Breath and Blood Tests

Fairfax DUI Lawyer

A breath test or blood test will be a key part of any Fairfax DUI. To be considered "under the influence" a driver must have a blood alcohol concentration that is at .08% or greater or have normal abilities that are impaired due to alcohol or drugs. A breath or blood test will be the way that law enforcement will determine a driver's blood alcohol concentration and therefore offer the prosecuting attorney evidence to file DUI charges against the driver.

Fortunately, there are particular ways your Fairfax DUI attorney can work to challenge the results of a blood or breath test. This may include looking into the way the test was administered, whether the individual that administered the test was qualified to do so, and whether the breath test device was properly calibrated. Uncovering evidence of any error or violation of procedure may serve to turn a defendant's case around and help him or her to avoid a conviction.
