This paper's main objective is to explore the relationships between personality factors, attitudes toward traffic safety and risky driving behaviors among young Taiwanese motorcyclists. A second objective is to examine the gender difference in the effects of personality and safety attitudes on risky driving behaviors. The study sample consisted of 257 student participants from a Taiwanese university. The results show attitudes toward traffic safety are directly associated with risky driving behaviors while having direct effects on attitudes toward traffic safety, personality traits are also found to influence risky driving behaviors indirectly mediated by traffic safety attitudes. Practical implications for traffic safety of young motorcyclists are also discussed.
