Accused drunk driver stopped for speeding in early afternoon. Police officer speaks to driver about violation, obtains license and registration and then returns to cruiser to write ticket. Upon return to driver’s window officer detects an odor of alcohol for the first time, which leads to exit order, field sobriety tests and subsequent arrest. Inventory search of vehicle discloses open containers. Speed in excess of 30 M.P.H. over posted leads to Aggravated DWI Charge. Defense prepared to argue that police officer illegally expanded scope of initial speeding stop, which was concluded, when only observation of alleged impairment was an odor of alcohol. Aggravated DWI and DWI charges dismissed before trial.
