WHITE PLAINS — After nearly 20 months of buildup, the misdemeanor trial of Kerry Kennedy ended on Friday in a breakneck blur, as jurors took one hour to find her not guilty of driving under the influence of a drug.
The five-day trial, which featured a riveting turn on the witness stand by Ms. Kennedy, 54, was centered on an act that neither she nor prosecutors dispute: On July 13, 2012, she drove her Lexus S.U.V. erratically after swallowing Zolpidem, a generic form of the sleep medication Ambien. She sideswiped a tractor-trailer on a highway in Westchester County before she was found, slumped over her steering wheel, her car stalled on a local road.
Ms. Kennedy has maintained that she took the pill accidentally, mistaking it for medication she took for a thyroid condition. She testified on Wednesday that she did not realize her mistake until well after the accident.
