Source: California Highway Patrol Statewide Integrated Traffic Records System (SWITRS), via 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.
