DeKalb County DUI Breathalyzers
A breathalyzer is a device that is used to measure one’s blood alcohol content. These devices are commonly used by law enforcement at DUI stops to determine whether a person is under the influence of alcohol or not. An individual who is driving with a blood alcohol content of 0.08% or more is considered under the influence.

Are Breathalyzers Considered Reliable?
Breathalyzers are considered reliable instruments by the government, scientists, and police officers. However, as with most machines, the more the machine is used, the less accurate it is. When a breathalyzer is used a significant number of times, it comes out of alignment and is susceptible to error. Also, breathalyzers are only as accurate the person operating it. The device may be well-aligned but the person using it to administer a breath test may not be trained properly, which can lead to skewed results.
Breath testing is quick and relatively easy. While it has a level of reliability and accuracy, that does not mean that every resulting number is representative of an individual’s BAC at the time they blew into the breathalyzer machine.
A common misconception about DUI breathalyzers in DeKalb County is that they are accurate and reliable. A person may believe that if they have a breath test, there is no way to successfully overcome that piece of evidence because the machine never makes mistakes. However, that is not true.
False Positive or Inaccurate Breathalyzer Results
There are several reasons why a machine is not as reliable as the government may claim. A breathalyzer test could result in a false positive or an inaccurately high BAC score when the breathalyzer machine detects alcohol in someone’s mouth and not the alcohol in their deep lungs. Also, the machine may not be working properly. It could be detecting alcohol in the air or processing the breath sample incorrectly. There is a chance that the machine was not taken out of service for routine calibration and maintenance. Belching or upchucking into the mouth could introduce alcohol into the oral cavity that may give a false positive.
In spite of the issues with breathalyzer machines, government experts rely on them because they are quick, easy, and inexpensive. For less than $10,000, a breathalyzer machine could test every individual arrested for DUI in the jurisdiction.
Calibrating Breathalyzers in DeKalb County
In DeKalb County, breathalyzer machines must be certified and inspected on a quarterly basis. Every 90 days, the machine is inspected to make sure it is operating correctly. One of the first things a seasoned lawyer investigates is whether or not a machine is being inspected on a quarterly basis and looks at the maintenance and calibration records.
Challenging Breathalyzer Results
It is possible to challenge erroneous DeKalb County DUI breathalyzer test results in court. The results could be suppressed when there is an issue with the breath testing device, the operator, or the maintenance and inspection of the machine. These are all grounds to potentially exclude the results of the breath test. Every experienced lawyer who fights these cases challenges the admissibility and the foundation of the evidence. They ensure the testing was done within accordance with the police officer’s approved training.
