Summary
This report analyzes temporal trends in U.S. traffic safety culture from 2009 to 2012, addressing the need to measure social norms, attitudes, and self-reported behaviors that traditional crash data cannot capture. The AAA Foundation for Traffic Safety defines traffic safety culture as a social climate where safety is highly valued and rigorously pursued. The study aims to document indicators of this culture and identify changes over time to inform future prevention efforts. The analysis utilizes data from the Traffic Safety Culture Index (TSCI), an annual survey of U.S. residents aged 16 and older. In 2009 and 2010, data were collected via random-digit dial telephone sampling; in 2011 and 2012, the mode shifted to an Internet-based panel, with accommodations provided for respondents lacking Internet access. The survey instrument assessed perceptions of threat, social norms regarding acceptability, self-reported driving behaviors, and support for legislative countermeasures. Data were weighted to reflect the U.S. population demographics, with average 95% confidence intervals of ±2.5–3.0 percentage points. Key findings reveal a significant divergence between perceived threats and actual behaviors. Perceptions of the threat posed by risky driving decreased substantially across multiple categories. The perceived threat of driving after drinking dropped from 90% in 2009 to 69% in 2012, and the perceived threat of drowsy driving fell from 71% to 46% over the same period. Similarly, concern about texting while driving declined. Despite these decreasing risk perceptions, self-reported engagement in dangerous behaviors remained high or increased. For instance, the proportion of drivers reporting they ran a red light in the past 30 days rose from 29% in 2009 to 38% in 2012. Approximately one-third of drivers reported reading texts or emails, and over two-thirds reported talking on cell phones while driving. Social norms remained largely stable, with high levels of condemnation for texting and drunk driving, though acceptance of hands-free phone use and speeding on freeways remained relatively low. Support for laws banning texting and hand-held phone use remained strong (80–87% and 67–71%, respectively). The study concludes that while public condemnation of risky behaviors persists, the perceived danger associated with them is declining, particularly for alcohol-impaired and drowsy driving. This trend is concerning given the established link between risk perception and behavior. The authors suggest that current awareness campaigns may be insufficient to alter perceptions or behaviors. They recommend targeting resources to increase perceived susceptibility to harm and considering stricter legislation and enforcement to associate negative consequences with risk behaviors, as psychological defenses against health warnings may be difficult to overcome.
Key finding
From 2009 to 2012, U.S. drivers' perceived threat from alcohol-impaired and drowsy driving fell substantially, yet self-reported engagement in risky behaviors—including distracted driving, red-light running, and occasional impaired driving—remained common and largely unchanged.
