Tow truck operator loses towed vehicle due to hitch failure causing collision with oncoming vehicle. Responding EMT tells police that he smells alcohol on tow truck driver’s breath. Officer alleges that client failed three standardized field sobriety tests and then submitted to a breathalyzer test with a reading of .10. Defense argues that client’s performance on the field sobriety tests is adversely affected by the stress of the accident and police presence. Government witnesses fail to explain how breath test results convert to illegal blood alcohol content as required by drunk driving statute. Not Guilty verdict following trial.
