Field Sobriety Tests in Florida DUI Cases
Are field sobriety tests mandatory in Florida?
Roadside field sobriety exercises are generally voluntary. They are different from lawful commands during a traffic stop and from breath, blood, or urine testing under Florida’s implied-consent laws. Declining an exercise does not require an officer to end the investigation or prevent an arrest based on other evidence.
A refusal may be offered as evidence, but whether it is admissible depends on the circumstances, including what the officer said about the consequences. The court’s decision in Howitt v. State discusses this distinction. Follow lawful commands and do not physically resist.

What Are Field Sobriety Tests?
Field sobriety tests are roadside exercises used by law enforcement during a DUI stop.
Common DUI field sobriety exercises include:
Walk-and-turn
One-leg stand
Horizontal gaze nystagmus
Finger-to-nose
Alphabet or counting exercises
These tests are designed to help officers look for signs of impairment, but the results can be subjective.
Why Field Sobriety Tests Can Be Challenged
Field sobriety tests are not perfect. Poor performance does not always mean a person is impaired. Medical issues, nerves, fatigue, injuries, footwear, road conditions, and unclear instructions can all affect how someone performs.
Field sobriety tests may be challenged when:
The officer gave unclear or improper instructions
The test was performed on uneven ground
The driver had medical issues or injuries
Poor lighting or traffic conditions affected performance
The officer misinterpreted normal behavior as impairment
Field Sobriety Tests and Breath Tests
Field sobriety tests are often used together with breath testing. If you performed poorly on roadside exercises and later blew over the legal limit, the State may try to use both pieces of evidence against you.
Refusing a lawful chemical test can create separate license and criminal consequences. Read about breath-test refusal in Florida and challenging breath-test evidence. The administrative suspension statute, section 322.2615, addresses chemical-test results and refusals; it should not be confused with roadside exercise requests.
What Happens After Field Sobriety Tests?
If an officer believes the field sobriety tests show impairment, you may be arrested for DUI.
After arrest, your license may be affected quickly, and you may only have a short time to act.

Can a DUI Be Reduced After Performing Poorly on Field Sobriety Tests?
Yes, in some cases. Failed field sobriety tests do not automatically mean a DUI conviction.
A DUI may be challenged or reduced depending on:
The legality of the stop
The officer’s instructions
Video evidence
Breath or urine test results
Medical or physical explanations

Field sobriety test FAQs
Can you refuse field sobriety tests in Florida?
Roadside exercises are generally voluntary, but refusal does not prevent an arrest. Whether a refusal can be introduced in court depends on the facts and what the officer communicated. Chemical testing involves different rules.
Does poor performance prove impairment?
Not by itself. A defense review can compare the officer's description with the video, instructions, testing conditions, and documented physical or medical limitations. The complete evidence matters.
Can the charge be reduced or dismissed?
That depends on the evidence and available legal arguments. Performing poorly on an exercise does not automatically establish guilt, and a reduction or dismissal cannot be promised.
What exercises are commonly used?
Officers commonly use walk-and-turn, one-leg stand, and horizontal gaze nystagmus. Other exercises may also appear in the reports or video.
What should I tell my attorney?
Describe the instructions, your responses, any injuries or balance problems, footwear, lighting, and road surface. Preserve relevant records and tell your attorney where video or witnesses may be found.
