Two nights ago at 8.30pm I was caught by radar for driving at 75mph in a 65mph zone on US22 outside Huntingdon, TN (rural four lane divided setting). The police officer was sitting in the median, lights off. At the time I passed him I was driving 68mph. My cruise control had been set to 68mph for some time. I may or may not have momentarily accelerated to 70-75mph on a long, straight stretch of road prior to passing the police cruiser, I honestly can't remember. But if I did it would have been only for 5-10 seconds at the most. Interestingly, the police officer made no attempt to catch up with me at first. He waited until half a mile down the road to pull me over inside a 55mph city limit zone...by which time I had lowered my speed to 55mph. The weather was clear and dry and there was hardly any traffic around. Should I go to court to challenge the ticket? (I have one previous speeding ticket - 3 points - from 18 months ago).
Also, how do I find out if a speed limit on any particular road is "absolute" or "presumed"?
