Legal Question in Traffic Law in Illinois

The basic rule in situations like these is whether the governmental unit responsible for this stretch of road had been on notice of the condition for enough time that they should have been out there salting it down, and then even if they had, it might not have been enough. Proving such things would be very difficult. If you are able to get your insurance company to cover the damages, however, and all you are stuck with is the deductible on the car damage, most likely it would be your insurance company deciding whether or not to attempt to seek liability from the governmental unit, which again is most unlikely, but as the insurance company would "subrogate" to your claim upon payment to you, it really would be their decision.
