This study investigated how elementary schoolers\' personal characteristics such as sensation-seeking disposition, extraversion-introversion, Attention Deficit Hyperactivity Disorder, and impulsivity were associated with their traffic behaviors. 572 first to sixth graders were participated in the study. For the lower grades\' students(first to third), their parents completed the traffic behaviors inventory and for the higher ones(fourth to sixth), they did it by
themselves. To analyze data, correlational analysis, t-test, and LISREL were performed. The results from this study were as followed:
First, students who had higher sensation-seeking disposition, extraversion-introversion, Attention Deficit Hyperactivity Disorder, and impulsivity seemed to violate frequently traffic regulation, whereas students who had lower sensation-seeking disposition, extraversion-introversion, Attention Deficit Hyperactivity Disorder, and impulsivity seemed to violate
infrequently traffic regulations. Second, out of predictive variables, sensation-seeking disposition and impulsivity directly and indirectly had the biggest influence on elementary schoolers\' traffic behaviors, considering the pass coefficients in the model. Especially, because differences in the level of sensation-seeking disposition and impulsivity made a big difference in traffic regulation violation actions, we need to pay attention to children who had
higher sensation-seeking disposition and impulsivity.
