Aggregate traffic crash data for California from the California Crash Records System (CCRS), maintained by the California Highway Patrol. Covers crashes recorded since 2024, updated daily.
Severity is classified by CHP investigators based on the most serious injury in the crash. High-severity crashes involve at least one fatality or suspected serious injury.
California consistently ranks among the highest-crash states in the US, driven by its 40 million residents, the largest vehicle fleet of any state, and a freeway network exceeding 15,000 miles. The five Southern California counties — Los Angeles, San Diego, Orange, Riverside, and San Bernardino — account for more than half of all statewide crashes due to population density and freeway volume.
High-severity crashes are concentrated on rural two-lane highways and high-speed urban freeways. Pedestrian fatalities have increased sharply since 2020, now accounting for roughly 25% of all traffic deaths in the state — well above the national average of 17%. Speed-related crashes remain the leading primary collision factor in fatal crashes statewide.
The data on this page comes from the California Crash Records System (CCRS), maintained by the California Highway Patrol. CCRS records are investigator-completed — they reflect crashes that received a CHP report or were submitted by a local law enforcement agency. Minor property-damage crashes that were not reported to law enforcement are not included.
