Riverside County crash explorer

How to use the explorer

• Pick a year range, a city or the whole county, and whether to show all injury crashes or only fatal ones.
• Add filters such as pedestrian, bicyclist, hit-and-run, DUI, after dark or freeway. Filters combine.
• Click a bar under Type of collision, Primary cause or Crashes by city to narrow every other chart to it. Click it again to clear it.
• Hover over the year bars, the hour grid or the map for exact counts. Show as a table lists the same numbers.

About this data

Source. The California Highway Patrol's California Crash Reporting System (CCRS), published on the State's open data portal (data.ca.gov). CCRS holds crash reports submitted by the CHP and by local police departments and the Sheriff. We downloaded the Riverside County records on September 18, 2026.

What is included. Crashes in which at least one person was injured or killed, 2016 through 2026 (102,494 crashes). One record per crash; records the CHP marked as deleted are left out. Crashes with property damage only are not in the explorer; the 2024 total at the top of this page includes them.

Gaps and cautions.

• 2019 is missing. The CCRS file for 2019 covers only January to April statewide, so it would badly undercount. It is shown as a gap.
• 2025 may still rise. Its fatal-crash count is well below earlier years, which usually means reports are still being added.
• 2026 is year to date (through the download date).
• Not every crash has map coordinates. Crashes without them are counted everywhere except the map.
• The "primary cause" is the officer's entry on the report (a Vehicle Code section). It is not a court's finding of fault, and it can be disputed.
• Counts are raw numbers, not rates. Larger cities and busier roads will show more crashes.

Privacy. The explorer never shows an individual crash. The map groups crashes into squares about 1 km across and hides any square with fewer than 3 crashes in the current view.

Why crash data can matter after an injury

Crash patterns can help show that a road, intersection or signal was a known problem. If a public agency may share the blame, a written claim is generally due within six months (Gov. Code § 911.2); see claims against government. For your own crash, start with the report itself: our crash report guide explains how to get it from each agency.
