If you see the signal, you can release the throttle and hit the brakes to reduce your speed.

How far can a radar gun detect your speed?

Detection range can be as low as 100 feet or less to over a mile. A radar may track a distant large vehicle instead of a closer small vehicle without any indication to the operator which vehicle the radar is tracking. The angle between the radar or lidar and target must be small for an accurate speed measurement.

How do radar detector detectors work?

Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly. It is therefore possible to build a radar-detector detector, which detects such emissions (usually the frequency of the radar type being detected, plus about 10 MHz for the intermediate frequency).

How far do radar detectors work?

An X-band radar has a low-frequency and high output, making it relatively easy to detect objects from 2 to 4 miles away. However, devices other than police radars generate X-band signals, including garage door openers and microwave towers. K-band radar is most commonly used by police and has a small wavelength.
