Who decides who is at fault for my accident injury case?
Circumstantial evidence like skidmarks is used, and direct evidence from witness statements usually is how we do it. In motor vehicle collisions, assuming you made a police report, that can be helpful in determining fault. Sometimes there may be pictures from security cameras. It really depends on each unique case presented. In all events, you must be vigilant and get license plates, drivers license information and descriptions of parties. Call the police, take pictures with your cell phone camera. Get witness names and their contact info too.
