How to Defend against a DUI Charge in Arizona: 5 Ways Blood Tests Can Be Inaccurate
In Arizona, drivers may be charged with a DUI if their blood alcohol content is 0.08% or higher. Blood tests are widely accepted as being the most accurate way of determining blood alcohol concentration in drivers suspected of DUIs and are often the only objective evidence of a defendant’s guilt, making the validity of the test a central question in a DUI trial.
According to Stanford University, the effects of BAC levels can vary from person to person, male or female, slender or heavier; even medication can play a significant role on the blood alcohol readings. Stanford has published a BAC Graph showing the levels of blood alcohol.
Contrary to popular belief, blood tests are not always conclusive in proving that a driver’s blood alcohol content was above the legal limit. As explained below, many factors affect the accuracy of blood test results.
If your case involved the taking of blood or urine during your DUI arrest, you will need to wait and see if your BAC results come back at a reading of .08% or greater. This process can take between one (1) and six (6) months for your results to return. In the event your BAC readings are above a .08% the officer will send a suspension of driving privileges to the Arizona MVD office. You will then be notified with a “Corrective Action Notice” (i.e., notice of suspension). As soon as you receive this from the DMV, speak to our certified Phoenix DUI Specialist immediately so we can start the DUI Defense process and request a hearing on your behalf. This hearing request needs to be done within fifteen (15) days of the date of that suspension notice.
