Navigation apps are great at getting you around an accident. But they can only help once you're already in the car. Detours works before that. When CHP logs an incident on your route, Detours sends you an alert — while you're still home, still deciding. Leave a few minutes early. Take the street you know. Or just grab another coffee. Think of it as the app you check before you open your navigation app.
Live California Highway Patrol incidents statewide — crashes, hazards, fires, and more — plus Caltrans lane closures, traffic cameras, and chain control status, all in one app. With Pro, get push alerts tuned to your route and schedule, and a Commute Report before you leave.
Built on the official CHP CAD feed and Caltrans's public lane closure, traffic camera, and chain control data, refreshed continuously, with smart alerts that respect your time.
Every active CHP incident plotted in real time, alongside Caltrans lane closures — distinct markers, zoom-aware clustering, so you always see the full picture.
See what's closing on your highways up to 3 days ahead — planned Caltrans lane and road work, before you're stuck in it.
See Caltrans cameras on the map and in a list, and near any incident. Tap Play for live video where available. Pro adds favorite cameras and earlier images with a time-lapse.
Pin your mountain highways and see the chain control status Caltrans publishes, in Caltrans' own terms, free for everyone. Pro adds an alert when the level changes on a highway you pick.
Get notified for incidents on your highways, within your alert area, at the severity level you choose, plus chain control changes on the mountain highways you pick — only when you want them.
One summary of what's active on your roads, at the time you choose. Nothing is sent when no incidents match.
Draw a polygon around your neighborhood, commute, or any area you care about — alerts only fire inside your zone.
Create named alert windows by day and time — commute hours, weekend mornings — and silence everything else automatically.
Track any incident on your Lock Screen and Dynamic Island — live updates as the CAD log evolves.
