Factors Influencing Risky Driving Behavior Among Military Drivers: The Moderating Effect of Perceived ADAS Benefits

This study investigates the determinants of risky driving behavior among military drivers and examines the moderating role of perceived benefits of Advanced Driver Assistance Systems (ADAS) within an extended Theory of Planned Behavior (TPB) framework. Military driving is characterized by mission-oriented tasks, hierarchical decision-making, and frequent exposure to high-risk conditions; therefore, TPB-based findings from civilian contexts offer limited explanatory power for military drivers’ behavior. To address this limitation, the study incorporates risk sensitivity and aggressiveness as direct predictors, acknowledging that stable personality traits may exert immediate behavioral effects in demanding military environments. Survey data were collected from soldiers and officers with military driving experience, and structural equation modeling was conducted using SPSS 25.0 and AMOS 22.0. The results indicate that attitude, perceived behavioral control, and moral norm negatively influence risky driving intention, while intention positively predicts risky driving behavior. Risk sensitivity and aggressiveness also directly affect risky driving behavior. Furthermore, perceived benefits of ADAS strengthen the negative effects of TPB-related factors on risky driving intention, suggesting that favorable technology perceptions reinforce resistance to risky driving. Overall, this study integrates cognitive, dispositional, and technological factors into a unified framework and provides practical implications for military traffic safety policies beyond conventional training-based approaches.
