Introduction: The recent growth of the commercial motorcycle sector in Kenya has seen a concomitant rise in road traffic accidents (RTAs). However, the correlates of RTAs involving commercial passenger motorcycles are largely unknown in Kenya and other developing countries. We sought to determine the incidence of commercial motorcycle accidents (MCAs) in Embu town, Kenya and its correlates. Methods: In January 2018, we recruited 202 commercial motorcycle riders and collected baseline data by means of a questionnaire in Embu town. We then followed them on weekly basis for 3 months till April 2018 to quantify the number of MCA events. Multivariable cox proportional hazards regression models were built to relate the incidence of MCAs and their correlates. Survival analysis was carried out using the Kaplan-Meier approach. Results: We quantified 48 MCA episodes translating into an incidence of 3 crashes per 1000 person-days. On multivariable analyses, riders in singlehood marital status were almost twice as likely to experience a MCA compared to those married [Adjusted HR (AHR) =1.8 (CI: 1.1, 3.4), p=0.046]. Khat (Catha edulis) users were 2-fold likely to experience a MCA relative to non-Khat (Catha edulis) users [AHR=2.1 (CI: 1.1, 4.2; p=0.021]. Conclusion: Efforts to prevent MCAs need to include a program for screening and educating young riders on the dangers of khat Catha edulis use.
