If you got arrested for DUI in Georgia, the state needs solid evidence to convict you. That evidence can include the traffic stop itself, field sobriety tests, breath or blood results, and anything you said to police. But not all of that evidence holds up in court. Police have to follow strict rules during a DUI arrest, and when they break those rules, a defense lawyer can file a motion to suppress. If a judge grants that motion, the evidence gets thrown out and the state’s case gets weaker, sometimes to the point of dismissal.
This post walks through the types of evidence that can get suppressed in a Georgia DUI case, how the process works, and what you can do if you were arrested in Chatham County or anywhere else in the state.
How Evidence Suppression Works in Georgia DUI Cases
A motion to suppress is a request filed before trial. It asks the judge to keep certain evidence out of the case because police got it in a way that broke the law. Georgia law and the Fourth Amendment both protect drivers from unreasonable searches and seizures. When officers skip a step, ignore a rule, or act without enough legal reason, the evidence they collect can become unusable.
The state carries the burden here. Once the defense raises a problem with how the evidence was gathered, prosecutors have to prove the stop, arrest, or test was lawful. If they can’t, the judge excludes it.
Timing matters a lot. In superior court, motions to suppress generally need to be filed within 10 days of arraignment unless the judge grants more time. State and municipal courts set their own schedules, so deadlines can shift depending on where your case lands. Miss the window and you likely lose the chance to raise the issue at all. This is one more reason to talk to a lawyer early instead of waiting.
Grounds for Suppressing the Traffic Stop
Every DUI case starts the same way: an officer pulls you over. But that stop has to be based on something real. Officers need reasonable suspicion that you broke a traffic law or committed a crime before they can stop you. A hunch is not enough.
Here are common reasons a traffic stop gets thrown out in Georgia DUI cases:
- Weaving once inside your own lane, without any actual traffic violation
- An anonymous tip that police never checked out or confirmed
- A stop that lasted way longer than the reason it started for
- A stop based on a law the officer misread or misunderstood
- A checkpoint that wasn’t set up or run the right way
Checkpoints get their own set of rules. Georgia courts look at whether supervisors picked the checkpoint location for a real safety reason, whether officers stopped every car instead of picking and choosing, and whether the checkpoint was clearly marked and didn’t hold drivers for too long. If police skip these steps, the whole stop can be suppressed.
Dashcam and body camera video often decide these arguments. A report might say you were weaving, but the video sometimes tells a different story.
Challenging Field Sobriety Tests
After the stop, officers usually run field sobriety tests like the walk-and-turn, one-leg stand, and horizontal gaze nystagmus test. These are supposed to follow strict NHTSA rules. When they don’t, the results can be thrown out.
Some common problems include:
- Testing you on a slope, gravel, or uneven ground
- Giving confusing or incomplete instructions
- Ignoring a medical condition, injury, or age issue that affects balance
- Using bad lighting conditions, like glaring headlights, during the test
A low score on one test alone usually isn’t enough for probable cause to arrest you. If your lawyer can show the officer skipped steps or ignored a health issue, the test results may not hold up in court.
Breath and Blood Test Suppression
Georgia’s implied consent law requires officers to read you a specific notice about your right to refuse chemical testing. That notice has to be read correctly and close to word-for-word. If it’s late, wrong, or skipped, the test result tied to it can be suppressed.
Breath test problems that come up often include:
- Skipping the 20 minute observation period before the test
- Using a machine that wasn’t calibrated or inspected on schedule
- Missing maintenance logs for the Intoxilyzer machine
- Physical conditions like GERD or high blood sugar that can throw off the reading
Blood draws come with their own rules. Police generally need a warrant to draw your blood unless a real emergency exists. Courts have made this clear at both the state and federal level. If officers skipped the warrant and can’t show a good reason why, the blood test result can be suppressed. Chain of custody problems, like a sample that wasn’t handled right or got delayed at the lab, can also hurt the state’s case.
Suppressing Statements and Miranda Violations
If police questioned you while you were in custody and didn’t read you your Miranda rights first, anything you said might not be usable in court. This includes questions like “have you been drinking” if asked in a way that counts as custodial questioning. Video and audio recordings from the stop often show exactly when and how these questions happened, which helps a lawyer figure out if your rights were violated.
What Happens at a Suppression Hearing
A suppression hearing happens before a judge, not a jury. The arresting officer usually testifies first about the stop and arrest. Then your lawyer gets to cross-examine the officer and compare his testimony to the video and written report. Judges often catch gaps between what the officer says happened and what the footage actually shows.
There are three possible outcomes:
- The motion is granted in full, and the state loses key evidence, which can lead to a reduced charge or dismissal.
- The motion is granted in part, meaning only some evidence, like a breath test, gets thrown out.
- The motion is denied, and the case moves toward trial, though the issue may still be raised later on appeal.
Even a denied motion isn’t wasted. The officer’s testimony gets locked in on the record, which can be used to point out inconsistencies later at trial.
Frequently Asked Questions
What kind of evidence can be suppressed in a Georgia DUI case?
Almost any piece of evidence tied to your arrest can be challenged, including the traffic stop itself, field sobriety test results, breath or blood test results, and any statements you made to police. If officers broke a rule while gathering that evidence, a judge can exclude it from your case.
How long do I have to file a motion to suppress after a DUI arrest?
In superior court, you generally have 10 days after arraignment to file, though a judge can extend that. State and municipal courts each set their own calendars, so the deadline depends on where your case is being handled. You also have a separate 30 day window to fight the administrative suspension of your license, so both clocks start running fast after your arrest.
Can a DUI charge get dismissed if the stop was illegal?
Yes, this can happen. If a judge finds that police lacked reasonable suspicion to pull you over, any evidence gathered after that stop can be thrown out. Without a breath test result or officer observations to rely on, prosecutors sometimes have no choice but to dismiss or reduce the charge.
