In a motion filed Friday, attorney Gerald Lefcourt also says the only harm done was to Kennedy's pride and her good name.
Kennedy, ex-wife of Gov. Andrew Cuomo, was arrested in July after police said her Lexus swerved into a tractor-trailer on Interstate 684 near her Bedford home.
Tests found a small amount of a sleeping drug in Kennedy's blood. She said she believes she accidentally took a sleeping pill instead of thyroid medication.
In the motion, she says she would never drive after knowingly taking the drug.
A Westchester County district attorney's spokesman would not comment on the motion.
