Senator Seyarto's transportation safety initiative directs the California Department of Transportation to analyze the state's most dangerous highway locations and develop targeted solutions for these high-risk areas. The measure requires Caltrans to identify the top 15 locations with the highest vehicle collision rates across the state highway system, based on data from multiple calendar years selected by the department.

The legislation establishes a three-part study framework: identifying high-collision locations, determining potential safety improvement projects for each site, and analyzing common factors that delay project implementation. This comprehensive assessment aims to provide insights into both immediate safety needs and systemic barriers to project delivery. Caltrans must complete and publish the study on its website by January 1, 2027, making the findings accessible to the public.

The measure builds upon Caltrans' existing authority over the state highway system by creating a structured approach to safety project planning. While the bill requires no additional appropriations, it involves fiscal committee review to evaluate potential budgetary implications of the study and subsequent project recommendations.
