Passengers involved in accidents must know which party is at-fault. The passenger in the car that caused the accident can file a claim against the driver’s insurance and possibly sue the driver for negligence. If the passenger is in a car that did not cause the accident, that passenger can file a claim against the other driver’s insurance.nnPassengers may, however, have a part to play in an accident. If a passenger is found to have contributed to causing the accident, their claim could be denied. As mentioned, distracted driving includes interacting with passengers. A passenger who causes an accident could be sued by the driver of the vehicle and anyone else who was injured in the crash.
