In car to car crash test, smaller and lighter vehicle is considered to be weaker than bigger and heavier vehicle. Generally, SUVs and Light Truck Vehicles(LTVs) are bigger and heavier than passenger vehicles and their drive height and front end stiffness are higher than passenger vehicles. Because of these characteristics SUVs and LTVs cause more severe injury and fatal injury to passenger vehicle at head-on impact. To evaluate SUV and LTV's aggessivity to passenger vehicle, we carried out SUV to passenger vehicle and LTV to passenger vehicle head-on crash test. And finally the way how to reduce incompatibility between SUV and LTV and passenger vehicles is suggested.

In order to evaluate the damage repairability of a SUV vehicle which experienced a low-speed collision, tests were made according to the RCAR testing procedures. Test results concluded ; (1) The deceleration at C.G(center of gravity) of 6.9~11.39 was similar to that for the vehicle. The airbag system was found to affect neither the passenger's safety nor the savings of the repairing costs. (2) In order to improve the repairability of a damaged SUV vehicle after collision, a higher quality of the bumper, according to the RCAR standards, should be used. Part supply system should be changed to allow exchanges of individual components. (3) The current diversity in determining repairing costs shows three different repairing costs. The diversity should be unified in order to reduce the repairing cost, and to improve repairability.<br/> <br/> <br/>

141.841 car-to-car collision had occurred in 2003, and among the accidents 51,796 were rear-end impact. According to a statistics, more than 60% of rear-end impact victims suffer neck injury. This means at least 31,000 neck injury victims have happened in 2003. Head restraint, which is designed to limit rearward head movement and equipped on seat, can considerably protect neck from rear-end impact. In this paper we evaluated head restraint geometry and drivers' sitting position according to RCAR standard and carried out low speed volunteer crash test. The crash speed is 4km/h and N.I.C value is used to determine injul)' probability. Through these research results we can introduce the method to prevent neck injury at rear-end impact.<br/>
