Protection of victims' rights and interests: As a supplementary protection mechanism, road rescue fund can provide necessary medical expenses and life assistance to victims when the perpetrators escape or have insufficient compensation capacity.

Improve the efficiency of social assistance: the establishment of road assistance fund makes the assistance to traffic accident victims more rapid and effective, and avoids the situation that the victim's condition deteriorates or dies due to untimely assistance.

Rescue efficiency: Due to administrative procedures and other reasons, the distribution and use of rescue funds are not timely enough, which affects the rescue effect.

Risk of insufficient funds: If the financing channels of the rescue fund are limited, or there is abuse in the use process, the fund will not be able to meet the actual demand and limit its rescue ability.
