Driving is a risky traffic behavior. The psychological, physiological and behavioral characteristics of drivers have a great impact on driving safety, which often determines whether potential accidents may occur. The research shows that female drivers have low discrimination ability to complex traffic environment, and respond less actively than men in stress environment, so they can't cope with emergencies. In addition, There are also significant differences in physical conditions between male and female drivers. The average gap between men and women is quite obvious in terms of vision, physical strength and spatial ability. 
On average, the incidence of fully responsible traffic accidents for male drivers is much higher than that of female drivers for the same mileage
 it is suggested that compared with male drivers, female drivers do have the side of road killer, that is, they are more likely to cause serious traffic accidents.
