This paper discusses the design aspects of bus frontal impact behavior as one of the main subjects of bus crashworthiness and surveys conditions and results of previous full impact laboratory tests comparing the FEM simulation results carried out on a Hungarian Ikarus bus.

Clarifying the adequate background gives possibilities for checking bus passive safety solutions by computer and the best utilizable resolutions can be applied in the standardized production. This paper shows frontal impact test arrangements of a 10 tons’ city bus with three different impact speeds and computer simulation versions of these real tests. It gives possibilities to compare the test results to the requirements of current bus regulations.
