A radar detector is an electronic device designed to detect the presence of radar signals emitted by police or other speed enforcement devices. By providing an early warning of an approaching radar signal, a radar detector can help drivers avoid speeding tickets and other penalties.
Radar detectors have been around for decades, and they have become increasingly sophisticated over time. Modern radar detectors are highly sensitive and can detect radar signals from a long distance away. Some radar detectors also include features such as GPS tracking and lane departure warnings.
