MA Driver stopped by police because the plate attached to his girlfriend’s car did not match registration information on file with NH DMV.  Once stopped it is determined that clerical error at DMV led to incorrect registration information.  Officer notes “overwhelming” odor of alcohol coming from driver, who admits to drinking earlier in Boston.  Driver will not consent to field sobriety testing, claiming he is fine to drive and the tests are unnecessary.  Only when ordered from car does officer note glassy and red eyes.  No other indicators of impairment present. Driver is arrested after continuing to refuse field sobriety tests, and he does not consent to blood/breath test post arrest.  DWI charge dismissed prior to trial and Administrative License Suspension also vacated at DMV for lack of evidence of impairment.
