Introduction: Attitude towards speeding plays a key role in predicting speeding behavior. This study aimed to test whether bi-dimensional attitudes towards speeding can independently predict speed limit compliance behavior and which of the positive and negative dimensions of them have a greater contribution. And so, we intended to test whether the positive and negative dimensions of the attitude towards compliance with the speed limit can account for variance in speed limit compliance behavior over and above bi-dimensional attitudes towards speeding. Materials and Methods: A total of 202 people who drive daily in the city of Mashhad voluntarily completed self-report questionnaires measuring their driving experiences, positive and negative attitudes towards speeding and compliance with the speed limit, and past behavior of compliance with the speed limit. The data were analyzed by using multiple regression analysis and SPSS-25 software. Results: The bi-dimensional attitudes towards speeding independently accounted for a significant proportion of the variance of speed limit compliance behavior (R2 = 0.32, P<0.001), and the negative attitude towards speeding was the stronger predictor (β= 0.35, P<0.001). bi-dimensional attitudes towards compliance with the speed limit also accounted for a significant increment (3.6%, P<0.01) to explained variance in behavior. Conclusion: The results provide more support for the bi-dimensional attitudes towards speeding in predicting speed limit compliance behavior and demonstrate that bi-dimensional attitudes towards compliance with the speed limit improve the prediction of the behavior independently of attitudes towards speeding.
