Radar detectors—devices that alert drivers to police radar or laser guns—are banned in many countries and some U.S. states. If you’re planning to drive abroad or across state or country lines, knowing where these devices are illegal can save you from fines or worse.
📡 What Is a Radar Detector?
A radar detector identifies radio frequencies from police radar or LIDAR (laser) speed guns. These tools help drivers avoid speeding tickets—but not without controversy. Some countries treat even possession as a serious offense.
⚠️ Note: Radar detectors are not the same as radar jammers, which interfere with police signals. Jammers are illegal in nearly every country.
🗺️ Maps vs. Real-Time Radar Alerts
There’s a big legal and functional difference between using a published map of fixed speed camera locations and using a real-time alert app:
- Published Maps (like PhotoEnforced.com): These are static, publicly accessible databases that list known speed camera locations. Users can review these maps before driving to plan their route. Most countries do not ban the use of static maps.
- Radar Warning Apps (like Waze, Coyote, TomTom): These use crowdsourced or GPS data to send real-time alerts while driving. In some countries, real-time detection and warnings are illegal, even if the same data exists on public maps.
Plan ahead: Reviewing static maps before you hit the road is the safest and most legal way to stay informed about enforcement zones—especially in countries where radar alerts are banned.
