According to a statistics, in recent three years number of traffic accident and casualty remain stand still while casualty by car to car side crash has been increased. This phenomenon is attributed to the two main factors. One is vehicle structure and the other is vehicle safety regulation which does not appropriately reflect current market situation. The distance from vehicle side door to occupant is kind of short compare to vehicle front to occupant, so the likelihood of occupant injury or death at side crash accident is higher than any other types of accident. Even Korean government runs to evaluate and improve vehicle side impact crashworthiness, this program does not reflect current vehicle fleet cause it is based on vehicle fleet of more than 20 years ago. In this paper, three sets of car to car side impact test have done to evaluate occupant injury probability and aggressivity of SUV to passenger vehicle, and based on this result the way to reduce injury and fatality likelihood at side crash is recommended.
