Crashes between pedestrians and trucks, which were fatal to the pedestrians and occurred during 1986-90, were studied. Police reports were used to develop a crash typology. Comparisons were made with crashes between pedestrians and other vehicles. Pedestrian fatalities in crashes with trucks were more likely to occur at intersections, at traffic signals, during daylight, and to involve older pedestrians. Most fatal injuries were to the head and chest regions. Obstruction of driver visibility, caused by truck design, appears to be a factor in crashes at intersections. Emphasis should be placed on separating pedestrians and trucks and on designing trucks to improve visibility.
