If you or a loved one is arrested for DUI, you should consider hiring a lawyer that knows the ropes. This DUI law firm provides exceptional service and quality representation. That is why I recommend this LosAngeles DUI Attorney. A conviction of a DUI will often lead to much higher insurance rates as well as the possibility of getting your insurance canceled. A good LA DUI Lawyer will thoroughly examine all the evidence. Its important to note that if it involves a breath test, you should always review the accuracy and maintenance logs and other evidence. If it is a blood test, you should always retest the blood sample to see if there was a adequate preservative in the blood vial. If there is an insufficient preservative, you could possibly get fermentation which results in a artificially high and false blood alcohol level. Many County Sheriff Crime laboratories use only 20 mg of sodium fluoride in a 10 ml blood tube. This generally results in .2% sodium fluoride in the blood vial.
