In a car accident case, liability may be determined by different entities. Being the first to arrive in an accident scene, the police are often responsible for determining fault in most car crashes. They often assess the accident scene, talk to witnesses, and establish who committed a traffic offence. The insurance companies also determine fault, usually with the help of adjusters who investigate the accident. In other instances, the courts may sometimes establish fault through formal legal proceedings which often evaluate the evidence presented by both parties.
