On the 4th day 0f June 2017 at 10:21am. I was driving on Highway 167 and Jones Street in Dodson Louisiana. I was driving down-hill with an unloaded semi truck Tractor and trailer. This vehicle is a commercial vehicle for a popular trucking company. I was driving down Highway 167 (a road that had various speed limit signs as you drove down). I went from a 65mph speed zone to a 50mph speed zone. Not far after the 50mph point the speed limit lowers to 45mph and this is where the officer was lurking in a parking lot. Before I had time to adjust my speed I saw police lights in the front of me in a parking lot on my right hand side. The officer pulled me over and said that he had caught me doing 66mph in a 50mph zone. It was clear to me that this officer had set up a speed trap. I was in the process of slowing down when I saw the 50mph sign (which was very obscure). The officer was set up in a position that didn’t give me time to slow down. I asked the officer for mercy based on my needing to drive in order to make a living. He basically told me that if I paid the ticket before the court date then I wouldn’t get any points on my license (which I later found to be untrue). He simply gave me a ticket for speeding without any further conversation.
