Had an interesting call today. A semi trailer was being towed by a moving company - not pulled by a tractor - but pulled by a "tow truck" rolled over into a utility pole. The rig was being pulled around the turn of an intersection (E/B to N/B) and the inertia toppled the trailer. No one got hurt. The box came off it's chassis. COMED had to cut the power to the power lines so that we could move 3 vehicles with the power line draping over them. They crained the trailer back onto it's chasis, secured it and pulled it away. Crazy call.
