A communication module may receive communications from a vehicle. A collision detection module may determine that a collision has occurred at a vehicle based on one or more of the communications received from a vehicle. A participant identification module may identify one or more participants involved in the collision based on one or more communications received from the vehicle. A fault determination module may identify one of the participants as the at-fault participant based on a comparison of a fault determination ruleset to vehicle telematics data included in one or more of the communications received from the vehicle. A claims processing module may determine whether to file an insurance claim associated with one of the participants based on the estimated repair cost.
