Relief fund, also known as social relief fund for road traffic accidents, is a social security system established in China to solve the problem of compensation for road traffic accident victims. Its main purpose is that in traffic accidents, when the victim can't get compensation from the person responsible for the traffic accident or the insurance company in time, he can get temporary economic assistance through the rescue fund.

The rescue fund is not a substitute for the compensation of the person responsible for the traffic accident, but an advance payment when the person responsible fails to perform the compensation obligation. Therefore, when the rescue fund advances, the person responsible for the traffic accident still needs to bear the liability for compensation and repay the amount advanced by the rescue fund.
