Who is at fault when your making a left Hand turn on a green light and a motorcycle hit you?

if you make a left turn and there is is a collision it is YOUR fault. unless it was a green left turn arrow. the vehicle making the left MUST use caution AND give the right of way to any other vehicles, as I said before unless you have a green left turn arrow

As a general rule across the U.S., anytime a motorcycle is involved in a crash with a non-motorcycle vehicle, the non-motorcycle driver will be found At Fault. (check the stats).
