Following your accident, make sure the police are called to the scene of the accident. The responding officer will conduct an investigation, which generally includes interviewing all drivers involved in the accident and any witnesses to it.The responding officer will generally also record and document any physical evidence at the scene, like skid marks and vehicle damage. The insurance companies for the drivers involved in the accident will conduct their own investigation, as will your attorney. Initially, it will be up to the other driver’s insurance company to accept or deny fault for the accident.Should your claim be denied by the other driver’s insurance company, it may become necessary for you to file a lawsuit to prove liability and recover for your damages. With the passage of time, it becomes more difficult to gather necessary evidence and information to determine fault. That is why it is important to consult with an experienced auto accident attorney right away after a crash.
