Although a significant proportion of road hazards and their associated health risks in Nigeria involve motorcycles, relatively little research explores whether commercial motorcyclists have unique seasonal accident experiences. This article analyses survey data from 241 commercial motorcyclists in selected terminals in Ifo, Nigeria, to explore how road hazards and health risks experienced differ from one season to another. The study established that seasonality of motorcycle hazards and health risks cannot be assumed across the terminals and routes as some were dominant in either rainy or dry seasons or both. In particular, most motorcycle hazards and health risks were less likely caused by seasonal variation but by human errors and road conditions. The results underscore the importance of collecting commercial motorcyclists' perceptual data because many experience hazards and health risks that are burdensome to them.
