There is such a thing as "impeding the flow of traffic", or something like that. And Po-po can decide to fault the other person. I know this is "dated" information, but years ago, someone stopped on 575 (or maybe it was 75), north of us, because they said the fog confused them. Someone else came along and rear ended them, but the person who stopped on the interstate was faulted. It's rare, but it happens. Keep pushing the fact that the driver admitted to stopping in the middle of the road. If it caused a hazard, or impeded the normal flow of traffic, they might be faulted.
