Many people who are facing DUI charges wonder if there was something wrong with the breathalyzer device they used when they were pulled over and arrested. How likely is it that breathalyzers give false positive readings?
While breathalyzer testing is more accurate than other subjective field sobriety tests, breathalyzer tests can still be incorrect or inaccurate. If you believe that the breathalyzer test results that you gave prior to your DUI arrest are inaccurate, it is imperative to secure legal representation immediately.
When you are pulled over in Illinois, and the police officer has a reasonable suspicion that you are intoxicated behind the wheel, the officer can administer a breathalyzer test. A breathalyzer test is a chemical test that assesses how much alcohol vapor is on the breath of the individual taking the test. This data generally correlates to an individual’s blood alcohol concentration level.
Under Illinois’ Zero Tolerance law, 625 ILCS 5/11-501.8, any underaged driver who has a blood alcohol concentration reading of 0.01 or higher will lose his or her license and be arrested. Under Illinois DUI laws for individuals over the age of 21, 625 ILCS 5/11-501, drivers with a BAC of 0.08 are presumed to be driving while under the influence of alcohol.
Illinois is an implied consent state, meaning that by using the roads in Illinois a driver automatically consents to be subjected to chemical testing when suspected of driving under the influence of alcohol. Individuals do have a right to refuse a breathalyzer test, but there are steep consequences for refusal. For instance, when a person refuses to take a breathalyzer test, his or her driver’s license is automatically suspended in accordance with 625 ILCS 5/6-203.1.
Why Can Breathalyzer Test Results Be Incorrect?
There are a number of reasons why breathalyzer test results can be inaccurate. If one of the following scenarios applies to you and your breathalyzer test, you should consult with your DUI criminal defense lawyer to see if you can build a viable defense based on your situation. Breathalyzer test results could be inaccurate because:
- The breathalyzer device may be malfunctioning;
- Law enforcement improperly administered the test;
- Law enforcement failed to calibrate the breathalyzer device before it was used;
- You may have a health condition that makes you give a false reading on a breathalyzer test; or
- You consumed or used alcohol, but not of the type that could make you drunk or unable to operate a vehicle. Examples might include:
- Consuming cough medicines that contain high levels of alcohol;
- Wearing certain lip plumpers on your lips;
- Using certain vaping products (i.e., electronic cigarettes or e-cigs), which contain alcohol and can be so concentrated on the breath of a user that the user can produce a measurable reading on a breathalyzer; and
- Using certain mouthwash or breath sprays, which can artificially raise a person’s breath alcohol content.
