Introduction: Motorcycling is one of the most important factors of causing injury and motorcyclists are assumed to be as a vulnerable group of road accidents. Evaluation of epidemiological characteristics of traffic accidents in motorcyclists provides valuable information to be used for determination of research priorities. This study aimed to investigate the epidemiology of country-level traffic accidents among motorcyclists in 2013.

Methods: In this Cross-sectional study data was collected and studied from the national accidents record program in 2013. All traffic accidents, that injured people has received medical services in any private or public hospitals, were considered. Incident rate of accidents in motorcyclists was calculated per ten thousand. For the occurrence of accidents, GIS software package was used and data analysis was done by Ecxel 2010 and Stata 11.

Results: In the present study, all injured motorcyclists included 168239 male and 23222 female. Number of traffic accidents in men was higher than women [87.9% and 12.1%, respectively] and the most affected people were in range of 20-24 years old group. Also, most of the traffic accidents has occurred on streets and alleys (84.12%).

Conclusion: Most of the traffic accidents has occurred in young people and urban areas. To reduce the risky behaviors and therefore decrease in the rate of motorcyclists’ traffic accident, development of strict laws and improvement of the cultural awareness should be emphasized more strongly.
