From another forum:
Anyone know which jurisdiction this is? The OP lives in Ohio.It is possible for a trained officer to know when a lidar jammer is in operation. I know of one jurisdiction where when a vehicle with a lidar jammer is discovered, the vehicle is impounded pending a "trained mechanic" availability to remove the jammer. The driver is charged with "interfering with the lawful duties of a law enforcement officer", a misdemeanor, not a traffic offense! Ouch!
