A Waterbury man was arrested in Danbury Saturday morning for drunken driving after making an illegal left turn and striking another vehicle, police said. Elton Gardner, 54 of Meadowbrook Drive in Waterbury, refused to take a breathalyzer test, but failed a field sobriety test after the accident on Lake Street Extension, police said. Danbury police said both Gardner’s vehicle and that of the other victim were towed from the scene. Gardner is due in court on March 23.
