Many people believe that the number that a breathalyzer presents is always accurate. However, this is far from the truth. Multiple factors can impact a breathalyzer reading, and one of them is the machine itself.
Factors That Affect Breath Tests
There are numerous factors that can affect the accuracy of breathalyzer test results.
Examples include:
- The driver’s medical history
- The driver’s current medical conditions
- The driver’s recent burping or vomiting
- The driver’s recent use of products containing alcohols, like mouthwash
- The officer’s training on how to use the device
- The way the officer administered the test
A major factor that many people often forget is whether or not the device itself has been well maintained and calibrated according to standards.
Breathalyzer Calibration Standards
According to Utah law, breathalyzer calibration is the “manual setting of specific levels on a breathalyzer by a person trained to reset the device to ensure as accurate results as possible.”
Utah law also states that breathalyzers must be calibrated every 30 days or 300 uses. Failure to do so can lead to inaccurate readings.
Proving The Breathalyzer Was Uncalibrated
You may be wondering, even if the breathalyzer was not calibrated per the requirements, how can this be proven?
Breathalyzer data is recorded and stored by a third party, including calibration records. Your attorney will likely be able to subpoena these records. If the device records show the machine was not calibrated at the time of your breath test, you can question the accuracy of the results.
