One device law enforcement use to measure the expected speed of a moving vehicle is
Radar detectors use a superheterodyne receiver to detect these electromagnetic emissions from the gun, and raise an alarm to notify the motorist when a transmission is detected. False alarms can occur however due to the large number of devices, such as automatic door openers (such as the ones at supermarkets and drug stores), speed signs, blind spot monitoring systems, poorly designed radar detectors and adaptive cruise control, that operate in the same part of the electromagnetic spectrum as radar guns.

The
Radar scrambling
It is illegal in many countries to sell or possess any products that actively transmit radar signals intended to jam radar equipment.[4] In the United States, actively transmitting on a frequency licensed by the Federal Communications Commission (FCC) without a licence is a violation of FCC regulations, which may be punishable by fines up to $10,000 and/or up to one year imprisonment.[5]
LIDAR detection
Newer speed detection devices use pulsed
Despite the advent of LIDAR speed detection, radar remains more prevalent because of its lower price and the amount of radar equipment already in service. In addition, proper use of LIDAR equipment requires the officer to remain stationary in order to beam a very precise signal.
Legality
Using or possessing a radar detector or jammer is illegal in certain countries, and it may result in fines, seizure of the device, or both. These prohibitions generally are introduced under the premise that a driver who uses a radar detector will pose a greater risk of accident than a driver who does not.[
Country | Legality | Comment | Radar Bands |
---|---|---|---|
Australia | Illegal in all states. | They are illegal to use in a moving vehicle (as stated by the traffic laws in) Victoria it is an offence to sell, use or possess a radar detector, and police may confiscate such equipment if found in a vehicle.[8] Heavy fines apply, ranging from AU$200–$1,700, up to nine demerit points, and confiscation of the radar detector. However, importing a unit is permitted under Australian customs regulations. Queensland = up to 40 penalty units (approximately equal to $3,000) for being in or on a vehicle whether or not the device is operating or in working order. Effective October 12, 2020, heavy penalties for drivers with radar detectors apply in WA.[9]

Regardless of whether they are used or not, police there may confiscate radar detectors, operational or not, and impose substantial fines in provinces where radar detectors are illegal.[12] Quebec penalizes $500 CAD for use of a radar detector, along with confiscation of the device.[13] | K, Ka, Laser |
China | Detectors legal, jammers illegal | All radar locations in China are reported and published. Map apps on a phone will report the locations. But all speeding and traffic violation radar or camera are electronic police with a police number as well as a human being police. Using a jammer will be considered as obstructing a police and subject to 15 days imprisonment. Radar jammers are also illegal in Hong Kong and Macau. | |

France | Detectors and jammers are illegal to own, use or sell.[10] | Regardless of whether they are used or not, police there may confiscate radar detectors, operational or not, and impose substantial fines. Since 2012, there are also very strict regulations regarding G.P.S. devices which locate speed cameras. Speed cameras must be signaled as "Danger zones" which are precisely 300 meters long in towns, 2 km out of towns and 4 km on highways.

United States | Law varies from state to state,[28] but detectors are generally legal in private vehicles under the Communications Act of 1934[29] and illegal in commercial vehicles by DOT regulation (49 CFR 392.71 Archived 2006-09-27 at the Wayback Machine). Exceptions:
|
Confiscation and/or destruction of the detector was once a common practice but lawsuits raised by drivers arguing violation of property rights have resulted in temporary removal while a citation is written, then return of the device after its description (make, model and serial number) has been entered on the ticket - usually for speeding and possession/operation of a detector. Use of a radar/lidar detector on a military installation is prohibited. Persons entering a military installation with one visibly mounted to the sun visor or windshield will be asked to remove it and put it away. Those who refuse will be denied entry onto the installation at that time. Military law enforcement may not stop a vehicle solely for a detector being in use, but along with being stopped for another moving violation, active duty personnel using a detector may be ordered to report the violation to his/her unit commanding officer.
