Sources & Methodology

Where our information comes from

Current accident information originates from public agency sources, such as California Highway Patrol public traffic incident information. Developing information may change as incidents develop and are confirmed by responding agencies.

Authoritative references

We reference the following public agencies and research sources where appropriate:

• California Highway Patrol (CHP)
• California Department of Motor Vehicles (DMV)
• California Department of Insurance
• California Office of Traffic Safety (OTS)
• Caltrans
• UC Berkeley SafeTREC / TIMS
• National Highway Traffic Safety Administration (NHTSA)
• Local police, sheriff, and fire agencies

We cite these sources for reference only. California Car Accidents is not affiliated with any of these agencies, and references do not imply government endorsement.

Verification

Each incident carries a verification status. Sensitive claims — involving fatalities, serious injuries, identities, fault, DUI, arrests, or criminal conduct — require stronger verification before publication. Initial information may change.
