How Police Mistakes Can Get Your Florida DUI Case Thrown Out

A Florida DUI Attorney Explains How Body Cam Problems, Faulty Testing, and Unlawful Stops Can Turn a DUI Arrest Into a Dismissal

If you were arrested for DUI in Florida, there is a strong chance the police made mistakes that can be used in your defense. After handling DUI cases for many years, I can tell you that police officers often rush decisions, cut corners, or apply procedures incorrectly. Those mistakes can directly affect the legality of the stop, the reliability of tests, and the credibility of the officer’s conclusions.

When I review a DUI case, I focus on every moment from the time the officer first noticed the vehicle to the final step at the breath testing facility. Police conduct must comply with Florida law at each stage. If they fail to follow the rules, the evidence may be suppressed, which can lead to reduced charges or even dismissal. This is one of the primary reasons people hire a private attorney. I take time to examine what really happened, gather the information the state does not emphasize, and reveal weaknesses that can completely change the outcome of the case.

Florida statutes outline how officers must conduct stops, how breath tests must be administered, and what conditions must be met before an arrest is lawful. The laws governing DUI arrests describe the need for reasonable suspicion to initiate a traffic stop and probable cause to arrest a driver. They also set strict requirements for breath testing procedures, maintenance, calibration, observation periods, and paperwork accuracy. When officers fail to follow these rules, the evidence is compromised.

The strength of a DUI case often rests on the officer’s behavior. If the stop was unlawful, all evidence that follows may be thrown out. If field sobriety exercises were administered incorrectly, the results should not be trusted. If the breath test device was not maintained properly, the reading is unreliable. When I identify these issues, I can challenge the state’s evidence and push for dismissal or reduction to a lesser charge such as reckless driving.

Unlawful Traffic Stops, When Police Lack the Legal Right to Pull You Over

One of the most important issues in every DUI case involves the legality of the stop. Florida courts require officers to have reasonable suspicion that a traffic law was violated before pulling a driver over. If the officer cannot explain a clear and specific reason for the stop, the entire case may collapse.

Florida statutes governing traffic enforcement describe what officers may and may not do. The laws explain that an officer must observe conduct that indicates a traffic violation or impairment. Vague statements such as “the driver looked suspicious” or “the vehicle was moving strangely” are not enough. The officer must articulate facts that support the decision to stop the vehicle.

As a private attorney, I analyze the body cam footage and police reports to determine whether the stop was lawful. Many cases involve reasons that do not hold up under scrutiny, such as:

• Drifting within a single lane

• Touching the lane marker without crossing it

• Driving slightly under the speed limit

• Leaving a parking lot late at night

• Brief hesitation at a traffic light

These actions are common and legal. When the stop is based on assumptions rather than facts, I file a motion to suppress the evidence. Judges frequently grant these motions, which forces the state to drop the DUI charge because the traffic stop was unconstitutional.

The difference between winning and losing can come down to how the initial stop is presented to the judge. Without a private attorney, many people never know that the officer lacked sufficient justification to pull them over. I take the time to uncover these issues and present them in a clear, persuasive way.

Body Camera Problems That Can Destroy the State’s DUI Case

Body cam footage is one of the most important tools in defending a DUI case in Florida. The camera does not lie. It captures slurred speech that is not actually slurred, stumbling that never occurred, and instructions that were unclear or impossible to follow. It often shows that the officer exaggerated or misinterpreted normal behavior.

Florida law encourages the use of body cameras to support accurate documentation of traffic stops and arrests. Although body camera use is not mandated in every agency, when a department issues cameras, officers must follow internal protocols for recording, saving, and uploading footage. When that footage is missing, incomplete, or inconsistent with the officer’s report, it creates significant doubt.

I often see the following body cam problems:

• Cameras not activated when required

• Footage that cuts out during critical moments

• Poor audio quality that distorts instructions

• Angles that prevent clear observation of field sobriety exercises

• Officer statements that contradict what the camera shows

• Footage that was not preserved properly by the department

Body cam footage is one of the most powerful tools I use as a Florida DUI Attorney. I review every second of video. If the officer’s story does not match what happened, I use that to challenge probable cause. Judges take credibility issues seriously, and when I demonstrate that the officer’s claims are inconsistent with the recording, the state’s case weakens dramatically.

Without an attorney who knows how to analyze body cam footage, many people miss opportunities to challenge the evidence. A private attorney is essential because I know what to look for, how to compare the footage with the report, and how to present contradictions to the court.

Faulty Field Sobriety Exercises, How Police Mistakes Turn Strong Cases Into Weak Ones

Field sobriety exercises are one of the most misunderstood parts of DUI cases. Many people believe they failed these tests because they were nervous, tired, or confused. In reality, many officers administer the tests incorrectly or instruct drivers in a way that guarantees failure.

Florida case law and DUI enforcement standards explain how these exercises must be conducted. Officers must give clear instructions, demonstrate the exercise properly, and use standardized scoring criteria. When they fail to follow these steps, the results lose value.

Common mistakes include:

• Giving unclear or rapid instructions

• Demonstrating the exercise incorrectly

• Using nonstandard tests that have no scientific support

• Failing to consider medical limitations

• Conducting exercises on uneven, dark, or unsafe surfaces

• Recording only part of the exercise on body cam

I often use these mistakes to undermine the officer’s conclusions. When the judge sees that the tests were unreliable, the state’s evidence becomes significantly weaker. In many cases, this leads to reduced charges or dismissal.

