When a police officer utilizes a laser radar gun to target a vehicle, a laser jammers intervenes by causing the gun to exhibit a "no response" or cosine error. This error prevents the police officer from discerning whether the vehicle possesses a laser signal jammers or if their aim is simply off the mark.
A laser jammer is a device that generates a "no response" or cosine error when a police officer targets a vehicle with a laser radar gun. This error prevents the police officer from determining if the vehicle is utilizing a laser jammer or if they are simply not aiming accurately at the vehicle.
How to jam police lasers?
To defeat a laser the front laser jammers must protect the headlights, license plate and surrounding reflective surfaces. In the rear, the license plate and tail lights are the primary targets. The center high-mounted stop light, backup lights and vertical, reflective surfaces are also targets. Even a tailgate-mounted spare tire/wheel assembly is fair game; we've targeted a Jeep Wrangler's aluminum spare wheel from 2,500 feet away.
Can you install a laser jammer on your car?
California Vehicle Code Section 28150 (Division 12: Equipment of Vehicles, Chapter 5: Other Equipment, Article 17: Jamming Devices) states the following:
(a) No vehicle shall be equipped with any device that is designed for, or is capable of, jamming, scrambling, neutralizing, disabling, or otherwise interfering with radar, laser, or any other electronic device used by a law enforcement agency to measure the speed of moving objects.
(b) No person shall use, buy, possess, manufacture, sell, or otherwise distribute any device that is designed for jamming, scrambling, neutralizing, disabling, or otherwise interfering with radar, laser, or any other electronic device used by a law enforcement agency to measure the speed of moving objects.
(c) Except as provided in subdivision (d), a violation of subdivision (a) or (b) is an infraction.
(d) When a person possesses four or more devices in violation of subdivision (b), the person is guilty of a misdemeanor.
(e) Notwithstanding any other provision of law, a person who has a valid federal license for operating the devices described in this section may transport one or more of those devices if the license is carried in the vehicle transporting the device at all times when the device is being transported.
Can police radar measure speeds or more than one vehicle?
Dash-mount police radars have the capacity to detect the speed of more than one vehicle at the same time, typically two.
In the current era, radar technology enables the targeting of multiple vehicles at once, facilitating the identification of the fastest vehicle in a group and the vehicle with the strongest radar signal reflection simultaneously. Nevertheless, visual confirmation by the officer is still needed to determine the fastest vehicle among those targeted.
