We already knew from thorough investigation that immediately prior to the accident, Support either the driver of the first vehicle changed lanes without signaling or the driver of the second vehicle was driving with excessive speed. ██████ ██ █████ ███████ █████ ████ █ ██████ ██████ ███ ███ █████████ █████████ ███ ███████ ████████ ███ ██████ ████ ███ █████ █████████ ████ ██████ ███ ███ ███ ██████ ███ ██████ ██ ████ ███████ ██████ ██ ██████ ███████ ██████ ██ ███ ██████ ██ ███ ██████ ███████ ██ ███ ██████ ███ ███ █████████
The author concludes that the driver of the second vehicle isn’t liable for the accident. This is because one of the two drivers involved certainly broke the rules of the road. And further, the first vehicle didn’t signal before changing lanes, which is sufficient to make that driver liable for the accident.
The author assumes that if one driver is liable, then the other is not liable; in other words, that the two drivers can't both be liable. This includes assuming that the second vehicle wasn’t being driven in excess of the speed limit, which is also sufficient for liability.
