well first i wasnt speeding , i was the only car out it was 1:15am when he wrote the ticket he gave me a moving violation cuz he couldnt prove my speed and yes he is calling the speed sign a device which would kinda make sence if i was but he said when he gave me the ticket that he is a certified laser and (soemthing) operator which in his words he said that he is trained to see how fast your going... :/ but yes i do plan on going back and measuring cuz it was maybe a block if not a block and 1/2 and i drive a cavalier not that fast yet! lol but another factor is i have exhaust on my car so it makes it sound like ur going faster then u rly are u know thanks for all the help and non help i will keep posted thanks again.....
