Is this a cop?
Practice only. Your answers stay in this browser and aren’t recorded.
Radar demo. Blips are a demo, not real police locations. How this works
Loading community totals…
Spot the tells
Push bar
Steel frame on the front bumper.
Spotlight
Round lamp by the driver’s mirror.
Antennas
Two to four on the roof or trunk.
Steel wheels
Plain black rims, small chrome caps.
Fleet colors
Black, white, charcoal, navy.
Heavy tint
Hides the gear. Weak on its own.
It watches cops. Not you.
- Police vehicles
- Plates
- Faces
- You
Faces and plates are removed or obscured before an image reaches the labeler, then checked by people. That is careful, not perfect, so report any image that slips through. No plate search. No private-person tracking. No ad trackers.

Radar map
To draw the map behind the homepage radar, Cloudflare, which serves this site, estimates a rough area from your IP address through our copdar-local-radar.crecker19.workers.dev endpoint. We round it to 0.1° (about 10 km) and send it only to your browser. Copdar doesn’t store it, write it to logs, or use it in analytics. The radar’s blips are a demo, not real police locations.
Your browser then loads up to 9 map images for that area directly from OpenStreetMap (tile.openstreetmap.org). Like any website, OpenStreetMap receives your IP address, browser details, copdar.org as the referring site, and which map squares were requested, which reveals that rough area. See the OSMF privacy policy. With a VPN or some mobile networks the area can be far off. If no area is available, you see the demo radar with no map.
