How Accurate Are Breathalyzers?

When a cop suspects someone of driving under the influence, the most common device they will use to test for alcohol is a breathalyzer. Breathalyzers are designed to detect the level of alcohol in one’s bloodstream and provide police with an accurate BAC level. If a driver’s BAC is over the legal limit of .08, they will be arrested for a drunk driving offense.

Breathalyzers play a pivotal role when it comes to DUI charges. Law enforcement depends on these devices to function properly, but the truth is that breathalyzers can malfunction in many ways. If you have been charged with a DUI, chances are that a breathalyzer was a key factor in your arrest. Breathalyzer tests are not always reliable, therefore your arrest may be unwarranted. One of the ways to have DUI charge lessened or dropped altogether is to contest the accuracy of a breathalyzer. DUI cases involving breathalyzer functionality can be complex, so it is important to have a strong attorney fighting on your side. The lawyers at Hart Powell, S.C. are prepared to help you through your legal battle.

Common Breathalyzer Problems

Because breathalyzer test results hold such a heavy weight in legal cases, they’re expected to provide accurate numbers. However, this is not always the case.

  • The machine was improperly calibrated
  • The test was improperly administered
  • Other chemicals were present that influenced the results
  • Machine was damaged in any way

A DUI charge can have detrimental effects on an individual’s personal and professional life, so if you, for any reason, believe your breathalyzer results were inaccurate, it is important to find a strong attorney.
