Evidence in literature suggested that motorists' failure to give way to motorcycles at junctions is the main contributory factor to motorcycle-car accidents that involve gap acceptance (i.e., approach-turn and angle crashes). This paper attempts to examine how motorist's failure to give way affects motorcyclist injury severity in angle crashes at T-junctions, while controlling for other factors (demographic, vehicle, crash, and environmental factors). Binary logistic models of motorcyclist injury severity were estimated using the data extracted from the Stats19 accident injury database (1991-2004). Angle collisions were classified into several sub-crashes based on the manoeuvres motorcycles and cars were making prior to the accidents. The modelling results showed that injuries were greatest when a travelling-straight motorcycle on the main road crashed into a right-turn car from the minor road, particularly at stop-/yield-controlled junctions. Such crash pattern was assumed to be an accident involving right-of-way violation. Using binary logistic models, factors determining the likelihood of motorist's failure to yield to motorcycles were also examined. The implications of the research findings of this present study were provided.
