1. How Breathalyzer Tests Work in Georgia
In Georgia DUI cases, law enforcement often uses a breathalyzer machine to estimate your blood alcohol concentration (BAC).
These devices measure alcohol in your breath and convert it into a BAC reading. In most cases:
- A BAC of 08% or higher is considered over the legal limit for drivers 21+
- Lower limits apply for commercial drivers and drivers under 21
Breath tests are commonly used in the Metro Atlanta area—including Cobb, Fulton, DeKalb, Clayton, and Gwinnett Counties—as well as Hall, Douglas, Cherokee, and Forsyth Counties, where DUI enforcement is strict.
2. Are Breath Tests Always Accurate?
No—breathalyzer tests are not perfect.
While they are widely used, their accuracy depends on:
- Proper maintenance and calibration of the machine
- Correct administration by the officer
- Environmental and physical factors
Even small errors can lead to inaccurate or inflated BAC readings.
Courts in Fulton, Cobb, and Gwinnett Counties regularly see DUI cases where breath test results are questioned or challenged.
3. Common Ways to Challenge a Breathalyzer
There are several legal defenses that may apply in a DUI case involving a breath test:
🔹 Improper Calibration or Maintenance
Breathalyzer machines must be:
- Regularly inspected
- Properly calibrated
If records show the device was not maintained correctly, the results may be unreliable.
🔹 Officer Error
Law enforcement must follow strict procedures when administering a breath test.
Issues may include:
- Failing to observe the driver before testing
- Improper use of the device
- Not following required protocols
Mistakes like these can weaken the prosecution’s case.
🔹 Medical Conditions
Certain conditions can affect breath test results, such as:
- Acid reflux (GERD)
- Diabetes
- Other medical or dietary factors
These can sometimes produce false high readings.
🔹 Mouth Alcohol or Contamination
Residual alcohol from:
- Mouthwash
- Recent drinks
- Certain substances
Can impact the test if proper waiting periods are not followed.
🔹 Rising Blood Alcohol Defense
Alcohol levels can continue to rise after driving. This means:
- Your BAC may have been below the legal limit while driving
- But higher by the time the test was administered
This timing issue can be critical in DUI defense.
4. What to Do If You Failed a Breath Test
Failing a breathalyzer does not mean your case is over.
🔹 Get Legal Help Immediately
An experienced DUI lawyer can:
- Review maintenance and calibration records
- Analyze how the test was conducted
- Challenge the accuracy of the results
- Identify other defenses in your case
🔹 Act Quickly
DUI cases involve strict deadlines, especially for:
- License suspension issues
- Evidence preservation
🔹 Avoid Assumptions
Many people believe a failed test guarantees conviction—but that’s not always true.
Whether your case is in Fulton County, Cobb County, Gwinnett County, or anywhere in the Metro Atlanta area, challenging the evidence early can improve your chances.
