To evaluate the rear seat occupant safety, two frontal barrier tests were conducted according to the test procedures of the New Car Assessment Program (NCAP). The NCAP test method is identical but more severe condition than the vehicle safety regulation of the Ministry of Construction and Transportation (MOCT). In each test, the injury data of head, chest and femur for driver, front and rear passenger dummies were measured and analyzed. The head and chest injury of rear seat passenger dummies are lower than those of the driver and front passenger dummies. The femur load of the rear seat dummies is higher than those of the front seat dummies. The results show that the rear seat passengers are safer than the driver and front passenger. The submarining phenomenon is occurred in the rear seat<br/>
passenger dummies. The lower legs of the rear seat dummies pushed the front seat back. The submarining effect of the rear seat passenger dummies may result in the behavior of the driver and front seat dummies. Also, this effect may result in the increase of the injuries of the driver and front passenger.<br/>
