The study was designed to provide some knowledge of one aspect of driver behavior the effects of traffic controls upon turn-signalling behavior of motor vehicle operators. For this purpose, three types of intersection traffic control were chosen for study. Two-way stop, four-way stop, and signal controlled intersections were selected for comparison of their effects upon the frequency of use and the distance of employment of left turn signals given by motorists performing such turns. Results were obtained from the analysis of data which indicated that several definite relationships exist between left turn-signalling behavior and type of intersection traffic control. Author
