Hi, I live in Los Angeles, California and I haven’t actually been arrested for DUI. But in case I will be charged for DUI and I get a lawyer, what knowledge should a lawyer have when it comes to different blood alcohol testing methods used in a DUI case?

If you get arrested for DUI in Los Angeles, California, you definitely have a choice of a breath, blood or urine test to find out your blood alcohol level. This is the reason why every DUI defense lawyer should have sufficient scientific knowledge in order to effectively cross-examine the state’s expert, as well as to present defense expert testimony. Mouth alcohol, absorption, interfering substances, peak and elimination of alcohol, chemistry and other scientific issues are extremely critical in representing a person accused of DUI.

Being knowledgeable on the various breath, blood and urine testing methods and their scientific principles is also required for the competent DUI defense lawyer. Every blood alcohol testing device has its own unique strengths and weaknesses. Those weaknesses should be explored in front of a jury in order to provide the defense with effective assistance of counsel. In several occasions, the chemical testing machines are neither properly operated nor calibrated and this can be attacked by a good DUI defense lawyer who has enough knowledge on the information about how chemical testing machines are being maintained.
