Backgrand and aim: Mistakes and violations leading to driving accidents and their consequences, especially in most developing countries, are considered as one of the main causes of death and injury. The aim of this study was to determine the relationship between noise exposure, noise annoyance, aggression and driving behavior of drivers. Material and Methods: In first, two linear taxi routes were selected to compare the noise exposure of drivers. A total of 133 drivers were participated in the study by convenience sampling method. According to ISO 9612: 2009, a 4-hour short-term dosimeter was performed during the daily routine of drivers, and finally, an 8-hour equivalent was calculated. Demographic questionnaire, socioeconomic status including 5 questions, one-question noise annoyance questionnaire with 0-10 scale, aggression questionnaire, 29 questions with 4 sub-scales of physical aggression, verbal aggression, anger and hostility, and driving behavior questionnaire including 50 questions and 4 Sub-scale of errors, mistakes, intentional violations, and unintentional violations among distribution drivers were completed and collected. Data were analyzed by SPSS software version 25 using independent t-test and one way ANOVA, Pearson correlation and multivariate regression tests. Results: The average noise exposure of drivers in the high noise was 78.7 dB and in the low noise route was 79.75 dB. There was a significant and direct correlation between noise exposure of drivers and all behavioral parameters. In general, noise exposure had a significant direct correlation with behavioral parameters. As well as demographic factors such as vehicle model and socioeconomic status were associated inversely with driving violations. Conclusion: According to the results of this study, some practical suggestions are made to improve the working conditions of taxi drivers. Installing acoustic absorbers in taxi routes, installing an acoustic absorbent to prevent the sound transmission of motor vehicles into the cabin, acting to develop regulations and standards for identifying, measuring, and controlling harmful factors in the taxiers' work environment, investigating the personality aggression status of applicants for a certificate card Driving before giving a license, conducting periodic psychological assessments of drivers at regular intervals and extending the license, holding classes on how to control aggression by relevant institutions, and requiring applicants to obtain a certificate for participation in these courses and grants To the driver To replace old vehicles with new vehicles.
