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.
