This paper presents preliminary findings from two studies that investigate how motorcyclists' behaviour differs from that of car drivers. In the first study three groups were involved in simulated driving conditions: motorcyclists responding as if on their motorcycle; motorcyclists responding as if in their car; and non-motorcyclists responding as if in their own car. Tests concerned hazard perception, close following, gap acceptance, overtaking and speed. Subjects also completed questionnaires and computer exercises. Results were analysed and four factors determined. Motorcyclists responding as if on their own motorcycles were more risky under the speed/attitudes factor. Motorcyclists are not necessarily less safe as road users, although they behaved more dangerously. The second study involved roadside observation of motorcyclists and car drivers: the data collected mirrored that from the first study. For the covering abstract see ITRD E116025.
