Mobile radar at top of the hill says 35 mph, then 100 ft past that is a school sign showing 25 mph with time limits, 50 ft past that is a sign saying 35 mph. Even if you pass 5 mins past the 25 mph cut off they will ticket you as speeding in a school zone. So lets say you are going 35 mph at 3:31 and the cut off time is 3:30 you get a ticket for speeding in a school zone. If you look at Google Maps on street view you will see them sitting out there but not in front of the school. They are past the school on both ends.
