And some opportunities of improving road safety regarding heavy vehicle braking systems were identified. The analysis showed several regulatory weaknesses, among which were found： lack of regulatory controls of vehicles importation, the friction coefficient associated to maximum braking distance is not specified, the use of technologies that guarantee a stable braking is not compulsory, the measuring procedure of braking efficacy in vehicle inspection shows some deficiencies, and little controls have been established on maintenance practices of heavy vehicle fleets.展开更多
文摘Accidents involving heavy vehicles might show high mortality rates, so it is important to study ways of reducing them. in this research, it was carried out an analysis of the regulations concerning heavy vehicle braking systems in Costa Rica.
