Subjects' speed estimations, traffic pattern judgments and passing judgments from 16mm motion pictures taken from an automobile moving along a freeway and a rural road indicated a high positive correlation between tests and retests of speed estimations on a freeway; little correlation between speed estimations on freeways versus rural roads; consistant overestimations of speed from films taken on freeways (compared to real speeds); consistant underestimations of speed from films taken on rural roads (compared to real speeds); no correlation between speed estimations per se and judgments of traffic patterns or passing; a tendency for the drivers to not pass where legality or distance is questionable; and a positive influence of a posted No Passing Zone sign.
