In Georgia, like in most other states, many DUI cases rely on evidence from breath testing machines. While prosecutors and police tout these machines as accurate and their readings to be reliable, the truth of the matter is these machine are inaccurate and based on faulty technology.
First, let’s take a look at the science behind these breath testing machines. DUI breath testing machines indirectly measure the amount of ethanol in a breath sample. Infrared beams are passed through and they bounce off the molecules in the breath sample. The machine then analyzes the patterns made by the reflecting beams. If the pattern matches the pattern for ethanol, it is counted and reported.
The problem with this method is there are many molecules found in nature which are similar in structure to and produce the same pattern as ethanol. Any substance in the body with these molecules will produce a false reading. These substances include:
- Inhalers used by asthma patients
- Exposure to paint thinner
- Cough Medications
- and even plain white bread!
As you can see, this is problematic and can cause false readings in many cases. False readings lead to false arrests and false arrests lead to false convictions.
This is why it is highly advised that you have your case reviewed by an attorney who is trained in DUI breath testing issues.
