Through evidence, evidence such as direct testimony from eyewitnesses to the motor vehicle crash, to those that were involved in the crash. Also to demonstrative type of evidence such as photographs of the crash scene or of the vehicles involved, and often we hire accident reconstructionists that are experts in reconstructing an accident to help assist the jury in understanding who was at fault, or who was negligent in causing the motor vehicle crash. It’s all of the evidence that arises out of the event or out of the accident that assists us in ensuring that we can prove by the greater weight of the evidence that the other driver or other person was at fault or negligent in causing the crash.
