BLOOD-ALCOHOL LEVELS
The results of the breath, blood or urine test will have a significant impact on the charges brought and the possible sentences. The so-called "per se" offense (driving over .08%) is defined by the blood alcohol level; the "DUI" offense (driving under the influence) is partially proven with a rebuttable presumption of intoxication if the result is over .08%.
It is important to realize that the DUI laws relate to the blood-alcohol level AT THE TIME OF DRIVING — not at the time of the test; there may be a significant difference, not to mention difficulties of proof. It is also important to understand that tests — particularly breath tests — are unreliable and susceptible to attack by an attorney who is knowledgeable in the science of Blood-Alcohol analysis.
