Ride Check

See the reported crashes along a ride, walk or run in California, where they cluster, and what usually goes wrong at each place. Built from the same police crash records as our maps.

A ride, walk or run from Strava, Garmin or any GPS app, or a planned route. Your file never leaves your device, and we cut 200 m off each end before showing anything, since rides usually start and end at home.

What this can't tell you

These are places where crashes were reported, not a measure of how dangerous your route is. We don't know how many people ride or walk each street, so busy streets always show more crashes. Crashes nobody reported to police, and many in Los Angeles, San Francisco and Oakland, aren't on the map.

Crashes count as along your route when they are within 25 m of it. How the data works
