Knowing who is at fault in a multi-car collision starts with understanding fault in general. Assigning responsibility to a party requires evidence of negligence. That entails:
Duty of care: All drivers are required to operate their vehicles responsibly.
Breach of duty: A driver did not operate their vehicle in a reasonable manner.
Causation: The failure to correctly operate the vehicle caused an accident.
Damages: The injuries caused by that accident are grounds for compensation.
Accidents involving multiple vehicles can typically be traced to an act of negligence, like speeding. However, that reckless action is one event in the chain—and untangling the threads can seem impossible without help from a lawyer.
