A Fairfield man was charged early Friday with operating a vehicle under the influence of drugs or alcohol after an officer observed him making an improper turn on the Sherwood Island connector, police said.

John Miller, 55, of Old Stratfield Road in Fairfield, was pulled over after crossing the yellow double traffic line while making the turn.

Miller failed field sobriety tests, police said.

He was released on $500 and is scheduled to appear Aug. 26 in Norwalk Superior Court.
