Radar: Speed Cameras & Limits

Know the speed limit. See the cameras ahead. Plan your drive.

Radar brings speed camera alerts, road speed limits and a GPS speedometer together in a clear, modern driving app. Check your current speed and distance to the nearest control at a glance, whether you're commuting, exploring a new city or planning a road trip.

A clearer view of the road
* See your GPS speed, the available speed limit and the nearest enabled control in one compact display.
* Follow your vehicle on the map with a driving-direction view, or explore freely.
* Choose km/h or mph and international or American speed limit signs.
* Use the head-up display (HUD), including a mirrored view for windshield reflection at night.

More than speed cameras
Browse mapped speed cameras, average-speed / section controls and red-light cameras. Radar also supports mobile phone, seatbelt and following-distance controls, access restrictions, vehicle height and weight controls, toll controls, traffic checkpoints and other recorded enforcement types.

Choose which types matter to you. Disabled types are excluded from proximity alerts and the live information overlay. Set a shared warning distance for your enabled controls.

* Advanced search: Find addresses, cities and places with autocomplete and recent searches.
* Route planning: Compare available alternatives by travel time and distance. Avoid highways, toll roads or ferries.
* Controls along your route: Review cameras and other mapped controls before you leave, with available road speed limits displayed along the route.
* Street View previews: Inspect a control's location and surroundings before you arrive, where imagery is available.
* Google Maps integration: Keep your speed, speed limit and distance to the nearest enabled control visible in a floating overlay while using Google Maps for navigation. Tap the control in the overlay to open its details in Radar.
* Sound and voice alerts: Get audible proximity and speeding warnings, adjust your speeding tolerance, and hear speed limit changes spoken aloud.
* Custom HUD settings: Choose layouts, colors and extra trip information for your head-up display.

Plan in Radar, then launch Google Maps for turn-by-turn navigation. Prefer driving without a destination? Follow your position on Radar's map without route instructions.

Worldwide data, with offline camera access
The included road control database works offline. Speed limit data downloads as needed and is cached on your phone for reuse. Search, route calculation, online maps and Street View need an internet connection. Coverage and accuracy depend on available data; not every road or control is recorded.

Mobile patrol locations are simulated from road geometry, not live police reports. Radar uses GPS and mapped data; it does not detect radar signals. Always follow posted signs and local laws.
