After a traffic accident, the parties concerned shall report the case to the insurance company at the same time. If the other party is also a motor vehicle, the insurance company of the other party can jointly determine the loss of its own main vehicle. If the loss amount is large, we may also bear the loss, and the insurance companies of both parties will jointly determine the loss. After the damage is determined, both parties can carry out vehicle maintenance according to the amount of the damage, without the signature of the other party.

And if the other party doesn't have an insurance company and doesn't recognize the amount of car damage on its own side, the parties can ask the traffic police department to entrust the price part to fix the damage, and then the parties can carry out vehicle maintenance without the other party's signature. After the maintenance, if the other party refuses to pay compensation, the parties may bring a lawsuit to the court for compensation according to the responsibility identified by the traffic police and the appraisal conclusion of the price department.
