My first winter in Wisconsin I was driving during a bad snow storm on a road I wasn't familiar with (bad combo yeah). The snow had fallen enough at that point that the road wasn't visible any longer, and the snow had filled the shoulders of the road. At some point I unfortunately found the edge of the shoulder, and due to the slipperiness, my car was thrown around in a 180, and I slid down the hill into a Utility pole. The only damage ended up being to my car (the pole anchor ended up turning my trunk into a crumple zone), and the plastic broken off the pole anchor. A police car rolled by about 5 minutes after my accident and found me, filled a report, and got a tow truck that pulled me off the anchor (my rear bumper's plastics were cracked and holding on to it), where I proceeded about my day (I needed new tail lights and a new trunk, but the car was perfectly fine, still driving it today).
Anyways, the point is that either way, 6 months later, in the summer, my Insurance company calls me and tells me that the City I lived in had sent them a $5,000 bill for pole inspection. They said not to worry about any of it, because it was far too late to be sending any bills, and there was nothing in the police report justifying that cost (the policeman even noted in his report that there didn't appear to be any damage to the pole aside from the plastic covering the pole anchor).
Anyways, my only point is that if the police were involved, chances are your insurance will eventually be notified and asked to foot the bill.
