Forensic medical diagnostics of the injuries inflicted to the drivers and the passengers of bicycles (scooters, mopeds, quadrocycles, etc.) remains a serious challenge for the specialists involved in forensic medical and combined medico-autotechnical expertises. The present article is an overview of materials pertinent to the analysis of this form of traffic injuries. The approach to the analysis is exemplified by the case of repeated panel expertise with the purpose of elucidation of the mechanisms and the sequence of events leading to a combined blunt injury in the driver and the passenger of a scooter resulting from the collision with a car moving at a high speed in the same direction. Both victims presented with a whiplash injury to the brain stem region responsible for their immediate death at the scene of the accident. The results of the expertise allowed to differentiate between the driver and the passenger in terms of the extent of the injury. The authors emphasize the necessity of and good prospects for further traffic injury research bearing in mind a great variety of the aforementioned means of transportation.
