I will try to explain this the best I can without a diagram. Imagine a upside down "T" intersection, someone parks on the curb of the leg of the "T"(right hand side) at at the intersection clearly on his side where one would normally park. Another car is turning left onto the same street as the parkedar is reversing, The approaching car may or may not have gauged the turn based on the fcat the car is reversing or clearly just didnt turn enough. The front passenger corner of the approaching car hits the rear drivers side bumper of the reversing car. Whos in the wrong?
