A missing teenager from North Carolina used a hand signal she learned on TikTok to alert a passing car that she was in trouble, leading to her rescue. The 16-year-old girl flashed the gesture, which caught the attention of a good Samaritan, who then called 911 as they traveled down the highway in Kentucky. The teen apparently learned the hand signal -putting up your palm, tucking your thumb in and covering it with your fingers – on TikTok, from a woman using it as her abuser stood in the background.
