Authors Abstract
Content
A study of vehicle accident data from insurance claim files was conducted to determine the relative effectiveness of red and amber turn-signal systems in reducing rear-end collisions. The effectiveness was measured in terms of the relative frequency of accidents involving these systems, with respect to a number of vehicle, environmental, and driver factors. Control for vehicle exposure was made by comparing the non-turning accidents with the turning accidents for the relevant rear-turn-signal systems.
Analyses revealed that there were no statistically significant differences in rear-end accident rates between the red and amber turn-signal systems. On the basis of safety benefits, the results of the study did not appear to provide sufficient justification for changes to the present Motor Vehicle Safety Standards regarding the functional separation and colour coding of a rear-turn-signal system.
