Breath test devices, commonly used in New Jersey to measure blood alcohol content (BAC), can occasionally produce false positive results. Understanding these potential causes can help you challenge inaccurate readings.
Mouthwash residue
Breath test devices can detect residual alcohol from the recent consumption or use of mouthwash. It can lead to a falsely high BAC reading and DWI charges. Ensuring a sufficient waiting period after consuming or using mouthwash can help mitigate this issue.
Medical conditions
Certain medical conditions, such as diabetes, can cause the body to produce acetone, a compound that can be mistaken for alcohol by breath test devices. Individuals with such conditions may experience false positives if their breath is tested during a hypoglycemic episode.
Device calibration and maintenance
Improperly calibrated or poorly maintained breath test devices can yield inaccurate results. Regular calibration and maintenance can ensure accurate readings and minimize errors.
Environmental factors
Exposure to alcohol vapors can also lead to misunderstandings. Exposure to certain cleaning agents or industrial processes can also affect breath test results. Devices may pick up these vapors, causing a false positive reading.
User error
Incorrect use of the breath test device, such as following improper breath sampling techniques, can impact the accuracy of the results. Ensuring the device is used according to the manufacturer’s guidelines is necessary for reliable measurements.
If you suspect a false positive result on a breath test, you now know the reasons that could occur. Being armed with this information can help you if you decide to take legal action.
