The footage, uploaded by firefighters and timestamped just after 9 a.m., appears to show the southbound trailer jackknife while negotiating a snowy curve.
The trailer is seen sliding through the intersection with Washington Street and clipping a pedestrian crosswalk signal before toppling a flag pole and a lamppost in front of Shenandoah Ambulance.
Daily Voice has reached out to Shenandoah Borough police for more details.
