Abstract
The n.39 case studies analysed in this report are a representative sample of motorcycle fatalities in Northern Ireland between 2004 and 2010. The report contains an analysis of the collisions investigated and includes information relating to vehicle data, the collision scene and the environment as well as human factors. Overall, n.41 motorcyclists were fatality injured. The evidence provided in this report indicates that each road traffic collision is unique but that in all cases the time frame from the perceived hazard to the conclusion of the impact either with another vehicle or with road infrastructure was typically between 2 and 3 seconds.
