Abstract
Nine hundred sixty drivers in two Israeli cities were observed as to whether they entered the intersection before the traffic light turned green, in the following four conditions: (a) no other cars were waiting at the intersection, (b) at least two cars were waiting behind the target driver, (c) one or two cars were waiting to the side(s) of the target driver, and (d) at least two cars were waiting behind each car in the first row. The smallest proportion of traffic violations occurred among the solitary drivers, and the largest proportion occurred among the drivers who had other drivers at the side(s) and to the back. The women tended to be less affected by the presence of other drivers than the men did. (Author/publisher)
