While the Breathalyzer test is among the most common way to determine an Illinois driver’s blood alcohol content, there are other methods available. For instance, a police officer could measure it through hair follicle or urine testing. It is also possible to do so through saliva and blood. Generally speaking, blood draws are done if an individual refuses to consent to a Breathalyzer test. It can also be conducted after an accident.

Although they are not perfect, Breathalyzer tests have been determined to be accurate enough to be entered into evidence in an impaired driving case. However, if there are flaws with the way the machine is designed or used, readings used to charge a person could be thrown out in court. It is important to note that any commercial device used by a consumer may not be accurate. Furthermore, readings from such a device are generally not allowed to be used as evidence.

Drivers may believe that there are tricks that they can use to get a favorable result on a Breathalyzer test. However, this is not true. In fact, some tactics such as ingesting mouthwash could have the effect of raising a person’s blood alcohol content. Furthermore, it is unlikely that ingesting onions or breath mints will have any impact on the results of a Breathalyzer test.

Those who are charged with drunk or impaired driving can turn to a DUI defense attorney for help. An attorney may work to have evidence suppressed or otherwise challenge it in court. For instance, if a sobriety test was conducted improperly, it could be possible to have the results thrown out.
