Are DWI Breath Tests Always Accurate?

When it comes to DWI breath tests, accuracy can vary depending on the type of test administered and how well the test was performed.

Breathalyzer tests, the most commonly used form, measure a person's blood alcohol concentration (BAC) by analyzing their exhaled breath. Generally, these tests are considered to be fairly accurate and reliable when administered correctly. However, it is important to note that the accuracy of the test can be influenced by external factors such as temperature and humidity, as well as when a person had their last alcoholic drink.

Police Breathalyzers May Not Always Be Accurate

Portable breathalyzer devices are often used by police officers when they suspect a driver of operating while impaired (OWI) or driving while under the influence (DWI). These devices measure alcohol in a person's breath and are used to determine a person's estimated blood alcohol level (BAC).

While these devices are often accurate, there are certain cases where their results may not be reliable. For example, some people have falsely high BAC readings due to medical conditions like acid reflux or diabetes. Additionally, the accuracy of portable breathalyzer devices can be affected by environmental factors, such as temperature and humidity. Furthermore, improper maintenance or calibration of these devices can lead to inaccurate results.

It's important to note that a breath test is only one way of measuring BAC. In many cases, blood tests are more accurate than breath tests because they measure the actual amount of alcohol in the bloodstream. However, blood tests are invasive and require more time and resources to administer.

Arrested for DWI? Contact an Attorney for Help.

Overall, the accuracy of DWI breath tests depends on a variety of factors. While these devices can provide an estimate of your BAC, they may not always be accurate. If you're facing charges related to operating while impaired or driving under the influence, make sure that your rights are protected by consulting with an experienced criminal defense attorney. They will be able to determine what evidence is admissible in court and help you present a strong legal defense.

It's important to remember that no matter the result of a breath test, you have rights and should not be judged until all evidence is presented in court. With the assistance of an experienced attorney, you can mount a strong defense and protect your future.
