Have you ever gotten a speeding ticket thanks to a pesky radar? Some one million people receive speeding tickets every day; the cost of the average speeding ticket comes out to $150. A full 16 percent of drivers will get a speeding ticket this year and 95 percent of these drivers won’t contest their tickets. So, how exactly does a radar work? It uses waves to detect distance and speed of objects based on the doppler effect. A transmitter oscillates an electrical current through an antenna to an amplifier by using a radio wave.

The radar speed gun invented by Bryce K. Brown of Decatur Electronics in March 1954, and was first used in Chicago, Illinois in April 1954. Here’s man’s effort to combat machines—radar detectors have been helping heavy footed drivers avoid speeding tickets since the 1970s. Illegal detectors take an active role in eluding police. They have their own radio transmitter that emits a jamming signal. The signal replicates the original signal from the police radar gun and mixes it with additional radio noise, creating a confusing echo signal.

Radar detector is completely illegal in Virginia and Washington, DC. Use of a radio jammer could lead to felony charges, fines, and jail time. Police officers use Spectre ELITE to detect hundreds of radar detector models. What are the best detectors then for speeders? To learn the answer, check out the infographic below.
