Bus accidents involving rollover are of such violence as is not usually seen in other kinds of accidents. In order to provide busses with a minimal rollover-resistant structure, the Regulation number 66 of Geneve was isssued. Calculations made by means of the Finite Element Method, as well as a subroutine application that has been created for this purpose, are presented. These calculations have been made for an intercity bus structure that is actually working in real life. This technique has been checked by means of the realisation of the test explained in the mentioned Geneve regulation, with a module of the superstructure of the bus, and the subsequent numerical simulation. A high degree of theoretical and experimental correlation is obtained, which confirms it validity. Once the method was assesed, a complete vehicle roll over test simulation was carried out, with and without the application of an energy absorber on each of its upper lateral edges, which is able to absorb 30 % ot the energy released in the impact. The results obtained in the complete roll over simulation prove the efficacy of the use of the energy absorber, and it is inferred that the structure of the bus is able to pass the required regulations.
