In a 99-page motion filed in North Castle Town Court, Kennedy and her lawyer also recount her work for social justice and include a large file of glowing letters from friends and relatives.
Kennedy is the ex-wife of Gov. Andrew Cuomo, the daughter of Sen. Robert F. Kennedy and the niece of President John Kennedy.
She was arrested July 13 after police said her Lexus swerved into a tractor-trailer on Interstate 684 in North Castle, near her Bedford home. Police found her on an exit ramp and reported she failed sobriety tests and was slurring her speech.
Tests found a small amount of the sleeping drug zolpidem in Kennedy's blood. She said she believes she accidentally took a sleeping pill instead of her daily thyroid medication.
In the motion, she said the two bottles were side by side and "are virtually identical in size, shape and appearance."
