Human factors constitute a class of prominent road safety related factors. In the present study, human factors of driving were studied by investigating sex differences and gender roles in relation to impulsive driving and driving anger expression. A total of 425 drivers between the ages of 18 and 56 (M = 25.46, SD = 7.58) participated to the study and completed a series of questionnaires including a demographic information form, the Bem Sex Roles Inventory, the Impulsive Driver Behaviour Scale and the Driving Anger Expression Inventory. According to the ANCOVA results, male drivers showed higher functional impulsivity, lack of premeditation and use of the vehicle to express anger than female drivers. Additionally, hierarchical regression analyses showed that masculinity was positively associated with functional impulsivity, urgency and the dimensions of aggressive anger expression. However, femininity was positively associated with functional impulsivity and adaptive/constructive anger expression, but negatively associated with the dimensions of dysfunctional impulsivity and aggressive anger expression. Overall, the results showed the significant solo effects of masculinity and femininity on impulsive driver behaviours and driving anger expression, over and above the effects of sex, and the interaction between sex and gender roles. In the present study, previously reported findings indicating the relationships between sex and gender roles and driving anger expression were supported and extended by providing the literature with the contribution of answering the question how sex and gender roles are related to impulsive driver behaviours. The findings of the two related concepts of impulsive driving and driving anger expression were discussed in light of the current literature. Contributions, implications and future research directions concerning road safety practices were presented.

人为因素构成了一类突出的道路安全相关因素。在本研究中，通过调查与冲动驾驶和驾驶愤怒表达相关的性别差异和性别角色来研究驾驶的人为因素。共有 425 名 18 至 56 岁的司机（M =  25.46，SD = 7.58) 参与了研究并完成了一系列问卷，包括人口统计信息表、Bem 性别角色量表、冲动性驾驶员行为量表和驾驶愤怒表达量表。根据ANCOVA的结果，男性司机比女性司机表现出更高的功能性冲动、缺乏预谋和使用车辆表达愤怒。此外，层次回归分析表明，男性气质与功能性冲动、紧迫性和侵略性愤怒表达的维度呈正相关。然而，女性气质与功能性冲动和适应性/建设性愤怒表达呈正相关，但与功能失调性冲动和攻击性愤怒表达的维度呈负相关。全面的，结果表明，男性气质和女性气质对冲动驾驶行为和驾驶愤怒表达的显着单独影响超过了性别的影响，以及性别和性别角色之间的相互作用。在本研究中，先前报告的表明性别和性别角色与驱动愤怒表达之间关系的发现得到了支持和扩展，为文献提供了回答性别和性别角色如何与冲动驾驶行为相关的问题的贡献。根据当前文献讨论了冲动驾驶和驾驶愤怒表达这两个相关概念的发现。介绍了有关道路安全实践的贡献、影响和未来的研究方向。
