Can the results of Breathalyzer tests be trusted?

If you are pulled over by law enforcement and asked to take a Breathalyzer test, the result of that Breathalyzer test could mean the difference between being charged with a DUI and walking away with no consequences. Since such an emphasis is placed on the results of Breathalyzer tests, it is often assumed that they are highly accurate. However, this is not always the case.

The accuracy of Breathalyzer tests has been a topic of discussion for decades. However, a recent investigation by The New York Times has found that the use of Breathalyzer tests is leading to innocent drivers being charged with DUIs, and in some cases, it is allowing dangerous drivers to stay on the road. The following are some of the reasons why Breathalyzer tests can deliver inaccurate results.

Semiconductor sensor technology

Semiconductor sensors are often made with a tin-oxide material because it is inexpensive. However, this material can lead to false positives. They are believed to be sufficiently reliable, however, they can lead to inaccuracies that could lead to a wrongful DUI charge.

Environmental factors

Breathalyzer tests can be extremely sensitive to environmental factors, which can lead to frequent inaccuracies. Tests can be triggered by paint fumes, chemicals and varnishes.

Human error

Breathalyzer tests require manual operation. Therefore, if errors are made when operating the device, mistakes can be made. If you believe that a mistake was made when you took a Breathalyzer test, you may be able to highlight the impact of human error.

Faulty software

Breathalyzer tests run on software than can be faulty. All breath tests should be conducted multiple times to ensure that there are no discrepancies between results. If you noticed that there were significant discrepancies between the results measured on your breath tests, you may be successful when challenging your DUI charge.

Using Breathalyzer test inaccuracies as a DUI defense

If you are facing DUI charges, it is a good idea to consider whether Breathalyzer test inaccuracies could have led to your charges. There are many aspects of the test that you could bring into question when it comes to successfully defending yourself.

Make sure that you take swift action to begin forming your defense if you have been accused of driving under the influence of alcohol in South Carolina.
