Another ploy that is used here. The fixed cameras have a post for the camera, another for the flash, and a loop in the road to sense when the offending car is in focus.
It did not take the truckers, that run at night, long to realise that if they ran on the wrong side of the road, the camera did not work.
So at night, it is normal to see a 60tonn B double truck doing 100k, in a 60k zone, comming down the wrong side of the road, towards you.
