Driver stopped on highway for expired registration and failing to signal lane change. Officer notes glassy eyes and an odor of alcohol emanating from driver’s breath. Driver admits to drinking a few beers and is arrested following field sobriety tests. He refuses post arrest breath test because he doesn’t “trust the machine.”  Officer admits on cross exam that driver disclosed his prior leg disability and walked with a cane which was in the truck at time of stop. Open container found during inventory search excluded as evidence at trial because of missing witness that conducted search prior to tow. Not Guilty verdict on DWI Charge following trial.
