California intersections ranked by reported crashes

4,272 surface-street junctions across 187 cities and 30 counties, ranked by crashes reported in 2023, 2024 and 2025. Every location has been checked against a second, independent source; the ones that could not be confirmed are not here, and the rate at which that happened is published below rather than hidden.

Read it as a ranking of busy places before you read it as a ranking of dangerous ones. Nothing here is adjusted for traffic volume or population, and nothing here says anything about any individual claim.

The hundred busiest, statewide

Every junction below recorded at least 53 crashes across 2023, 2024 and 2025. The complete list for any one place is on its own page — by city or by county.

The ranking covers 2023–2025. The 2026 figures are separate. They run from January to August 2026 — every whole month the state has published so far — and they are not part of the ranking or of any total above. Police agencies file at different speeds, so putting a part-reported year in a ranking would order agencies by how fast they file rather than roads by how often they are hit.

Recent months are still filling in, so treat them as a floor rather than a count. August 2026 held about 48% of what that month averaged across 2023–2025 when this data was compiled, so its real total will be higher. September 2026 is left out entirely: the state's file stops on 2026-09-01, so that month holds 15 records — a part of a month rather than a month that is late being filed.

Reporting runs at different speeds from one police department to the next, so this matters more than the statewide figure: every city in this ranking together has filed 139,252 crashes for January–August 2026, against about 166,407 predicted by the same 2023–2025 crash rate — roughly 84%. So "none reported yet" in the 2026 column means no report has arrived for that junction, which is not the same as no crash happening there.

City pages

The full confirmed list for each city with at least 10 confirmed junctions, and that city's own confirmation rate. Cities below that appear in the ranking above and on their county page, but a page of three rows is not a ranking.

Every county

How these locations were established

The coordinates are geocoded, not surveyed. A crash report names a primary road, the nearest crossed road, and a city. It does not carry a verified junction location. Turning those names into a point on a map is an inference, and inferences can be wrong.

So each one has to survive three checks before it appears here:

  1. The US Census geocoder must return a point for the two road names in that city.
  2. The address it echoes back must name the same city and both roads. This catches the failure where a geocoder quietly substitutes a similar name somewhere else — one request for a Berkeley junction came back as a street in Thermal, 746 kilometres away.
  3. A second, independent source must agree to within 50 metres — either the coordinate carried on the crash records or, where those are absent, an OpenStreetMap-derived geocoder. Where the two disagree, the junction is dropped. It is never averaged, and never settled in favour of whichever source has more records behind it.

That rule is not caution for its own sake. In Moreno Valley, 48 crash records agreed on a coordinate 3.3 kilometres from the real junction, with no internal disagreement to give the error away. In San Jose, the crash-record coordinates are displaced by roughly 33 kilometres. Both would have looked entirely solid to anyone trusting a single source.

What was rejected

Where the two sources did agree, they agreed closely: the median gap is 9 metres and nine in ten are within 26 metres. Separately, 261,602 crash records in these cities were set aside before any of this began because they name a freeway, ramp, or state route.

How precise these counts are

Not very, at the bottom of the table. Crash counts at a single junction behave like any other count of rare events: a junction whose true rate is ten crashes a year will record somewhere between about four and sixteen in a given two-year window without anything changing on the ground.

So a difference of two or three crashes between neighbouring rows is not a difference at all. The junctions at the top of this page are far enough apart to mean something; two junctions separated by a single crash are, for practical purposes, tied.

Coverage by city

How many junctions were confirmed in each city, out of those attempted. A low rate means the sources disagreed there, not that the city is safe. Ontario, San Jose, Santa Rosa and Redding produced nothing that could be confirmed and do not appear in the ranking at all.

What this ranking does not tell you

Common questions

Is this a list of the most dangerous intersections in California?
No. It ranks junctions by how many crashes were reported at them, and busy roads produce more crashes than quiet ones. Nothing here is adjusted for traffic volume or population, so a junction near the top is carrying a lot of traffic at least as much as it is carrying risk.
How were the locations worked out?
They were geocoded, not surveyed. The crash record names two roads and a city; the coordinates come from the US Census geocoder, and each is published only if a second, independent source agrees to within 50 metres. Where the two disagree the junction is dropped rather than guessed at.
How precise are these counts?
Less than they look. A junction that averages ten crashes a year will record roughly four to sixteen in any given two-year window purely by chance. Treat a gap of a few crashes between neighbouring rows as no gap at all; only large differences mean anything.
Why is my city missing, or thinner than I expected?
A junction only appears if two independent sources agree on where it is. In some cities the coordinates carried on the crash records are systematically wrong — in San Jose they are displaced by about 33 kilometres — so nothing there could be confirmed. Some cities also record cross streets so precisely that crashes never concentrate at a named junction, which is a reporting difference rather than a measure of safety.
Why are there no freeway junctions?
They are excluded deliberately. A freeway pairing gathers crashes along a length of road rather than at a point, so a single coordinate would misrepresent it, and every geocoder tested resolved at most one in fifteen of them correctly.
Does a crash at one of these junctions affect my claim?
No. How often a location appears in a statewide table has no bearing on fault, insurance, or outcome in an individual crash. That is decided on the evidence in that case, not on a ranking.
