What Are Laser Jammers for Cars and How Do They Work?

Laser Jammers Keep you Protected on The Road

When you’re driving, you may occasionally notice a police officer off to the side, pointing a device at passing cars. This is a laser gun fashioned to note the speed of a vehicle and allow officers to catch anyone going above the allotted speed limit. These devices work quickly, so even if you notice an officer using a laser gun, you may not have time to adjust your speed accordingly.

Sometimes it can be hard to keep up with changing speed limits, which puts you at risk for a speeding ticket. There’s nothing worse than getting unexpectedly pulled over, especially with the hefty price of a ticket. That’s where laser jammers come into play! A laser jammer is a device you can install in your vehicle that sends a “no response” error message when a laser gun attempts to scan the speed of the car. This gives you time to adjust your speed and may prevent you from getting pulled over.

How Do Laser Jammers for Cars Work?

It’s important to remember that police laser guns are incredibly accurate. These devices transmit a beam of light on the infrared light spectrum that bounces off your license plate or head light, allowing the device to get an accurate speed reading in milliseconds. Even when traffic is busy, it can narrow down on a single vehicle and clock your speed.

Laser jammers detect the laser coming from law enforcement laser guns; however, instead of the laser transmitting your car’s speed back to the laser gun, the jammer sends its own laser to block the gun from receiving any speed information. Basically, a laser jammer confuses the signals coming from the laser gun, making it incapable of getting an accurate speed reading.

Have a radar detector on your car and hope that’s enough? Radar detectors don’t detect laser guns, only radar guns. Using a laser jammer or shifter alongside a radar detector gives added security measures for your vehicle.

Laser Jammers vs Laser Shifters

Laser jammers and laser shifters are pretty similar, and sometimes these phrases are used interchangeably. Jammers and shifters perform the same task - they both detect and protect against law enforcement laser guns. However, whereas laser shifters are installed on the outside of a vehicle, laser jammers are on the inside.

Maintaining your laser jammer or shifter is imperative to ensuring they function properly. When you are getting your device installed, note whether your vehicle has the firmware updates that a laser jammer requires to work. This technology is always changing, so finding the right device for your vehicle ensures you get the best bang for your buck!
