Police said they are investigating after video emerged online appearing to show a male toss a traffic sign onto live traffic along a highway in Oakville, Ont.

The video appears to show a person throw an orange sign from the Winston Churchill Boulevard overpass onto the Queen Elizabeth Way.

“The sign was thrown down onto the live, eastbound lanes of the highway,” investigators with Halton Regional Police Service said on Friday.

Police say they do not know when the incident occurred.

“The behaviour depicted in this video is extremely dangerous and criminal in nature.”

Images on Google Maps from Winston Churchill Boulevard near the QEW show a “right lane exit” sign, which appears similar to the one thrown in the video.
