The people responsible for an automobile accident are those who are operating the involved vehicles at the time of the accident - unless the cause is mechanical failure or some other event outside the control or any of the operators. The person responsible for paying for the resulting damages may be the vehicle owners or the person who bought the vehicle insurance (usually, but not always, the same person). When operator negligence is involved, the operator may be responsible for paying the damages, even though the operator is not the insured person.
