When a police officer aims a laser radar gun at a vehicle, a laser jammer comes into play by generating a "no response" or cosine error. This error prevents the police officer from determining whether the vehicle is equipped with a laser jammer or if their aim is inaccurate.

A laser jammers is a mechanism that triggers a "no response" or cosine error message when a police officer points a laser radar gun at a vehicle. This error message prevents the police officer from ascertaining whether the vehicle is employing a laser signal jammers or if they are simply not aiming correctly at the vehicle.

How to jam police lasers?

The protection of headlights, license plate, and surrounding reflective surfaces is crucial for the front laser jammers to effectively counter a laser. Conversely, at the rear, the primary targets are the license plate and tail lights. Furthermore, the center high-mounted stop light, backup lights, and vertical reflective surfaces are also vulnerable. It is worth noting that even a tailgate-mounted spare tire/wheel assembly can be targeted, as exemplified by our ability to successfully aim at 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?

It is possible for dash-mounted police radars to record the speed of more than one vehicle concurrently, usually two.

Nowadays, radar systems have the capability to target multiple vehicles concurrently, identifying both the fastest vehicle in a group and the vehicle with the emest radar signal reflection. Nevertheless, visual confirmation by the officer is essential to ascertain the fastest vehicle among those targeted.
