The 2025 Traffic Safety Public Opinion Study was conducted for the California Office of Traffic Safety (OTS) and the Safe Transportation Research and Education Center of UC Berkeley (SafeTREC). The findings of the 2025 Study are based on a sample size and eligibility criteria similar to previous years of data collection. A total of 2,319 responses were collected in April and May 2025 using an online selfadministered survey. Similar to previous years of the study, the survey panelists were provided through Marketing Services Group, a commercial sample and panel vendor.
The survey findings of the 2025 Traffic Safety Public Opinion Study are outlined in this report together with a comparison to previous years of data collection. Every effort was made to ensure the data representativeness and accuracy of the findings. To ensure a sample composition comparable to previous years, six quota groups were set for age and gender groups based on the California census, as well as based on the age groupings of previous waves of the Traffic Safety Study. To be eligible to participate in the study participants were required to have a valid California driver’s license, live in California, and be 18 years or older. Screened and eligible respondents were forwarded to a brief 10- minute self-administered online survey programmed and managed by Ewald and Wasserman Research (E&W).
