Because the responsible person is the direct cause of the accident, he should bear the corresponding economic compensation responsibility. The purpose of highway fund assistance is to help victims get timely treatment and reduce their family financial burden, so the responsible person needs to bear the corresponding repayment responsibility. If the responsible person has no insurance or cannot bear the repayment responsibility, then the rescue fund management institution will take other measures to recover. Therefore, the person responsible for repaying road fund assistance is generally the person responsible for road traffic accidents.
