Who is at fault is a moving vehicle hits a non moving vehicle that is legally parked on the street?
Of course it seems like the moving vehicle is. They should have left a note if they were an individual with morals and who would'nt like that to be done to them.


ADDITIONAL INFO: Though each accident is handled on a case by case basis, generally the operator of the moving vehicle would be at fault, however instances where a vehicle is illegally parked or grossly impeding traffic may warrant further investigation. In such cases it would be possible to make a case for the illegally parked vehicle be at fault. In such a case of an illegally parked vehicle the owner of the vehicle, even if not deemed at fault, would more than likely at least receive a citation.

If such action occurred, then it would be easier for the operator of the moving vehicle, even though they were determined to be at fault, to make a case that if the illegally parked vehicle were not illegally parked in the first place then the accident would have never happened.
