The officer pulled me over after he observed me trying to get over into the slow lane to allow a speeding vehicle to pass. He then pulled out and casually rode and then decided to stop me. I told him that I thought the speed was 75 and that I was only trying to get over to the slow lane. He said the speed changes when you get into Louisiana and that I was doing 80 in a 70 zone. I know for fact I was doing 75. The officer was rude about it and offered no other reason when there were cars passing and shaking my vehicle from there speeds.
