A behavioural study of quadbike drivers


As quadbikes are becoming more and more common in Sweden the number of accidents also increases. The first aim of this study was therefore to increase our knowledge of how and where quadbikes are used, the mistakes and violations drivers make and what situations they consider as hazardous. The second aim was to increase our knowledge of the accidents. Seven injured and 22 non-injured quadbike drivers were interviewed. The results show that quadbikes are highly appreciated as tools, as vehicles for recreation and as means of transport. Inexperienced drivers’ lack of knowledge, alternatively experienced drivers’ stress and/or carelessness combined with the quadbikes special characteristics; underage drivers and passengers; quadbike-driving under the influence of alcohol and excessive speed are all factors that could contribute to accident involvement; and without a helmet the consequences of these accident might become more severe. To combat these problems, and to reduce the number of quadbike accidents, the authors suggest changes to the law for helmets, a short specialized course focusing on practical quadbike driving in combination with a theoretical education focusing on risk awareness as well as a national mobilization against quadbike driving under the influence of alcohol and underage drivers.
