NH Police respond to scene of single car off road into snow bank. Elderly driver tells police he as forced off road by errant snow plow. Police do not note any signs of impairment while speaking with the driver and making arrangements for a tow truck. Several minutes later the driver approaches the officer conducting traffic control to complain about the cost of the tow. Only during this third conversation does the officer not an odor of alcohol and that the elderly driver walks with an obvious limp. When questioned the driver admits to having one vodka drink in a goblet sized glass one (1) hour earlier at a friend’s house. The officer requests that the driver stay on scene to complete field sobriety tests which he fails. Post arrest breath test results are .12 BrAC and .11 BrAC. Defense files and argues Motion to Suppress alleging Police did not have reasonable articulable suspicion to detain driver and insist that he participate in field sobriety tests under both article 19 of the New Hampshire Constitution and the Fourth Amendment of the United States Constitution. Defense Motion to Suppress granted, NH DWI charges dismissed.
