        Motorcycle users’ traffic violation is a crucial barrier to improve road safety in Taiwan. Just like running the red light, right-turn-on-red and speeding behaviors are common on the road and lead to high accident risk. To reduce motorcycle users’ traffic violation, improving engineering, enforcement and education of traffic safety are three efficient ways. The content of driving education usually contains risk perception, driving concept and driving skills. In recent years, traffic safety education’s effect didn’t grow significantly. Most of the drivers might have enough driving skills and knowledge, but traffic violation keeps occurring on th road and shows that drivers aren’t alert enough to violation. The emphasis on traffic violation should be improved.
        Based on Theory of Planned Behavior(TPB), the study designs questionnaire to measure latent construct like obligation to obey the law, attitude to obeying the law, and attitude to traffic enforcement. Applying Rasch Model and Structural Equation Modeling(SEM) to analyze people’s ability and the construct’s cause to people’s intention to violate traffic rules. The study collects 420 samples in Taipei city and 404 samples in Xinbei city.After Path Analysis, the study finds that people’s obligation to obey the law, attitude to obeying the law and attitude to enforcement have a negative relationship between intention to violate traffic rules, especially people’s obligation to obey the law and attitude to obeying the law.The study also analyze the effect of personal status like age and gender.Figuring out the difference of law compliance among groups. And the results show that people’s concept of obedience to law decreases along with the growth of age. The result also points out that the education of obedience to traffic rules should be well-designed and promoted purposefully to the object.
