Summary
The 2019 Traffic Safety Culture Index (TSCI), published by the AAA Foundation for Traffic Safety, addresses the ongoing need to assess American drivers’ values, perceptions, and behaviors regarding traffic safety. As the twelfth annual iteration of this nationally representative survey, the study aims to identify critical indicators of traffic safety culture, including perceived danger, risk of apprehension, social approval of risky driving, support for relevant laws, and self-reported engagement in dangerous behaviors. The research is motivated by the Foundation’s decade-long commitment to understanding these factors to prevent traffic deaths and injuries. The study utilized a probability-based sampling panel of 2,714 U.S. licensed drivers aged 16 and over, weighted to reflect the U.S. population. Data were collected via an online survey between September 6 and October 8, 2019. Participants were required to have driven at least once in the 30 days preceding the survey. The questionnaire measured attitudes toward distracted, aggressive, drowsy, and impaired driving, alongside self-reported frequency of these behaviors. Key findings reveal significant discrepancies between perceived danger and actual behavior. Regarding distracted driving, while 96.2% of drivers view typing on a hand-held cellphone as very or extremely dangerous, 29.3% admitted to doing so in the past 30 days. Similarly, 43.2% reported talking on a hand-held phone while driving. For aggressive driving, 64% perceive speeding on residential streets as dangerous, yet 48.2% reported speeding 15 mph over the limit on freeways in the past month. Drowsy driving was identified as very or extremely dangerous by 96% of respondents, with 97% socially disapproving of it; however, 24% admitted to driving while too tired to keep their eyes open. In impaired driving, 94% viewed driving after drinking as dangerous, yet nearly 10% admitted to doing so recently. Additionally, drivers involved in crashes within the past two years were significantly more likely to engage in self-reported distracted and aggressive driving behaviors. The significance of these findings lies in the persistent gap between high levels of perceived danger and social disapproval, and the continued prevalence of risky driving behaviors. Despite strong public support for laws curbing distracted and aggressive driving, a substantial portion of the driving population continues to engage in these activities. The data suggest that perceived risk of being caught is low for many behaviors, such as drowsy driving (29% believe drivers risk being caught), which may contribute to the persistence of these practices. These insights provide critical evidence for developing targeted educational materials and policy interventions to align driver behavior with safety norms.
Key finding
Although U.S. drivers in 2019 overwhelmingly perceived handheld texting, speeding, drowsy driving, and alcohol-impaired driving as very or extremely dangerous and largely supported related traffic laws, substantial fractions still reported engaging in these behaviors in the past 30 days—including 43.2% talking on a handheld phone, 48.2% speeding 15+ mph on a freeway, 24% drowsy driving, and nearly 10% driving after drinking.
