This is a Photo radar trap that is hidden in what looks like an electrical box. When you look at it you will notice that there is a small metal arm with a camera at the end of it popping out of the top of the box. You are given some warning, about 2 meters ahead there is a white and green sign saying to reduce speed. But it is small and is placed on the ground so it is very hard to see. Note: It isn’t always in the same place.
