Jomsap Saenmuangkhot, who lost her job as teacher, submitted a request for a fresh trial after serving a jail term over the death of a cyclist in the accident.
Jomsap has maintained she was innocent despite her conviction by the Supreme Court.
Her request for a fresh trial was initially accepted because a man had come forward to claim responsibility for the accident.
Yesterday, the Supreme Court ruled that there was no fresh evidence to warrant a fresh trial.
