The purpose of this study is to examine the factors the affect the perceived fairness of the traffic violators on their citations. The results show that police' correct use of the law articles in determining violation punishment, the consistency in enforcement, the positive interpersonal interaction between police officers and violators, and the cultural factors all increased violators’ perceived fairness of their violation citations. In addition, the correct use of law articles, police’ biases, unconcern about the situational factors that cause violations, fix-up in law enforcement, and the age of violator were related with the perceived unfairness in the violators.
