A laser jammer is a device designed to produce a "no response" or cosine error when a police officer directs a laser radar gun towards a vehicle. By displaying this error, the laser radar gun fails to provide any indication to the police officer whether the vehicle is equipped with a laser jammers or if their aim is simply off target.

A laser signal jammers is a tool that produces a "no response" or cosine error signal when a law enforcement officer directs a laser radar gun towards a vehicle. This error signal prevents the police officer from determining whether the vehicle is using a laser jammer or if they are not targeting the vehicle accurately.

How to jam police lasers?

In order to counteract the effects of a laser, it is essential for the front laser jammers to safeguard the headlights, license plate, and the reflective surfaces in their vicinity. Conversely, at the rear, the license plate and tail lights become the main focal points. Additionally, the center high-mounted stop light, backup lights, and vertical reflective surfaces are also susceptible. Surprisingly, even a spare tire/wheel assembly mounted on the tailgate can be targeted, as demonstrated by our successful attempt at hitting a Jeep Wrangler's aluminum spare wheel from a distance of 2,500 feet.

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?

Police radars mounted on the dashboard have the capability to detect the speed of multiple vehicles simultaneously, often up to two.

Presently, radar technology allows for the simultaneous targeting of multiple vehicles, enabling the identification of the fastest vehicle in a group as well as the vehicle with the emest radar signal reflection. However, visual determination by the officer is still necessary to determine the fastest vehicle among those targeted.
