Ways a Breathalyzer Can Be Wrong
26/01/2024

Every year, thousands of people face serious DUI charges, and some may even get a positive breathalyzer result despite not drinking. At Ticket Shield, our legal team has encountered cases where individuals feel helpless against law enforcement officials. This guide sheds light on the most common reasons for breathalyzer inaccuracies and how understanding them can help challenge false positive results.
1. Poor Breathalyzer Calibration:
Breathalyzer accuracy is crucial for DUI charges. A poorly calibrated machine may misinterpret alcohol levels, leading to false results. Regular calibration is essential, and an outdated machine could be grounds for challenging the validity of the evidence.
2. Bad Test Solutions:
Contrary to common belief, breathalyzers don’t directly detect recent alcohol consumption. They rely on chemical reactions between breathalyzer solutions and alcohol. Incorrect solutions, homemade mixtures, or the use of expired solutions can result in false positives, challenging the reliability of the test.
3. Tests Wrongly Modified:
Breathalyzers are delicate instruments, and unauthorized modifications by law enforcement officers can occur. Incorrect adjustments, such as turning off temperature measurement, may lead to inaccurate results, raising questions about the machine’s integrity.
4. Programming Errors:
Breathalyzers operate with complex computer systems dependent on accurate software. Subtle programming errors, often hard to detect, can produce false-positive results. Software bugs may compromise the reliability of the breathalyzer output.
5. Porous Test Methodology:
Even under ideal circumstances, breathalyzer tests can be unreliable. Incorrect instructions from law enforcement officers on how to take the test may result in false positives or negatives. Accurate and consistent instructions are crucial for obtaining valid results.
6. Medical Conditions:
Certain medical conditions, like diabetes, can lead to false breathalyzer results. Individuals with diabetes may have higher blood alcohol content readings than actual consumption. Using more sophisticated technology that accommodates medical conditions is essential for accurate testing.
7. Other Chemicals:
Breathalyzers are sensitive to chemicals present in the air, causing inaccuracies. Paint fumes, gasoline, or even mouthwash can influence the results. A skilled attorney can highlight the impact of environmental factors, leading to a more accurate understanding of the breathalyzer’s limitations.
