the Transportation Injury Mapping System at UC Berkeley, combined across all 58 counties. Figures
cover collisions reported to the CHP; minor crashes that were never reported do not appear.
2014 is excluded from this page because at least one county's source
extract holds only a partial year of records for it.
Road and intersection names are as recorded by the reporting officer; see individual county
reports for county-specific figures.
