What I've Seen Go Wrong in DUI Arrests—And How a Our Attorneys Can Help You Fight Back
When I sit down with someone facing a DUI charge, the first thing I ask about is how the stop happened. That moment when the lights flash behind your car sets everything in motion—and if something goes wrong at that point, it can impact the entire case. Police officers must follow the law like everyone else. When they don't, it opens the door to having charges dismissed or evidence thrown out. I've seen it happen time and time again. But those outcomes don't happen by chance. They happen because a private defense attorney digs deep and challenges every part of the arrest.
Let me walk you through some of the most common mistakes police make in DUI stops—and why having your own attorney is the key to exposing those errors.
The Stop Lacked Legal Justification
The police can't pull someone over just because they feel like it. There has to be a valid reason—something they can point to that shows a traffic violation or a reason to believe you were driving impaired. Maybe they claim you swerved or rolled through a stop sign. But if that didn't actually happen, or if it was something minor that doesn't support suspicion of DUI, that stop may not hold up in court.
A private attorney will push for dash cam footage, body cam footage, dispatch logs, and any other detail that shows whether the stop was legal. If it wasn't, the evidence collected afterward could be suppressed. Without evidence, there's no case.
Field Sobriety Tests Were Done Incorrectly
I've sat through countless hearings where officers testify about field sobriety tests. What many people don't realize is how easy it is for these tests to be performed or scored wrong. The tests aren't simple walk-the-line games. They're structured procedures with strict instructions. If the officer skips a step, gives confusing directions, or misjudges your performance, the results lose credibility.
Your own lawyer will know what's required and what isn't. I often compare the officer's testimony to training manuals and police protocols. If there's any deviation, that gives us a strong argument to challenge the arrest. Don't expect a public defender to have the time or resources to do that. You need someone whose focus is squarely on defending you.
The Breath or Blood Test Was Mishandled
Chemical tests are often treated like a slam dunk for the prosecution, but they're not foolproof. I've worked on cases where breath machines weren't calibrated correctly. In others, the person administering the test wasn't certified. Sometimes, blood samples were stored improperly or tested too late. These are serious problems—and they're more common than you might think.
As your lawyer, I'll review maintenance logs, certification records, and every document related to how your test was performed. If there's a weakness, I'll find it. If that test result is flawed, it can be excluded from the evidence. Without a private attorney who's dedicated to your defense, those opportunities are often missed.
Officers Didn't Read Your Rights
You've probably heard the term "Miranda rights." If you're under arrest and the police start asking questions, they're required to inform you of your right to remain silent and your right to an attorney. If they fail to do that, anything you say might be thrown out.
I've defended people who made statements without realizing they didn't have to. When we challenge those statements and show that the officer never explained their rights, those words can't be used in court. The key is having someone on your side who knows how to raise that issue and present it effectively.
Body Camera Footage Tells a Different Story
One of the biggest developments in DUI defense is body-worn camera footage. That video can show exactly what happened—and in many cases, it contradicts the officer's report. I've seen footage where the person arrested was polite and cooperative despite the officer claiming they were aggressive. I've seen people walk steadily and follow directions even though the officer wrote they were stumbling.
That kind of discrepancy can make or break a case. But you only get access to that footage if someone requests it right away and reviews every second of it. A private attorney won't let that opportunity slip by.
The Officer Didn't Follow Training Guidelines
Police officers go through specific training on how to detect impaired drivers and conduct DUI investigations. That training comes with a manual and a checklist of things they're supposed to do. If they skip steps, take shortcuts, or do things they weren't trained to do, it can undercut their credibility.
I've challenged officers on the stand about these mistakes. When they admit they didn't follow protocol, judges and juries take notice. That only happens when your attorney understands the material and is prepared to ask the right questions. You don't get that kind of preparation from someone juggling a huge public defender caseload.
There Was No Real Sign of Impairment
Sometimes, people get arrested for DUI even though they were driving normally and didn't show clear signs of being impaired. I've had cases where the officer said my client "seemed nervous" or "smelled like alcohol." That isn't enough on its own.
Without things like poor driving, slurred speech, or unsteady balance, the case becomes weak. When that's pointed out clearly by a defense lawyer who's committed to you, prosecutors often back down or courts throw the case out.
Paperwork Errors and Missing Documents
DUI cases generate a mountain of paperwork—police reports, lab results, video logs, witness statements, certifications, and more. All of it has to line up. If something is missing, signed wrong, or filed late, it can cause real problems for the prosecution.
One of my roles is to review every document with a fine-tooth comb. I'm not just looking for typos—I'm looking for legal defects that could cause evidence to be thrown out. That kind of careful analysis isn't something the average defendant can do alone.
The Police Assumed You Were Guilty
I've seen situations where the officer already made up their mind before the stop even happened. Maybe they followed someone from a bar or pulled someone over late at night and assumed the worst. When an officer goes into a situation with that attitude, it affects how they write their report and how they interpret everything they see.
That kind of bias is hard to catch unless someone digs deep. I look for patterns in an officer's history, see how they've handled other cases, and question whether their judgment was fair. These are the kinds of defenses that only come out when you have an attorney focused entirely on your outcome.
How a Private Attorney Makes the Difference
The legal system can feel stacked against you when you're facing a DUI. Prosecutors are aggressive. The rules are strict. And the penalties can be life-changing. But I've seen what happens when someone has a strong legal advocate. Weak cases fall apart. Good people get a second chance. And outcomes shift dramatically.
Hiring your own lawyer means putting your future first. It means having someone who works for you, not the court system. Someone who will listen, fight, and stay committed from start to finish. That's how DUI charges get dismissed—by exposing every mistake and holding the system accountable.
FAQs: Common Police Mistakes and DUI Defense
Can a DUI be dismissed if the officer didn't have a reason to stop me?
Yes. If the officer lacked a lawful reason to pull you over, that's called an illegal stop. Any evidence they gathered after that, like field sobriety tests or chemical tests, may be thrown out. Without that evidence, the case often falls apart.
What if the officer didn't read me my rights?
If you were arrested and questioned without being informed of your rights, your statements might be excluded from court. This can weaken the prosecution's case and help your defense.
Can field sobriety test results be challenged?
Absolutely. These tests are often done incorrectly or judged unfairly. A private attorney can review how the tests were conducted and argue that the results are unreliable.
Are breath tests always accurate?
No. Machines must be calibrated and maintained properly. The person giving the test must be trained and certified. If any part of that process is flawed, the test result can be challenged.
What happens if the police lose the video footage?
If crucial video evidence is lost or not preserved, that can raise serious questions about fairness. A private attorney can argue that your rights were violated and ask the court to take action.
Is it possible to challenge a DUI if I admitted to drinking?
Yes. Even if you said you had a few drinks, that doesn't prove you were impaired. If your rights weren't respected, or the tests were flawed, your statements might not matter.
Can paperwork errors really get a DUI dismissed?
They can. Some errors are serious enough to undermine the prosecution's case. Others reveal bigger problems with how the investigation was handled.
Do public defenders catch these police mistakes?
Public defenders work hard, but they're often handling too many cases at once. They might not have time to review every detail. That's why having your own attorney makes a major difference.
Can I win a DUI case without going to trial?
Yes. Many DUI cases are dismissed or reduced before trial because of legal issues. But those opportunities are often missed unless you have a lawyer who knows how to find them.
How soon should I hire a private attorney after a DUI arrest?
As soon as possible. The earlier your lawyer starts reviewing the case, the better chance you have of uncovering police mistakes and building a strong defense.
