Your DUI defense lawyer might be able to make valid legal defenses that could put the breath test examination into question and ultimately best your DUI case. Let’s review the various common methods below on how to challenge results of a breathalyzer exam.
Showing that Breathalyzers are not Reliable
It’s typically accepted by experts who testify in DUI cases that the breath test machine used by police are not always accurate. These machines have an “error rate,” which means in a close case, this could be used by a lawyer to beat your case or at least used a a tool to negotiate with the prosecutor for favorable plea bargain. There have been published articles showing the breathalyzer machines are not always reliable.
In fact, some scientists have concluded that breathalyzers fail the legitimacy test. An experienced Los Angeles DUI lawyer can challenge the breathalyzer results by showing the level of inaccurate results, meaning they simply lack reliability.
It should be noted that the DUI cases having the best chance of a favorable outcome using this type of challenge are the cases where the reading on the DUI breath test machine are close to the legal limit and when you were able to pass some field sobriety test.
When the DUI Breath Test was Administered
Another method to challenge the DUI breath test results involves when the breath test was actually administered in relation to when the you were observed by police driving the vehicle. The primary factor in this challenge is not what your blood alcohol level was the time the breathalyzer exam was taken.
Rather, it’s what your blood alcohol level was at the exact time your were driving a vehicle. This important question is relevant in finding you guilty of drunk driving. Clearly, the more time that has elapsed from the exact moment your DUI breath test was taken, the more difficult it becomes for the prosecutor to prove your actual blood alcohol level at the time you were driving.
It’s important to note the breathalyzer exams are administered by arresting police officers, who were trained to give these exams. It’s may be possible to argue the officer may have given you the breath test incorrectly or lacked adequate training. We could challenge the results by showing a lack of training can produce inaccurate results. We could also argue that the breathalyzer was not properly calibrated and the results were inaccurate.
Challenge the Breathalyzer Test was an Illegal Search
Police officers are legally required to follow procedures when conducting a traffic stop. In other words, they must have reasonable suspicion to pull you over on a traffic stop, meaning they have to have probable cause that you were driving under the influence before they can administer a breathalyzer. If we can show the police officer didn’t properly demonstrate both, the breathalyzer exam might be considered an illegal search.
