Laser jammers are not legal in Tennessee. Tennessee law prohibits all radar and laser jamming, and police can confiscate the devices. Violations of this law are Class B or Class C misdemeanors.
Although police can use radar or laser guns to determine your speed, there are clear differences in how they are used and the laws governing how drivers can protect themselves from speeding tickets. Laser signal blocker are illegal in 10 states, including Tennessee, and legal in 40 other states. Some states have passed their own laws prohibiting interference with police laser guns.
They are legal in 40 of the 50 states, but illegal in 10, including California, Colorado, Illinois, Minnesota, Oklahoma, South Carolina, Tennessee, Texas, Utah and Virginia.
Laser jammers fall under the jurisdiction of the FDA(Food and Drug Administration), and there is no federal law prohibiting the use of police laser jammer. However, some states have laws banning laser jammer.
If caught, the penalty is usually fairly minor, similar to a repair ticket, such as being too dark in tone or not running the front board (if you should).
