Background and Aim: Motorcyclists constitute a large and growing portion of the victims of traffic accidents in Iran. Reasons include high motorcycle production rates and relatively low prices. This case control study was conducted to look at the role of a number of presumed risk factors in Kashan, a city with high motorcyclist casualty rates.

Material and Methods: Cases for this study were motorcyclists listed by the Traffic Police as either injured or killed over the period extending from 20/3/2005 to 20/9/2005. For each case, another motorcyclist who regularly passed the point of accident on the same day of the week was taken as control. Supplementary data were gathered by interview with the subjects (when possible) or a first-degree relative (for dead cases). Data were analyzed using the SPSS software.

Results: There were statistically significant relationships between the occurrence of death or injury and the following set of factors: age, marital status, job, education, vehicle ownership, BMI, driving experience with motorcycles and cars, time spent driving in one day, driver's estimate of his own speed, and  weather conditions.

Conclusion: This study highlights the importance of effective interventions and offers some useful information for policy makers.
