Radar detectors are used by some individuals as protection devices from speeding. Some states find radar detectors illegal, so if you are caught with one, you may be fined, prosecuted, or both. This will be in addition to any speeding ticket you receive. Be reminded that speeding is illegal and dangerous. In fact, speeding may not even be worth it. Police departments and agencies are become more and more equipped with their own speed detection radars that cannot be read by radar detectors.

How Do They Work?

Radar can be described as electromagnetic or radio waves traveling through the air. As the waves hit an object, they will bounce back to that which transmitted it. It will then be able to detect how far away the object is. The detectors pick up the radio signals sent by the police's radar device, and then alert you that you are being tracked. This gives you ample time to adjust your speed. Radar detectors are the most accurate when your car is not being directly targeted. Radar detectors do not work if the police officer has a radar gun and is driving directly behind you, or if the radar gun is pointed directly at your car from the front. In these situations, radar detectors will not be able to pick up the waves being sent by the police, so the detectors are not efficient.

Recent Advancements

There are new features you can buy in radar detectors. One feature is called the jamming technique. Jamming the signal is accomplished when the radio signal is picked up by the detector. It will alert you, but also sends back the radio signal to where it came from as a mixed signal. This prevents your speed waves to be read by the police radar gun. Both regular citizens have the option to buy a jamming feature on their detector, but you should know the police have the ability to jam your signal, too.

Lidar guns are the radar guns police use to get around the traditional detector. The guns use laser technology, which is extremely accurate. The lidar guns work by sending out laser signals that bounce off the car and return to the game. The gun is able to take several measurements in a matter of seconds then averages the measurements to find out how fast the car is moving. Regular radar detectors don't even know the lidar guns are out there. The guns are harder to detect with the laser detection. Radar detectors will become more and more obsolete as the police turn to lidar guns.

Technology will continue to improve, and there will be newer and smarter devices created to thwart the police in their duties to protect the people and keep the highway safe. There will also inevitably be new devices for the police to use in blocking the radars and catching those who speed. Make the wise, safe, and smart choice when it comes to speeding.
