The purpose fulness as well as necessity of cars safety determination has been exhibited. Moreover, the principles of the flnite element method (FEM) have been explained as well as its usefulness as a crash testing simulation tool. The programs which have been established in order to explore possibilities of virtual testing have been described. The paper contains the designs of the large vehicles passive safety devices. The problems concerning simulations of large vehicles — cars accidents have been emphasized. Moreover, the conversion of the experimental testing in to the virtual testing has been pointed out along with its advantages and disadvantages. Furthermore, the paper describes the proposition of the safety improvement in case large vehicle -  car accidents investigated with aid of virtual crash testing. The last mentioned system is especially important in terms of truck tractor with a trailer where slipping is very dangerous due to the fact that it can cause breaking the connection and in conseguence roll over. Another, new solution which improves passive safety could be the "active bumper ". The passive safety devices are necessary to reduce danger as well as provide passengers with maximum possible comfort what but a way also improves safety.
