This directory compares clearly labeled, illustrative city-level crash estimates and roadway context; it is not an official collision database or a substitute for an incident report. Use it to identify broad patterns, then verify a specific crash through the responsible agency and the linked official traffic-safety sources.
Start with 116 validated OTS county-year records or search 74 reviewed local government sources. The separate city comparison remains available below and is explicitly labeled as illustrative.
Use the hub by question
Use the county explorer for official OTS victim counts, the local source finder for agency records, and the city directory for clearly labeled directional context. If a live claim depends on treatment, evidence, or a deadline, move to case review instead of treating aggregate data as an answer.
Strongest evidence path
Compare the official county rows, open the exact source, then use the local record finder when the question depends on a city or agency.
When to stop browsing
Accident data adds context. It does not answer liability, deadline, or insurer-strategy questions for a live case.
Verified county records
Compare official OTS victim counts by county.
Review 2021 and 2023 source rows for every California county and four road-user measures.

Why people trust this step
The data helps with local context, but a live case usually needs action before more browsing.
If medical treatment, an insurer statement, or a filing deadline is already driving the next move, call or start intake instead of comparing more cities.
Verified records appear first. The separate city estimates remain below for directional context and are never presented as official incident data.
Verified California evidence
California OTS county tables report 231,107 people killed or injured across all 58 counties in 2023, compared with 229,586 in 2021. Those values are sums of the published county rows, not estimates. Use the second explorer view to locate a reviewed municipal or state record for a local question.
Evidence boundary
Official counts describe reported victims or source availability. They do not prove fault, establish what happened in one incident, measure claim value, or rank a person’s risk. The city estimate cards farther down are a different, illustrative dataset.

Evidence center reviewed August 24, 2026
2021/2023
A reproducible two-point comparison of California OTS county-level fatal-and-injury victim counts for all road users, motorcyclists, pedestrians, and bicyclists.
Important limit
This is a two-point 2021-to-2023 comparison, not a continuous annual trend series. No missing year is interpolated.
2021/2023
An All Seniors-sponsored, source-transparent comparison of OTS pedestrian victims age 65 and older across every California county in 2021 and 2023.
Important limit
The OTS category is age 65 and older. It does not describe injury severity, mobility, disability, trip purpose, road design, fault, or transportation access.
2022/2024
A source-preserving transcription of the California Department of Insurance 2025 study for 50 large automobile insurers, covering justified complaint ratios and counts for 2022-2024.
Important limit
The study covers 50 large automobile insurers in the CDI table, not every insurer or insurance product in California.
Current source registry; record periods vary by source
A 60-city directory linking Hurt Advice location hubs to reviewed California government records with source scope, limits, request fields, and official URLs.
Important limit
The index identifies useful official starting points; it is not a complete inventory of every agency, record series, roadway custodian, court file, medical record, or insurer document relevant to an event.
Illustrative city comparison

Statewide context
These legacy estimates are retained for continuity with the city profiles. For verified official figures, use the OTS county explorer above.
These are illustrative California estimates informed by public traffic-safety data families (California OTS, NHTSA FARS, CHP SWITRS) — not official government statistics. The hub currently references illustrative 2024 figures.
Legacy estimate source trail
The city cards and statewide estimate panel use illustrative 2024 figures informed by California traffic-safety data families. They can show broad patterns, but they do not prove fault or predict the value of an individual claim. Use the linked city records, planning tools, and legal guides when your question depends on a specific incident. Use the verified evidence explorer above when you need reproducible OTS counts or a reviewed agency source.

Data-backed next paths
This keeps the accident-statistics hub from being a dead-end data table. The priority links below move readers into exact city-service guides, value tools, and case-action paths.
Use these local guides when statewide data raises a city-specific question about roads, injuries, records, or treatment.
Sideswipe and lane-change questions often become clearer after comparing roads, witnesses, photos, and insurer fault arguments.
City data should hand readers into a concrete legal guide, value tool, or intake path when the research turns into a live claim.
Value
Estimate damages after reviewing city data
Use the calculator when crash context needs to be translated into treatment costs, wage loss, and value questions.
Guide
Read the California car accident guide
Use the broad guide when the claim type is still unclear and the reader needs the main liability framework.

Move to intake when data, injuries, and insurer pressure are already tied to a real accident.
Accident statistics FAQ
These answers keep the page useful for research while making it clearer when the right next step is a guide, a city profile, or a case review.
The county explorer reproduces 116 California Office of Traffic Safety county-year rows for 2021 and 2023, and the local source finder links to 74 reviewed government records. Each result preserves its official source link. The separate 48-city comparison cards are clearly labeled illustrative estimates.
Start with the verified county explorer or local source finder when you need official evidence. Use the illustrative city comparisons only for directional context, then open the city profile for its assumptions and source pathways before choosing the next guide.
No. City-level risk data helps frame local conditions, but claim value still depends on injuries, liability, treatment, insurance coverage, and the specific evidence in the case.
This hub is a research surface first. It helps you compare cities and understand traffic-safety patterns. If the case is already active, deadlines or insurer pressure are usually a reason to stop browsing and start intake.
The verified county dataset compares official OTS rows for 2021 and 2023 and was last reviewed on 2026-08-24. The separate directional city estimates remain labeled 2024 and are not official statistics.
Need help after reviewing the data?
City crash data can help explain the local environment, but it cannot answer who is liable, what coverage applies, or how to handle the insurer. If the case is already active, call or start secure intake now.
Why people trust this step
Keep the research path available, but do not let a live claim stall inside the data.
You can always come back to the city profiles later. The higher-risk mistake is waiting too long on treatment, statements, or filing deadlines.
The county explorer and local source finder above use the verified public datasets linked from each result. The separate city cards and statewide estimate panel are illustrative estimates informed by public traffic-safety data families — not official government statistics or a peer-reviewed study. Treat them as directional context for understanding local crash patterns; methodology and reporting years vary by source, so they should not be cited as official counts for any specific intersection, city, or claim.

Use this data
The public datasets are reusable with their source and limitation language intact. The city widgets are also available, but those figures must be described as illustrative California estimates, not official statistics.
