I really don’t think you use real rader. Second time I recieve ticket and only times in my 30 years of driving. last time at red light with car stopped. as soon as it turned green i was pulled over for speeding 65 mph. 10 year old son even started to argue with cop. Tn plates this time. Tried to explain to husband and after reading other posts now he believes me. who can drive 6 hours to fight it. You know where they can stick their traffic school tto. i took the increase in insfurance on my good driver record. thanks summersville
