This is a school zone and the police like to stand in the center median to catch speeders. They will pull you over in the Church parking lot on the East side of Preston about 1 block after you pass the officer in center grass median. Particularly a bad ticket, as it’s in a school zone and it will cost you points on your driving record. They like to hang out there when there is no school going on during that day, but you still have to obey the limit.
