by case.
