Summary

This study investigates the concept of "traffic safety citizenship," defined as discretionary, prosocial behaviors where individuals intervene to improve the safety of others, such as asking drivers to wear seat belts or stop texting while driving. The research was motivated by the need to shift traffic safety strategies from targeting only risky individuals to empowering the majority of safe road users to influence unsafe behaviors. The authors aimed to measure the prevalence of these interventions and identify the underlying values, beliefs, and attitudes that drive engagement in such behaviors. The researchers developed a survey based on an augmented integrated behavioral model combining Value-Belief-Norm Theory, the Reasoned Action Approach, and the Prototype Willingness Model. The survey measured attitudes, behavioral beliefs, perceived norms (descriptive and injunctive), prototypical images, and perceived control regarding interventions with family, friends, acquaintances, and strangers. Data were collected from U.S. adults aged 18 and older via mailed and internet-based methods. The instrument assessed both past behavior (interventions in the last 12 months) and willingness to intervene in hypothetical scenarios, alongside support for policy strategies like seat belt enforcement and distracted driving restrictions. Results indicated that approximately half of respondents had encountered situations involving unbuckled passengers or distracted drivers in the past year. Among those who had the opportunity to intervene, more than half did so, with intervention rates significantly higher for socially close individuals (family and friends) compared to strangers. Most respondents held favorable attitudes toward intervening, viewing it as sensible and responsible. Statistical analysis revealed that the perception of descriptive norms—believing that most people do intervene—was strongly correlated with actual intervening behavior. Additionally, respondents generally supported policy strategies aimed at increasing seat belt use and reducing distracted driving. The findings suggest that traffic safety culture is significantly influenced by perceived social norms and the strength of social relationships. The strong correlation between perceived descriptive norms and behavior implies that interventions promoting the visibility of safety citizenship behaviors could increase engagement. By fostering a culture where intervening is viewed as normal and expected, communities can leverage the majority of safe drivers to reduce risky behaviors. The study concludes that growing traffic safety citizenship requires strategies that enhance these shared beliefs and norms, offering a pathway to achieve broader improvements in traffic safety beyond traditional enforcement methods.

Key finding

Respondents were significantly more likely to intervene on seat belt and texting violations with family and friends than with acquaintances or strangers, and their own intervening behavior was strongly correlated with the perception that most other people also intervene.
