I was on 75 in Fairfield, TX and there are at least three different speed limits within a half of mile. You will always get a ticket because it is not possible to reduce your speed as there was no warning to let you know that the speed was changing. The officer asked me first question if I was from out of town. I knew I was getting a ticket. He also made sure he said I was over by 11 miles to raise me to next fine. I also only had three weeks to appear in court. I tried almost everyday to called the courts to find out information to reset court date or information about Defensive Driving Safety Course. The officer gave me a paper with the acceptable fines. There was a number on there, but I never once got a live person and I left a lot of messages and no one ever return my call. Further the paper said to see the other side to find out information about the Driving Safety Course. The only problem is that the other side was blank. The only number that worked was the one, which you can make a payment to pay for the ticket. This is a more than a speed trap, but I feel it border line illegal. Please be careful, but really no way around avoiding a ticket.
