Costa Mesa intersections ranked by reported crashes
21 confirmed surface-street junctions in Costa Mesa, Orange County, carrying 303 reported crashes between them in 2023 and 2024. 29 junctions were attempted here and 21 could be confirmed by two independent sources; the rest were dropped rather than guessed at.
This is a count of reported crashes, not a measure of risk. It is not adjusted for traffic volume, and a difference of two or three crashes between neighbouring rows is within ordinary year-to-year variation rather than a real gap. It says nothing about fault or about any individual claim.
