Police stop 68 year old driver for speeding and detect odor of alcohol, slurred speech and red/glassy eyes. Driver submits to field sobriety tests which police allege he failed. Post arrest breath test of .10 BAC excluded by defense due to lack of certification of breath test equipment. Police admit that field sobriety tests are not necessarily valid for any person over 65 years of age and there was no erratic operation of vehicle beyond speeding violation. Not guilty verdict following trial.
