This paper starts with an analysis of the SSF coefficients corresponding to different vehicle models in China，discusses the trend of vehicle rolling accidents caused by structural changes in vehicle registration in recent years，and analyzes the variation curve of the average number of deaths caused by single rolling accidents. It shows that the rolling accident is a form of road traffic accident with a low incidence rate but a high mortality rate. Based on the data of automobile rolling accidents，the paper analyzes the environmental characteristics，rolling form characteristics，vehicle characteristics and occupant damage characteristics of automobile rolling accidents. At the same time，it puts forward that the auto rolling safety standard and regulation tests can choose the curbstone test，the spiral rolling test and the slope rolling test. They respectively correspond to tumbling，throwing and falling.
