The question of legality has risen at different points in time

Before the laws created regulations for these machines, many individuals have used them to ensure the avoidance of tickets and law enforcement for a variety of reasons. Some of these detectors may have monitors in place to record speeds of the vehicle they are installed in or may provide information on where and how far a police squad car is. Some incidents have resulted in these machines being used against the drivers as evidence.

For those situations when the driver has committed a traffic violation, radar detectors may be used as evidence in a court case. When laws and regulations are unknown, it is essential to obtain a lawyer for all relevant information. Some states only allow specific devices for use in the vehicle, and others do not allow any of these detectors at all. It is vital to know what law is present in the state the driver is traveling through. When the legal devices are used in those states that allow them, they often assist in avoiding traffic tickets and citations. It is important to ensure only the right one is installed to prevent legal entanglements.

Some Radar Detectors are Legal

The most important point in having a radar detector installed is when the driver has been stopped by law enforcement. If the device is legal, then there should be no issues after all questions have been answered. However, if the machine is not legal, the officer may use this detector as a means of arrest or involve further legal entanglement. The Light Detection and Ranging radar detector or LIDAR is usually the only device permitted by law. Some states do not allow these in commercial or big rig trucks and vehicles with weight limitations of over 10,000 pounds for these specific transporting machines.

For some states, these detectors are legal and permitted even by law enforcement. There is speculation about the ability to speed with the notice these machines allow when someone is driving, but if the drivers are safe even when speeding they usually are not reported even by other drivers. Some arguments are for these devices due to the inaccurate reads some police radars give when monitoring traffic. Despite the pro and con for and against these radars, they are permitted in passenger vehicles in some states provided that only the legally purchased and allowed devices are installed.

Why are Some Police Radars Inaccurate?

When defending against a ticket or traffic violation due to speeding, it has been found that some of the radars used by law enforcement have inaccurate reads depending upon certain factors. Some of these common reasons have been discovered. Nearby signals in the air have caused interference with these radars and they cause inaccurate numbers to appear to police. When the laser devices are not properly angled and pointed, a faulty read often appears. For some law enforcement officers, training may have been inadequate or rushed with may lead to issues with a moving target. When the devices are not maintained properly, they may break down just like any other electronic object.

Other Avoidance Techniques against Police May be Illegal

Jammers against laser devices and radars inside a consumer automobile have been listed as illegal in most states. These machines interfere with the signal and are not permitted by law. When they are used, severe and harsh penalties are often the outcome. Some versions of coatings upon the vehicle have been listed as illegal as they cause a type of stealth that allows avoidance from laser systems. The coating used often alters the accuracy of police devices.
