When handling a traffic accident, the public security organ shall, after finding out the cause of the traffic accident, determining the responsibility for the traffic accident and determining the loss of the traffic accident, convene the parties and relevant personnel to mediate the damage. The mediation period for damages is thirty days, and the public security organ may extend it for fifteen days when it deems it necessary. For injuries caused by traffic accidents, mediation shall be started from the date of the end of treatment or disability; If a traffic accident causes death, mediation shall begin from the date when the time for handling the funeral ends; If a traffic accident only causes property losses, mediation shall begin from the date of determining the losses. If an agreement is reached through mediation, the public security organ shall make a conciliation statement, which shall be signed by the parties concerned, relevant personnel and the mediator and take effect after being sealed by the public security organ. The public security organ shall send the conciliation statement to the parties and relevant personnel respectively. If no agreement is reached at the expiration of the mediation period, the public security organ shall make a mediation conclusion, which shall be signed by the mediator and stamped with the seal of the public security organ, and sent to the parties and relevant personnel respectively. If the mediation fails to reach an agreement or any party fails to perform after the mediation book comes into effect, the public security organ will no longer mediate, and the parties may bring a civil lawsuit to the people's court.
