Abstract
            Background and aims: Wearing a seat belt significantly reduces the severity and fatality of road  traffic injuries. This study aimed to predict seatbelt-wearing behavior among rural drivers using  the Theory of Planned Behavior (TPB) and to identify its influencing factors.  
  Methods: This study was conducted among 450 rural drivers in the Hashtrood district of Iran using  a random sampling method in 2023. Data were collected through a structured questionnaire  containing questions on demographic characteristics, general traffic-related behaviors, and  seatbelt use behavior based on the TPB constructs. Regression analysis was conducted using  SPSS software (version 16) to predict TPB constructs.  
  Results: The findings indicated that 59.1 % of drivers strictly adhered to the traffic rules.  However, only 21.4% of drivers used the front, and 19% used seatbelts in the rear seat on  rural roads. Based on regression analysis of TPB constructs, subjective norms, attitude, and  perceived behavioral control considerably predicted behavioral intention to use a seat belt  (P<0.05, R2=0.422, adjusted R2=0.417). Furthermore, the constructs of behavioral intention  and perceived behavioral control were found to be significant predictors of actual seatbelt use  behavior (P<0.01, R2=0.283, adjusted R2=0.280). Adherence to traffic rules, parental behavior,  exposure to seatbelt use training by parents and friends, and being fined for not wearing a seat  belt significantly impacted the seatbelt use behavior (P<0.05).  
  Conclusion: The results of this study demonstrated that TPB predicted seatbelt use behavior  among rural drivers. Educational preventive programs grounded in TPB principles could improve  seatbelt use behavior among rural societies.
