The police officer said you failed the breathalyzer test. That feels definitive. You probably think that one number decides everything. The prosecution is counting on that feeling. They’re counting on you to accept this result as fact and move forward, assuming guilt is inevitable. Except that the breathalyzer result might be completely wrong.
A DUI lawyer in Miami sees this pattern constantly. The clients always enter assuming that the Breathalyzer has proved their case. However, they do not know how the machine works or what might cause an inaccuracy in the test. The prosecutor knows this and uses it to his advantage. That’s part of their strategy. They present evidence that looks scientific and assume you’ll accept it without challenge.
Here’s what Piotrowski Law Miami understands that most people don’t: prosecutors build DUI cases on assumptions. They assume you don’t know how field sobriety tests actually work. They assume you won’t question the traffic stop. They assume you’ll accept their version of events without understanding your legal options. When you walk into a courtroom without this knowledge, you’re already losing.
The Breathalyzer Isn’t Automatically Accurate
Police departments maintain these machines, but maintenance standards vary widely. Some departments calibrate their breathalyzers regularly. Others don’t. A machine that hasn’t been properly calibrated can give readings that are completely off. Your blood alcohol level might be .05 when the machine says .09.
The prosecution won’t volunteer this information. They’ll present the result and move forward. They’re hoping you accept it at face value. A proper DUI defense requires questioning the machine’s last calibration date, who performed the calibration, and whether the officer followed proper protocol when administering the test.
Temperature matters too. Breathalyzers are sensitive to temperature. A mouth temperature that’s higher than normal can affect the reading. Some diseases and food can give false readings. Acid indigestion is very common. People don’t say anything about this. Neither does the prosecution raise this issue. These are all genuine considerations.
The Traffic Stop Could Be Unlawful
A police officer must have some good reason for pulling you over on the road. He cannot stop your car just because he feels like it. This is the law. Nevertheless, many DUI arrests happen after an illegal traffic stop. Maybe they suspected something about your driving that turned out to be nothing.
If the traffic stop was illegal, everything that followed can be thrown out. The breathalyzer test. The field sobriety tests. All of it. The prosecution doesn’t want you knowing this. They want you focused on the test results and the charges, not on whether the stop itself was constitutional.
A good defense attorney reviews the dashcam footage and police report carefully. They look for reasons the stop violated your rights. Was there actually a traffic violation? Did the officer make it up? Was there reasonable suspicion or just a hunch? These questions matter legally even when they seem small.
Field Sobriety Tests Aren’t What You Think They Are
The one-legged stand test. The horizontal gaze nystagmus test. These sound scientific. Police present them as reliable measures of impairment. They’re not nearly as reliable as the prosecution suggests.
Plenty of sober people fail these tests. Anxiety affects balance. Certain medical conditions affect coordination. Uneven pavement affects the one-legged stand test. Lighting affects the eye test. Shoes matter. Your physical fitness matters. Age matters. Nobody’s telling you this when the officer is asking you to perform.
The prosecution knows these tests are subjective. They also know most people don’t understand how subjective they are. They present them as if they’re standardized medical evaluations. They’re actually officer interpretations.
You Have Rights During the Stop and Beyond
This is where it gets exciting. You have the right to keep quiet. You have the right to turn down certain tests. You have the right to talk to a lawyer. The state depends upon you not exercising your rights.
When an officer asks you if you’ve been drinking, you don’t have to answer that question. When the officer asks you to take the field sobriety test, you can refuse it. When the officer asks whether you will blow into the Breathalyzer, you have the right to say ‘no.’
The prosecution doesn’t emphasize these rights. They move through the interaction assuming compliance. They get what they want because people don’t know they can say no. That changes things.
The Reports Might Contain Contradictions
Police reports are written after the arrest. The officer writes down what they remember seeing. Sometimes they remember things differently from how they actually happened. Sometimes the report contradicts the dashcam video. Sometimes statements don’t match the timeline.
A DUI lawyer in Miami looks for these gaps. Did the field sobriety test instructions get given correctly per the book? Does the police report’s account of the situation line up with the video? Have they claimed that you said things you did not actually say? Do their accounts match your actual performance?
These contradictions matter in court. They’re ammunition for your defense.
The Prosecution Has the Burden of Proof
This is fundamental. They have to prove you guilty. It is not your responsibility to prove yourself innocent. There must be proof beyond a reasonable doubt on the part of the prosecution. If the evidence presented has any faults, such as an error with the breathalyzer test or a faulty traffic stop, these issues will affect your case.
People plead guilty because they think they have no other option, without knowing how weak the prosecutor’s case is. They accept the evidence as presented without considering the questions a good attorney would ask.
Your License and Your Life Are At Stake
A DUI conviction costs money. It costs you your driving privileges. It costs your job if you need to drive. It affects insurance for years. It shows up on background checks. Some professions won’t hire you. Landlords see it. It follows you.
The prosecution knows most people panic when arrested. They’re trying to make this go away quickly. That panic leads to quick guilty pleas. That’s exactly what they want.
What Happens When You Actually Fight Back
When your DUI lawyer in Miami starts asking questions about the breathalyzer calibration, the traffic stop, and the administration of the field sobriety test, things change. The prosecution either produces solid evidence or they don’t. Sometimes they can’t. Sometimes the case falls apart.
Maybe the charge gets reduced. Maybe it gets dismissed. Maybe it goes to trial, and you win. You won’t know unless you fight it properly. The prosecution is banking on you not doing that.
The Choice is Yours
You can accept the charges and move forward. You can accept the prosecution’s version of events. Many people do. Or you can find a DUI lawyer who knows what questions to ask and what evidence to challenge. The difference between these two paths changes your future.
