    In our country, there are some problems in the coach sector related to the manufacture of buses, among which are high weight and low resistance to rollover, which has resulted in high mortality rates in traffic accidents. Taking as reference previous studies, based on research carried out worldwide, national and international regulations, the current structure of the bus for interprovincial service IM9 on Mercedes Benz O500 RS 1836 chassis of Miral Autobuses, was based on the theory and the finite element method with the analysis software Ansys, which was validated by a physical rollover test of the most critical section of the structure in accordance with the provisions of Regulation 66 of the United Nations, the structure was modified with the material that the company currently uses, identifying oversized segments, by varying the thickness, its weight was reduced without forgetting rollover resistance, reliable results were achieved to ensure the quality and safety of the products manufactured by Miral Autobuses. It was determined by an adequate design, at specific points of the bus structure reducing its weight always keeping in mind the most important aspect, the conservation of lives, which translates into the fact that the passenger survival zone is never invaded during a rollover accident. After having done the research, it is recommended to work on composite materials for the body components, which can reduce weight in order to be more competitive in comparison to other bus body builders that are selling its products in our country, in the future, we will sell our buses in international markets.
