ST. LOUIS, Mo. (WCMH) – Video from a Missouri freeway shows two people ‘twerking’ on top of a moving vehicle.

It happened Monday during rush hour in St. Louis. Video shows two people dancing on top of a Suburban. Another person is halfway out a window recording everything.

The woman who recorded the video told KSDK she did not call police, but hoped posting the video to social media would lead someone to recognize the people.

Police call this kind of behavior a safety hazard.

“They could fall off of the car and cause other drivers to wreck. It’s a dangerous situation for themselves and other drivers! They could fall off and create a fatal accident. We do not encourage anyone to try anything like this ever. You are supposed to be in your car when you drive,” A spokesperson said.

Police said the people in and on the vehicle could be cited for several things, including riding on the exterior of a motor vehicle, not wearing a seat belt, failing to maintain minimum speed and failure to display a license plate.
