Laser Jammer Tests
Laser Enforcement
A growing trend today are police departments moving to laser (lidar) enforcement and it is estimated that there are over 50,000 police laser guns in use today in the USA.
These guns transmit a beam of infrared light at a frequency of 330 terahertz. This light beam is only 18 inches wide at 500 feet and gets smaller as you approach the officer.
This narrow light beam is aimed by the officer to a reflective area on your vehicle, such as your headlamps or front license plate. The officer can only use the laser gun while he is stationary.
Unless your radar detector is within this 18″ circle, or it picks up “scatter” from the beam, your radar detector will never alert. And by chance it does, it is too late as the officer has already obtained your speed.
Therefore “NO RADAR/LASER detector is effective against this type of traffic enforcement.”
The use of lidar varies from state to state. As an example police in Hawaii use laser exclusively. Florida is split 50/50, with most local police departments using laser and highway patrol officers using radar. In Pennsylvania, police laser guns are not used at all.
Laser Countermeasure Devices
There are several products that are available that can protect you however against police laser.
VEiL Stealth Coating
When police target your vehicle with a lidar gun, they normally target the front, and aim at either the headlights or license plate.
The VEiL Stealth Coating was developed to reduce the reflectivity of police lidar, when applied to these areas.
During our last test of the VEiL stealth coating in November of 2014 it was found to reduce the range of a police laser gun as much as 70%.
If your radar detector is mounted correctly so it does activate to a laser alert, the extra time it will take for a laser gun to acquire your speed with the VEiL, may save yourself from a citation.

Laser Jammers
First off there are two basic types of laser jammers, active and passive.
Passive Jammers: Passive jammers claim that they can disrupt a police radar and/or laser signal by reflecting back to the officers gun. These passive devices do not work, and Radar Roy is so confident that they will fail in protecting you, that he is offering a $5000.00 reward to anyone that can show him a passive jammer that does work.
Active Jammers: On the other hand, active laser jammers are very effective in jamming police laser.
Once an active laser jammer senses the presence of a police lidar beam it activates and sends out its own light beam, overpowering the police laser gun.
I explain my theory this way: “I shine a hundred candle power flashlight at you and you respond by shinning a million candle power flashlight at me. Your more powerful flashlight washes out mine”
All quality active laser jammers are designed to mount in the grill area of your vehicle and you can purchase additional heads for rear mounting.
As police target either the headlamps and/or front license plate you should consider models that have two or more heads that would mount between your headlamps and the license plate.
If you drive a larger vehicle such as full sized SUV, you should also consider a model that has four heads to provide the additional coverage.
There are several active laser jammers on the market today and Radar Roy recommends that you review his laser jammer testing reports so you can select the product best for you.
The Top Laser Jammers made today, include:
- AntiLaser Priority Laser Jamming System
- The Blinder HP-905
- The Laser Interceptor (Currently out of production)
There are no federal prohibitions of laser jammers, as laser is controlled by the U.S. Food and Drug Administration under CFR 21, subpart 1040, 1041 for eye safety.
However states have enacted laws banning the ownership, sale and use of laser jammers they are Minnesota, California, Utah, Colorado, Illinois, Nebraska, Oklahoma, Virginia and Washington DC.
