This paper contains the research about suffering motorcyclists in the Republic of Croatia during the period from 2011 to 2015. The aim for this research is focused on representation of complexity of the problem, especially those associated with causing serious traffic accidents. In most countries, the concequences of suffering motorcyclists are certainly injuries in traffic accidents. The same situation is also present in Croatia, where traffic accidents are one of the most important problems just because of the high percentage of mortality. The problem in the question is tirelessly trying to become solved through legislation, information, education, control and introduction of various preventive measures to reduce the number of motorcyclists. The investigation carried in this thesis, presents the causal link of traffic accidents with motorcyclists in Croatia. Furthermore, there are also the factors defined as those that mostly affect the occurrance of the traffic accidents with motorcyclists and as situations which cause death consequences. It is necessary to carry out certain activities, for example various preventive-educational workshops, which should be free and guide by professionals if it's possible, and in order to reduce the number of traffic accidents, dead and injured people and especially the number of suffered motorcyclists. With this model of preventive-educational activities, it will probably be possible to act on conscience of motorcyclists.
