A 79-year-old Long Island woman was killed when she was hit by a car driven by her husband, police said Tuesday.

Nancy Richard was on her way home after walking her grandchild to the bus stop around 7:30 a.m. Monday when her husband slammed into her with a 2015 Mercedes while backing out of the driveway of their Fort Salonga home, Suffolk County cops said.

She was taken to Huntington Hospital, where she was pronounced dead, cops said.

Her husband, Peter Richard, 83, was not charged, police said.
