Tracey's story proved to Yvonne that accidents do happen...even if you've only had a drink or two. After watching the show, Yvonne says she made a promise to her daughter never to drink and drive again.
Yvonne wants to thank Tracey for sharing her "Aha!" moment with millions of viewers. "It was so brave," Yvonne tells Tracey. "It made it possible for me to recognize my weaknesses and what I need to change."
