Typically enforced weekdays evenings between 3:00 and 6:00 pm as heavy traffic from Kansas City and Lawarence returning to Topeka. 1st know that the KS Hwy Patrol are generally lazy and stick to the ususal spots. Local frequent turnpike users know where these hot spots are and slow down. This particular location is 5 miles east of Topeka. Rarely is there any speed enforcement west of this area and the locals run 80~90 MPH. That leaves unsuspecting travelers who get tuned into the flow of traffic then do not slow down nor see the hwy patrol laying in wait hidden from view behind the landscape. Tip for those traveling this area. Find someone with Kansas Tags with the letters “SN” or “DG” in the upper right corner. They are locals. If they slow down for any reason follow suit.
