In order to understand the influences of personality traits behind drivers' unsafe driving behavior，relevant studies on the relationship between personality traits and driving behavior at home and abroad since 2000 were reviewed. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) standard，17 688 articles were retrieved from well-known domestic and foreign databases. After removing 3 160 duplicate articles，14 263 irrelevant articles and 198 non-excellent articles，67 excellent articles were finally included in this study. The relationships between different personality traits and unsafe driving behavior in these articles were summarized and sorted out. The results show that the five personality dimensions of the Big Five personality have different relationships with driving behavior. While sensation-seeking and impulsivity are both strong predictors of unsafe driving behavior，the latter has a stronger predictive ability. The direct predictive ability of driving anger on unsafe driving behavior is not strong. Additionally，factors such as normlessness，trait anxiety，altruism and narcissism have influence on unsafe driving behavior，although there is limited research on these. Furthermore，attachment，trait emotional intelligence，collectivism and abnormal personality traits need more tests. Some research results from Chinese samples diverge from the broader body of research，suggesting a need for cross-cultural studies.
