Police receive report of erratic operation and locate car matching description following it for period of time observing marked lanes violations. Officer notes driver’s eyes are red and glassy, speech is slurred and strong odor of alcohol. Client is arrested following field sobriety tests and submits to post arrest breath test of .13 BAC. Defense presents expert witness to challenge accuracy of breath test during active “absorption phase” of alcohol metabolism and focuses on operation of vehicle during time police followed vehicle. Further defense argues field sobriety testing results were reasonable given time and location of stop. Not guilty verdict following trial.
