As quadbikes are becoming more and more common the number of accidents also increases. The first aim of this project was therefore to increase our knowledge of the accidents whilst the second aim was to increase our knowledge of how and where quadbikes are used, the mistakes and violations that are made and what situations and behaviours drivers consider as risky. The project was divided into two sub-studies. In the first sub-study 51 road traffic accident registered in Strada-police were analyzed and in the second 7 injured drivers (involved in any one of the 51 road accidents registered in Strada) and 22 non-injured drivers were interviewed. The results show that quadbikes are popular vehicles with many capabilities; as tools, as recreational vehicles and as vehicles for transport. Inexperienced drivers’ lack of knowledge, alternatively experienced drivers’ stress and/or carelessness combined with the quadbikes special characteristics; underage drivers; quadbike-driving under the influence of alcohol and excessive speed may however lead to accidents. Without a helmet the consequences of an accident might become more severe. Based on the results of this study, the authors recommend a series of measures to reduce the number of serious quadbike accident.
