Challenging the Results of Intoxilyzer Breath Tests

If you were recently arrested for drunk driving and failed a breath test, you might believe that there's simply no way to avoid being convicted. It is understandable that you feel this way. But it is also not an accurate belief.

At the Rooney Law Firm, we have more than 30 years of experience helping people in Chico and throughout California to avoid jail, keep their drivers' licenses and protect their futures from the damaging consequences of a DUI conviction. We are confident in our ability to help you too — no matter how strong the breathalyzer evidence might look right now.

An Imperfect Way to Measure Blood-Alcohol Content

The Intoxilyzer 5000 breath test machines used by California law enforcement officers do not always provide accurate results. There are several reasons for this, not the least of which is the fact that California law only requires the machines to be accurate within 10 percent.

At this law firm, Intoxilyzer breath test results that are close enough simply aren't good enough — especially not in cases where a 10 percent difference in accuracy can mean all the difference in the world to our clients.

As your defense attorneys, we will carefully examine whether the Intoxilyzer breath test was performed accurately with properly maintained equipment and whether the officers had probable cause to stop you. As we move forward, we will also consider the use of experts, such as toxicologists, to sort through and challenge the evidence.
