I was on the scene of a motorcycle-car collision recently. There were three other officers and everybody seemed to have a different idea regarding liability. Four lane road, two in each direction. There is a big hole in the outside lane going Westbound, with warning barricades surrounding it, but not advising that the lane is closed. There is not enough space for a car to get by, but plenty of room for a motorcycle. There are multiple cars in the inside lane (they have no choice) and the motorcycle in the inside of the outside lane. Right after the hole there is a three way intersection with a road going Northbound. One of the cars in the inside lane slows down, then turns right to go N/B on that road and is struck by the motorcycle. The opinions regarding liability seem to revolve around whether the lane was closed, or merely partially blocked, and whether the motorcyclist had the right to proceed in his lane Thusly: Option 1 Motorcyclist is at fault, as he shoiuldn't have been there. Option 2 The car driver is at fault, because she should have looked to see if she could turn safely. Option 3 The city is at fault, because if they had officially closed the lane, the accident could not have happened What is your opinion or better yet if anyone has relevant case law that would be even better. BTW this happened in TN.
