I Got Into A Car Accident Due To Someone Else Cutting Another Driver Off. Can It Be Considered My Fault? 
Honestly , this one sounds like it is going to be well investigated . It semms as if you were saying that the driver who was cut off swerved into the lane you already occupied . If that account can be substantiated , then it may be that the other driver might be at least partially liable . The best thing to do is to talk to your Insurance Professional about the terms and conditions of your policy . Further , let the Claims Professionals who are trained to investigate these matters complete their task .