Breath Test Errors, Device Malfunctions, and Unreliable Results

Breath testing is highly technical, and Florida law sets strict rules for how these tests must be conducted. Before administering a breath test, the officer must observe the driver continuously for a set period. The testing device must be properly maintained, calibrated, and documented according to regulations.

Florida’s DUI testing statutes describe:

• Maintenance and calibration schedules

• Certification requirements

• Observation periods

• Approved instruments

• Required paperwork

• Testing protocols

If any step is skipped or performed incorrectly, the results may be unreliable.

I regularly challenge breath test results by examining:

• Calibration logs

• Maintenance records

• Operator certifications

• Observation period compliance

• Interfering substances

• Device error messages

• Mouth alcohol contamination

• Environmental conditions

Because these issues are complex, a private attorney is essential. I know how to obtain records from the testing agency, how to review them, and how to identify errors that can lead to suppression of results.

Real Case Example From My Practice

One of my clients in Pinellas County was arrested after an officer claimed he saw “swerving” and “signs of intoxication.” The officer wrote that my client stumbled, slurred his speech, and failed all field sobriety exercises. Based on that report, the state believed they had a strong case.

When I obtained the body cam footage, it told a very different story. My client did not stumble at all. He followed the officer’s instructions calmly, and there was no slurred speech. The only “swerving” involved avoiding debris in the road, which was visible in the footage.

I also reviewed the breath test records and found that the testing device had a maintenance entry showing irregularities within the same week. Combined with the body cam contradiction, I filed a motion to suppress the arrest and the breath test results.

The judge granted the motion, and the state dismissed the DUI. My client did not face jail, did not lose his license, and kept his clean record. This is one example of how police mistakes, when exposed correctly, can completely collapse a DUI case.

Why You Need a Private Attorney To Uncover These Police Errors

Law enforcement agencies do not highlight their own mistakes. Prosecutors usually rely on the officer’s version of events, assuming the reporting is accurate. Body cam footage, radio logs, maintenance records, GPS data, and procedural manuals often tell a more complete story, but you need someone who knows how to find and interpret them.

A private Florida DUI Attorney can:

• Demand all body cam and dash cam footage

• Review every second of video for inconsistencies

• Subpoena breath testing maintenance records

• Examine probable cause for the stop

• Challenge unlawful detention

• Identify mistakes in field sobriety exercises

• Present a strong suppression motion

• Push for reduced charges or dismissal

When errors exist, I use them aggressively. When the state realizes its case has problems, negotiations shift immediately. Many times, the result is a reduction to reckless driving, dismissal of DUI charges, or suppression of key evidence.

Without a private attorney, evidence remains unchallenged, and judges never see the weaknesses that could have changed the entire outcome.

Can my DUI be dismissed if the officer did not turn on the body camera?
It depends on the circumstances. Some agencies require officers to activate their cameras during stops, while others follow internal policies that encourage recording. If the officer failed to activate the camera during critical moments, I review whether this violates agency policy and whether the officer’s statements lack credibility. Courts take missing footage seriously when the officer’s account cannot be verified. While a missing camera does not automatically dismiss the case, it creates an opening for strong suppression arguments.

What happens if the field sobriety exercises were administered incorrectly?
Improper administration of field sobriety exercises is one of the most common weaknesses in DUI cases. These tests must follow standardized procedures. If the officer gives unclear instructions, demonstrates the exercise poorly, or uses a location that makes the test unreliable, I use these issues to challenge the validity of the exercises. Judges often discount or reject the results when these errors appear, which weakens probable cause for the arrest.

Can I challenge the breath test results even if I blew over the limit?
Yes. Breath test results are not automatically accepted by the court. The device must be properly maintained and calibrated, and the officer must follow correct procedures. Florida law requires specific observation periods, correct documentation, and certified operators. If any of these conditions were not met, the result may be suppressed. I have won many cases where the breath test was thrown out due to procedural mistakes or maintenance issues.

What if the officer exaggerated or misstated what happened?
Body cam footage is the best tool for addressing this. I compare the officer’s report with the video. If the officer described slurred speech, stumbling, or confusion that does not appear on the recording, I expose this inconsistency to the court. Judges do not tolerate inaccurate reporting, and these contradictions can severely damage the state’s case.

Can a faulty traffic stop result in dismissal of my DUI?
Yes. If the officer lacked reasonable suspicion to pull you over, all evidence gathered afterward may be thrown out. I examine whether the officer gave a clear reason for the stop and whether that reason is legally valid. Stops based on vague impressions or minor lawful driving behavior can be challenged successfully. When the judge suppresses the stop, the DUI charge cannot proceed.

Do police have to follow strict rules before arresting someone for DUI?
They must comply with constitutional and procedural rules. Officers need probable cause to make an arrest. They must administer tests correctly and follow department policies. If these rules are violated, the evidence may be suppressed. I use these issues to challenge the arrest and seek dismissal.

What if the officer claimed signs of impairment that were actually caused by fatigue, nerves, or medical issues?
This is very common. Red eyes, shaky hands, difficulty balancing, and confusion can stem from many sources unrelated to alcohol. I present medical records, witness statements, and body cam footage to show alternative explanations for these signs. When judges see the full picture, the state’s case weakens.

Why do I need a private attorney instead of relying on the public defender?
Public defenders work extremely hard, but they often carry heavy caseloads that limit the time they can dedicate to each DUI case. A private attorney can investigate every detail, review all footage, cross check officer statements, and challenge technical evidence. These steps are critical for identifying police mistakes that can lead to dismissal or reduced charges. DUI defense is detail oriented, and those details determine the outcome.
