Establishing fault in a multiple-vehicle accident depends on the amount and nature of the evidence that is gathered. The more evidence you can produce and the higher quality it is, the stronger your claim or argument will be. Desirable sources of evidence include:Reports from first responders: Police and emergency crews will collect information from all parties and create written crash reports.Electronic device records: Cell phones, onboard vehicle tracking devices, dashboard cameras, and traffic cameras can all provide evidence of whether a driver was texting or driving erratically at the time of a crash.Vehicle damage: The location of the damage on a car often indicates who is at fault.Video footage and photos: Pictures of the crash scene, injuries, road debris, and weather conditions can establish details of the situation.Black box data: Most newer model vehicles have Event Data Recorders (EDRs), which show the car’s speed and braking at the time of the accident.Witness statements: All drivers involved as well as pedestrians, car passengers, and drivers in the opposing lane of traffic may all give statements about what they witnessed.
