I was in accident at a 4way intersection i was in the left lane at the light waiting to left turn with my left turn siginals on once i notice it was

Normally a vehicle in Maryland making a left turn on a solid green signal, must yield the right-of-way to all oncoming traffic.  I suggest that you speak with your insurance company to determine if you meet any of the exceptions that would instead make the other driver solely at fault or perhaps makes both of you at fault for the collision.  Good luck with this matter.
