Violation of traffic rules is an important factor behind traffic accidents. Attempts to explain why drivers are violating have shown that attitudes, norms and driver interactions are important factors. A questionnaire, based on the theory of planned behaviour (TPB), has been used to explore effects of attitudes, norms, perceived behaviour control, etc. on various self reported violations in traffic. The questionnaire was administered to a sample of license holders and more than 1800 answers were obtained (return rate 68%). Factor analyses of thirteen different self reported violations resulted in three distinct dimensions of violation - speeding, close following and violations against unprotected road users. In the this paper a comparison between TPB-models explaining speed violations and violations against unprotected or vulnerable road users, respectively, will be presented.
