"The results indicate that the negligent operators do not constitute a homogeneous group with respect to either the personal variables or the attitudes expressed toward the law, the police, or themselves...[they] therefore, fail to support the common belief that drivers who have unfavorable attitudes toward self or society become serious traffic violators and that such violators have developed unfavorable attitudes toward traffic laws, enforcement agencies, or themselves as a result of frequent apprehension for traffic violations...In conclusion, it appears that the drivers used in this study are not different from other drivers in the characteristics considered, except in the frequency of traffic violations on their records.".
