Summary
The 2021 Traffic Safety Culture Index (TSCI), published by the AAA Foundation for Traffic Safety, addresses the rising rate of traffic fatalities in the United States following the initial onset of the COVID-19 pandemic. With traffic volumes increasing and fatalities projected to reach their highest levels since 2005, the study aims to deepen the understanding of America’s traffic safety culture. Specifically, it investigates public perceptions, attitudes, and self-reported engagement in unsafe driving behaviors to inform the development of effective countermeasures. The research focuses on the disconnect between drivers’ awareness of risks and their actual behaviors, examining factors such as perceived danger, likelihood of apprehension, and social disapproval. The study utilized an online survey administered between July 26 and August 30, 2021, to a probability-based sampling panel of 2,657 licensed U.S. drivers aged 16 or older who had driven at least once in the preceding 30 days. Participants were asked to evaluate the danger of various unsafe driving behaviors, their perceived likelihood of being apprehended by police, the level of social disapproval from important individuals, and their support for relevant laws. Additionally, respondents reported their own engagement in these behaviors over the past 30 days. The survey covered distracted driving, aggressive driving, drowsy driving, and impaired driving. Key findings reveal significant discordances between perceived risks and actual behaviors, particularly in distracted driving. While 92% of drivers viewed texting while driving as very or extremely dangerous, 26% admitted to doing so, and 57% used hands-free technology for communication while driving. Drivers generally underestimated the likelihood of apprehension; for instance, only 43% believed they would be caught texting while driving. In contrast, impaired driving showed higher alignment between perception and behavior, with 94% viewing alcohol-impaired driving as dangerous and only 7% reporting such behavior. However, perceptions of marijuana-impaired driving were less severe, with only 65% viewing it as dangerous. Correlation analysis indicated that risk-taking behaviors were associated with perceived danger and social disapproval but showed no or weak association with the perceived likelihood of apprehension. Speeding behaviors exhibited lower discordance, suggesting that perceived danger and social norms are stronger deterrents for speeding than for other risky behaviors. The significance of these findings lies in identifying the specific psychological and social factors that influence driver behavior. The lack of association between perceived apprehension and risk-taking suggests that enforcement visibility alone may not deter unsafe driving. Instead, the strong correlation between social disapproval, perceived danger, and behavior indicates that interventions focusing on social norms and risk perception may be more effective. The data highlight that while drivers recognize the dangers of most unsafe behaviors, the gap between knowledge and action remains wide, particularly for distracted driving, necessitating targeted strategies to bridge this divide.
Key finding
There is a significant discordance between drivers' perceptions of danger and social disapproval and their actual engagement in unsafe driving behaviors, with perceived danger and social disapproval showing stronger alignment with speeding behaviors than with other risky actions.
