The purpose of this paper is to provide additional and specific information on the underreporting of pedestrian-motor vehicle collisions. Knowledge of the sequence of events during the impact of the distracted pedestrian and the vehicle has been crucial for proper reconstruction of the incident, along with vehicle speed at the moment of the impact, how far the person was thrown after impact, and when the driver braked. The responsibilities of emergency medicine physicians consists of: (1) preventing severe morbidity due to injury patterns manifested in pedestrian trauma; (2) describing the incident scene and reconstructing pedestrian-vehicle collisions; and (3) identifying the mechanism(s) of injury, the initial and final positions of the pedestrian, and the sequence of events leading to trauma.
