Ms. Kennedy is the daughter of the late Sen. Robert F. Kennedy and niece of the late President John F. Kennedy.

Police say she was arrested Friday after her car struck a tractor-trailer on an interstate north of New York City and she took an exit off it. They say an investigation found she was impaired by drugs.

A spokesman for Ms. Kennedy says breath, blood and urine tests revealed no drugs or alcohol in her system. Her lawyer says she’ll plead not guilty.

Ms. Kennedy’s sister-in-law, Mary Kennedy, hanged herself in May. Her brother, Douglas Kennedy, is fighting charges stemming from his attempt to take his newborn son from a maternity ward.
