Do you know this hand gesture? It could save your life.

A 16-year-old-teen used this sign she learned on Tik Tok to signal for help to passing motorists. She had been reported missing by her parents two days earlier. An alert motorist in Kentucky called 911 to report seeing a ‘girl in distress in a vehicle on the interstate.’

“The complainant was behind the vehicle and noticed a female passenger in the vehicle making hand gestures that are known on the social media platform ‘Tik Tok’ to represent violence at home — I need help — domestic violence,” reads the statement posted on Friday by the Laurel County Sheriff’s Office.
The good samaritan followed the car for seven miles until the police caught up with him and he was quickly arrested.

Watch the video so you’ll know how to recognize when someone is signaling for help, or you need to use it yourself.

Someone using the signal holds their hand up with their palm facing out, then tucks their thumb into their hand and then closes their fingers to trap thumb.
