Introduction: Motorcycle passengers comprise a considerable proportion of traffic crash victims. During a 5 year period (2006-2010) in Iran, an average of 3.4 pillion passengers are killed daily due to motorcycle crashes. This study investigated the main factors influencing crash severity of this group of road users.
Method: The Classification and Regression Trees (CART) method was employed to analyze the injury severity of pillion passengers in Iran over a 4 y ear period (2009-2012).
Results: The predictive accuracy of the model built with a total of 16 variables was 74%, which showed a considerable improvement compared to previous studies. The results indicate that area type, land use, and injured part of the body (head, neck, etc.) are the most influential factors affecting the fatality of motorcycle passengers. Results also show that helmet usage could reduce the fatality risk among motorcycle passengers by 28%.
Practical Applications: The findings of this study might help develop more targeted countermeasures to reduce the death rate of motorcycle pillion passengers.

Objective: Road traffic injury (RTI) is the second leading cause of death and disability, and motorcycle crashes rank as the first cause of traffic fatality in Iran. We aimed to compare various characteristics between traumatized motorcycle riders and pillion passengers registered with the National Trauma Registry of Iran (NTRI).
Methods: This is a retrospective study of the NTRI, an ongoing multicenter trauma database built on a registry.

Article Synopsis
- Motorcycle accidents involving wheel spokes have become a significant cause of ankle and foot injuries in children under 16 years old in developing countries, particularly during afternoon rides as pillion passengers.
- The study analyzed 30 cases over 11 years, revealing a notable increase in injuries after 2015, with a majority suffering severe injuries such as tendon ruptures and bone fractures.
- Key findings indicate that larger wound sizes and loss of soft tissue are linked to the severity of injuries, highlighting the need for better prevention strategies for child passengers.

This study simultaneously modelled the injury severity of motorcycle riders and their pillion passengers and determine the associated risk factors. The analysis is based on motorcycle crashes data in Ashanti region of Ghana spanning from 2017 to 2019. The study implemented bivariate ordered probit model to identify the possible risk factors under the premise that the injury severity of pillion passenger is endogenously related to that of the rider in the event of crash.

The extremities are the important anatomical regions that are disproportionately injured during road traffic accidents in poor and medium-income countries. The data regarding extremity injuries, particularly in pillion passengers, are minimal globally. We analyzed the pattern of extremity injuries and their association with various parameters such as collision type, seating position, road type, and type of vehicle.

Article Synopsis
- This study investigates the severity of motorized two-wheeler crashes by analyzing police-reported data from 2016 to 2020 in Dehradun, focusing on driver liability.
- It uses an ordinal logistic approach to distinguish between first-party crashes (where the rider is at fault) and second-party crashes (where the rider is a victim), identifying key factors influencing crash severity.
- The findings indicate that factors such as age, type of collision, and road conditions affect crash seriousness differently depending on the crash type, and the research contributes to understanding fatal accidents and developing safety strategies for motorized two-wheeler users.
